Complete Guide to Waze in Singapore (Under Development)
Thank you for your interest in helping improve Waze in Singapore. We should all aim to have the Best Mapping Solution. Editing is a time consuming activity, So please spend the necessary time understanding what it takes to edit correctly & accurately.
Please do not edit the map until you have read the Waze Map Editor manual and reviewed the best map editing practices Please do not turn on recording a new road unless you are about to drive on to a road that is not already on the map
Before you begin, please read the information about Google aerial images and the use of Googze (i.e. don't use it!). Consulting a map book or looking up the name of the road should be ok, but do not trace roads from Google maps or Google aerial images.
In some areas which have been gated off, Google Maps may not be correct anyway. Noting the relatively small size of Singapore, nothing beats first person confirmation.
Choosing the correct road type
Choosing the correct road type is important in correctly mapping out your area.
Freeways are free flowing roads with no stop streets or traffic lights. They usually are inter-provincial. For our purposes, Singapore has no Freeways. See example Freeways in the USA.
Basically all the expressways in Singapore; Note that the standard LOCAL abbreviations will be used exclusively, including the official (direction) suffix that appears on maps and signboards.
So if you're looking at the East Coast Parkway coming from the Airport, it should look like this: ECP (City), and the Central Expressway heading south is CTE (AYE).
- Ayer Rajah Expressway - AYE
- Bukit Timah Expressway - BKE
- Central Expressway - CTE
- East Coast Parkway - ECP
- Kranji Expressway - KJE
- Kallang-Paya Lebar Expressway - KPE
- Marina Coastal Expressway - MCE
- Pan-Island Expressway - PIE
- Seletar Expressway - SLE
- Tampines Expressway - TPE
- North South Expressway - NSE
All highway exits and entrances should be labelled as ramps, including Minor highways, especially where elevation changes move traffic onto a carriageway above another road
These should be similar to major highways except they are not classified as expressways in Singapore. Typically with few stops (or none at all) Examples:
- West Coast Highway
- Nicoll Highway
- Bartley Rd East/Viaduct
- Upper Serangoon Rd
- Outer Ring Road System
Ramps are used to map entrances and exits to highways. It is important that you do not use ramps to map slip roads/interchanges between any other roads as this may confuse the client in future versions.
For reference, the naming convention should simply be a "to" followed by what is shown on the signage. This is so that road users can identify when they observe the sign (having been given the instruction to get off at a certain ramp), and not confuse the name with the actual expressway that follows.
examples: Ramps on "To PIE (Changi)"; "To CTE (City)"
For Exits, similarly, it should read as the signage shows, with the Exit Number followed by the road it leads to.
These are roads that are not highways and are heavily used.
These are the thoroughfares that provide the fastest routes around the country, within the CBD, Housing Estates despite having stoplights/traffic lights.
- The “main roads” that run through a city (Shenton Way, Orchard Rd)
- The roads that run around Major Housing Estates or through them (Yishun Ring Rd, Ang Mo Kio Ave 3, 5 and 6 , Toa Payoh Lor 1, Bedok North Rd)
- Major Roads that lead from the City to the major Suburbs (Serangoon Rd, Holland Rd, Commonwealth Ave)
- Main Roads between Suburban Towns (Braddell Rd. Thomson Rd, Paya Lebar Rd)
A general rule of thumb – It’s a Primary Street if it has 3 lanes in each direction. However, a road that has two lanes in each direction may be considered a Primary Street if it connects to a ramp that leads to an Expressway.
Internationally defined as roads adjacant (usually parallel) to a freeway/highway, where a vehicle usually stops out of the way of traffic (a.k.a. laybys) However very few examples of this exists in Singapore (only along the ECP), so the Service Roads have lended themselves to alternative uses:
Here in Singapore, we use it for unnamed roads, examples:
- Sidelanes, Backlanes (example: behind shophouses
- Unnamed Roads outside a Private Property for the purposes (drop off/pick up)
- Roads that lead from carparks to carparks within Public Housing (HDB) Estates
- The occasional unnamed road leading to the back of a large private property
Alternatively, Public Roads that have not been named, can simply be labelled STREETS until a name is given; then updated at a later date.
Dirt Roads/4x4 Trails
Self explanatory. Any road that is non-tarred and non-paved can be considered a dirt road.
Parking Lot Road
Self explanatory. Use this type of road to map out parking lots to shopping centers etc. It is not necessary to map every single lane of the parking lot, just the general exits/entrances.
