摘要

Probe Vehicle is a new generation of traffic detection technology. Most research and applications about probe vehicle focus on traffic information service system instead of traffic signal control system. This article proposes a probe-based adaptive traffic signal control method for urban corridors. The key objective of the method is to postpone traffic jam and maintain the capacity as long as possible. The proportion of the non-stop group is chosen as the indicator of traffic conditions. It can be estimated using probe vehicle data and can be used to identify traffic state variation after saturation. The proportion of the non-stop group is used to evaluate the urgent degree of each link and a rule-based model is used to assign green time to each intersection using the urgent degree measures. This control strategy is tested under a microscope simulation model. Results indicate that this model can significantly postpone congestion and maintain the capacity of the corridor.
