Dual Carriageways
The following convention should be followed where possible, although it is acknowledged that you may need to deviate from it in some circumstances.
A road can be split into be 2 one-way roads if all of the following conditions are met:
- The central reservation is > 15m
- There's a visible gap between the GPS traces
- It is split by physical barrier (Concrete, Armco, pedestrian barrier etc)
Pedestrian refuges and painted road separation (cross hatching that can be driven over) should not normally be split.

| You have to keep in mind, that Waze actually is not supporting split roads - i.e. all reports to the opposing lane of a split road are in vain, because for the client this are two seperate one-way-streets, it doesn't know any opposing directions. Road splitting has been done way to often in the past, so we "increased" the conditions to be met before splitting a road. But if you have a perfectly working splitted road that does not meet the above stated conditions don't unsplit it. It's a lot of work with the risk of loosing valuable traffic data and house numbers (if done wrong). |
Motorway Carriageway Naming Convention
Whenever possible, on split roads, name carriageways with the direction of travel. Insert the direction of travel at the end of the road name:
Examples: 1. M3 - Eastern Fwy (Inbound) 2. A4 - (W) 3. M25 - (ACW)
This makes traffic and incident reports much more useful and helps with navigation.
Exit and Entrance ramps (on/off ramps)
For the best balance between information and screen real estate, the following conventions are used. All ramps will be set as the 'ramp' type in the Waze Map Editor and be locked at the same level as the freeway which joins to them. The name of the road, route number (if applicable) and compass direction (for entrance ramps) should all be added for clear guidance to be given when using the Waze app.
PLEASE NOTE:
Naming is only to be used for freeway / motorway style on and off ramps. Please do not add names to slip lanes on regular roads, as this is unnecessary for directions to work.
Exit ramps:
- If the exit sign shows a number as well as a street or highway name, the exit ramp should be named "Exit 15: SR16 - Police Rd".
- A colon has been added because it adds a pause, which makes the Text-to-Speech directions easier to understand.
- If the exit is not numbered, "Exit to C722 - Donnybrook Rd" will do. The colon is not necessary when there is no exit number.
- If a single exit serves multiple roads, use a slash with leading and trailing spaces: "Exit 32: Terminator Blvd / Total Recall Rd".
- If an exit number contains one or more letters, include it exactly as displayed on the sign: "Exit W2: ALTNR1 - Kings Way".
- Include everything that is present on the last sign prior to the exit. Do not combine all possible pre-ramp signage into the single ramp segment name.
- If the exit off the main interstate or highway serves multiple exits further down the road, it may be advisable not to name the first exit ramp, to name only the ramps which are the first one to a distinct destination. The Waze client will give all the proper exit and keep left or right instructions to guide the driver to the correct exit, even if the first one is not named. That said, this should only be done if the signage for the first ramp is the same as that on the subsequent, named ramp.
Entrance ramps:
For entrance ramps, use this format. For example:
- "Entry to M1 - Monash Fwy (NW)"
- "Entry to M39 - Goulburn Valley Fwy (N)"
Roundabouts
To aid navigation instructions, roundabouts should typically remain without a street name
- City: enter either suburb/city
- Street: Tick "None"
- where the client comes across a segment with no name it will use the next named segment as the next named instruction whilst retaining any turn signals.
If the roundabout does have a proper, signposted name, then this can be labelled using a 'Junction/Intersection' type landmark that fills the centre of the roundabout.
