摘要 针对基于车流到达服从标准泊松分布的并行收费站排队服务模型在交通流的时空复杂性、成本、可靠性等方面存在的不足,提出基于元胞自动机建模与仿真的串行收费站布设方式的通行能力、延误及布设个数的分析方法。研究结论表明:串行收费站的通行能力随布设个数的增加而增大,但增大幅度缓慢降低;串行收费站的车均延误以80%通行能力的流量水平为分界点,随着流量继续增大,车均延误急剧上升。给出了不同的流量水平所对应的串行收费站最佳布设个数。 The line up service model at parallel toll station, based on the traffic arrival subject to the standard Poisson distribution, has some shortages in time and space complexity, cost, reliability and other aspects. Concerning these shortcomings, this paper presents an analytical method to review the traffic capacity, delay and setting number of serial toll station which is set based on cellular automata modeling and simulation. The study results show that the traffic capacity of serial toll station is increased with its setting number but the increment is becoming slower; the critical point of average traffic delay of serial toll station is at the level of eighty percent of traffic capacity, and average traffic delay will increase sharply over this point. This paper gives the best setting number of serial toll sta- tion at different flow levels.
