Walking and Cycling Design Guide
1
INTRODUCTION
1.1
Vision
Walking and cycling are no longer merely a functional means to get from one point to another. Instead, it is a multi-purpose and multi-sensory experience. Hence, we envision Singapore to be a city that is safe, convenient, comfortable and delightful for all to walk and cycle. A consistent and pleasant design would encourage active mobility as a popular commuting means, as well as an attractive recreational option.

1.2
Purpose
This book is to guide private developers, the building industry, consultants, and government agencies in the planning and designing active mobility infrastructure. It also provides the considerations behind the standard design of the various infrastructure.
It aims to complement various agencies' technical requirements in active mobility related designs*. Where relevant, the Guide will direct readers to more details in agencies' respective documents.
1.3
Pedestrians & Cyclists' Needs
1.3.1
Pedestrian
ABOVE: Space required by a wheelchair user and a pedestrian
Pedestrians refer to a very wide spectrum of commuters who utilise walkways as a means to travel either for leisure or to connect them to and from facilities. Designers should have a good appreciation of the broad range of needs and abilities exhibited by the various user groups in the community. This would enable them to work towards designing an accessible environment where people of different abilities can co-exist with cyclists, Personal Mobility Aids (PMAs) and Personal Mobility Devices (PMDs) to commute safely and independently.
The key groups of users include:
Infants and Children
Expectant Mothers
Older Persons
Wheelchair Users
The Ambulant Disabled
Persons with Visual Impairment
Persons with Hearing Impairment
For greater understanding of the above listed profiles, please refer to BCA's Universal Design Guide for Public Places (2016).
ABOVE: Wheelchair user and other users waiting at pedestrian crossing
1.3.2
Cyclist
The ideal condition for cyclists is to have a dedicated route where there is less variation of speeds among the users. However, due to space constraints, cyclists may need to share space and interact with other users.
A bicycle needs a minimum space of 0.75m width by 2.45m length, which is equivalent to 3 walking pedestrians. When in motion, cyclists will require more space than pedestrians because of the natural lateral movement to balance. Depending on the cycling speed, an additional space of 0.2-0.8m will be required. The recommended safety comfort distance from other cyclists is 0.5m (Sustrans, 2014).

1.4
Fundamentals of Active Mobility Design
There are three important planning considerations for active mobility networks. It is vital to understand the rationale of the planned networks so that these fundamentals can be applied when designing active mobility infrastructure.
1.4.1
Safe
Safety is of paramount concern in planning for active mobility networks where commuters should always feel secure and at ease. Hence, sufficient space should be catered for safe manoeuvre.
Speed Limits and Rationale
Cycling on footpaths is allowed up to 10km/h* while cycling on cycling path and shared path is allowed up to 25km/h. The prescribed speed limit of 10km/h is to highlight that cyclists and PMD users should exercise due care and consideration for other users by not travelling too fast relative to pedestrians whom they share the paths with.
The speed limits are determined based on overseas standards (e.g. USA, Canada, etc.) to ensure the safety of the pedestrians while sharing path with the cyclists.
1.4.2
Direct
Direct routes promote accessibility, and save time and commuting distance for pedestrians and cyclists.
In terms of alignment and orientation, ideal active mobility networks should always strive to provide most straightforward routes to promote active mobility as a viable commuting mode.
1.4.3
Comfortable
Comfort refers to the quality of the active mobility commuting experience. Unlike private and public transportation, there are more opportunities to incorporate interesting and interactive elements into active mobility environments. Should planning succeed in creating comfortable, high-quality active mobility environments, it can motivate commuters to switch to active mobility. Design should also take care of users' needs e.g. ease of use, weather protection, intuitiveness, etc.
1.5
Walking and Cycling Network Principles
Considering the needs of different users, a set of principles is developed to guide the planning of active mobility networks.
These principles should be adhered to as far as possible. In the case where deviation from a particular principle is required, it should be done so in the pursuit of an alternative planning principle.
Besides commuting, walking and cycling infrastructure are also designed and built for recreational purposes. For example, recreation is the main drive behind our Park Connector Network (PCN). This is formed by creating regional loops and links that permeate across the island and follow the character of the region. The plan is to construct an islandwide network of linear green corridors that links up major parks and nature sites in Singapore, providing additional recreational areas for activities such as walking, jogging, cycling, and in-line skating.
The table on the following page illustrates the relationships between active mobility planning principles and design fundamentals.

Universal Design Principles in Active Mobility Designs
As Singapore prepares for a fast ageing population and builds an inclusive society, adopting Universal Design concepts will benefit a wider spectrum of people including Persons with Disabilities (PwD), parents with infants, the young and older persons. It is also important to make our urban infrastructure, including pedestrian footpaths, more senior friendly, catering to the growing population of older persons with limited mobility or mobility aids.
The figure on the right is an illustration from BCA's Code of Accessibility 2013, demonstrating the comfortable walking widths of various users. Walkways with adequate widths for comfortable gaits should be catered for persons using walking aids. This is because the crutch or cane tips often extend down at a wide angle, and pose as an obstacle to other pedestrians who may not notice them.

Active Mobility Programmes
1.7.1
National Cycling Plan
The National Cycling Plan aims to build on the existing and planned cycling paths and Park Connectors to develop cycling routes for recreational and commuting purposes, which will be integrated into a comprehensive network throughout Singapore.
Under the National Cycling Plan, 700km of dedicated cycling network will be implemented islandwide by 2030, with cycling networks in all HDB towns. These cycling paths will connect cyclists and PMD users from their homes to major transport hubs and key amenities such as food centres, schools, supermarkets and community centres within the town, promoting active mobility as a convenient and attractive mode of transport.
ABOVE: Islandwide intra-town cycling town routes (Updated as of Nov 2018)
1.7.2
Covered Linkway Programme
The Land Transport Authority (LTA) started building covered linkways in 2000 to enhance pedestrians' experience by providing sheltered walkway network between transport nodes and various amenities. They are currently built based on the following guidelines:
Between MRT stations and trip-generating hubs such as schools, healthcare facilities, public amenities, and commercial and residential developments within a 400m radius of the stations; and
Between bus interchanges/ LRT stations and developments within a 200m radius.
ABOVE: Covered linkway connecting to a bus stop

