摘要
基于综合运输通道内用户出行需求和供应特点,对传统的通道结构配置方法存在的不足进行了分析.从用户效应出发对综合运输通道结构进行了界定,建立了通道内运输方式的多维Logit选择函数,提出了综合运输通道结构合理配置方法,并运用极大似然法给出了模型的有关参数.最后,通过西南出海通道(成渝段)的实例验证了模型的可行性.
The limitations of the traditional methods of corridor structure configuration were analyzed based on the characters of demand and supply of users in a comprehensive transportation corridor. The corridor structure was defined from point of view of users, a multidimensional Logit function of transportation method selecting was given, and a method of the reasonable structure configuration of a comprehensive transportation corridor was proposed. In addition, the maximum likelihood estimation was applied to determine the related parameters. At last, the feasibility of the proposed method was proved by a practical example, Chengdu to Chongqing section on the corridor to the sea for the Southwest China.
