【摘要】：随着城市综合交通体系的不断发展和完善,城市出行多方式化的特征日益突出.本文在充分考虑城市多方式交通网络结构特性的基础上,构建方式及路径联合选择模型,研究多方式条件下的交通分配方法.首先,基于随机效用最大化理论构建出行方式和路径联合选择的Nested Logit(NL)模型;其次,运用路段实测交通流数据标定道路混合交通流条件下的交通阻抗函数;最后,基于构造的多方式交通网络进行多方式交通分配,分析出行量在网络上的时空分布.结果表明,本文所提出的多方式条件下的交通分配方法,能够有效地描述城市多方式交通网络条件下的出行方式和路径选择行为,以及交通出行在交通网络上的时空分布规律,对于完善城市综合交通体系具有重要意义.
[Abstract]:With the continuous development and improvement of urban comprehensive transportation system, the characteristics of multi-mode urban travel become increasingly prominent. On the basis of fully considering the characteristics of urban multi-mode traffic network structure, this paper constructs a model of joint selection of modes and paths, and studies the method of traffic assignment under multi-mode conditions. Firstly, based on the theory of stochastic utility maximization, the Nested model of travel mode and route selection is constructed. Secondly, the traffic impedance function under mixed traffic flow condition is calibrated with the measured traffic flow data. Based on the constructed multi-mode traffic network, multi-mode traffic assignment is carried out, and the spatial and temporal distribution of travel volume on the network is analyzed. The results show that the multi-mode traffic assignment method proposed in this paper can effectively describe the travel mode and path selection behavior under the condition of multi-mode urban traffic network, as well as the space-time distribution of traffic travel on the transportation network. It is of great significance to improve the urban comprehensive transportation system.
