基于灰色加权关联度的市域通勤轨道线网方案优选研究

摘要

With the development of cities and mega cities,the metropolis commuter traffic volume is getting much larger, so it is important to plan the metropolis commuter rail transit. Based on an analysis of the characteristics of metropolis commuter,the grey weight relation model is put forward to evaluate the planning. The index system for evaluating the metropolis commuter rail transit is buithe Entropy Method is applied to decide the weight of each index. Finally an example is given to apply the method to optimize three preset schemes and to decide which is the best one.%随着大城市、特大城市不断发展,市域通勤交通流量日增,使市域通勤轨道交通线网合理规划的重要性不容忽视.结合市域通勤轨道交通的特点,提出“灰色加权联度”的评价优选模型,建立市域通勤轨道交通线网评价方案的指标体系,采用“熵值法”确定各个指标的权重,对各个线网规划的预选模型进行综合评价,并结合案例对某大城市的3个市域通勤轨道交通线网预选方案进行分析,选出最佳方案.
