Pedestrians need sidewalks as well as crossings and they must be forbidden from using the vehicle lanes (this happens automatically if you right-click an edge and select 'add restricted lane -> sidewalk'). Otherwise they will interact with vehicles on the road lanes and jump accross intersections. regards, Jakob