ROADSIDE ELEMENTS
Roadside elements refer to those within the roadside table, which facilitate the movement of people along the road. They form the key urban design elements to make the public streetscape friendly, vibrant and attractive. They are typically located within the road reserve that indicates the extent of the existing or future road and its related facilities such as footpaths, cycling paths, busbays, covered linkways and other commuter facilities.
Below are the key roadside elements that promote active mobility. They are provided along almost all road carriageway except expressways and semi-expressways.
2.1
Footpath
Footpath is a vital roadside element as it facilitates pedestrian movement and enhances overall connectivity. Accessible, safe, comfortable and well-maintained footpaths enhance walking experience and promote walking as a mode of transport for short-distance commuting.
2.1.1
Standalone Footpath
With Singapore's ageing population, the use of Personal Mobility Aids (PMAs), (e.g. wheelchairs, mobility scooters, etc.) is becoming more prevalent. New footpaths have been increased from 1.5m to 1.8m, which is the adequate width for two typical wheelchairs to pass each another (see Chapter 1.6 for details).
However, where there are observed or projected high pedestrian volume, footpath widths of more than 1.8m would be considered.
ABOVE: Design considerations for 1.8m standalone footpath
2.1.2
Footpath Next To Cycling Path
Cycling paths adjacent to footpaths may be used to negotiate manoeuvring space required by pedestrians, including wheelchair users. Under such circumstances, 1.5m is adopted as the dedicated pedestrian width.
ABOVE: Dimension of footpath is 1.5m when sited next to a cycling path
2.1.3
Materials
Concrete is used as the material for footpaths because of its skid resistant property (BPN ≥ 45) and durability. Good levelling and workmanship of floor finishes should be ensured to avoid undulation and protrusions that may result in trips and falls.
Regular maintenance and renewal of footpaths and pavement surfaces is important to ensure a non-slip and level surface.
ABOVE: Typical roadside footpath made with concrete
2.1.4
Features For Pedestrians with Vision Impairment
1 - Tactile tiles and kerb ramps are provided at areas near crossings to remind pedestrians, especially pedestrians with vision impairment, to be vigilant while crossing the road.
ABOVE: Placement of tactile tiles at crossingABOVE: Tactile tile
2.2
Cycling Path
For safety, cycling paths are designed to be separated from vehicular traffic on a different level. These paths are designed to separate the pedestrians and cyclists to minimise conflict. Finding sufficient space to cater for cycling paths is a challenge in the land-constrained Singapore. Thus, land owners and agencies need to work together to agree on the desired outcome and tradeoffs.
ABOVE: Terra cotta cycling path
2.2.1
Intra-town Cycling Path
Intra-town cycling paths facilitate short utilitarian distance trips within the town, and connect cyclists to the major public transport nodes (e.g. MRT, bus interchange). To improve the first- and last-mile connectivity, commuters are encouraged to cycle as a commute option to save time.
To keep the character of the Central Area, its cycling path will adopt a less intrusive demarcation while still using similar colour as those in outside Central Area. Two solid red or yellow lines will be used on the existing pavement to demarcate the cycling path. This treatment may also be applied to Business Parks.
ABOVE: 2m solid red cycling path in Central Area (to trial out)
2.2.3
Inter-town Cycling Path
Inter-town routes facilitate commuting, recreational and longer distance trips to connect people between towns, as well as to the city.
They are designed for seamless travel with minimal stops and detours, which will optimise cycling over longdistance commutes.
The Park Connector Network (PCN) forms the linear open spaces and links up major parks and nature sites in Singapore, providing additional recreational areas for activities such as walking, jogging, cycling and in-line skating. The intention is to create and evolve a network of park connector loops across the whole island to make it convenient for residents to travel from park to park or start their recreational activities close to homes or where they work.
They have evolved throughout the years and the PCNs are becoming part of the commuting network between homes to transport nodes too.
PCNs are usually built within both road and drainage reserves with a 4-metre wide track where space allows for distinctive planting schemes and provisions of advanced play and fitness equipment, shelters, seats and toilets to fit the needs of the people. The paths are made of continuous black asphalt, with markings to identify it as a Park Connector.
ABOVE: Park Connectors: tracks with typically 2.5m catered for cycling, 1.5m for walking & jogging
2.2.5
Cycling Path Features
Pedestrian Priority Zone (PPZ)
Pedestrian Priority Zone (PPZ) is a special zone applied in areas with high potential of conflict between pedestrians and cyclists. It is commonly implemented along the cycling path behind bus stops to inform cyclists that they have to give way to the pedestrians at and near bus stops. PPZ will also be implemented at the waiting area of pedestrian crossings, MRT entrances, Pick-up Drop-Off points, etc.
1 - PPZ
At PPZ, cyclists will become more alert and slow down to walking speed
2 - Speed Reduction Strips
Cycling Logo
The cycling logo is used as a visual cue to identify a cycling path.
The cyclist in the cycling logo is designed upright as speeding is not encouraged and cyclists should be gracious to other users.
ABOVE: Typical cycling logo on cycling pathsRIGHT: Cycling logo implemented on ground
Speed Regulating Strip
Speed regulating strips are applied at interaction zone to to regulate cyclists' speed for the safety of themselves and others. It also provide cyclists with visual and/or physical cues to prompt them to slow down and watch out for other users.
3mm strip
3mm thick strips are selected as they can adequately slow down and inform cyclists about the potential conflict/ danger ahead of them.
Thicker strips will reduce the contact between the bicycle wheel and path surface, which may cause cyclists on road bikes to skid. It is also a tripping hazard to pedestrians.
'Look' Marking
This marking is placed at locations with high pedestrian flow going across the cycling path. This marking is to inform pedestrians to look out for oncoming cyclists.
The marking is in yellow and against a black background to increase its prominence to pedestrians.
'Slow' marking
This is placed along cycling paths to inform cyclists to slow down.
Gradient of 1:25
According to AASHTO*, gradient of 1:25 is the comfortable gradient for cyclist to cycle over long distance.
* American Association of State Highway and Transportation Officials (AASHTO)
Material/ Surfaces
Coloured High Strength Coating System
-Skid Resistance ≥ 45 BPN
-Durable (resistant to wear and tear).
Brown Red Path (Colour code: RAL 3011)
- Red colour is applied to the cycling path to increase its visibility and reinforce the priority of the users on the footpath and cycling path.
Note: This does not apply to Park Connector Network (PCN) and Round Island Route (RIR).
Given the climate of Singapore, weather protection is an important factor for consideration in the design of our infrastructure. Covered linkways are shelters over footpaths to shield pedestrians from the weather while travelling from one place to another.
According to studies, weather protection is often one of the most important factors that affects people's decision to walk. Hence, to promote active mobility, the implementation of covered linkways at key locations is important.
2.3.1
Standard Covered Linkway
Height & Width
The height and width ratio of the covered linkway is designed to provide protection to pedestrians and cyclists from light rain and direct sunlight.
Its height also takes into consideration cyclists using the covered linkway:
- 95th percentile of Singaporean height is 1.83 m
- Diameter of bicycle wheel is 0.66 m
- Pedal is in-line with the centre of the bicycle wheel
To harmonise with LTA's covered linkway design, HDB has streamlined the designs of the covered linkway in the public housing estates to two simple designs. The design of covered linkway is intended to blend in with the environment, and achieve aesthetic harmony between precincts. Designs could be guided but not be limited to the illustrations shown in this Guide. HDB is open to creative ideas and solutions.
Design Principles:
Shallow Roof Profile & Neutral Colour
To allow the buildings and surrounding landscape to take centre stage, the use of a shallow roof profile and neutral colour (i.e. light grey/ mid grey/ off-white) is recommended.
Columns on One Side & Lightweight Roofing and Structures
For a more porous walking experience, columns are to be only on one side of the covered linkways, and lightweight roofing and structures are to be used.
2.3.3
High Covered Linkway
High covered linkways are provided across minor roads and vehicular accesses to link low covered linkways on both sides to facilitate weather protection for pedestrians/ cyclists.
The height of the high covered linkways is designed to allow vehicles to pass through. With such height, the shelters need to be wider to shield pedestrians/ cyclists from the weather as much as possible.
High covered linkways are provided with drop panels at the interface with the low covered linkways to minimise rain from splashing onto the footpaths.
ABOVE: High covered linkway over a local access road
2.3.4
Rest Areas Along Covered Linkways
To enhance the walking experience of the elderly and wheelchair users, covered linkways are complemented with rest areas at recommended intervals of 70- 100m*, subject to site context. Such rest areas comprise a bench and wheelchair parking space. To maintain a clear passage for the footpath, the rest area is set in an alcove.
The following should be considered when planning for rest areas along covered linkways.
Whether there are already other seating provisions in the vicinity;
Keep a safe distance from traffic junctions and carriageways; and
Allow sufficient buffer from adjacent developments to avoid potential disturbances.
2.3.5
Sheltered Pedestrian Waiting Area
Covered linkways provided at the waiting areas of the pedestrian crossings are called sheltered pedestrian waiting areas. The sheltered pedestrian waiting area is designed to provide enough coverage area to protect the pedestrians from light rain and direct sunlight while waiting to cross the road.
* Currently, BCA's Code on Accessibility in the Built Environment stipulates rest area to be implemented at every 50m interval. Rest area spacing along covered linkways and Round Island Routes (RIR) will be assessed case-by-case.
