CTS Fellow Daniel Ayala will present a seminar entitled "Randomized Route Guidance for Car Navigation Systems" on Monday, February 8th at 4:00 p.m. in Room 1000 SEO
Current car navigation systems guide users to their destinations by taking them through a computed shortest path on the road network. This is less than optimal routing when the road is congested. In a system where vehicles follow the advice of the car navigation system, if all users going to a similar destination are given the same shortest path, this path will become saturated and will cease to be the shortest path. This problem can be viewed as vehicles competing for shortest routes to their destinations. In addition, it can be viewed as a resource allocation problem where the resource being allocated is a route. The traffic assignment problem deals with assigning vehicles to routes optimally based on some given criteria. In this work we propose a distributed algorithm for car navigation devices that uses a randomization scheme to perform a System Optimal Dynamic Traffic Assignment. We also propose a distributed approximation algorithm for performing an assignment without having to compute the optimal traffic assignment by using real-time travel time data on the road links. This talk will be an overview of our current research, which is still a work in progress.
Daniel Ayala is a 3rd year PhD. student and Computational Transportation Science NSF-IGERT fellow in the Computer Science Department at UIC. His current research centers around routing and information management for intelligent transportation systems. Daniel's primary advisor is Dr. Ouri Wolfson and his secondary advisor is Dr. Jane Lin.
