Re: [sumo-user] change vehicle arrival rate on the fly from traci

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

There is no direct way to manipulate flows. You can delete individual flow vehicles to decrease the flow and you can add additional vehicles, using an existing routeID to increase traffic using vehicle.remove and vehicle.add.

An alternative would be to define calibrators in xml and manpulate them via TraCI:

Actually, I start the simulation campaign by loading  .rou.xml file  containing all vehicle routes types  flows vtype distribution etc.

and i want to change traffic or arrival rate  on the course of the latter simulation from Traci

without adding new vehicles ; since a repeated vehicle emissions ("flow"s) is defined in the .rou.xml file.

Any solution ?

best regards.

Yes. By adding more vehicles using traci.vehicle.add: https://sumo.dlr.de/docs/TraCI/Change_Vehicle_State.html#add_alias_addfull_0x85

Can vehicles' arrival rate on a lane be changed during a simulation from traci ?

best regards.
