上海市公路网OD推算方法张金发1 林航飞1 王维凤2 (同济大学交通工程系1 上海市公路管理处2) 摘要:本文介绍了在上海市公路OD大调查的基础上进行OD推算的过程。分别利用“最短路径剩余法”以及双层规划模型的OD反推方法解决了各单点 OD调查中的“串并联”问题。最后对推算出的上海市公路网OD分布进行检验。 关键词:OD矩阵;上海公路;最短路径剩余法;OD推算
OD-matrix Deduction Method of Highway Network in ShanghaiZHANG Jin-fa1 LIN Hang-fei1 WANG Wei-feng2 Abstract:The procedure of OD-matrix deduction is introduced based on the shanghai highway’s OD survey. “The shortest path surplus method” and OD inverse deduction method are used solving the “Series and Parallel Connection” problems in OD-matrix deduction. The OD inverse deduction method is based on VISSUM,a powerful macro-simulation software. At last, the result is checked with some indexes. Key words:OD matrix;Shanghai highway;the shortest path surplus method;OD deduction
