摘　　要：从环境承载力的角度出发,将环境保护与道路网络改扩建联系起来,定量研究了环境承载力约束下的交通网络设计问题,构建了基于环境承载力的连续型交通网络设计双层规划模型。其中,上层模型目标为系统总时间消耗最小、方案总投资费用最小,并以区域道路交通系统大气环境容量限值、路段声环境限值作为约束;下层模型为固定需求的用户平衡分配模型。根据模型的结构特点,采用改进的遗传算法对模型进行求解,并在Matlab平台上开发了相应的算法程序。最后通过实例验证了模型的有效性。From the perspective of the capability of environment,Connecting environmental protection together with road network expansion,this paper makes a quantitative study on the transportation network design,and builds a Bi-level programming model of continuous transportation network regarding the environmental carrying capacity.Among this continuous transportation network the top level of the model gets a minimum time-consuming and minimum investment,it is designed with the constraints of the atmospheric capacity limit and the sound environmental capacity limit in the regional road transport system;the under level is a user balance model with fixed allocation.Regarding the characteristics of the model＇s structure,it is implemented with the improved genetic algorithm and programmed on Matlab platform.The model＇s validity is verified through instances and can be referenced in actual projects.
