Roads and their properties
Without roads, no navigation. Drawing the available roads in our map and connect them well is our first concern. On this page, the properties of road segments are described.
When to add roads (and when not)
Indian cities have been growing rapidly, with lots of roads being made and connected to existing roads. If you notice any roads on the satellite layer that has not been added to the base map, please first confirm that they exist before adding them. Do NOT add any roads without either:
- Clear GPS tracks following the aerial when the GPS Points layer is turned on.
- Seeing the road in the Street View feature, where that's available.
- Local knowledge, or confirmation by a local host.
If you doubt an existing road is drivable, please DON'T delete them without prior discussion with the local area manager or one of the champs. And if you're extending an existing road, please ensure that you always verify that the road has been completed and properly connected before extending it.
If you turn on the GPS layer(link to explanation), you can see if the road has been driven on. If the layer doesn’t show any GPS arrows, it’s possible that the road hasn’t been opened for the public, or is just a road that has not been driven on by a Wazer yet.
On the left side of the image, running alongside the Yamuna Expressway, there is a service lane that hasn’t been driven on. Leave it like this. If you live in the region, pay the location a visit to see if the road is open and drivable.
How to add roads is described in the Quick Start Guide.
Non-existent roads
-
1. New Roads
-
2a. Non-existent roads
-
2b. Disconnecting a non-existent road
-
3. Unfinished road
There may be roads that have been drawn in the base-map but may not be in the satellite images, or they may not exist in real life at all. Again, the GPS points will help you determine their status. If the satellite image shows an incomplete road with no GPS points (Pic 2), leave the road in the base map. If it’s already drawn, disconnect the junction nodes to valid roads (Pic 2b). If no road has been drawn (see Pic. 3), go ahead and add the road with the name “Road Under Construction”. Do not connect it to any other roads. The road can then be easily found and completed once the road is opened.
Extremely Narrow Streets
Many cities in India are extremely densely populated. Perhaps this is because they used to be villages that have been absorbed into one large city. Villages often have the same layout and structure. Many of the streets in these areas are too narrow to drive through, and shouldn’t be allowed for routing. You can turn off the Roads layer to have a proper view on the Satellite Imagery.
-
View with Roads layer on
-
View with Roads layer off
As the pictures show, the primary street at the left side of the picture is a proper drivable road. At the right side, the buildings are densely packed and the streets are too narrow to drive through with a car.
If you see streets drawn over these areas, please turn the Roads layer off and verify if the roads are drivable or not based on the Satellite View. Also verify if there are NO GPS tracks by turning on the GPS Points layer. See also the section about Walking trails, which are imported at the google takeover.
If the verifications confirm these streets are not drivable, check the last update. If you see an editor listed there, contact him or her: probably there was a reason to keep the road. If there is no reason, delete them.
Always use extreme caution before deleting segments. If you have any doubt, please discuss it with the Area Manager, or contact one of the local champs.
Road Naming
The naming of the roads in India is quite a challenge. Many roads don't have a name or are referred to as the "Road from A to B". And if there are specific names, they are often duplicates, even withing one city. On top of that, there are many different languages/dialects in use.
Several aspects are important:
- availbility
- searchability
- visibility/readability in the app
- continuous routing
- distinguishing unique addresses
All primary names should be in English, as one of the official languages in India. It makes Waze usable for all Indian people and tourists as well.
The following convention should be followed where possible, although it is acknowledged that you may need to deviate from it in some circumstance. In case of doubt, please consult with your Community.
Street naming
- Enter official streetnames in the Primary name field.
- Primary names should be in English
- Use the abbreviations as stated in the table below
- If a street has two or more names, we choose the shortest as the Primary name, and the other one goes in alternate name.
- try to be consequent and use the same name for all segments in a stretch.
naming of highways:
- highways are indicated by their number, if available, in the primary name field
- Names are written as NH-XX, SH-XX. Asian Highways are abbreviated to AHXX according to international standard
- all other necessary numbers go in alternate name
- we use the numbers as they are on the map;
- we only use new road numbers if it is requested via UR. We then put the old number as alternate name
- names indicating destinations go in alternate name (e.g., Mumbai Pune Hw), if a road number is available;
- AHXX goes in alt name, if NH-XX or SH-XX is available
- only when a highway has a specific name in urban areas that is used in addresses, it can be in the primary name
In case of doubt, please consult with your Community.
Abbreviations
The following abbreviations should be used where possible to conserve screen space.
| Road Name | Abbreviation | TTS Expansion? |
|---|---|---|
| Avenue | Ave | Yes |
| Boulevard | Blvd | Yes |
| Drive | Dr | Yes |
| Junction | J | Yes |
| Lane | Ln | Yes |
| Place | Pl | Yes |
| Road | Rd | Yes |
| Street | St | Yes |
| National Highway | NH | requested |
| State Highway | SH | Yes |
| Asian Highway | AH | requested |
| Highway | Hw | requested |
| Expressway | Expy | requested |
Notes:
- TTS = Text To Speech, used for the navigation voice
City naming
The City field should be used to specify the city, town or village for all the streets in urban areas. Rural roads that are in-between towns should be left without a city name.
