道路交叉口位于轨道交通和常规公交最为常见的空间重叠区域，对换乘的安全性和高效性均会产生很大的影响。本文通过对轨道交通出入口客流换乘方式比例分析和常规公交停靠站位置比选得到交叉口处的客流换乘规律，采用主成分分析法对既有公交站优化设计的影响因素进行了研究，同时结合客流换乘规律建立了交叉口处轨道交通与常规公交的换乘模型，并给出了模型求解的方法。研究结果表明：在满足最大排队长度的条件下，行人过街次数以及交叉口的延误时间和行人的交通换乘存在着线性对应关系，通过构建换乘模型，求解出走行距离最短的方案，有利于提高交叉口处轨道交通与常规公交的换乘效率。%Road intersection located at rail transportation and conventional public transit is the most common overlapping region of space, it will produce great influence on the safety and the efficiency of transfer. Based on the entrance transfer mode proportion analysis of the passenger flow and the conventional bus stop location comparison, the passenger transfer law was obtained. By studying the effect factors of the optimization design of a bus station with principal component analysis and combining with the transfer model of passengers, a transfer model was established for the intersection of rail transit and public bus, and the method to solve the model was given. The research results show that: in the condition of satisfying the maximum queue length, the number of pedestrian crossing, intersection delay time and pedestrian traffic transfer exist linear relationship. It is helpful to construct the transfer model and to solve the shortest distance for improving the transfer efficiency of the intersection at the rail and bus transits.
