Resumen
Descripción
This paper presents methods for applying GPS devices to evaluate the performance of coordinated
intersections in terms of traffic delays. It illustrates that GPS-recorded data provides detailed
information on traffic delays of individual intersections as well as traffic delays of coordinated
intersections as a whole system, including travel-time delay, stopped-time delay, time-in-queue
delay, approach delay, and total delay. Most of these intersection delays are difficult to measure
manually; however, with GPS-collected vehicle-positioning data, they can be either directly
identified or indirectly derived. Methods for obtaining different types of intersection delays with
GPS devices are introduced.
