本文提出了关于交通运输与土地利用的综合模型的连续最优化及敏感性分析的基本框架。考虑外生交通费用的土地利用模型的敏感性分析和考虑弹性需求的交通运输网络的敏感性分析过程本是相互独立的，本文将两者结合为一个综合模型的敏感性分析。将这种敏感性分析方法用于土地利用方案设计和交通运输政策制定的最优化，可以使一定的社会剩余函数最大化。最后，本文以一个包含拥挤交通网络子模型的住宅分布模型为例对所提出方法进行进一步说明。

CONTINUOUS OPTIMIZATION METHOD FOR INTEGRATED LAND USE/TRANSPORT MODELS

A basic framework for the sensitivity analysis and continuous optimization of integrated land use/transportation model is proposed in this paper.It is shown that separate sensitivity analysis procedures for a land use model with exogenous travel costs and a transportation network with elastic demand can be combined to get a sensitivity analysis procedure for the integrated model.Sensitivity analysis based techniques can then be used for the optimal design of land use plans and transportation policies so that certain social surplus functions are optimized.The proposed method is illustrated with a residential location model with a congestible transport network sub-model.
