【摘要】：为了降低交叉口处公交停靠站对周边道路交通流的影响,给实际交叉口及其周边附属设施的规划设计提供参考,在交通流元胞自动机模型研究的基础上,分别分析公交车停靠、运行、换道行为及交叉口饱和度、绿信比、信号周期等交叉口参数,结合元胞自动机模型的设置原理,构建车辆、交叉口平面、停靠站等子模型,进而得到一种新型交叉口公交停靠站选址模型。使用MATLAB软件对建立的模型进行仿真,将受到公交停靠影响的社会车辆行车时间作为仿真的输出结果,并将输出结果与实际调查情况进行对比,验证模型的可靠性。结果表明:建立的模型符合实际,能够反映出公交车辆在交叉口处的停靠情况;公交停靠站对交通的影响程度与停靠站距交叉口的距离呈现W形的变化趋势;港湾式停靠站对周边机动车及交叉口运行的影响程度比直线式停靠站小;上游停靠站的推荐设置区间为距交叉口70~110m的区域,下游的推荐区间为距交叉口60~90m的区域;不同饱和度下的停靠站设置区间差别较大,在实际应用时需要进行精细化分析。
[Abstract]:In order to reduce the intersection of bus stop on the surrounding road traffic flow, to provide reference for the planning and design of the actual intersection and its surrounding ancillary facilities, based on cellular automaton model of traffic flow, respectively, analysis of bus stops, running, lane changing behavior and intersection saturation, green ratio, signal cycle etc. the intersection of parameters, the construction of vehicles combined with the setting principle, cellular automaton model, plane intersection, stop sub model, and a new bus stop. The intersection location model of building the simulation model using MATLAB software, will be affected by the bus stop social vehicles travel time as the output simulation results, and the output results are compared with the actual investigation, verify the reliability of the model. The result shows that the model can reflect the actual public traffic vehicles at the intersection Stop at the bus stop; the degree of impact on traffic and stop distance shows a W shape change trend; harbor2shaped bus stop on the degree of influence around the vehicle and intersection operation than the straight line stop; stop setting upstream recommended interval from the intersection region of 70~110m the recommended interval downstream from the intersection of 60~90m area; different saturation station set interval difference, in the practical application, the need for meticulous analysis.