Where possible, the simplest unique name should be used.
For very large cities with suburbs, then the neighbourhood should be used in the city name (-is this correct??). This is particularly important for generating useful traffic reports, especially when there are long arterial or ring roads that go through several parts of the city.
In short:
- only in urban areas
- use the simplest unique name (??)
- add/change the city name only when you are absolutely sure of the name
- otherwise, leave as is, or check the _None_ box
In case of doubt, please consult with your Community.
City Smudges
The editor will display the error message "The highlighted road is too far from the city it was added to" when attempting to add a duplicate name. This is to prevent smudges and means that a different name will need to be chosen for that town or village.
For problems with smudged cities, we are currently gathering several solutions and workarounds.
Junction Naming
Major junctions, particularly on Highways, should be labelled with a Place. Under no circumstances should the road name or city name fields of a segment be used for naming of a junction. Detailed information and examples have been moved to the Wiki page about Places.
Road Types
Road type designations in Waze are determined by the physical layout and use of the road, not by the name of a road. Road types do not affect naming.
Some road type classifications are influenced by city size, traffic density, and regional conventions. For example, in a very large city a primary street may have three or more lanes in each direction on a divided road. While in rural areas unpaved roads could be a primary street or even a highway if that is necessary for routing.
While editing the maps, you may notice that some of the roads are not labeled properly. This means, the road type might be wrong (a highway is marked as a street) or that one road contains segments with more than one road type (a highway is marked as Freeway, highway and primary at different segments).
The importance of proper labeling is in two aspects:
- When viewing the map, the 'bigger' roads should appear at the far zoom levels. Without proper labels, the 'zoomed out' display can be very confusing.
- When planning a route, major roads will get priority over smaller roads.
Before changing road types of highways, please discuss with a senior editor, as it may break routing.
General guidelines
- The main roads in a district or town should at least be set to primary.
- If segments will be used for through-going traffic or for longer distances connecting districts or towns, they should at least be mH (minor Highway)
- Main interconnecting roads with fast traffic should at least be MH (major Highway)
Always try to connect a road to a same level of road type or higher. Thus, Waze should be able to route from primary to primary (or higher), from minor to minor (or higher), from major to major (or higher), and from Freeway to Freeway. Another way of explaining this, is that you should be able to continuously drive on the same or higher type of segments for the routing engine to use that road type in the calculations.
This means we sometimes need to make small roads mH, for the possibility of calculating long distance routing. Please discuss with the management if anything is unclear.
The following convention should be followed where possible, although it is acknowledged that you may need to deviate from it in some circumstances.

Highways
Highways are typically numbered or named roads that can be used for long routes.
Except for ramps, follow the naming convention:
- highways are indicated by their number, if available, in the primary name field
- Names are written as NH-XX, SH-XX, and AHXX
- all other necessary numbers go in alternate name
- we use the numbers as they are on the map
- we only use new road numbers if it is requested via UR. We then put the old number as alternate name
- names indicating destinations go in alternate name (e.g., Mumbai Pune Highway), if a road number is available
- only when a highway has a specific name in urban areas that is used in addresses, it can be in the primary name
In case of doubt, please consult with your Community.
Freeway
Freeways are Expressways and National Highways appointed by champs. At least the red lines in the picture below need to be of the type Freeway to ensure long routes.

Off-road / Not maintained
In former days, this category was called Unpaved, and before Dirt Road/4x4. Because there are unpaved roads that are very well drivable, this type is now used for very bad roads you don't want Waze sent you normally, or roads that are not drivable during some periods (like heavy rain fall), or need a 4x4 car to go over it. From now on, for drivable roads that are unpaved, select the proper road type and use the Unpaved attribute.

Private Road
- The Private Road type will only be used when you have your destination on that road, or if no other road can bring you there. It is not used for through-going traffic.
- Only mark the entrances and exits to and from residential/restricted areas with the Private Road type. Especially on larger terrains, like an industrial area, make sure to mark the roads between entry and exit as normal street to ensure proper routing.

Non-drivable
Concerning Non-Drivable roads: Most aren't worth adding, as Waze is an app aimed at commuters who drive a car.
Walking Trail
Due to the import a few years ago, there are still many walking trails in the map. Generally, these are unpaved roads. Check the last editor and discuss your ideas. If there is no editor listed, check if they can be used to drive. If so, choose the correct road type (often Unpaved). If not, decide if they if they are needed because it leads to a destination that is important for drivers, or perhaps just for orientation.
In case of doubt, please discuss with the area manager or one of the local champs, to be found on the community page.
