[sumo-user] Car following model and leaders

[Hriday Sanghvi <sanghvih@xxxxxx>]

Hello,

I am currently using the Krauss model for car-following following a very simple 2-lane scenario. When I use the traci.vehicle.getLeader(vehID=vh, dist=0.0) command, for a vehicle f.1, I get the output ('f.0', 1.0995103573504839) - which is telling me that it is ~1.1m in front of the vehicle f.1.

From what I can tell, it is calculating this value from

Front bumper position of vehicle f.0 - Front bumper position of vehicle f.1 - Length of vehicle f.0 - Default mingap (2.5 m) = 13.70 - 5.10 - 5.0 - 2.5 = 1.1m

Is my understanding correct? So if I want the actual distance between the ego vehicle's front bumper and the leader vehicle's back bumper, I need to add the value of "minGap"? Is the "dist" parameter related to this?

Thank you.

Sincerely,

Hriday.
