Ramp

We are currently updating the pages to include all regionally different guidelines. If you find inconsistencies, please refer to the English page. Thank you!

 Ramp 

Road type for entrance and exit ramps.

Attributes

Street	City	Speed	Lock
	optional		4/5

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 18–55° (to meet Falcon Snapper) 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

Lane Guidance

Do not add lane guidance for simple exits, where the number of lanes before and after the exit remains the same (for example, a 2x2 has an exit lane and then returns to 2x2). For other scenarios, use the guidance in Lane Guidance.

Enhanced TIO

For freeway exits, the fields in the Enhanced TIO should be completed as follows:

• Visual instructions: Name of the exit, if known, and otherwise the road shield (if applicable) and main direction. For example, on the E411, the exit names "Overijse" and "Rosières" are known, so that's what we use. If the name isn't known, we use the road shield and main direction ("Nxx Charleroi").
• Toward: Road shield if applicable and directions as shown on the signs at the exit. For example, "N253 Terhulpen". Don't repeat info from the visual instructions.
• Voice Prompt: Adapt as needed.
• TTS: "Afrit" / "Sortie" depending on the region, followed by the number of the exit and the name. For example "Afrit 3 Overijse" or "Sortie 4 Rosières".

See Enhanced TIO for more information.

Naming of ramps

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 # and name on white board in Flanders; the destinations are on the blue board

Exit # Name

Exit # > Direction or Exit # > Direction / Direction

Exit # Name > Direction / Direction

examples:

• Afrit 19 Massenhoven > Lier / Zoersel (Belgium) - see picture
• Ausfahrt 39 Eynatten (Belgium)
• E313 > Luik / Hasselt (Belgium)
• Sortie 8 Louvrange > Louvain / Grez-Doiceau (Belgium)

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

examples:

• E313 > Antwerpen (Belgium)
• N90 > Charleroi / Gilly (Belgium)
• A7 > Luxembourg / Mersch (Luxembourg)

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.