2.3.6
Common Features of Covered Linkway, Bus Stop & Taxi Stand
Structure
Cantilevered roof with columns sited away from the carriageway is the preferred design as it provides more circulation space for commuters.
ABOVE: Recently implemented covered linkway with cantilevered roofABOVE: Cantilevered roof with column sited nearer to developments
Interfacing
Panels are used to connect the shelter with adjacent structures to minimise rain splashing onto the footpath.
Lighting
LED lightings are provided. The lights and lighting fixtures are encased within the roof rafters to minimise any damage.
The lux level of lighting shall not be glaring, affecting the vision of motorists.
Light-weight honey comb aluminium roof panels are used. Columns are applied with anti-stick paint for ease of maintenance.
2.4
Covered Walkway
Covered walkways are sheltered paths within developments. They share a similar purpose as covered linkways. They are commonly found in Central Area and more are being implemented in regional centres and business parks (e.g. Woodlands Regional Centre).
2.5
Roadside Verge
Our city is made up of extensive roadside greenery that forms the backbone of our City in a Garden. It is important to ensure that sufficient roadside verge is provided for tree planting to sustain the pervasive sense of greenery, which is a distinct characteristic of Singapore. A tree-lined street will also provide for a more pleasant environment for pedestrians and cyclists.
Roadside verge consists of the tree planting and service verges. Their dimensions shall be in accordance with LTA's Code of Practice for Works on Public Streets. The requirements for the roadside verge are highlighted in the table below. The planting scheme along the roadside depends on the existing site condition and landscaping theme for the area.
* Planting verge and Service verge shall be in accordance with LTA's Code of Practice for Works on Public Streets.
Requirements For Roadside Verge
Soil
Turf
Gradient of Slope
Minimum 2.0m soil depth
-Top layer 1.0 depth of Approved soil mixture (ASM) for the planting verge
-Bottom layer (1.0m depth soil)
There should not be any hardcore or construction debris within the backfill soil/material for the roadside verge.
50mm thick Axonopus compressus (cow grass) in close turfing
Generally to be (1:40). The finished soil level of the verge is to be 25mm below footpath.
Please refer to NParks' Guidelines on Greenery Provision and Tree Conservation for Developments for more detailed specifications for roadside verge, soil and planting.
2.5.1
Tree Planting Verge
This is the portion of the roadside verge tree planting. Its typical width is 2m. There should be no encumbrances (e.g. underground services) within the tree planting verge so as not to stymie tree planting. Services that are required to transverse through a tree planting verge into an adjacent building plot are to be laid at least 2.0m below ground level, where possible, and away from any existing roadside tree.
2.5.2
Service Verge
This is the portion of the roadside verge that is allocated for the laying of underground services (e.g. water and gas pipes). Its width may vary depending on the road reserve width.
2.6
Green Buffer
Green buffer is the planting area within and along the boundary of premises adjoining a public road. It is not part of the road reserve. When planted up lushly with trees and shrubs, it serves as a buffer between the development and the road, and contributes to a more pleasant environment. The green buffer is also important in augmenting the roadside greenery, which is a key element of our City in a Garden.
Green buffer is required along the sides of the development boundaries that front a public road. Its width is to be provided in accordance with the road category. The classification of the road category is available from the Land Transport Authority (LTA) through the purchase of the Road Interpretation Plan.
2.7
Roadside Drain
Drainage can be an important element to enhance commuters' walking and cycling experience. Roadside drain refers to drains within road reserve. The capacity of the drain is determined using the Manning's Formula which is dependent on factors such as the size (width and depth), geometry (channel shape or rectangular) or bed gradient.
In the past, roadside drains are generally designed as open drains (composite channel drain/ U drain) beside the footpath to maintain visual connection with water and to facilitate maintenance. Today, with the increasing land scarcity, land is being optimized by reconstructing the open drains into box drain for the top of the drains to be used as footpath and/or cycling paths.
Roadside drains typically range from 0.6m-1.2m in width. In some cases, they can be wider due to the catchment served by the drain. For these cases, appropriate drainage reserves (DR) shall be set aside for these drains in accordance to the current edition of Code of Practice on Surface Water Drainage. DR/s required for drains sited along roadside that cannot be accommodated fully within the road reserve shall be secured for the drains.
ABOVE: Open Composite channel drain beside footpathABOVE: Roadside drain reconstructed as box drain which doubled up as footpath
*The details of the drain shall apply to drains outside road reserve.
2.7.1
Types of Roadside Drain
Below are the various types of roadside drains*. For closed drains, the proposed footpath, cycling path or covered linkway sited on top of the drain is provided with an effective drainage system to intercept and discharge the surface water runoff. Effective drainage is especially important in areas where path level is lower than existing surrounding grounds (e.g. steep slope adjacent to path or footpath lower than adjacent verge). Runoff from all the paths shall be effectively drained away without causing flooding problem on top of the paths and the adjacent areas.
Appropriate gratings are provided on the footpath at regular intervals to facilitate inspection and maintenance. The drain gratings are designed to ensure safety of the pedestrians from tripping and to provide effective drainage to minimise flooding on the footpaths, cycling paths and adjacent areas. The drain gratings shall be implemented in accordance to LTA's Stand Details of Road Elements.
* Some roadside drains are not entirely within the road reserve.
2.8
Bus Stop
A bus stop is a designated place where buses stop for passengers to board or alight from the bus. It consists of a few of the following components.
Bus Shelter - A covered structure sheltering commuters from the weather and almost always comes with seats. Footpath, covered linkway and cycling path should be aligned behind the bus stop, where possible.
Bus Bay - A dedicated bus stopping zone off the main road. Where there is limited space for off road bus stopping zones, a yellow rectangle box is painted on the road to mark the designated bus stopping area.
Bus Pole - A metal pole erected beside the bus stop, which shows the bus routes that call at the particular stop. These poles often come with small notice boards which provide bus timings (usually for services with limited frequency), diversion notices, or other relevant bus service updates.
Information Panel - An encased information board with service information. It is regularly updated by LTA with new routes or changes to existing information.
Safety Bollards - Bollards are steel and concrete structures which reduce the severity of impact due to collision by errant motorists and are painted in grey with a retro reflective yellow sheet and printed with black arrows on the upper portion. Safety bollards are provided at all bus stops for the safety of commuters. Refer to LTA's Standard Details of Road Elements for more details.
2.8.1
Typical Bus Shelter
Height and Width
The width of the shelter is designed to accommodate seating space, circulation space for a wheelchair user and standing space for commuters.
The height of the shelter is designed to protect pedestrians from the light rain and direct sunlight.
Bus shelters are sized and built based on its commuter's usage / boarding counts.
Bus stops are designed to be barrier free for commuters. Hence, steps are not permitted at the alighting and boarding area of the bus stop.
To shield commuters from light rain and direct sunlight during boarding and alighting from buses, high bus shelter roofs are preferred for bus stops with bus bays near MRT stations, considering the high commuter volume at such bus stops.
The high roofs over the bus bays are provided with height clearance for buses to pass through. More detailed requirements can be found in LTA's Architectural Design Criteria.
Either a drop panel or a second roof is provided at the commuter waiting area to screen commuters from rain splashes. For the ease of maintenance, as mentioned in LTA's Architectural Design Criteria, glass and other materials shall not be used for structural and architectural finishes.
2.8.3
Bus Stop Features
Bench
Benches are provided at every bus stop and some benches are fitted with armrests to aid the elderly.
Benches are designed to prevent water stagnation.
Weather screens are provided behind benches where acces - sibility and circulation are not compromised.
2.9
Taxi Stand
A roadside taxi stand is a designated area for taxis to pick up waiting passengers. It consists of components similar to bus stops such as a taxi stand shelter, taxi bay, taxi identity signs and notice boards. For developments' taxi stands, we recommend to integrate them with the development itself.
Height and width
The width of the shelter is designed to accommodate seating space for commuters and circulation space for a wheelchair user.
The height of the shelter is designed to protect commuters from the light rain and direct sunlight.
Ramps and tactile tiles are provided to aid barrier-free access to board and alight the taxi.
High roof taxi/ passenger pick-up/ drop-off shelter
For taxi stands near MRT entrances, high roofs over the bays with the appropriate height clearances and widths necessary to shield commuters from the light rain and direct sunlight when alighting and boarding are provided. More detailed requirements can be found in LTA's Architectural Design Criteria.
2.10
Lighting
For paths along the roadside, there is a need to ensure adequate street lighting for the safe passage of all users. Adequate lighting is necessary for users (e.g. pedestrians, cyclists, motorists, etc.) to identify and react to the following situations:
Alignment of the paths;
Sharp bends, humps and fixed obstacles;
Objects on the surface such as stones, tree branches;
Potholes or cracks in the surface;
Position and speed of other users;
Junctions carrying other users.
2.10.1
General Lighting Illuminance
Illuminance Level: As a guide, the designed lighting levels for the different categories of road for new Street Lighting are as shown below.

