水运OD矩阵的推算模型研究

Research on the Computative Models of Waterborne OD Matrix

交通OD矩阵是交通量预测的基础,但由于资料调查工作量大且精度难以控制,水运OD矩阵往往难以通过调查直接得到。鉴于此,基于对现有OD矩阵推算模型的研究与分析,并结合水上运输及其运输量调查资料的特性,提出了一种利用水运港口吞吐量和水运客货运平均运距推算水运OD矩阵的计算模型,由此可推算得到水运OD矩阵,供相关分析研究之用。

OD matrix is the foundation of traffic volume forecasting, but it is very difficult to obtain the waterborne OD matrix because of a mass of imprecise survey data. In order to obtain the water-borne OD matrix, port throughput and the average of carrying distance are used for new computative models of waterborne OD matrix, on the basis of the analyses of the shortcomings of traditional models and the speciality of water carriage.
