基于三角模糊数的综合评价法在互通立交方案选取中的应用

随着城市的发展,城市道路在不断增加,互通立交成为解决城市交通混乱、道路相互交叉的一种重要手段.文中通过对佛山市三眼桥地段交通状况的分析,构建了三眼桥互通方案评价的指标体系,运用基于三角模糊数的综合评价方法对设计方案进行评价选择,为最优方案的最终决策提供了科学依据,同时也论证了其在多目标决策问题中的优越性.

Application of Triangular Module in Fuzzy Synthetic Judgment on the Decision of Interchange Plan

With the development of city,urban roads become more and more,and many roads intersect together.The cloverleaf junction becomes a viable solution of disordered and heavy traffic as well as intersected roads.Based on the investigation of traffic condition in the area of Sanyanqiao,an indicator system of cloverleaf alternative evaluation is built.FAHP is used to decide the best blue print of cloverleaf junction,according to the transportation evacuation of the area of Sanyanqiao in the city of Foshan.It provides scientific basis for final decision making and demonstrates the superiority of FAHP when solving multi aim questions.
