University of Connecticut's Fei Mao presented Learning for Robust Control and Optimization: Efficiency and Safety of Autonomous Transportation Systems at 4 p.m. Nov. 1 at the ITS Transportation Seminar in 290 Hearst Memorial Mining Building.
Abstract
Ubiquitous sensing in smart cities enables large-scale multi-source data collected in real-time, poses several challenges and requires a paradigm-shift to data-driven cyber-physical systems (CPSs) that integrates optimization, control and machine learning. For instance, how to capture the complexity and analyze the dynamic interplay between urban-scale phenomena from data, and take actions to improve service efficiency and safety, is still a challenging problem in transportation systems. In this talk, we first present a data-driven dynamic robust resource allocation framework for autonomous ride-sharing and carpool systems, matching vehicle supply towards both current and predicted future demand. With spatial-temporal uncertainty of demand prediction, we then prove and develop computationally tractable methods that provide probabilistic guarantees for the system’s worst-case and expected performance. A dynamic pricing model is also designed for travel time reliability during peak hours. We show that the performance of the ride-sharing system is improved based on world taxi operational data. Lastly, recent work about an information sharing and decision-making framework considering safety and efficiency of connected autonomous vehicles is introduced.
