摘　　要：文中建立了开口边界下的混合交通流的共线公交线路模型.通过仿真模拟,探讨了小汽车进入车道概率及共线区间的长度对公交运营状态的影响,分别绘制了四种场景下的相位图,它由四个区域组成,包括均匀区域、能力不足区域、串车区域和严重拥堵区域.通过研究小汽车对公交系统的影响,发现在小汽车进入车道数量较大时,公交的运行速度降低,串车情况有所缓解.同时,通过对共线区段的长度研究,发现在共线区段较长时,更容易导致公交的串车拥堵.A common line bus line model of mixed traffic flow under open boundary was established.Through simulation,this paper discussed the influence of the probability of cars entering the lane and the length of collinear section on the bus operation state.The phase diagrams of four scenes were drawn,including four areas:uniform area,insufficient capacity area,cross-train area and serious con-gestion area.By studying the influence of cars on the public transport system,it is found that when the number of cars entering the lanes is large,the running speed of public transport decreases and the situation of cross-train is alleviated.Meanwhile,through the study of the length of the collinear sec tion,it is found that when the common line section is long,it is more likely to lead to bus congestion.
