摘要: 采用元胞自动机模型对具有公交线路的双车道混合交通系统进行建模和模拟分析. 通过绘制系统的基本图和右车道上车辆占有率分析了公交线路对双车道车流演化特性以及运行效率的影响,并针对港湾式和非港湾式两种停靠方式的优劣进行比较. 研究结果显示,系统中存在四个车流演化特性不同的密度区域;系统中公交车数量增多会导致最大流量降低;港湾式停靠站的公交线路系统对车流的影响小,系统流量大,优于非港湾式停靠站的公交线路系统.

Abstract: In this paper, a two-lane system with bus route is studied by a cellular automata model. The evolution characteristics and the operational efficiency are analyzed by plotting the fundamental diagram and the vehicle occupancy on the right lane (nearside lane). The two types of bus stops, namely, non-harbor shaped and harbor shaped, are considered, and the merits of the two types of bus stop are compared. The simulation results show that there are four density regions with different evolution dynamics of traffic flow; The maximum flow is decreased with the number of buses increasing. The bus route with harbor-shaped stop exerts less affects to the traffic flow and its maximum flow is higher than the bus route with non-harbor-shaped stop.

Key words: urban traffic, mixed traffic flow, cellular automata, bus route, two-lane
