May 9: "Dynamic Traffic Assignment and the Route-Link Consistency Issue" Presented by Hillel Bar Gera Senior Lecturer, Ben-Gurion University of the Negev, Beer-Sheva, Israel .(PDF of announcement flyer).
Abstract: Macroscopic (continuous-flow) dynamic traffic assignment model can be divided into two major families. The first family, including the LWR (kinematic waves) and cell-transmission models for example, emphasizes local driver behavior and focuses on the resulting link performance. The second family emphasizes the propagation of flows along route trajectories. The potential issue of inconsistency between the two considerations is often overlooked. In this seminar I will use examples to show the route-link consistency issue in dynamic traffic models, as well as a possible solution for this problem. I will then present an implementation of the solution in a dynamic network loading model that integrates the popular LWR approach with route trajectories. Time permitting, new results on dynamic route choice will conclude the presentation.
Hillel Bar-Gera is a tenured Senior Lecturer of Industrial Engineering and Management at Ben-Gurion University of the Negev, Beer-Sheva, Israel. His Ph.D. thesis on the origin-based assignment algorithm won the 2000 dissertation award for best Ph.D. thesis in transportation from the Transportation Science Section of INFORMS. Hillel Bar-Gera has been a faculty member at Ben-Gurion University since 2001. He received his B.Sc. in Mathematics, Physics and Computer Science as well as his M.Sc. in Mathematics from the Hebrew University, Jerusalem, Israel. He received his Ph.D. in Civil and Materials Engineering from the University of Illinois at Chicago. Bar-Gera serves as a member of the Intelligent Transportation Systems committee of the Transportation Research Board, and as an associate editor of the journal of Networks and Spatial Economics.
