基于灰色加权关联度的区域运输通道规划方案优选研究

Evaluation of Regional Transportation Corridor Planning Based on Grey Weight Relation

随着大城市、特大城市不断发展,各大城市倾向于大力构建对外运输通道,连接周边发达区域或资源丰富的区域,因而,区域运输通道的合理规划的重要性不容忽视。本文结合区域运输通道的交通特点,提出"灰色加权关联度"的评价优选模型,建立通道规划方案的评价指标体系,采用"熵值法"确定各个指标的权重,对各个规划方案的预选模型进行综合评价,并结合案例对A城市的3个运输通道的预选方案进行分析,选出最佳方案。

With the transportations to devel joint opment of big city and mega city, the cities tend to construct the surrounding developed regions or rich resource areas. So it is very important to plan the transportation corridor. Based on analysis of the characteristics of the transportation corridor, a grey weight relation model was put forward to evaluating the planning. An index system for evaluating the metropolis commuter rail transit was built. The entropy method was applied to decide the weight of each index. And finally, an example was taken to apply the method to optimize three initial schemes and the best one was decided.
