The U.S. Department of Transportation (USDOT) is hosting a series of webinars on emerging academic research in various aspects of intelligent transportation systems or smart communities. This 90-minute webinar will present the work by the University of Alabama that develops a digital twin for live traffic monitoring and models to support proactive traffic incident management. The research is funded by USDOT’s Advanced Transportation and Congestion Management Technologies Deployment (ATCMTD) Program through the West Central Alabama Advanced Connected Transportation Infrastructure & Operations Network (ACTION) initiative—Alabama Department of Transportation (ALDOT) and Alabama Transportation Institute (ATI).
The target audience includes researchers and practitioners from the public sector, private sector, and academia that deal with transportation systems management and operations.
Objectives of this webinar are that the audience will gain an understanding about:
- A digital twin for traffic monitoring:
- A networkwide traffic simulation based on real-time detector data
- Traffic signal optimization for connected vehicles
- Proactive traffic incident management:
- Identifying traffic incidents based on probe vehicle data
- Estimating the impacts of traffic incidents on traffic flows