Placement of Lamp Post for Active Mobility
As a principle, lamp posts are placed along the planting verge between trees to avoid the tree roots.
We may explore siting them in other locations when under land constraints, subject to case-by-case assessment.
ABOVE: Lamp post placed along planting verge, at tree interval
2.10.3
Design of Street Lighting
The design of street lighting for public roads shall comply with but not limited to the latest edition of BS 5489, BS EN 13201, CIE (International Commission on Illumination) and the relevant authorities' codes, regulations and standards.
For the purpose of design, road surface shall be taken as Class R3 road (Asphalt CIE R3). Lighting design should be carried out with a recognised lighting design software (e.g. Calculux, Dialux, etc.) that is commonly provided by the lighting supplier.
For LTA's detailed technical requirements, drawings and guidelines on the submission of design drawings for public street lighting, footpath lighting, cycling path lighting and zebra crossing flashing beacon lighting system, please refer to LTA's Public Street Lighting Guidelines.
2.10.4
Cycling Path Lighting Design
Design Details
Design Rationale
Height
3.5m pole shall be used for dedicated cycling path lighting design.
Light sources
Use LED lighting technology.
Interfacing lamp post with vegetation
Work closely with NParks to ensure that the placement of vegetation and
type of vegetation will not obstruct lighting throw from the lamp posts.
Placement of lamp post near residential area
At or near residential areas, lamp posts are positioned such that they do not
cause glare or shine into residences. If necessary, add on louvers or shields to
block out lighting throw into nearby residences.
Maintenance of lighting
Use a standard type of lighting design so that the implementation, maintenance
and replacement works are cost effective. For tourism districts, decorative lightings
can be used after careful consideration of overall costs to ensure prudent use of public funds.
ABOVE: Lamp post along cycling path
2.10.5
Cycling Path Lighting Within Covered Linkway
Where a cycling path runs next to a covered linkway, we recommend the lighting to be shared between the cycling path and the covered linkway to minimise land required for dedicated lamp posts for the cycling path.
Design Details
Design Rationale
Height
In this case for cycling paths, it is recommended to place lightings at least
at a height of 2.4m* so that the lighting throw is downwards onto the path,
and will not cause glare to the users. This is to ensure that the lighting fixtures
will meet the international standards for glare ratings.
*2.4m height may vary, depending on the actual height of the covered linkway.

