Effects of Bottlenecks in Vehicle Traffic

by Syohei Yamamoto, Yasuhiro Hieida & Shin-ichi Tadaki arXiv.org E-print Archive, 10 Apr 2006 Traffic congestion is usually observed at the upper streams of bottlenecks like tunnels. Congestion appears as stop-and-go waves and high density uniform flow. We perform simulations of traffic flow with a bottleneck using the coupled map optimal velocity model. The bottleneck is expressed as a road segment with speed reduction. The emergence of stop-and-go waves depends on the speed reduction in the bottleneck. A phenomenological theory of bottleneck effects is constructed. Read more
