On the morning of June 26th, Professor Wei Heng gave a special report entitled“CAV-Data-Driven Intelligent Adaptive Traffic Signal Control”to the teachers and students of our base in the conference room. This report shows the main research results of Professor Wei in recent years, oriented to adaptive signal control systems. With the development of vehicle communication and vehicle communication technology, data collected from networked vehicles can be used to capture a complete traffic state map for adaptive signal control. This study proposes a new model that enables real-time data exchange between vehicle and vehicle communication and vehicle communication to achieve adaptive control. In addition, the networked vehicle can be used as a moving track sensor to overcome the problem of insufficient traffic data. Preliminary studies have shown that when implementing an optimization strategy at a single intersection, the average control delay per vehicle is reduced, and the traffic efficiency at the intersection is significantly improved. After the special report, Professor Wei had a heated discussion on the contents of the report with the teachers and students of the base. The content of the report received wide acclaim from the teachers and students. More than 20 young teachers and graduate students from the base participated in the seminar.
