=== Seminar Abstract ===

A nonlinear car-following model of highway traffic is considered that
includes the reaction-time delay of drivers. Linear stability
investigations show that the uniform flow solution may loose its stability
via Hopf bifurcations. Studying these bifurcations by normal form
calculations reveal the possibility of bistable behaviour. Regions in
parameter space are determined by numerical continuation techniques where
the stable uniform flow co-exists with single or multiple stop-and-go
traffic jams. Detailed stability investigation of the corresponding
oscillations explains the low-dimensional dynamics of the merging and the
dispersion of traffic jams. Stochastic effects are also studied by
numerical simulation when a driver parameter is varied according to a
random walk. This is a joint work with Gabor Stepan (Budapest University
of Technology and Economics) and with Eddie Wilson and Bernd Krauskopf
(University of Bristol).
