摘要在这项研究中，我们研究了城市中的住房分配和交通排放问题。住房发展模式对出行行为和相关交通排放有重大影响。我们假设一个城市有一个中央商务区，其中的道路网络被认为是足够密集，被视为一个连续体。我们建立了一个双层动态连续模型来描述住房供给、交通系统和交通相关排放之间的关系。在下层子程序中，住房分配被认为是一个同时出发时间和路线选择的动态交通用户平衡模型，在该模型中，旅行者选择满足动态用户最优原则的路线和出发时间。在上层子程序中，通过优化住房分配使总排放量最小化。采用有限体积法、投影法、逐次平均法和Frank-Wolfe法对基于非结构网格的模型进行求解。最后，通过一个城市中心商业区的算例验证了模型和算法的有效性。
Abstract In this study, we examine housing allocation and transportation emission problems in an urban city. Housing development patterns have a significant influence on travel behavior and related transportation emissions. We consider a hypothetical city with one central business district in which the road network is assumed to be sufficiently dense to be viewed as a continuum. We establish a bilevel dynamic continuum model to describe the relationships among housing provision, the transportation system, and traffic-related emissions. In the lower-level subprogram, housing allocation is considered in a simultaneous departure time and route-choice dynamic traffic user equilibrium model, in which travelers choose routes and departure times that satisfy dynamic user-optimal principles. In the upper-level subprogram, the total emissions are minimized by optimizing the housing allocation. The finite-volume method, the projection method, the method of successive averages, and the Frank–Wolfe method are applied to solve the presented model based on unstructured meshes. A numerical experiment for an urban area with one central business district is given to demonstrate the effectiveness of the model and the numerical algorithm.
