%% TRACI TEST 2
%   This m-file shows how to use Traci4Matlab.
%   This example uses the files of the SUMO traci tutorial, see
%   http://sumo-sim.org/userdoc/Tutorials/TraCI4Traffic_Lights.html. If you
%   want to test a TraCI command, just uncomment it. The commands are 
%   organized by SUMO object type, some of them needed to be included in 
%   the main loop of the script.

%% MAIN
% The scenario consists of a single intersection controlled by a traffic light
% whose phases are changed if vehicles pass through an induction loop.

% Initialize SUMO from the system. note that it is initialized in graphical
% interface mode. You have to set the SUMO_HOME environment variable
% pointing to your SUMO root directory and modify the windows path to 
% include the %SUMO_HOME%/bin directory.

try
	system(['sumo-gui -c ' getenv('SUMO_HOME') '\docs\tutorial\traci_tls\data\cross.sumocfg&']);
catch err
end


% To test sine vehicle commands, we have to check wether the sumo 0.20.0
% version is installed, because in that version the prefix of the vehicle
% names has changed.
