Trying to modify the Parameters of W99 from Traci #15421

Hi everyone, I'm trying to apply genetic algorithm to calibrate the parameters of W-99 model (from CC0 to CC9). I've tried getparam, getparameterwithkey, and others. It kept returning empty space. I'd be glad if anyone could help with this.

This isn't supported at the moment. The proper API syntax would be traci.vehicle.setParameter(vehID, "carFollowModel.cc1") but the functions MSCFModel_W99::getParameter and MSCFModel_W99::setParameter are missing.

pull requests are welcome
you can set cc0 as traci.vehicle.setMinGap
a possible workaround is to generate xml inputs with the desired W99 parameters and start the simulation from scratch (traci.load)
