Hi Jakob,


To check my understanding if I want to assign CACC  with default values then a simple attribute “carFollowModel="CACC"” would be enough, am I right?

the attributes for CACC and ACC are currently not accessible via TraCI getParameter. If you do not set them in your xml input, they take on the default values listed at

Hi ,


I am using CACC model for vehicles even then the speed improvements were not found. I want to check if the attributes of CACC are implemented or not for a vehicle in traci, for ex “speedControlGain”. What would be the traci command for this? Should this work “ traci.vehicle.getParameter(veh_id, "carFollowModel.speedControlGain"))”


Have all the attributes of CACC are implemented into SUMO so that if I just specify CACC to a vehicle type in route file is that sufficient or should I use traci to set the parameter values. Similarly can I know for ACC as well?
