[sumo-user] Rerouting and Simulation of Accidents

[Rehab Shahin <rehab.shahin@xxxxxxxxxx>]

Hi,

How can I assign rerouting for vehicles such that they adjust their routes in simulation time based on the travel time on edges?

I have a scenario of a motorway where the demand is created using randomTrips.py. a route file is created where routes are defined and assigned for each vehicle.

I want to simulate an accident on a specific segment of the motorway. what I did is:
- assigned a reroute device for all vehicles ( <device.rerouting probability="1.0"/>)

- closed the edge where the accident happened by  <closingReroute id="2956471#1" disallow="all"/>

The vehicles are queued in front of the edge blocking the road. My understanding is cars don't know about the closed road until reaching there and then they change the route. but what I want to do is reroute based on the travel times on the edges. Is there a way to do this?
Do I have to change the route file to a trip file so that cars don't have predefined routes?

thanks,

Rehab
