Ramp
Road type for entrance and exit ramps.
Street | City | Speed | Lock |
---|---|---|---|
When to apply
- Entrance and exit roads of motorways.
- Entrance and exit roads of bridges and tunnels.
- When a "Exit R/L" is more clear than a "Keep R/L"
How to map ramps
Connect the ramp close to the actual split of the roads. Extend the ramp naturally to create a junction with the road segment, typically at a 10–15° angle. This will allow for consistent timing of exit instructions.
Especially at long exit lanes, make sure not to draw the exit earlier than the actual split, as it has many disadvantages:
- When crossing the node the app will zoom out too early
- The lanes guidance will disappear too soon
- Final instructions are given too early
- It will be confusing when exits follow each other in quick succession
Naming
Ramps are named in the official language of the region where they are located (check the City name).
- Use the name from the road signs
- If there is no road sign, use the official name. Otherwise, leave it blank*
- To indicate the direction of the route, we use ">" in the name, which translates to "in direction of" in the voice prompts (see TTS).
* If no direction can be specified, the ramp is left without a primary street name, and it will inherit ("copy") the name from the next named segment in the exit prompts. This comes also handy when an exit splits up in 2 different directions.
- Exits: If the exit has a number and/or is known by a name, they must be added to the name of the ramp. The exit is followed by ">" and the destination names from the road signs. If there are multiple cities mentioned, separate them by a '/' slash. Preferably only the first two destinations are used.
- Exit # Name
- Exit # Name
- Exit # > Direction or Exit # > Direction / Direction
- Exit # > Direction or Exit # > Direction / Direction
- Exit # Name > Direction / Direction
- Entrance roads normally indicate a certain direction. Use the name or 1st number of the destination highway, followed by ">" and the direction:
- Destination road # or Name > Direction / Direction
- Destination road # or Name > Direction / Direction
- examples:
- E313 > Antwerpen (Belgium)
- N90 > Charleroi / Gilly (Belgium)
- A7 > Luxembourg / Mersch (Luxembourg)
- examples:
When the ramps are both exits and entries, follow the signage as much as possible.
Lock
A ramp gets the highest lock from the connected segments.
