Title: Use of Occupied Area for Queue and Delay Estimation at Signalized Intersections Under Mixed Traffic Conditions
Accession Number: 01628110
Record Type: Component
Abstract: Queue length and delay are the primary performance measures of signalized intersections and their accurate estimation is essential for proper management of traffic. However, measurement of queue and delay is difficult due to their spatial nature. Their measurement becomes more challenging in case of mixed traffic conditions, where vehicles of varying static and dynamic characteristics occupy the entire road space without any lane discipline. In this study, model based estimation schemes were developed for queue and delay at signalized intersection using occupied area as measurement, for two different scenarios, namely queue within detector (QWD) and queue beyond detector (QBD). Sensor errors were explicitly incorporated while using automated detectors. The evaluation showed very good performance of the proposed method, indicating the efficacy of the scheme in cases with detector errors. The developed estimation schemes can be used as part of travel time information applications in real time Intelligent Transportation System (ITS) implementations.
