## PIMS/AMI Seminar: Nonlinear waves in traffic flow

• Date: 04/06/2010
Lecturer(s):
Morris Flynn, Department of Mechanical Engineering University of Alberta
Location:

University of Alberta

Description:

Continuum traffic theories whereby individual vehicles are collectively modeled have enjoyed a rich history since their popularization by M.J. Lighthill and G.B. Whitham. These models are able to elucidate the dynamics of phantom jams,'' transient blockages that arise without obstructions. Notwithstanding this venerated record, the possibility of self-sustained disturbances consisting of a shock matched to a transonic flow has received inadequate attention despite recent experimental evidence that such jamitons'' are ubiquitous. By drawing a remarkable analogy between jamitons and detonation waves, I herein identify a novel class of traveling wave solutions pertinent to heavy traffic flow. This work is done in collaboration with R.R. Rosales, J.-C. Nave, B. Seibold and A.R. Kasimov.
