[Talk-transit] Help: Bus Stop Data Extraction for Bus Routing Service

Hi,
 

We would like to extract public transport data for public transit routing service in Sweden.

 

When we came to extract bus data from the element of “Relation”, we found the stopping point data in a relation are always incomplete in bus route data, meanwhile, we also noticed there are bus stopping points in the ways which are contained in a bus route relation.

 

What is the difference between the stop nodes within a relation and the nodes tagged as “bus_stop” in highways which are also contained in a relation? 



Do the stop nodes within a relation merely refer to the passenger waiting point, whereas, stops in highway contained in a relation represent the vehicle stopping points?  

 

We get some references from http://wiki.openstreetmap.org/wiki/Buses, but still don’t know clearly how to deal with those bus stop data.

 

Any information or advise about how to deal with the bus stop data for performing bus routing service would be highly appreciated.

 

Regard,



Grace
