摘　　要：针对传统的城市客运交通结构规划中的不足及已有城市交通结构优化模型过于侧重城市交通供给的问题,建立了以出行者广义费用最小为目标的城市结构优化模型。该模型通过从出行特性角度出发,在考虑可持续发展的基础之上,把城市交通需求、资源、能源、环境作为约束条件,较好的体现了当今城市交通的发展态势,为城市客运交通结构优化提供理论支撑。Aimed at the deficiency of traditional urban passenger traffic structure planning and the problem of relying too much oll lhe urban traffic supply in The existing urban traffic stnwture optimization model, this paper builds up an urban structure optimization model, lhe purpose of which is to minimize the traveler generalized cost. From the angle of the travel eharacterislics and considering the basis of sustainable developmenl, the model lakes !he urban traffic demand, resourees, energy and environmenl as a constraint condition to reflect better the development trend of urban traffic, providing theoretical support for urlmn passenger traffic stnlelure optimization.
