换乘交通枢纽行人设施布局仿真评价研究

换乘交通枢纽是城市交通转换出行方式关键节点,其交通设施布局直接影响乘客换乘效率,因此,对枢纽行人设施布局在设计阶段进行“事先”评价并进行优化是当前城市交通面临的问题.文中在分析行人交通需求方案与设施布局方案的基础上,采用交叉法设计仿真方案；将换乘矩阵转化为行人步行起讫点OD,以最短路为行人路径选择原则,将换乘矩阵分配枢纽行人路径上；以Legion行人模拟软件作为仿真软件,仿真行人设施仿真方案；在建立行人设施布局方案初步筛选原则的基础上,选择换乘总时间为评价指标比选设施布局方案.以宋家庄换乘交通枢纽设计方案为例,选择了设置中部自动扶梯的行人设施布局方案,其换乘总时间比不设置要减少34 h.

Simulation Evaluation on Pedestrian Facility Layouts of Transfer Station

Transfer station is an important place to switch traffic modes in urban cities.Pedestrian facilities layouts have direct impact on the transfer traffic efficiency.Thus,how to evaluate and optimize pedestrian facilities layouts in design phase is a current problem that urban cities face.Based on analyzing the layout of facilities and traffic demand programs,the simulation programs are designed by sub-crossing method.Transfer demands are assigned to the shortest route,which is the principle of the pedestrian route choice.Legion pedestrian simulation software is adopted to simulate pedestrian facilities layout programs.Based on establishing the selection principles of pedestrian facilities layout programs,the total transfer time is used to evaluate and choose the best layout program.Finally,Songjiazhuang Station is taken as an example.After simulation results are compared,the program with the central escalator is chosen.The total transfer time is 34 hours less than the program without it.
