摘要
滴滴出行数据中包含了丰富的用户位置信息、出行时空属性、用户行为规律与特征,通过对这些信息的深入分析与挖掘,并结合可视化技术,以图形图像的方式展示,有助于分析用户出行的规律。为了直观展示海口市交通流量动态变化,分析车辆出行的时空规律和交通出行路况,设计一个可视化分析系统。以日历图、径向柱状图等可视化方法为依据,结合可视化工具,从出行数据的不同维度着手分析海口市交通流量情况。该系统能够客观地反映海口市交通变化情况,可以为交通管理规划提供合理的依据。
Didi Chuxing data contains a wealth of user location information,travel spatial-temporal attributes,user behavior rules and characteristics.Through in-depth analysis and mining of these information,it can be displayed in the form of graphics and images combined with visualization technology,which is helpful to analyze the user travel rules.A visual analysis system is designed to show the dynamic changes of Haikou traffic flow and to analyze the temporal and spatial law of vehicle travel and traffic conditions.Based on calendar chart,radial histogram and other visualization methods,combined with visualization tools,the traffic flow of Haikou City is analyzed from different dimensions of travel data.The system can objectively reflect the traffic changes in Haikou City and provide a reasonable basis for traffic management planning.
