摘要
为建立更科学、出行舒适的交通分配模型,探讨了路段舒适性的定义与量化,建立了舒适性出行偏好的网络均衡模型。将出行者划分为快捷性偏好和舒适性偏好两种类型,假设网络中两种出行者同时存在,构建与混合均衡条件等价的多用户混合均衡模型,并对该混合均衡模型的MSA求解算法进行设计。研究结果表明:舒适性路径选择行为形成的均衡流分布模式与快捷性的均衡流分布模式不同,两种路径选择行为导致的网络均衡状态均为混合均衡状态的特例。舒适性的交通分配模型可以弥补传统交通分配模型的不足,所预测的网络交通流分布形态也更准确,可为交通管控方案提供新的思路。
In order to establish a scientific traffic assignment model for the travel comfort,the network equilibrium model of comfort travel preference was established by exploring the definition and quantification of link comfort. Travelers were divided into two types of speedy preference and comfort preference. The multi-user mixed equilibrium model equivalent to the mixed equilibrium condition was established,assuming the simultaneous existence of two types of travelers in the network. The MSA solution algorithm for this mixed equilibrium model was then designed. The results show that the equilibrium flow distribution pattern formed by the comfort route selection behavior is obviously different from that of the speedy equilibrium flow distribution pattern. The network equilibrium state caused by the two route selection behaviors is a particular case of mixed equilibrium. The establishment of the comfort traffic assignment model to describe the route selection behavior of travelers can make up for the shortage of the traditional traffic assignment model. It can also accurately predict the traffic flow distribution pattern of the network,providing new idea for the traffic management scheme.
