T3e Webinars are brought to you by the Intelligent Transportation Systems (ITS) Professional Capacity Building Program (PCB) of the U.S. Department of Transportation’s (U.S. DOT) ITS Joint Program Office (JPO). The purpose of this webinar series is to provide a platform for students to share their research findings.

Ridesharing services have been growing since the start of network service companies in recent years, and will be further enhanced with the deployment of autonomous vehicles in the future. When the daily trip request pattern is stable based on the steady population composition, economy, and city infrastructure in a long time period, one fundamental question is what the corresponding dynamic traffic condition will be if all vehicles are autonomous and can be dispatched in a centralized way. This presentation will discuss how to optimally assign the available vehicles from different depots to satisfy those stable trip requests, while considering the road congestion endogenously incurred by the interactions of those dynamically assigned vehicles.
The audience will learn about:
- Modeling the process of dispatching autonomous vehicles to pick up and drop off passengers with trip location and time window requests;
- Capturing the road congestion incurred by those dispatched vehicles in space-time networks; and
- Developing algorithms to solve the vehicle routing and assignment problems to show the dynamic traffic patterns in future transportation systems.
The target audience includes graduate students, researchers, transportation modelers, and other practitioners who are interested in vehicle routing and dynamic traffic assignment problems.
Xuesong Zhou, Ph.D., Associate Professor in Civil Engineering at Arizona State University
Dr. Xuesong Zhou serves as Associate Professor at the School of Sustainable Engineering and the Built Environment at Arizona State University (ASU).
