Road attributes overview

Without roads, no navigation. On this page, the properties of road segments as found in the left menu pane after selecting are briefly described, with links to in-depth info if available.

Address

Clicking on the address field shows 3 fields: Street, City, and Country. For most road types both Street and City name should be specified, or the checkbox None should be marked.

The country field is normally prefilled with the proper country name, but more are available in border areas.

Alternative name

If a (primary) street name is given, an alternative name can be attributed as well. This can be the same street name with a different city name, or a different street name (with same or different city name). In case of a street in a border area, with adresses in multiple countries, see ???.

TTS/Pronounciation

Behind the street name you'll see a loudspeaker where you can test the pronounciation of the given name (Text to Speech - TTS). Note that we often use abbreviations in the street names to shorten the length. See the page on TTS for details.

Road type

Road type attributes

Directly under the road type are check boxes with extra attributes (add picture).

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)

Headlights required

Next to carpool/HOV/bus lane

Only used when a road is next to 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 Belgium.

Direction

Here you specify the driving direction of the road. Two-way or one-way. Define one-way by the letters showing in the nodes if a segment is selected (A>B or B>A).

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. More info ...

ASC

Lock

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.

Elevation

Elevation levels should be conform how they are in reality.
