摘要
交叉路口是道路的枢纽,影响道路畅通的瓶颈。本文以相邻的两个交叉路口作为研究对象,分析挖掘相邻路口之间的历史交通数据,同时构建多元线性回归的模型对两路口之间的车流量进行预测。研究结果表明,相比只考虑车流量的单因素预测基础上加入限号、天气因素能更加准确地预测未来5到15分钟的车流量。
Intersection is the key of the road, and the bottleneck of the road is affected. In this paper, we take two adjacent intersections as the research objects, and analyze the historical traffic data between adjacent intersections,while building a multiple linear regression model to predict the traffic flow between the two intersection. Research results show that compared to only consider the single factor based on the traffic flow to add a limited number, weather factors can more accurately predict the traffic flow of next 5 to 15 minutes.