ROADSIDE TYPOLOGIES
3.1
Standard Typologies
The placement of cycling path and footpath are according to the gradation of speed, with the former closer to the carriageway and latter closer to developments.
The smooth gradation of speed (see the previous page) would ensure that pedestrians would meet the other pedestrians walking at similar speeds first when coming out of the adjacent developments. The footpath acts as a buffer to allow cyclists to have more time to react to users on the footpath.

Central Area Typologies
The Central Area has a different set of roadside typologies. This is because most buildings here are built next to the Road Reserve Line with the provision of a covered walkway along the 1st storey of developments next to an open footpath. These covered walkways, together with the adjacent open footpaths within Road Reserve, form part of the comprehensive pedestrian network planned for the City Centre and provide users with an all-weather route.
3.2.1
Covered Walkway & Footpath

3.2.2
Covered Walkway & Cycling Path
Where there is sufficient space and a cycling path is planned next to the covered walkway, a 2m wide dedicated cycling path is preferred.
ABOVE: Perspective of roadside with covered walkway and cycling path
3.2.3
Raised Covered Walkway & Lowered Shared Path
When the covered walkway is at a different level from the open footpath, the cycling path is to be a shared path with a minimum width of 2.5m.
ABOVE: Perspective of raised covered walkway and lowered shared path
3.2.4
Elements between Covered Walkway and Open Footpath
Scenario 1 - Where the covered walkway and open footpath are separated by planting, for example, the cycling path is to be a shared path with a minimum width of 2.5m.
ABOVE: Perspective of Scenario 1 involving covered walkway and shared path
3.2.5
Elements between Covered Walkway and Open Footpath
Scenario 2 - Where there are tree pits located between the open footpath and the covered walkway, a 2m-wide dedicated cycling path shall be provided closer to the side of the road carriageway.
ABOVE: Perspective of Scenario 2 involving covered walkway, open footpath and cycling path
3.2.6
Covered Walkway, Building Setback and Cycling Path (Marina Bay)
This typically applies to the Marina Bay area, where there is building setback for the developments.
ABOVE: Perspective of covered walkway within development, with building setback and cycling path
3.3
Park Connector Network (PCN) & Round Island Route (RIR) Typologies
The Park Connector Network (PCN) paths are typically made of continuous black asphalt. Standard PCN paths are 4m in width - 1.5m will be labelled as footpath and 2.5m as PCN. Should the path be less than 4m wide, its footpath portion will remain as 1.5m and PCN portion be reduced.
PCN follows two standard typologies dependent on the path width: 1) 4m segregated path and 2) shared path for those with less than 3.5m width.
3.3.1
Segregated PCN Path (4m width)
3.3.2
Shared Path (less than 3.5m width)
Where there is less than 3.5m space available, a shared path is preferred. The entire path will simply be labelled 'PCN'.
3.3.3
Harmonisation Between PCN and Cycling Path Network (CPN)
To harmonise with the Cycling Path Network (CPN), the footpath portion of PCN will be demarcated with a pedestrian logo. While the cyclist logo is used on CPN, the PCN imprint will be used along the PCN portion instead. PCN imprints will be spaced closer at 100m intervals.
3.3.4
PCN-RIR Corridor (6m width)
The Park Connector Network Round Island Route (PCN-RIR) beside road reserves will have a 6m path made up of a 2m footpath and 4m PCN path. The adjacent greenery is 4m in width, 2m of which will be the streetscape green buffer and the remaining as the service verge. On the other side of the path, no dedicaated planting will be provided. Any additional greenery will be borrowed from adjacent developments.
ABOVE: Perspective of PCN/RIR Corridor

NON-ROADSIDE TYPOLOGIES
4.1
Where Both Abutting Developments Are Non-Porous*
We recommend providing a dedicated planting verge for visual relief in view of the confined space and shade for users where both abutting developments are non-porous. Below are four scenarios under such a situation.
4.1.1
Footpath & Dedicated Planting Verge
* Developments are non-porous if they are bounded by boundary walls/ fencing, regardless of the materials used.
4.1.1a
Short Footpath With No Dedicated Planting Verge (Exception)
In low density areas or areas with low pedestrian flow, a standalone 2.5m footpath with path light ing and no dedicated planting verge may be considered. This can be applied in industrial and landed housing areas for a length of not more than 30m.
4.1.2
Footpath, Cycling Path & Dedicated Planting
4.1.3
Covered Linkway & Dedicated Planting
It is not recommended to implement covered linkway next to landed residential area due to security concerns, unless necessary depending on the site context. Wider covered linkway width (standard width: .4m) can be assessed based on site context (e.g. areas with high pedestian traffic).
* Developments are non-porous if they are bounded by boundary walls/ fencing, regardless of the materials used.
It is not recommended to implement covered linkway next to landed residential area due to security concerns, unless necessary depending on the site context. Wider covered linkway width (standard width: 2.4m) can be assessed based on site context (e.g. areas with high pedestian traffic).
*Developments are non-porous if they are bounded by boundary walls/ fencing, regardless of the materials used.
4.2
Where At Least One Abutting Development Is Porous*
Under this situation, greenery can be tapped from the peripheral planting from the development/s, hence planting verge may not be required. There are four scenarios under this situation.
4.2.1
Footpath With Peripheral Planting
This typology may not be applicable to footpaths within HDB precincts as HDB will integrate the necessary pedestrian connections as part of its precinct design.
* Developments are porous if they are not bounded by boundary walls/ fencing, regardless of the materials used.

Park Connector Network (PCN) & Round Island Route (RIR) Typologies
Similar to Chapter 3.3 for roadside typologies, non-roadside PCN paths are 4m in width where 1.5m will be labelled as footpath, and 1.5m as PCN. Should the track be less than 4m, the PCN portion will be reduced.
PCN follows two standard typologies dependent on the path width: 1) 4m segregated path and 2) shared path for those with less than 3.5m width. For the types of plantings to be planted along the waterway, please refer to the chapter on 'Waterway Planting' in Sustainable Landscapes, a publication by NParks' Centre of Urban Greenery & Ecology (CUGE), for more information.

PCN-RIR at Drainage Reserve
There are two typical typologies for PCN-RIR paths at Drainage Reserve (DR). For both scenar ios, 2m of borrowed greenery will be located opposite the canal but the m planting verge for the PCN can be either beside the canal or the borrowed green space. Coastal Areas will have a wider space allocated to the RIR to allow for larger planting space (9m). Boardwalks for RIR will be 5m in width.

