Dear Andres,
Thank you for your response. However, i tried but now have another
challenge. this is the printed result.
awaitingVeh =
'veh13357'
vehicles =
Columns 1 through 3
'veh13345' 'veh13349' 'veh13353'
Column 4
'veh13357'
Error using vehicle.subscribeContext
Argument 'vehID' failed validation ischar.
Error in traci.vehicle.subscribeContext (line 34)
p.parse(vehID, domain, dist, varargin{:})
Error in signalizedControl (line 108)
traci.vehicle.subscribeContext(awaitingVeh,constants.CMD_GET_VEHICLE_VARIABLE,20,{constants.VAR_WAITING_TIME});
what could I be doing wrong please?
Thanks you.
Kind Regards.
