摘　　要：简述了OD矩阵反推法的优缺点,对TransCAD平台下的多种交通量分配方法进行了介绍,构建了基于TransCAD平台的OD矩阵反推模型,经实际项目验证,指出运用"塔桥法"对模拟路网的交叉口进行优化处理,可提高OD矩阵法反推模型的精度。The paper indicates the advantages and disadvantages of OD inverse deduction matrix method, introduces many traffic distribution methods under TransCAD platform, builds up the model for the OD inverse deduction matrix method based on TransCAD platform, proves by the programs that the adoption of the ＂bridging method＂ can undertake the optimal treatment of the crossings of the simulated road network, so as to improve the accuracy of the OD inverse deduction matrix method.
