You would then write another script to read edge-based traffic measures (traffic density, average speed) generated by the simulation and also load the set of edges for each polygon to aggregate the traffic measurements yourself. It may also be necessary to load the network itself to retrieve edge lengths for this aggregation (we have a python library to read the network: http://sumo.dlr.de/wiki/Tools/Sumolib)
