ABOUT THE WEBINAR:
Vehicle scheduling in conflict areas, particularly for transit vehicles amidst mixed traffic, is a critical concern in urban transport networks. To tackle the complexities arising from dense vehicle populations and the imperative of transit priority, our study introduces two strategies for guiding connected automated vehicles (CAVs) through general conflict zones. The first strategy advances a Branch-and-Bound algorithm that expedites the scheduling process by embedding traffic system rules with a preferential bias towards transit vehicles. The second strategy focuses on diminishing the problem’s complexity by reducing the number of controlled units. Theoretical analyses illustrate that the optimal solution gap between the single-vehicle-based and the platoon-based problems is bounded. A series of numerical experiments validate the effectiveness of our proposed strategies, demonstrating that transit-prioritized vehicle scheduling can facilitate efficient transit passage through intersections with minimal compromise on the optimality of the overall traffic flow.
