Study on the Mixing Traffic in a Single-Lane Roundabout with Open Boundary Condition

Abstract:

Based on the Nagel-Schrekenberg (NaSch) model, a cellular automation model is proposed to describe the mixing traffic flow in a single-lane roundabout with open boundary condition. In this model, the impact of the injection probability and the mixed proportion coefficient on the mixed traffic flow is emphatically studied. Simulation results indicate that the injection probability can change the system density, velocity and flow in a certain range for a constant mixed proportion coefficient. Moreover, for a fixed injection probability, when the injection probability is lower than the critical level, the system average velocity will be more affected by the mixed proportion coefficient, By contrast, the system flow will not change by the mixed proportion coefficient; When the injection probability is higher than the critical level, the mixed proportion coefficient can only change the system density, average velocity and flow in a small range.
