This paper presents a cellular automaton traffic flow
model with an open boundary condition to describe the traffic flow at
a roundabout crossing with an inner roundabout lane and an outer
roundabout lane. The simulation results show that the boundary
condition, bottlenecks and the self-organization affect the traffic
flow at the roundabout crossing. Because of the effect of
bottlenecks, jams easily appear on the inner roundabout lane. To
improve the capacity of the roundabout system, proper values of the
enter probability α and the out probability $\beta $ can be
chosen. 相似文献

A main-road cellular automata traffic flow model on two dimensions is presented based on the Biham-Middleton-Levine traffic model. Its evolution equations are given and the self-organization and organization cooperation phenomena in this model are also studied by using computer simulation. 相似文献

A lattice-gas model of biased-random walkers is used to simulate the escaping pedestrian flow under the open boundary condition in corridor. Given that the total number of people is unchanging, we have studied the evolution of pedestrian flow by varying parameters of system size. Relationships between parameters of system size and the transition time are discussed in this paper. Scaling behaviour is found as follows: the transition time t_c scales as t_c∝W^{-0.85±0.04}, and t_c∝D, where W is the width of corridor, and D is the strength of drift. However, the other parameters are found to have little influence on the transition time. 相似文献
