摘要
交通网络中 OD矩阵的推算曾一度成为交通规划界的热点 ,国内外不少学者也提出了一些计算模型和求解方法 .在此基础上 ,针对常规求解方法的不足 ,提出了应用神经网络来进行 OD矩阵的推算 .最后通过实例 ,分析了此方法的精度 。
It once became popular to estimate OD matrices in the field of traffic planning。Some estimating models and solving methods are proposed at home and abroad。In order to overcome the imperfect of these custom algorithms, this paper presented a new way to apply artificial neural network to estimating OD matrices。At last, this method proves to be feasible in theory and in practice by analyzing the precision of a practical example.
