Hi ,

I'm a new user of SUMO. As a part of my research, I was trying a code to access the speed and position of the vehicles around my ego vehicle using Traci vehicle contextsubscription command. Given below is the command I used:-

traci.vehicle.subscribeContext('2567#6',...

       traci.constants.CMD_GET_VEHICLE_VARIABLE, 20,...

       [traci.constants.VAR_SPEED,traci.constants.VAR_POSITION]);

It is giving an error :-

Error using vehicle.subscribeContext

The value of 'varIDs' is invalid. It must satisfy the function: iscell.

Error in traci.vehicle.subscribeContext (line 34)

p.parse(vehID, domain, dist, varargin{:})

Error in vehicleconsub (line 58)

       traci.vehicle.subscribeContext('2567#6',...

Could anyone help me with this. Thanks in advance !

Regards,

Surya
