Do not forget that we still have a lot of bus lines mapped with the old system. On the other hand you would not add a way twice (one forward, the other backward) but only once without role in the old system. > Before all the stops (because that is how JOSM would sort them) come all > the ways the bus travels along.

Some weeks ago I kindly ask another mapper to use forward/backward as she/he was adding the role "oneway". There is still lots of work to do in tagging bus lines, especially regional ones and forward/backward as long as it is used consistently does not hurt on any type=route. > Jo > > > 2014-09-05 20:40 GMT+02:00 Rob Nickerson <[email protected] > <mailto:[email protected]>>: > > Dave, > > My understanding is the same as yours.
