摘　　要：城市群轨道交通客流预测多采用综合线网分配预测法,为了提高预测法精度,准确地描述城市群中各种公共交通方式之间的合作竞争关系,在预测时需要考虑竞争方式的运营组织。讨论了基于运营组织的城市群轨道交通客流预测分配阶段应用TransCAD解决预测的整体思路与方案,阐述了其操作步骤、各种层的建立、相关表的建立及设置、相关属性设置、分配结果处理及需注意的事项,并引入AutoCAD辅助建立基层线网层及小区层。The forecast method of synthesis network assignment usually uses the passenger flow forecast of metropolitan agglomeration. In order to improve the precision and accurately describe the cooperation and competition relationship among public transportation modes in metropolitan agglomeration, the operation organization of competition transportation modes should be considered during the forecast. The overall idea and the plan of applying the TransCAD to solving problems on the transit assignment stage of the passenger flow forecast of metropolitan agglomeration were elaborated on the basis of operation organization. Meanwhile, the sequence of operation, each type of layer establishment, pertinent table establishment and the settings, pertinent attribute settings, assignment result disposal, and the item that should been paid attention to were also illustrated. At last, the method of introducing AutoCAD to help to establish the basic line layer and area layer was introduced.
