摘　　要：基于社会可持续性、经济可持续性和环境可持续性3个方面的交通可持续性,以交通系统的社会效率最大化和交通系统内部成本以及环境影响最小化为约束,构建城市客运交通结构优化模型并进行优化,并利用多目标规划中的理想点法求解模型。以成都市为例,验证了模型的可行性与正确性,优化后的客运结构体现了城市可持续交通的发展目标。Based on the social sustainability , economical sustainability and environmental sustainability , the optimized model of the urban passenger transportation structure is established by maximizing the social efficiency and minimizing the internal cost of transportation system and its environmental influence .In addition, the model is calculated by using the ideal point of the multiple plans .In the article, the city of Chengdu is used as an example to verify the practicability and correctness of the model and the optimized passenger structure reflects the sustainable development goal of the urban transportation .
