基于FCM算法的高铁建设对高速公路的影响研究

文章针对高铁建设对高速公路的影响问题,首先,以北京和天津为研究对象,选取旅客样本特征、高铁建成前后人们出行行为特征、人们高铁选择偏好和意愿特征的聚类中心。其次,结合主客观赋权法,对各指标进行定量赋权。再次,用FCM算法计算出高铁建成前后人们的选择偏好和意愿特征的相关指数。最后,用可视化工具分析北京、天津的高铁资源对高速公路的缓压程度。得出结论:高铁的开通会使得高速公路的车辆有所减少,并且成效显著。

Study on the influence of high-speed railway construction on expressway based on FCM algorithm

Aiming at the impact of high-speed railway construction on expressways,this paper firstly takes Beijing and Tianjin as the research objects,and selects a cluster center with the characteristics of passenger samples,people’s travel behavior before and after the construction of high-speed railway as the characteristics,and people’s preference and willingness of high-speed railway selection.Secondly,combining subjective and objective weighting method,quantitative weighting is carried out on each index.Then,FCM algorithm is used to calculate the correlation index of people’s choice preference and willingness characteristics before and after the construction of high-speed railway.Finally,visual tools are used to analyze the slow pressure of high-speed railway resources in Beijing and Tianjin on expressways.It is concluded that the opening of high-speed railway will reduce the number of vehicles on the expressway,and the effect is remarkable.
