摘　　要：在人行天桥的选址中,对人流和车流的科学预测是选址及规模确定的关键。针对规划道路中人行天桥选址项目独有的特点,论述人行天桥选址的原则;结合晋江人行天桥项目,介绍TransCAD在行人交通预测中的应用,并引进HCM评价法对行人服务水平进行分级和评价。研究表明:应用TransCAD的预测结果不仅能够为人行天桥的选址及规模论证提供科学依据,引进OD反推方法、HCM评价法、双约束模型还能够为同类人行天桥选址项目的设计提供参考和借鉴。In the site selection of pedestrian bridge,the scientific prediction of pedestrian flow and vehicle flow is the key to determine the site selection and scale of pedestrian bridge.According to the unique characteristics of the pedestrian bridge site selection project in the planned road,the principle of site selection of pedestrian bridge is discussed.Combined with the Jinjiang Pedestrian Bridge Project,the application of TransCAD in pedestrian traffic prediction is introduced,and the HCM evaluation method is introduced to grade and evaluate the pedestrian service level.The research shows that the prediction results can provide the scientific basis for the site selection and scale demonstration of pedestrian bridges,and the OD inverse method,HCM evaluation method and double-constraint model can also provide the reference for the design of site selection projects of similar pedestrian bridges.
