Re: [sumo-user] Routes and traffic lights

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

- vehicle routing in the simulation (trips and device.rerouting) only considers traffic light phases in the aggregate: edges with traffic lights may have higher average travel times that those without. (https://sumo.dlr.de/docs/Demand/Automatic_Routing.html)

- pedestrian routing across intersections takes the current traffic light phase into account when deciding which sequence of crossings to use for a diagonal movement

- you can use current traffic light phases for routing by overwriting the edge weights used for routing. The actual calls needed for this differ according to the way that rerouting is triggered: https://sumo.dlr.de/docs/Simulation/Routing.html#travel-time_values_for_routing. Note that you will need multiple weight-setting calls per edge if you also want to take into account how traffic light phases are expected to vary over time. (light is green now but red by the time the vehicle arrives).

Jakob

Hello,

after I did not find a concrete answer about this topic: Is there an
influence of the traffic lights / traffic lights phases on the routes while
the routes are being generated? Or does Sumo only have a look on the
shortes/fastest routes while generating them?
If not: Can the traffic lights (phases) be considered during routes
generation?

Kind regards,
Jens
