Hi Arslan, Marcus' proposals are all perfectly fine, but since you asked for sumolib functionality I want to direct your attention to the getNeighboringEdges and getNeighboringLanes functions of the network http://www.sumo.dlr.de/pydoc/sumolib.net.html#Net. Both take a point in the plane and a radius and deliver all edges / lanes in the radius (together with the distance) which you can compare with the route then. There is no TraCI involved and be aware that you should have installed the python rtree package when using the methods with large networks.
