Abstract: As the rapid economic development, the contradiction between the rapidly increasing traffic demand in south of Jiangsu province and the limited land resource is getting more and more obvious. Under the circumstance, in order to play the overall efficiency of the integrated transportation system in south of Jiangsu, based on computing automatic controlling calculating strategy of rolling optimization method, virtual rolling optimization strategy is proposed for integrated transportation structural configuration. By dynamic procedure of rolling optimization, to guarantee the best configuration of transportation pattern and route flow. The balance between supply and demand to ensure the best structure configuration of integrated transportation. Using Shanghai-Nanjing corridor as an example, based on corridor development analysis and forecasting future traffic demand, to analyze the character of integrated transportation supply and demand, to propose structure optimization strategy. Research and discussion has been done for the basic ideas and strategy of integrated transportation corridor structural optimization, to provide some reference for building more reasonable integrated transportation network layout in south of Jiangsu province.

Key words: integrated transportation;integrated transport structure;integrated transport demand forecast;integrated transportation corridor, virtual rolling optimization

摘要： 随着社会经济的高速发展，江苏省苏南地区持续快速增长的交通需求与十分有限的土地资源之间的矛盾越来越突出. 在此背景下，为了充分发挥苏南地区综合运输体系的整体效能，本文借鉴计算机自动控制算法中的滚动优化策略，提出了综合运输结构配置的虚拟滚动优化法. 通过动态的滚动优化流程，保证各运输方式及路径流量分配最优，在供需适应的基础上，确定综合运输结构的最优配置. 以沪宁通道为例，在通道发展现状分析和未来交通需求预测的基础上，分析苏南综合交通供求特性，提出结构优化方案. 本文探讨的综合运输通道结构优化的基本思路、方法，可为苏南地区构建更合理的综合运输网络布局提供一定参考.
