基于改进VIKOR算法的现代有轨电车线网规划研究

近年来,我国城市不断增加的机动车保有量,引发了严重的城市交通问题,当前急需引进新的交通方式,以减少交通拥堵、改善城市环境.相比昂贵的地铁系统,现代有轨电车满足价格合理、绿色环保、方便快捷的城市要求,逐渐在各大城市推广使用.考虑到其建成后难以改动的特点,则做好线网规划方案显得尤为重要.本文以某一具体城市线网规划为背景,通过建立现代有轨电车线网方案优选的指标体系,兼顾主客观因素,运用蒙特卡洛和熵值赋权的组合赋权方法确定指标体系的权重,提出了基于改进赋权方法的VIKOR模型,对城市有轨电车线网规划方案进行优选,为现代有轨电车提供合理的线网规划方案.

Modern Tram Line Network Planning Based on the Improved Weighted VIKOR Method

In recent years, the quantity of motor vehicles in our country is increasing, which has caused serious urban traffic problems. Therefore, it is necessary to explore new ways to reduce traffic congestion and improve the urban environment. Because most of our city does not have the construction of the subway system, city planners have committed to the development of modern trams, taking into account the modern tram was built to change the characteristics of line network planning is particularly important. This paper takes a specific city network planning as the background, through the establishment of index system of modern tram line network optimization scheme, combined with Monte Carlo and entropy weighting method to determine the weight of the index system, put forward the improvement method of weighting VIKOR model is optimized based on the other case, the use of Matlab programming model of the optimal results the measured results, and the main line network scheme comparison, verify the feasibility and effectiveness of the method, for the modern tram line network planning scheme.