CROSSING FEATURES
5.1
At Grade Crossings
5.1.1
Junction Crossing
Most of Singapore's signalised junctions are designed with pedestrian crossings to balance the needs of vehicular and pedestrian traffic on the roads. Typically, pedestrian crossings are pro vided on all sides of the junction unless there are site limitations, traffic or safety considerations.
Example of pedestrian cross ings implemented on all sides at a major junction.Example of a limited crossing leg at a T-junction due to traffic and safety considerations.
Overview: Major Junction With Wider Crossings For Cycling
5.1.2
Mid-block Crossing
Mid-block pedestrian crossings are usually implemented near developments and amenities that generate high volume of pedestrian activity. They can be designed as a one-stage or two-stage crossing depending on the road geometry, traffic volume and crossing span. One-stage design is perceived as more convenient for the pedestrians and cyclists. However, for wider roads with a wide centre divider, two-stage crossing is catered so that the walking distance can be split with a break in between. This helps to accommodate pedestrians with a slower walking pace without overly affecting the delay to vehicular traffic.
Example of a one-stage crossingExample of a staggered crossing
5.1.3
Design of Junction and Mid-block Pedestrian Crossing
Pedestrian crossings are minimally 3m wide. Wider crossings are considered at locations with high pedestrian traffic (e.g. near major transport node or amenities). Pedestrian crossing aspects with countdown timers and traffic signal aspects must be provided and not be obstructed to ensure clear visibility.
Pedestrian's waiting area is ramped down and provided with homogeneous tactile tiles for the visually-impaired. Pedestrian and cyclist crossing prohibition signs are provided 50m from the crossing to demarcate the jaywalking zone*.
*Jaywalking zone: Pedestrians are deemed jaywalking when crossing the road within 50m from a junction.
Pedestrian Crossing Lines are of dashed lines to make the designated crossing more conspicuous. At least 2 sets of arrow markings are provided on the road carriageway before the stop line to guide motorists to slow down as they approach the crossing.
ABOVE: Signalised pedestrian crossing
5.1.4
Zebra Crossing
Zebra crossings are usually implemented at minor roads and on slip roads where pedestrian and traffic volume is lower. Zebra crossings at slip roads are often demarcated with markings, flash ing beacons and signs. Alternatively, there are also raised zebra crossings which are elevated in nature and are flushed with the footpath for barrier-free access.
ABOVE: Zebra crossing at slip lane
5.1.5
Bicycle Crossing
Bicycle crossing is an additional feature to current mid-block pedestrian crossing. With the legali sation of cycling on footpath, all new mid-block crossings will have a bicycle crossing.
Design of Bicycle Crossing
A dedicated bicycle crossing is m in width, identical to the dimensions of a pedestrian crossing. Instead of homoge nous tactile tiles, a 'Look' box will be provided for cyclists at the bicycle crossing waiting area. At the bicycle crossing area, the traffic signal will also show a bicycle logo.
Pedestrian Overhead Bridge (POB) is typically built across at least Dual-Two road for safer cross ing of pedestrians. To provide barrier-free access (BFA), lifts are now installed at POBs. Also, cycling is not allowed on POB due to safety reasons. Please refer to LTA's Architectural Design Criteria for more detailed requirements on the following.
Structure
ABOVE: POB dimensions
A POB is an elevated structure across the road supporting a sheltered footpath. It is provided with sheltered staircases on both ends. The bridge is provided with a height clearance to allow vehicles to pass below the structure.
Typically, POBs that are intended to provide easy accessibility to the nearest transport nodes, such as bus stops, will have their staircases oriented towards the bus stops either in dog legged or straight arrangements to route pedestrians to the bus stops.
The typical clear width of the footpath on the structure is m and it is determined based on a space for two pedestrians to walk side by side and a third pedestrian to overtake. For bridges with heavier footfall, the widths will be increased accordingly.
Planter boxes are provided on both sides of the bridge as part of our effort to keep Singapore a city in the garden.
ABOVE: Straight leggedABOVE: Dog-legged
Staircase
ABOVE: Stairs leading to POB
The width of the staircases is determined based on similar considerations as the width of the footpath on the bridge.
The bridge including the staircases are provided with shelter to protect pedestrians from light rain and direct sunlight. Typi cally, the shelters are connected to the covered linkways. The details of the shelter are similar to those of covered linkway found in Chapter 2.3.
Lifts
ABOVE: A lift serving POB
To achieve barrier free accessibility, ramps have been provided and in more recent years, in areas where footfalls are heavier and comprise more elderly pedestrians, lifts have been provided instead.
Typically, if the bridge connects to cycling paths on both sides of the road and there is no pedestrian crossing at grade within a 200m radius of the bridge. The lifts, if provided, are sized to fit two bicycles in addition to pedestrians.
Bicycle wheeling ramps help cyclists traverse stairs or pedestrian overhead bridges along the cycling path network. They are implemented in locations where there is no barrier-free ramp or lift.
The recommended width of wheeling ramp varies between 200mm and 350mm. The recommended width of the wheeling channel is 100mm and constructed in appropriate distance from the railing/ secondary handrail to avoid the catching of pedals or handlebars. It is recommended to ensure a smooth transition onto and off the ramp.
The surface of the wheeling ramp is recommended to have an anti-slip finish of skid resistance within the range of 45 to 60 BPN to ensure sufficient grip on descend. Finishing colour is recom mended to be blue RAL5000 or equivalent. Surface water runoff through the wheeling channel should also be taken into consideration to prevent water ponding.
Position of Wheeling Ramp
Straight legged staircases: Recommend placing the wheeling ramp on the right (from bottom). As most cyclists are right-handed, it would be easier for them to push the bicycles up the straight legged staircase, which requires more effort as compared to going down.
Dog-legged staircases: Recommend placing it on the left (from bottom) since the constraint is the turning point at the inner part of the staircase is shorter as compared to outer part.
ABOVE: Example of wheeling rampStraight Staircase StructureDogged-leg Staircase Structure
5.2.2
Cycling Bridge
To provide the critical connectivity, cycling bridges are essential to overcome physical barriers, (e.g. canals, expressways and terrain differences). Unlike pedestrian overhead bridges that require cyclists to dismount and push their bicycles, cycling bridges provide seamless commuting for all users - cyclists, pedestrians, joggers, personal mobility device users and persons with disabili ties.
Location
Cycling elevated structures are vertically separated from motor vehicle traffic (e.g. ex pressways, roads, rail tracks) or water bodies (e.g. river, canals).
Proper treatment should be provided when the elevated structure merges onto the existing street.
ABOVE: Artist's impression of the future cycling bridge connecting Tampines and Pasir Ris across Tampines Expressway (TPE)
Clear Width
We recommend a minimum clear width of 4.8m for all elevated cycling structures - minimum 1.8m for pedestrian and 3m for cyclist lane with demarcation, and excluding space allocated for railing. The minimum clearance pro vides necessary manoeuvring space to minimise conflicts with/between pedestrians and cyclists.
A minimum of 1.8m pedestrian path is recommended to allow 2 wheelchair users to comfortably bypass each other. A minimum of 3.0m cycling path is recommended to cater for cyclists' lateral move ment to balance themselves when going up or down the ramp.
Headroom Clearance
1 -Headroom clearance is the distance measured from the base of structure to the surface of ground. The mini mum recommended head room clearance of the cycling elevated structure over expressway and road is 5.7m from the road surface. It also has to design for full collision load on super structures in accordance with the latest National Annex to Eurocode (2011).
Vertical Clearance
2 -Vertical clearance is the minimum vertical distance from the floor of the cycling bridge to the overhead structures. Taking into consideration the average height of a cyclist and diameter of a bicycle wheel, its recommended minimum vertical clearance is 2.4m to prevent cyclists' collision with overhead fixtures.
Bridge Ramp
According to international standards, the access ramp of the bridge is recommended to have a minimum 4.8m clear width. For ease of cycling up the ramp, its recommended gradient is or gentler than 1:25 (4%). A gradient break in every 100m ramp, with a level landing of minimally 5m is recommended to allow at least two bicycles to rest abreast of one another.
3 - Level landing of minimally 5m every 100m ramp.
Bridge Railing Height
All railings are recommended to be 1.4m high(minimum 1.2m) and use stainless steel Grade 316 with a minimum buffer of 150mm pedal clearance at the bottom of the railing.
A continuous handrail shall also be provided along the staircase and ramp at 0.9m high from the thread and ramp.
ABOVE: Ulu Pandan Cycling Bridge (Photo Credit: Darric Tan)
Drainage & Lighting
Drainage system shall be designed such that surface runoff is properly discharged to drains to prevent water ponding. Effective drainage shall continue to be provided for the area around and in the vicinity of these crossings.
Please also refer to Chapter 2.10 and LTA's Public Street Lighting Guidelines for the cycling path lighting requirements and technical specifications.
Other Additional Requirements
Planting Troughs
Providing continuous planting troughs on both sides of the cycling bridge along the por tions that cross over roads is recommended.
Please consult NParks for more details.
Safety
Measures such as calming devices (e.g. speed regulat ing strips, humps), curve widening, signage and stop ping sight distance should be considered in the design to address potential safety issues.
To direct users to their desti nations, wayfinding signage should be provided near decision points with multiple access or exit points, or when access points are difficult to locate.
5.3
Traffic Calming Measures
Traffic calming measures are implemented at suitable locations to manage motorists' speed. More measures are implemented at Silver Zones and School Zones to enhance the safety and walking experience for senior pedestrians and students.
5.3.1
Physical Measures

