Non-drivable roads
The non-drivable road types are:
Non-drivable roads like walking trails and pedestrian boardwalks shouldn't be added, unless there is a good reason. Check the Wiki pages on these road types: Non-drivable roads and Non-drivable roads.
Walking Trail or Pedestrian Boardwalk
Destination
If a footpath leads from a normal road to a Walking Trail, but this path has no destinations / house numbers,
should it be defined as PB or is a PB skipped in the routing and should we take WT without house numbers?
Best use a WT, see picture below.
Public transport
The previous standard "Use Walking trails for public transport" is changed into "use Non-drivable roads for public transport". because both non-drivable roadtypes have now a fix. Preference for PB because public transport lanes shouldn’t have (by accident) destinations.