Pedestrian Boardwalk
?
Stairway
not in use
Railroad
Railways can be helpful in orientation, or needed when they are close to a road to distinguish different speeds.
- Leave street- and city name blank (check the None box)
- Ongoing routing should be enabled (set arrows to green for continuing on rail road). If the railroad crosses a drivable road, please connect them, with turns to and from the drivable road restricted (red arrows). If they don't cross at the same elevations, just make sure to set the right elevation level.
- lock: 2
- Direction: two way
Also, add a train station as an Area covering the building. If there is no building visible from the road, use a Point Place.
Runway/Taxiway
not in use
Roundabouts
A special kind of road type is the roundabout. You cannot find them in the list of road types, but you need to draw (add link) them separately. Roundabouts, rotaries, or traffic circles, are unique segments in the Waze routing engine. When a driver approaches a roundabout segment, a specific icon is displayed in the turn direction area of the display with a number corresponding to the exit count from the driver's entry into the roundabout. Manually creating a circular road will not tell Waze to navigate the area as a roundabout. A roundabout gives you instructions like: "On the roundabout, take the 3rd exit" or, "On the roundabout, go left" depending on the way of drawing. A roundabout should be assigned the same road type of the highest classified, ongoing connected road.
However, be careful with roundabouts. Sometimes roundabouts should NOT be drawn as a roundabout, to avoid confusing instructions.
Always ask yourself, what kind of instruction will you hear or see in the app? Do that for every road into every direction. In the picture, if you are at segment 3, and want to go to segment 5, you would now get "On the roundabout, take the 2nd exit". That is not conform the actual situation for the driver, who just drives straight. In this case, a roundabout would thus yield confusing instructions.
Some alternative solutions for such junctions are the following:
-
Solution to the example
-
Simplified junction, for smaller roads. This still yields the right instructions
-
Looks like a roundabout, but acts like a normal junction.
-
Always make sure the corners yield the right instructions
Intersections that could cause confusion like described above, should be locked to level 3. If you have any doubt, please discuss with the area manager or one of the local champs, to be found on the community page.
Road attributes
Directly under the road type are check boxes with extra attributes (add picture).
Toll Road
Not an attribute anymore (pic needs to be updated. You can find this option at the restrictions (link to be added) now .
Unpaved
Used for roads that are unpaved, but very well drivable. Can be attributed to every road type. For roads that are badly maintained and (often) not drivable with a normal car, use the road type Off-road / Not_maintained.
Tunnel
Check this box if the road goes underground or under water. Because of bad GPS and/or internet reception in a tunnel, we need to mark it to be able to still get the right instructions.
- On both entrance and exit, create a new junction node
- Mark the checkbox for tunnel (only for the part that physically goes underground)
- Elevation should be set to -1 (or lower if necessary)
Next to carpool/HOV/bus lane
Only used when a road has a lane that is used by different kind of traffic with different speed, like a bus lane. HOV is a type of road in the US where only some cars may drive, not applicable in India.
Add restrictions
Direction
Speed Limit
While updating the roads, you may as well add speed limits (SLs). Notice that they may differ accross states and may also be adapted locally.
Please check if there are existing SLs and make sure not to override them.
Speed Limits in India are expressed in km/h. As we cannot use WME Street View to verify the Speed Limits, we will enter them according to the following guidelines. If there is info on general Speed limits in a specific state, it is listed at the India States page, check there first.
-table with general speed limits to be added-
These are general speed limits and the Speed Limit Signs will probably be in this range.
Notes:
- The limits shown above apply only if there are no other signs present, as the signs may prescribe a lower or a higher speed limit. We are dependent on local editors to verify these speeds.
- currently WME allows to specify only one speed limit for a single road segment. If a road has variable speed limits, check with your group leader what method to use (lowest/highest/no speed limit, or map only the speed limit which is in effect most of the time during daylight hours/most hours of the day/days of the week).
Elevation
Elevation levels should be conform how they are in reality.
Lock
As the map of India still needs a lot of improvement, we don't want to lock too much that could block starting editors. However, to ensure routing -especially over large distances- we do use locks for some roads according to the table below. Roads that need more protection because of special situations (construction, complicated design, frequent editing errors) may be locked higher. Make sure to thoroughly check the routing in the live map, before you lock the roads.
If you need to edit a road above your lock level, ask an unlock or ask a higher level editor in one of the communication platforms to do the edit for you.
| Road type | Lock level |
|---|---|
| Freeway | 5 |
| Ramp | 5 |
| Major Highway | 4 |
| Minor Highway | 3 |
| Primary Street | 2 |
| Street | Auto (1) |
| Parking Lot Road | Auto (1) |
| |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-| | 2 |
| • • • • Ferry • • • • | 5 |
In areas that still need a lot of work, don't lock. Make stubs to the roads: making a short low-level segment for each exit that a low-level editor can attach to.
