为支持可持续发展交通运输系统规划的理论体系的创立,引入交通容量、环境容量和方式能耗的概念,提出基于能源消耗的城市交通结构优化的思路、模型与方法,并进行了应用实例研究。该模型融入了影响城市交通结构的各种因素,使其最优解既能满足经济发展带来的交通需求,又能使交通的环境影响和资源消耗最小化,从而为可持续发展的交通运输系统的规划提供了可行的理论与方法。 In order to support the establishment of the theoretical system of transportation system planning for sustainable development, the concepts of traffic capacity, environmental capacity and energy consumption are introduced, and the ideas, models and methods of urban traffic structure optimization based on energy consumption are put forward. . The model incorporates various factors that affect the urban traffic structure so that the optimal solution can not only meet the traffic demand brought by economic development but also minimize the environmental impact and resource consumption of transportation so as to provide a sustainable development mode of transportation System planning provides a viable theory and method.
