Re: [sumo-user] A question about SUMO on setting deceleration

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

To set an exact deceleration, compute the resulting speed and then use vehicle.setSpeed or vehicle.slowDown.

Possibly, you have to override safety features to achieve this. See https://sumo.dlr.de/wiki/TraCI/Change_Vehicle_State#speed_mode_.280xb3.29

Hey everyone,
I am doing a research on the safety improvement of the ACC algorithm. Among them, I need to set a specific deceleration(eg. -3m/s^2) for the vehicle at a specific time. However, I did not find a way to set the deceleration for the vehicle in Traci's documentation. In the documentation, I found setDecel means Sets the vehicle's wished maximum deceleration to the given value. Is there a function in Traci that sets the deceleration instead of the maximum desired deceleration for a vehice at next simulation step?
Best regards,
Xianming
