[sumo-user] [REROUTING]

Hi guys I wanna implement in my network a rerouting in every edges since that I noticed that usually at a crossing cars are stucked with their initial route even if one lane is empty and the manouver is possible for the car. To avoid this behaviour I thought to put a reroute to every lane (to star

[sumo-user] Rerouting Question

Hi there, More of a generic question – when rerouting a vehicle with vehicle.rerouteTraveltime(), does the vehicle account for traffic as it currently stands or traffic that it estimates will be there once the vehicle reaches the point of congestion? E.g. say a vehicle has 2 possible paths it c

Adding a rerouter element is not enough. You also need to define an interval and a routeProbReroute or destProbReroute element that defines the new route/destination to be assigned.

Hello,Is it possible to reroute by lane?

Currently the vehicle waits until it is transported, but is there a way to have a rerouter in that

Re: [sumo-user] Rerouting Multiple Vehicles

Hello, this is due to the functionality of rerouteTraveltime(currentTravelTimes=True). In order to use the current travel times, all edges are queried for their current travel time and these values are stored for the router to use. This is only done once per simulattion step but may take some time

Re: [sumo-user] Rerouting by lane

You currently cannot trigger rerouting on specific lanes (though I agree that this would be useful: https://github.com/eclipse/sumo/issues/11406). As a workaround you could use rerouter attribute 'timeThreshold' to trigger rerouting for vehicles that are stuck for too long (at least if the problema

The findRoute method currently routes according to travelTime and ignores effort.

1) most likely, no vehicle ever reaches a waiting time of 600s. By default vehicles are teleported after being jammed for 300s 2) the difference is in the way travel times are estimated. The rerouting device averages speeds (and thus travel times) over time with a configurable algorithm. In contras

If they are scheduled for the same step, rerouting happens first and weight updated afterwards. Note, that the rerouting period is counted for each vehicle individually based on their depart time. This means only a fraction of the vehicles will have their rerouting in the update step. Am Fr., 4. D
