进行城市干道网项目排序是为了合理利用建设资金使交通运行状况得到最大改善,真正发挥规划方案的作用.将综合定量比较法与以路网总运行时间为目标的投资优化模型相结合应用于城市干道建设项目排序中,先确定了各个规划期的项目,然后确定了近期的建设项目排序,并以咸宁市路网为例,说明了建设排序的决策过程,收到了较好的效果.这为城市干道建设项目排序工作提供了一种参考.
The sequencing of urban road network project is to make rational use of construction funds to maximize the traffic conditions and truly play the role of planning program.Combining the method of comprehensive quantitative comparison with the investment optimization model which aims at the total running time of the road network, In the sorting of the trunk road construction projects, the projects in each planning period are determined first, and then the recent construction projects sort is determined. Taking the Xianning road network as an example, the decision-making process of the construction sorting is described and the better result is obtained Urban trunk road construction projects to provide a sort of reference.
