The traffic light plans are generated in the absence of any traffic demand information. Hence, no optimizations are undertaken.
To compare different control schemes, I recommend that you test them over a wide range of intersection types and traffic patterns. This approach was taken in the colombo project (http://www.colombo-fp7.eu/) A small slice of testing code founds it's way into sumo: https://svn.code.sf.net/p/sumo/code/trunk/sumo/tests/complex/traffic_lights/loop_flow/ https://svn.code.sf.net/p/sumo/code/trunk/sumo/tools/sumolib/scenario/scenarios/ However, since I was not involved in that part of the project I cannot give you any support on the details. regards, Jakob 2016-05-09 15:45 GMT+02:00 André "Dedeco" <[email protected]>: > Hi, Jakob. > > Thank you very much for your answer. > > Did you follow any optimization model or known heuristic to write this > code?
