针对我国日益严重的城市道路交通拥堵问题，为缓解城市中心区交通压力，停车换乘服务作为一种有效的交通模式引入到许多城市.本文研究了在拥挤交通走廊上停车换乘系统的平衡问题.在私家车和公交车共处同一道路的综合运输系统中，出行者有三种出行模式——私家车出行模式、公交出行模式和私家车—公交换乘模式.基于这三种模式供给和需求方面的深度分析，提出了在连续走廊上出行者模式选择均衡问题，并将此问题等价转化为一个变分不等式问题.分析探讨了连续均衡模型解的性质，并通过建立公共管理模型，对停车换乘地点进行了优化.最后，通过数值算例说明了所提出模型的适用性.

Modeling Park-and-Ride System Equilibrium Problems in a Linear Monocentric City

Aiming at increasingly serious urban road traffic congestion problem, park and ride service system has been introduced in many cities as an effective traffic mode to alleviate the urban central district traffic pressure. This paper investigates the P&;R system equilibrium issues in a congested highway corridor. In the integrated transportation system, private cars and buses share the same roadway along the corridor. Travelers have three travel modes, private car, bus and auto bus. On the basis of an in depth analysis of the demand and supply sides of the three travel modes in the integrated transportation system, the mode choice equilibrium of travelers along the continuum corridor is presented and formulated as an equivalent variational inequality problem. The solution properties of the continuum equilibrium formulation are analytically explored, and a modal is proposed on basis of public regulatory. In the public regulatory model, the location of P &; R facility is simultaneously optimized. Finally, an illustrative example is given to demonstrate the application of the proposed models.
