Thanks Wanmil, Access flags look ok now in gpsmapedit.
Bicycle routing still takes the motorway Tested it from city nodes Amersfoort-Apeldoorn
Did you (or if not can you) check the motorways with GPSMapEdit? Is the flag set that prevents bicycle routing on motorways? In such a case it must be a MapSource (or GPS) bug. Or it is an undisclosed map feature...
The OSM generic routable (osm data 8/10) calculates a route not over motorways or for cyclists forbidden roads. However, if I calculate a route between Amsterdam and Amersfoort, it takes the A1 motorway too :(
So regarding bicycle routing it seems random whether it accepts the mkgmap access rules or not. Car routing looks ok.
I have to rework my bicycle styles completely to test the mkgmap-mergeroads further.
