Dear Babangida:
Our apologies for the late response.
*1. traci.lane.subscribe('YaJn_0',{constants.VAR_WAITING_TIME})*
Thanks for noticing this problem, it has been fixed in the latest
Traci4Matlab version, available at Github
https://github.com/pipeacosta/traci4matlab, Matlab Central
http://www.mathworks.com/matlabcentral/fileexchange/44805-traci4matlab and
our SVN repository http://gaunal.unalmed.edu.co/svn/traci4matlab/
*2.
traci.vehicle.subscribeContext(awaitingVeh, constants.VAR_WAITING_TIME,20,
{'0x40', '0x42','0x43','0x5b','0x51','0x56','0x7a'})*
Vehicle subscribe commands work when the vehicle is loaded in the
simulation so you have to verify it first. You can achieve a proper context
subscription, as follows:
vehicles = traci.vehicle.getIDList();
if ismember(awaitingVeh,vehicles)
traci.vehicle.subscribeContext(awaitingVeh,constants.CMD_GET_VEHICLE_VARIABLE,20,{constants.VAR_WAITING_TIME});
end
*3. traci.vehicle.getUniversal(constants.VAR_WAITING_TIME,awaitingVeh)*
getUniversal functions are not meant to be used by end users.
Best Regards!
