Dear Jacob, Thank you for your response. I increased the default acceleration of the ego vehicle from default 2.6 m/s^2, hence you can see values like 20 m/s^2. Following is an extract of logic I am using -
if <some condition>: # this condition basically checks if distance between pedestrian and ego vehicle is below some threshold limit traci.vehicle.slowDown(ego_veh_id, 0.0, 15.0) traci.vehicle.setSignal(ego_veh_id, 3) # set signal for emergency braking else: traci.vehicle.setSpeed(ego_veh_id, -1) # giving control of ego vehicle back to SUMO, hence setting speed as -1 Could you please advise if I am making any mistake? Thank you.
