Generally, you will have to perform a recursive search in the road network since there may be multiple edges between adjacent tls even if they are in close proximity (due to changes in lane number of speed). You can use sumolib to traverse the network graph: https://sumo.dlr.de/docs/Tools/Sumolib.html
