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?

Regards,

Hello,
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?

Regards,
V.H.Pradeep
