====Toll====
 +
In India, motorcycles often don't have to pay toll, unless driving on an Expressway (Expy). There are also toll areas where taxes are payed, generally near State Borders.
 +
 +
=====Full toll / Indian Expressways=====
 +
On most Indian Expressways all vehicles pay toll at the toll booth. Most often, there is no connection to side roads between toll booths, unless these are resting areas or temporary stops.
 +
Select the segments where people cannot drive without paying toll, and check the Toll attribute at the bottom of the restrictions popup.
 +
Example: [https://www.waze.com/editor/?env=row&lon=77.65639&lat=12.85865&zoom=7 Nice Toll Gate]
 +
 +
=====Toll free for motorbikes / No Indian Expressways=====
 +
Other highways generally are toll free for motorbikes. 
 +
Make a junction in the middle of the toll booth. Select the 2 segments going through the toll booth. Add restriction "toll free" for motorcycles. See this [https://youtu.be/qyUWMVARTH4 video]. Don't add any toll restriction on highway segments between toll booths, where side roads are connected, as people can drive there without paying toll.
 +
Example: [https://www.waze.com/editor/?env=row&lon=87.37648&lat=23.49091&zoom=5 Toll Booth (toll free for motorbikes)]
 +
 +
 +
=====Checkpoints=====
 +
At the borders of the states generally are checkpoints. Often they are close to a toll booth, but the road is being split. Commercial vehicles like trucks are lead to a side road where they need to pay toll/taxes. Private vehicles (white plates) can pass on the middle lane without paying.
 +
*On the side roads, make sure to use the same road type and name as the middle lane. Check "toll" in the restrictions popup. Add (two-way) restriction "allowed", and add a new rule for Hazardous Material, Towing vehicle, and Truck respectively.
 +
*On the middle lane, add (two-way) restriction "prohibited" for Hazardous Material, Towing vehicle, and Truck.
 +
Example: [https://www.waze.com/editor/?env=row&lon=80.44260&lat=21.07467&zoom=5 Chhattisgarh Border Check Post]
 +
 +
''Note:'' Always make a junction at the middle of the toll booth. Make sure every lane consists of at least these 2 segments going through the toll booth, see this [https://www.waze.com/editor/?env=row&lon=80.44260&lat=21.07418&zoom=5 example checkpoint].

Welcome WelcomeEditing EditingCommunity CommunityMisc Misc
This page is under construction: more info need to be added

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:

  1. Clear GPS tracks following the aerial when the GPS Points layer is turned on.
  2. Seeing the road in the Street View feature, where that's available.
  3. 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.

In New Roads.png

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

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.

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 Yes
State Highway SH Yes
Asian Highway AH requested
Highway Hw requested
Expressway Expy requested

Notes:

  1. 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:

  1. 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.
  2. 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.

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. All segments of a roundabout are without a street name (check the "None" box).

However, be careful with roundabouts. Sometimes roundabouts should NOT be drawn as a roundabout, to avoid confusing instructions.

Wrong: Roundabout gives wrong 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:

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 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

Toll

In India, motorcycles often don't have to pay toll, unless driving on an Expressway (Expy). There are also toll areas where taxes are payed, generally near State Borders.

Full toll / Indian Expressways

On most Indian Expressways all vehicles pay toll at the toll booth. Most often, there is no connection to side roads between toll booths, unless these are resting areas or temporary stops. Select the segments where people cannot drive without paying toll, and check the Toll attribute at the bottom of the restrictions popup. Example: Nice Toll Gate

Toll free for motorbikes / No Indian Expressways

Other highways generally are toll free for motorbikes. Make a junction in the middle of the toll booth. Select the 2 segments going through the toll booth. Add restriction "toll free" for motorcycles. See this video. Don't add any toll restriction on highway segments between toll booths, where side roads are connected, as people can drive there without paying toll. Example: Toll Booth (toll free for motorbikes)


Checkpoints

At the borders of the states generally are checkpoints. Often they are close to a toll booth, but the road is being split. Commercial vehicles like trucks are lead to a side road where they need to pay toll/taxes. Private vehicles (white plates) can pass on the middle lane without paying.

  • On the side roads, make sure to use the same road type and name as the middle lane. Check "toll" in the restrictions popup. Add (two-way) restriction "allowed", and add a new rule for Hazardous Material, Towing vehicle, and Truck respectively.
  • On the middle lane, add (two-way) restriction "prohibited" for Hazardous Material, Towing vehicle, and Truck.

Example: Chhattisgarh Border Check Post

Note: Always make a junction at the middle of the toll booth. Make sure every lane consists of at least these 2 segments going through the toll booth, see this example checkpoint.

Speed Limit

W4-tachometr.png

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.

General speed limits If there is info on Speed limits in a specific state, it is listed at the India States page, check there first.

Road type Speed limit Rural area Speed limit Urban area WME Road Type Comments
Expressway with access control 120 NA  Freeway 
Highways (multilane, separate roads for directions) 100 70  Freeway   Major Highway   Minor Highway 
Highways all others 70 40  Major Highway   Minor Highway 
Other roads 60 40,20  Primary Street   Street  20 - in small villages and areas with high density of buildings (usual in old parts of the cities); 40 in new or less dense parts of the cities
Toll booth 40 40

These are general speed limits and the Speed Limit Signs will probably be in this range. Please first check if there are specific Speed Limits in the state where you are working.

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 the Local Champs which method to use (lowest/highest/no speed limit, or 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
A stubbed road


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.
