摘要
对于目前交通管理系统采集海量数据利用效率不足的问题,以青岛胶南市的部分交通流量数据为例,通过R语言对交通流量的可视化探索R在交通流量可视化中的应用;利用R语言的简单编码对交通流量数据实现不同形式的可视化;结合胶南市部分路口的监测线圈数据对其交通流量的状况用R进行可视化;通过R绘制地图、趋势图、比例图、分面图、三维图来分析研究R的可视化效果。结果显示,R语言可以通过简洁的代码设计来实现良好的数据分析效果,在可视化数据挖掘中的优势明显。
In view of the fact that the massive data from the traffic management system haven’t been used effectively, taking some traffic flow data of Jiaonan City in Qingdao City for example, we explored the visualization application of R in traffic spatio-temporal data through traffic visualization of R. We used R code to visualize traffic flow data in different forms. Combining with the monitoring coil data in part of the intersection in Jiaonan City, we used R to visualize the traffic flow. We analyzed the visualization effect of R by map, trend map, scale map, faceted map, 3D map, which drew by R. The result shows that R can achieve data analysis effect greatly by the succinct code, and have advantages obviously in visual data mining.
