Proposed features/Public Transport v2 Vehicle Type "coach"
|Public Transport v2 Vehicle Type "coach"|
|Status:||Draft (under way)|
|Definition:||Add the new vehicle type "coach" for Public Transport v2|
There's a clear difference between buses that only run inside a city (transit bus service, short distance) and buses that interconnect two or more cities (intercity bus service, long distance). It is almost as significant as the difference between route=train and route=tram which indeed is tagged by two different values.
An intercity bus service (North American English) or intercity coach service (British English and Commonwealth English), also called a long-distance, express, over-the-road, commercial, long-haul, or highway bus or coach service, is a public transport service using coaches to carry passengers significant distances between different cities, towns, or other populated areas. Unlike a transit bus service, which has frequent stops throughout a city or town, an intercity bus service generally has a single stop at one location in or near a city, and travels long distances without stopping at all.
The introduction on the OSM-Wiki-Page about Buses also mentions "coaches" apart from "buses" and "trolleybuses", but only the latter two have different tagging values, whereas coach routes are supposed to use the same route=bus. This leads to confusion between the two types of (inter- and intra-city) bus routes because there is no difference visible to rendering engines (and thus to the user) or other data consuming programs.
Also consider that there's already a OSM-Wiki-Page for the tag route=coach that states that it is unofficial and lacks a proposal. Nevertheless, there are already 59 relations that use this tag (as of October 1st) and there are a lot of coach routes to change. See also Fernbuslinien (in German) where it is proposed to use route=coach instead of route=bus.
There are a lot of examples all around the world that are currently not distinguishable from city bus routes, see sample Overpass-Query for Germany.
