An Adaptive Signal Control Scheme for Intersections Experiencing Railroad Blockage

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The presence of an at-grade railroad crossing nearing a signalized intersection has a significant effect on traffic flow. When trains cross at grade, traffic flow can be significantly restricted. Vehicle queues may spillback to the upstream intersection and block it. In this paper, an adaptive signal control scheme is proposed to prevent this type of intersection traffic jam. This adaptive control scheme requires a speed detection system on the downstream link. The detectors should be strategically located such that a signal switching could be triggered when an intersection traffic jam is about to happen. This adaptive control scheme is based on the status of the downstream queue status and the traffic signal state. At the end, a microscopic traffic simulation software is used to evaluate the proposed adaptive control scheme. The simulation results show that the adaptive signal control scheme can work effectively to prevent this type of intersection traffic jam.
