rework teleporting behavior when blocked by stopping vehicles (trac #1078) #1078

Closed behrisch closed 2 years ago

behrisch commented 10 years ago

currently, teleports are only considered for the lead vehicle on any lane. If the leading vehicle has a stop, the vehicles behind it are blocked indefinitely. If the leading vehicle is removed (i.e. because it's route ends) and the first blocked vehicle exceeds gTimeToTeleport it teleports instantly.

The fact that a vehicle teleports once it is free to drive is surprising and should be fixed. Suggestion

this behavior shows up in sumo\tests\sumo\output\tripinfo\teleport

b) is probably the easiest fix but does not model squeezing past a broken vehicle
