Real-time queue length estimation for congested signalized intersections

  title={Real-time queue length estimation for congested signalized intersections},
  author={Henry X. Liu and Xinkai Wu and Wenteng Ma and Heng Hu},
How to estimate queue length in real-time at signalized intersection is a long-standing problem. The problem gets even more difficult when signal links are congested. The traditional input–output approach for queue length estimation can only handle queues that are shorter than the distance between vehicle detector and intersection stop line, because cumulative vehicle count for arrival traffic is not available once the detector is occupied by the queue. In this paper, instead of counting… CONTINUE READING
