| 摘 要： | OD矩阵推算和交通分配的结果是否符合实际,受所用分配模型、分配率P是否符合实际、路段流量是否经过守恒处理等因素影响。不同的分配参数会对分配率P产生不同的影响,从而影响分配结果,最终影响反推。采用对路段选择率和OD量同时推算的方法,尽量避免由于取值问题带来的误差,从而使推算结果更符合实际。

| Abstract: | There are many factors that influence OD matrix and traffic assignment,for example,dispersion model,link choice proportions,and so on.Link choice proportions in a network change with traffic conditions.Results from a numerical study using a hypothetical network have shown that a model allowing to be estimated simultaneously with an OD matrix form the observed data performs better than the model with a fixed predetermined. |

| Keywords: | dispersion parameter traffic counts OD matrix link choice proportion |
