摘要: 随着汽车拥有量的不断增加,公交站点对城市交通的影响日益突出, 对公交起迄点的研究,有助于公交站点的最优化布置,减少公交起迄点对道路交通的影响,提高公交起迄点路段的行车效率. 在Nagel-Schreckenberg交通流模型的基础上,采用双车道快车优先换道规则和开放边界条件,通过计算机模拟了公交车起讫站点车辆进出对城市双向四车道混合交通流的影响. 通过研究和分析发车时间间隔、车道注入概率和公交起迄站点位置对道路通行能力的影响,给出了比较合理的发车频率和公交起讫站点的位置,为改善城市道路交通和管理提供参考.

Abstract: With the increasing of cars, the influences of bus stops on urban transportation have become increasingly prominent. The researches about the origin-destination of public transportation will help to optimize layout of bus stops, reduce the influences of origin-destination of public transportation on the traffic, and improve the traffic efficiency of bus station road. In this paper, basing on the nagel-schreckenberg models of traffic flow and using the two-lane aggressive lane-changing rule, the influence of the origin-destination of the public transportation on the urban bidirectional four-lane mixed traffic flow is simulated with the open boundary conditions. Taking the departure time interval, the inject probability and the location of the origin-destination of the public transportation. We get the reasonable value of the bus departure frequency and the location of public transportation, which can offer a practical reference to the improvement for the urban road traffic and the traffic management.

Key words: mixed traffic flow, the origin-destination of public transportation, computer simulation, cellular automata model(CA), aggressive lane-changing
