Abstract
This paper proposes a vehicle-pedestrian cellular automata model to investigate the characteristics of the mixed traffic at a single lane roundabout. The roundabout boundary is controlled by the injecting rates α1,α2 and the extracting rate β whereas pedestrians are generated with arrival probability Pcr. The pedestrian and vehicle flux are calculated in terms of rates. Also, the phase diagrams of the system in the (α1,Pcr) and (α1,β) spaces are constructed. The results show that, the gridlock state is reached only when the pedestrians have the right of way over vehicles, while the maximum current state is reached when including a pedestrians' crossing decision rule. Likewise, we have found that the crosswalk location play a chief role in improving the dynamic characteristics of pedestrian and vehicle flux. Furthermore, it has turned out that the traffic is sensitive to the driver behavior.