The proper use of parking lot roads can also help to avoid automated traffic jam reports as well as Map Problems related to Wazers driving in unmapped parking lots. Draw in the drivable portions of the parking lot that are near streets and other roadways. This will prevent the Waze routing server from assuming you must be on the main road when in fact you are stopped in the parking lot stopped.
A road that is not typically open to the public. You can drive on it, physically, but there may be legal (and physical) restrictions or it is a privately maintained road on private land.
- Gated communities with controlled access (Condominiums, Private Estates)
- Schools and Universities
- Military Camps / Restricted Areas
- Business Property with controlled access (gates / guard)
Any drivable road that does not fit into the category above is a street.
Non drivable road
Do not use these categories. They are unnecessary. If you cannot drive on it, what is it doing in Waze?
Naming the road
Here the more information you can provide, the better. This allows for easier searching and quicker identification of turns. As far as possible, please use the name as used by LTA on the Green signs. This includes using Rd, Ave, Lor, Jln, etc, and notice the lack of "." in abbreviations.
Freeways and motorways
Major and Minor Highways
Major Highways have very well defined names, and you should use the shortform 'only', since most drivers are familiar with the abbreviations of these Major and Minor Highways
You should think split major highways. In fact, these are the only roads that 'should' be split. Minor highways that are single lane in either direction should never be split. In such cases you would simple leave out the direction indicator.
Most primary roads will have a name that everyone recognises and a number that not many do.
Normal streets generally just have a name. If the street is a number, it is acceptable to use the number instead of writing it out, i.e. 1st St, 2nd Ave.
Naming the City
Going against the norm, because of the highly dense nature of Singapore, the Area Managers and Map Editors have elected to use the Town/Estate Names instead of just the internationally known city of Singapore. As such, we have Pasir Ris, Hougang, Tampines, Katong, Toa Payoh... etc
With almost a million vehicles on a few thousand kilometers of roads, we have reason to classify a little differently compared to our global brethen who have way more land area to spread out their users.
Waze automatically stores the country, so this is unnecessary. However, the other three are all likely candidates when searching for an address.
Splitting a road
Splitting a road is not advisable as this causes a lot of maintenance when intersections with the split road need to be created. Most of the time you will find that you can get away with aligning the geometry of the road to the center of the split roads, then select the "Separating Lane" option in the edit panel. If you drive close enough, Waze should route you on the correct road.
Splitting roads clutters the map, makes simple four-way crossings a maze, and adds no (or little) extra value.
If, however, you find that GPS tracks are far off, or the client keeps putting you on a different road, then you have no choice but to split the road.
Waze Camera Types
(this summarized section contains references and images from http://world.waze.com/wiki/index.php/Cameras)
These are permanent stationary cameras that monitor violations of maximum speed limits.
Temporary mobile speed cameras should NOT be reported in the client. It takes sometime for a newly reported camera to show up in the client app. Therefore a mobile speed camera will have been gone before any wazer gets an alert about it. These should be reported as a Police hazard.
Red Light Cameras
Please only report genuine red light camera installations and do not use this function to report locations of regular traffic lights.

Tips for successful editing
- In the View Panel select "Highlight Connectivity". When you click a road the cartouche will highlight each road that your selected road can lead to in green, and highlight each road that leads to your selected road in red/orange. This is useful to identify if you have turn restrictions in place.
- Do not delete roads! There is a problem with area managers not being notified of road deletions. There are also a lot of inactive area managers, so these roads will probably never be deleted. Rather edit the geometry and move them somewhere else. This saves you having to draw a new road anyway.
- If you need to move two connected roads far from where they currently are, disconnect them from each other. To do this, click the road, then click the junction where they connect and click "Disconnect road from node". Greatly changing the geometry of road you are not working on will make it very difficult for you to then select that road as the cartouche will think it is still in its original position. If this does happen to you, try click a part of the road that did not move.
- Drawing two roads so that they touch does not automatically mean you can turn from the one to the other. To do this, make sure you add a junction. And to make your life easier, make sure you always have "Enable all turns" checked. This means you can then restrict just the turns that are not possible.
- To select multiple roads, hold down the control key while click on the roads.
- Once you are done with an area, turn on the "Map Problems" layer. This will help you quickly identify problems. If you can't work out what a problem is, look in the view panel for a description. If you still can't work out what the problem is, it might be a small piece of a road underneath. Try moving some of the roads out the way to see if a latent piece of road was left cut off when you added a junction.
- Learn the shortcut keys. They make life a lot simpler!
