1) Querying multiple edges must be done from your own code by iterating over the ids and calling getLastStepVehicleNumber(self, edgeID) and then summing up the results
2) sumolib supports retrieval of edges in a square centered on a given point with the size specified as 'radius' (half the size of the square). See https://sumo.dlr.de/wiki/Tools/Sumolib#locate_nearby_edges_based_on_the_geo-coordinate. You could easily adapt this function to support rectangles instead of squares. You may also want to take a look at sumo/tools/district/gridDistricts.py which groups edges according to a regular grid. Another related tool is sumo/tools/edgesInDistrict which collects edges within an arbitrary shape. regards, Jakob Am Do., 25.
