Hello, The vehicles have a stale internal state. Vehicles only update their strategic lane preferences when changing from one edge to the next. You should be able to fix this by calling traci.vehicle.updateBestLanes() for all upstream vehicles on the preceding edge immediately after re-opening (and further upstream if the preceding edge is short).
