initial pseudo route should not be written by vehroute output #5639
The problem is not sumo but the duarouter. It considers every route in the input and even a route with 0 probability in the input can be chosen in the output if the cost are low enough (which they are for such a short route). Unfortunately it does not check whether the route is valid at all. Maybe adding --repair already fixes that, I'll check. furtheremore we should modify vehroute output such that it does not include the invalid first "route" consisting of two edges only.
I think/suggest that sumo should not write out the set of the start and end links as a route under the routeDistribution when running one-shot. It is logical that all routes in the routeDistribution should be vaild as prerequisite. Under this condition, what the current duarouter does ist right.
