| 摘 要： | 可视化分析技术在分析交通数据、发现交通问题及辅助决策扮演着越来越重要的角色，成为一项重要的智能交通技术。为了更加直观地展示城市公交线网空间分布的疏密情况，本文基于北京市公交线路矢量数据，采用直接可视化和聚集可视化两种方法对公交线网的空间分布进行了分析。通过对原数据处理计算得到了基于北京市主干道的公交线路分布数据并进行了直接可视化；同时利用HTML5的Canvas绘制热力图的方法对原数据进行了聚集可视化，根据可视化结果对北京市公交线路空间分布情况进行了分析。该方法对城市公交线网规划和优化有实用价值和意义。

| Abstract: | Visual analysis technology is playing an increasingly important role in the analysis of traffic data and the discovery of traffic problems and decision making.In order to intuitively show the city transit network spatial distribution density,the vector data of Beijing city bus lines is analyzed based on the direct visualization and visualization method of two kinds of aggregation distribution of transit network spatial analysis.The original data processing is calculated for direct visualization of bus lines in Beijing city main roads based on data distribution method.The canvas drawing thermodynamic diagram is used on the original data visualization.The visualization results according to the analysis of the situation of spatial distribution of bus lines in Beijing city show that this method has practical value and significance of city public transportation network planning and optimization. |
