option --check-lane-foes.all does not propperly affect internal junctions (trac #2614) #2614

Open behrisch opened 8 years ago

behrisch commented 8 years ago

vehicles that turn left via an internal junction still yield for right-turning vehicles that target different lanes. This leads to problems in right-turn-on-red scenarios if the right turning vehicles are allowed during the lef-turn phase.

The reason is that in NBEdge::buildInnerEdges, the vector tmpFoeIncomingLanes is filled using forbids() without regard to lane-foes