Road Hump
Road humps slow down vehicles
and prevent motorists from speeding.
Bus-friendly Hump
Normal road humps, or roundtop humps are unsuitable for buses, as they can cause
discomfort or even injuries to standing passengers.
Hence, bus-friendly humps are placed along bus routes where such speed calming devices are needed.
Speed Regulating Strips
Speed regulating strips are used to slow down vehicles at locations where it is not advisable to travel at high speed.
Road Divider
Road dividers narrow lane widths, to encourage vehicles to travel slower.
5.3.2
Perceptual Measures

Road Marking
The 'SLOW' markings are to inform motorists to reduce their speed due to the proximity of some danger ahead.
Chevron Marking
Chevron markings visually narrow lane (at roads that are not advisable to be constructed with physical centre divider), to encourage vehicles to travel slower.
Your Speed Sign (YSS)
'Your Speed Sign' is a live electronic device that displays the real time speed of vehicles and alerts motorists that they are speeding. It encourages motorists to obey the speed limit displayed and thus improve safety on the roads.
YSS is now part of LTA's range of measures used to improve the safety of roads along selected expressway slip roads.

Silver Zone
Silver Zones are areas with enhanced road safety meas ures, such as new signs, road features and markings, to change the character of the street, making it safer and more convenient for senior pedestrians. This is achieved by narrowing roads to lower vehicle speeds, reducing speed limits, guid ing pedestrians to specific crossing points. Silver Zones are found in selected hous ing estates with high senior populations, relatively higher accident rates involving seniors and closer proximity to amenities catering to the seniors.
ABOVE: Silver Zone implemented on ground
Silver Zone Gateway
The Silver Zone Gateway includes signs and road markings that indicate the start of a Silver Zone. These features have attention-grabbing bright fluorescent yellow-green signs and yellow rumble strips. They aim to alert motorists to slow down and look out for senior pedestrians. Silver Zones will also reduce speed limit to 40km/h, where possible.
Setback Crossing
Setback kerb cut ramps allow pedestrians to enjoy shorter crossing distances. Motorists also benefit by having sufficient time to look out for potential crossing pedestrians. At kerb cut ramps, motorists still have the right of way and pedestrians should ensure that there are no oncoming vehicles before crossing the road.
ABOVE: Junction of Bukit Merah View and Jalan Bukit MerahABOVE: Silver Zone Gateway and Setback Kerb Cut Ramps at junction of Bukit Merah View and Jalan Bukit Merah
Two-Stage Crossings
Pinch Points and Eye-Lands provide pedestrians with two-stage crossing so that they can rest momentarily at the pedestrian refuge (centre divider) before continuing to cross the road. Kerb cut ramps eliminate the need to step up and down roadside kerbs so it is easier on the legs. Tactile tiles are provided on the ramps to serve as a reminder to look out for vehicles before crossing the road.
Pinch Point involves pinching of the lane widths so as to encourage motorists to slow down.

