摘要
在一次出行过程中,经常会使用停车-换乘方式,即出行的前一部分采用私家车方式,途中停车,再换乘其他交通方式到达目的地。在停车-换乘出行方式下,人们除了选择路径,还要选择换乘站点。利用离散选择理论中的层次Log it结构模型,研究城市交通网络中的停车-换乘行为,定义多模式下停车-换乘出行的混合随机均衡分配条件,建立与之等价的数学规划模型,设计模型的求解算法,并用一算例分析算法的收敛性能和模型参数及公交票价对解的灵敏度。
Many commuters in modern cities take their travels to reach destinations by using park＇n ride mode, where the first part of the trip is taken by private car and the remainder is completed by taking transit modes. This commuting mode, also called combined one, requires people to choose transfer points besides deciding routes. This paper employs the nested logit model in discrete choice theory to study the park＇n ride behaviors in urban transportation networks. A mathematical programming model is established, which is equivalent to the mixed stochastic network equilibrium conditions. An algorithm for solving the model is proposed and validated by a numerical example.
