The quality of service in urban transportation networks is determined mainly by the performance of the intersections. In particular, signalized intersections play a significant role in regulating the traffic in urban transportation networks. As a result, it is essential for transportation authorities to have a system, which can locate poorly operating intersections in the network and rank them for potential improvements. In practice, intersection performance is typically evaluated through the use of models such as HCS (Highway Capacity Software) or Synchro.
