文章建立交通方式划分和交通分配组合模型,分析了小汽车,地铁和停车换乘之间的方式划分和路径选择。模型假设出行者出行方式决策分为两阶段,并选取停车换乘阶段的交通阻抗及交通需求作为关键影响因子,重点研究基于地铁的停车换乘系统的网络均衡问题。在算例分析中,对设置了停车换乘系统的交通网络进行了网络配流,并与不设换乘系统的网络进行对比,结果显示:前者可以有效提高公共交通的总体使用比例,降低道路拥堵。通过对换乘阶段交通阻抗、交通需求的敏感性分析发现:提高停车场站的容量,减低换乘阶段的阻抗,可以有效提高换乘方式的使用量;随着交通需求的增加,停车换乘的使用率迅速增加,表明停车换乘在交通需求较大的城市有重要意义。
This paper establishes a combination of traffic modes and traffic distribution models, and analyzes the ways of division and route selection between cars, subways and parking lots. The model assumes that the mode of travel decision of travelers is divided into two stages and the traffic impedance and traffic demand in parking and transfer stages are selected as the key impact factors. The problem of network equilibrium in parking and transfer system based on subway is mainly studied. In the case study, the network traffic distribution network with parking and transfer system is set up and compared with the network without transfer system. The results show that the former can effectively improve the overall proportion of public transportation and reduce the traffic congestion . Through the sensitivity analysis of traffic resistance and traffic demand during the transfer phase, it is found that increasing the capacity of parking lots and reducing the impedance of transfer stages can effectively increase the usage of transfer modes. With the increase of traffic demand, parking transfers The rapid increase in the use of that parking and transfer in cities with greater traffic demand is of great significance.
