[sumo-user] Adding penalties to current travel times.

[Shekar V via sumo-user <sumo-user@xxxxxxxxxxxxxxxxxxxxx>]

Hello

I am trying to run a simple simulation where all vehicles move from Point A
to Point B. There are only 2 routes to travel from A to B, say Route1 and
Route2.

I want to "discourage" the router from assigning vehicles to Route1 by
adding a penalty/weight to the route. To do this, I am using weight files
with the traveltime attribute along with the traci command:
traci.vehicle.rerouteTraveltime(self, vehID, currentTravelTimes=False)

I understand that by doing this the vehicle will completely ignore the
current travel times and route according to the weights defined in the
weight file. What I want to do is add a penalty to the current travel
times, so that if Route 2 becomes congested, new trips will be routed
through Route 1.

An approach I was considering is:
travel_time = traci.edge.getTraveltime(edgeID)
new_travel_time = travel_time * penalty
traci.edge.adaptTraveltime(edgeID, new_travel_time)

If there is an easier way to solve this issue please let me know.

Thanks
Shekar
