Queue estimation for isolated signalized intersections in intelligent vehicle-infrastructure cooperation systems

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 ...

Modeling Multiple–Vehicle Property Damage Collisions in Urban Signalized Intersections

Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...

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...
