The invention belongs to the technical field of visualization and visual analysis, in particular to a visual analysis method combining real-time traffic road condition text data with traffic volume. The method comprises the following steps: firstly, writing a web crawler program by using Python to obtain traffic-related unstructured text information in a social media website, and converting the unstructured text information data into structured information data by using Chinese word segmentation, part-of-speech tagging and an entity naming identification method; and then visually displaying the structured information data in the modes of a map basic view, a traffic event view, a flow thermal view, a theme river view and a road flow data view. According to the invention, traffic informationpublished in the current social media can be quickly acquired, information behind an event can be further mined through a visual technical means, more visual experience is provided for users, and meanwhile, a relatively strong data analysis capability is provided for relevant management departments of cities, so that the decision-making efficiency of traffic management of the users is improved.
本发明属于可视化与可视分析技术领域,尤其涉及一种实时交通路况文本数据结合交通量的可视分析方法,包括如下步骤:首先利用Python编写网络爬虫程序获取社交媒体网站中交通相关的非结构化的文本信息,利用中文分词、词性标注以及实体命名识别方法将非结构化的文本信息数据转为结构化的信息数据;然后对结构化的信息数据以地图基础视图、交通事件视图、流量热力视图、主题河流图视图和道路流量数据视图的方式进行可视化展示。本发明可对当前社交媒体中发布的交通类信息进行快速获取,还可通过可视化的技术手段进一步挖掘事件背后的信息,为用户提供更直观的体验,同时为城市的相关管理部门提供较强的数据分析能力,以提高他们交通管理的决策效率。
