运输通道结构配置中的客流量分配模型及算法

Model and Algorithm Research on Solving Passenger Flow Allocation in Transport Corridor

采用动态交通分配的思想,描述运输通道内各运输方式交通量的时间空间演化特征,构建出基于网络均衡的客流分配模型,该模型克服了静态的、基于多元Logit随机效用的选择概率模型的不足,可对通道内各运输方式分担的运量和合理数量进行更为客观、符合实际的求解.文中还对该模型的求解算法和程序进行了研究,最后运用实例验证了该模型和程序的可行性.

A dynamic distributing traffic idea is introduced into this paper to describe the evolution characteristics of volume carrying by each transport mode. And the passenger flow allocation model on the basis of the network balance is built by overcoming the disadvantaging of previous models, which helps the allocation of each traffic mode to be more reasonable. Some researches are also conducted on the algorithm and program of the model, and an example is presented to validate the feasibility of the model and the program.
