Long queue estimation for signalized intersections using mobile data

Real Time Queue Length Estimation for Signalized Intersections Using Travel Times from Mobile Sensors

We study how to estimate real time queue lengths at signalized intersections using intersection travel times collected from mobile traffic sensors. The estimation is based on the observation that critical pattern changes of intersection travel times or delays, such as the discontinuities (i.e., sudden and dramatic increases in travel times) and non-smoothness (i.e., changes of slopes of travel ...

Real-time queue length estimation for congested signalized intersections

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 ...

Cycle-by-Cycle Queue Length Estimation for Signalized Intersections Using Sampled Trajectory Data

to be constant and the input and output flows reach equilibrium (2, 10). Further improvement includes providing queue length in small time stamps on the basis of vehicle arrival and departure profiles, first applied in the software TRANSYT (11). This approach was later extended and named the incremental queue accumulation method (12, 13). Stochastic analysis is also introduced to address the st...
