Thank you for the tip with vehicle type, that should solve it for me. ~M.

[sumo-user] Disable rerouting for individual vehicles

[Matěj Kubička]

Hello,

is it possible to disable rerouting for vehicles added to simulation via 
TraCI? -- I need them to follow exactly the path I've set for them. My 
current solution is to call traci.vehicle.SetRouteID at each step. This 
sometimes ends in "route replacement failed" exception (presumably 
because the vehicle is already on another route).

I want to avoid global rerouting disable.

Thanks,
Matej.
