Abstract: This study developed a dynamic traffic control formulation designated as Dynamic Intersection Signal Control Optimization (DISCO). DISCO considers the entire Fundamental Diagram, which is essential for controlling congested and transient traffic. As a dynamic model, DISCO works with time-variant traffic patterns and derives dynamic adaptive timing plans. In this paper, we applied DISCO to a congested spot in Hong Kong and compared its performance with TRANSYT. Results showed that DISCO outperformed TRANSYT in all the scenarios tested. In some scenarios, DISCO could further reduce delay by as much as 33%. DISCO shows promise as a new approach for demand-responsive traffic control.