Eye-Lands bulge out of the carriageway, creating a widened centre divider as a refuge for crossing pedestrians.
Before: Straight stretch of road at Bukit Merah ViewAfter: Eye-Land at Bukit Merah View
Chicane
Chicanes are horizontal curves constructed along existing straight stretches of roads. They create S-shaped curves that encourage motorists to drive slowly.
Before: Straight stretch of the road at Bukit Merah ViewAfter: Chicane at Bukit Merah View
Mountable Centre Divider
Mountable Centre Dividers, being low in height, allow emergency vehicles to pass over them dur ing emergencies when is it safe to do so. They also aim to narrow lane widths so vehicles travel slower, making it safer for pedestrians to cross the road.
Before: Undivided road configuration at Jurong West Street 52After: Mountable Centre Divider along Jurong West Street 52
Bollards at Crossing
Bollards fitted with retro-re flective sheeting are installed at zebra crossings. When headlights of approaching vehicles shine onto them, the sheeting reflects the light back to the motorist. This makes the crossing more obvious.
Bus-friendly Hump
Bus-friendly humps slow vehicles down and prevent motorists from speeding. Commuters will have less discomfort when the bus travels over a bus-friendly hump as compared to the road hump.
Before: Undivided road configuration at Jurong West Street 52After: Bus-friendly Hump implemented along with centre divider at Jurong West Street 52
5.3.4
School Zone
During the start and end times of school sessions, there is usually heavy traffic near schools. As children are inexperienced and vulnerable road users, it is important to keep school zones safe.
Prominent school zone signs are installed at school zones to inform motorists that they are enter ing a school zone and should drive carefully.
Traffic safety measures
Other traffic measures may be installed in school zones to enhance safety, including:
- Traffic calming measures such as road humps and speed regulating strips
- Raised road surface at pedestrian crossing/signalised at grade crossing
- Parking restrictions
- Railings along the road centre to deter jaywalking
Enhanced School Zones
A school zone with more vis ible features gets the atten tion of motorists and reminds them to drive more carefully.
The Enhanced School Zone scheme was introduced to in crease the visibility of school zones through the following ways:
- Prominent school zone signs to indicate the start and end of school zones;
- Parts of the road surface near the school gate are covered with a red texture to catch drivers' attention and alert them to look out for children crossing the road;
- 'SLOW' and 'SCHOOL' word markings on the road to further remind motorists that they are travelling within a school zone.
The Enhanced School Zone is implemented at primary schools and special schools, subject to factors such as the road geometry and the type of road outside the schools.

BIKE PARKING & SUPPORTING FACILITIES
6.1
Bike Parking Design
With an increasing demand in cycling, it is challenging to provide sufficient bicycle parking lots in our land-con strained Singapore. Hence, a variety of bicycle parking designs is adopted to opti mise space, such as U-Bar racks and double tiered racks, amongst others.
ABOVE: Double-tiered bike racks at Ang Mo Kio MRT
To provide secured bike parking facilities, all racks should ideally allow users to lock a bicyle at 3 points: the front wheel, frame, and back wheel.
Water ponding on the facilities is to be taken into considera tion as ponding will promote mosquito breeding.
ABOVE: Bike racks should provide 3 points for secured bike parking
6.1.1
Wheel Rack
Wheel racks are basic racks where the front wheel of the bicycle slots in the gap and is chained to the rack.
Wheel racks are usually spaced 0.6m away from each other and can accommodate 1 bicycle per rack.
Pros
Cons
Cost-efficient and require minimal clearance width
Only the front wheel of the bicy cle can be chained. Users do not have the option
to secure other parts of their bicycle.
6.1.2
U-bar Rack
U-bar racks, or Sheffield racks, are shaped in an inverted U anchored on the ground. Cyclists can rest their bicycle on the structure and chain it to any part of the rack.
U-bar racks are spaced 0.6m away from each other and can accommodate 2 bicycles per rack.
Spatial comparison between U-bar and Double-tiered racks
6.1.3
Double-tiered Rack
ABOVE: At Ang Mo Kio MRTABOVE: At Tan Kah Kee MRT
Double tiered racks have a second elevated tier to accommodate another bicycle.
Racks are usually spaced around 0.65m apart and can accommodate 2 bicycles per rack.
Pros
Cons
Space efficient: effectively doubles the density of a given space.
More expensive than wheel racks and U-bar racks. Some users may have difficulty when hoisting the bicycle up the upper level.
How To Use The Dual Bicycle Rack System
6.1.4
Designated Bike Parking Zone (Yellow Boxes)
Bike parking zone demar cated with a yellow box is a designated bike-parking zone for all cyclists' use. With the popularity of the bicycle shar ing scheme in Singapore, this designated bike-parking zone has been introduced to more locations islandwide as one of the measures to address indiscriminate parking of bike share bicycles.
Currently, the scheme is im plemented at locations such as MRT stations, bus stops, void decks and parks. LTA is working closely with agen cies like Town Councils & NParks, as well as bike-share operators to draw more boxes within their respective man aged areas islandwide.

6.1.5
Automated Mechanised Underground Bicycle Parking System
ABOVE: Conceptual design of the Automated Mechanised Underground Bicycle Parking System
Automated Mechanised Underground Bicycle Parking System allows cyclists to store bicycles and cycling gear securely, and protect their bicycles from theft, vandalism, and the weather.
'SecureMyBike' is Singapore's first fully automated underground bicycle parking system. Originating from Spain, this bicycle parking facility can store up to 501 bicycles and will pilot in Kam pung Admiralty development.
Bike parking slot (closed) & Bike parking slot (open)
Pros
Cons
Efficient for areas with land constraints to utilise space under ground to store bicycles, freeing up more valuable above ground space. The mechanised system allows bicycles to be stacked closer together as well, increas ing the density.
Expensive to construct and maintain.
6.1.6
Other Bike Parking Designs
There are different bike parking designs implemented in Singapore and else where, which can make the streetscape more lively and interesting.
New and innovative designs are welcomed as long as they cater to the bike parking needs in the area and fit the site context.

6.2
Bike Parking Provision
Provision of bicycle parking within developments is one key strategy to encourage people to com mute via cycling. We have established the minimum bicycle parking provisions for the different types of development (i.e. MRT stations, parks, HDB development, etc.) below.
6.2.1
MRT Stations
Station Class
Range of Bicycle Parking Lot provisions
Remarks
First-mile Station
250 to 800
Aditional 80 lots per foreign workers dormitory within 1.5km from the MRT station
Last-mile Station
130 to 180
- Additional 50 lots per foreign workers dormitory within 1.5km from the MRT station
- Deduction of 80 lots if the station has a bus interchange/Integrated Transport Hub (ITH)
Depending on the nearby landuse, MRT stations are catego rised as either a predominantly 'first-mile' or 'last-mile' station. Subsequently, the number of the bicycle parking lots is deter mined based on various factors such as MRT ridership, dwelling units (DUs), and presence of foreign workers dormitory. Based on existing data and surveys, the 'first-mile' stations have higher bicycle parking lots demand as compared to last-mile stations, hence the higher quantum required.
ABOVE: Bike racks along Bencoolen Street
6.2.2
Private Developments
To promote car-lite, the Walking and Cycling Plan (WCP) aims to guide developers to implement active mobility related infra structure. Under the WCP, developers will provide bicycle park ing facilities to encourage active mode of transport.

Short-term bicycle parking spaces cater to visitors. Hence, they should be located at the ground level for easy access by the public. Similarly, long-term parking spaces cater to tenants or resi dents and could be located at any level of the development with safe internal cycling circulation leading to the facilities. The recommended short-term and long-term bicycle parking ratio is listed in Table 2 below.
