Re: [sumo-user] Get follower information and calibrating IDM for SUMO

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

1) In the latest development version there is traci.vehicle.getFollower (https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version)

2) the parameters and their defaults are listed at https://sumo.dlr.de/docs/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#car-following_model_parameters. You can extract trajectories using fcd-output: https://sumo.dlr.de/docs/Simulation/Output/FCDOutput.html

Hi everyone!

I have two questions and I would be glad if you answer them. 

1) Is there any function to return the follower vehicle's information? For example, getLeader returns the lead vehicle's ID and gap. I need a function to return the follower vehicle's speed and gap (distance between the follower and subject vehicle).

2) How can I calibrate IDM car-following parameters for SUMO? Is there default IDM parameters for SUMO? If not, how can I extract trajectories from SUMO to calibrate IDM for a typical traffic scenario?

Best regards
