Effect of bottleneck on route choice in two-route traffic system with real-time information

We study the traffic behavior in the case that there exists a bottleneck on a route in the two-route traffic system with real-time information. We introduce the bottleneck into the two-route dynamic model proposed by Wahle et al. When there is a bottleneck on route A, a traffic jam occurs behind the bottleneck on route A. The drivers try to avoid the congestion by the use of real-time information. We derive the dependence of the travel time and mean density on the bottleneck’s strength. We show where, when, and how the traffic jam occurs by the bottleneck. We clarify the effect of the bottleneck on the traffic behavior in the route choice. We show that the dynamic transition occurs from the oscillating jam to the stationary jam with increasing blocking probability.
