城市轨道交通车站是城市轨道交通网络的关键节点。识别和分析城市轨道交通站点周边土地利用特征，对城市轨道交通运营管理具有重要意义。为此，提出了一种基于POI的城市轨道交通站点周边土地利用特征可视化方法。该方法首先利用Voronoi图确定城市轨道交通站点的覆盖范围，并根据每个POI的物理位置将其放入一个覆盖区域。然后，基于天际线的思想，提取城市轨道交通各站点的面向主题的层次兴趣点。最后，城市轨道交通车站周围的土地利用特征可视化提取的层次感兴趣的基础上。我们进行了两个案例研究和质量评估。并以北京市轨道交通实际数据为例进行验证。研究结果表明，该方法能够明确城市轨道交通车站用地的各种情况，为交通模型技术的应用提供支持。
Urban rail transit stations are the key nodes of urban rail transit network. Identifying and analyzing land use characteristics around urban rail transit stations can significantly contribute to urban rail transportation operation and management. Therefore, a visualization method of land use characteristics around urban rail transit stations based on POI is proposed in this paper. In the proposed method, first, the Voronoi diagram is used to determine coverage of urban rail transit stations and each POI is put in a coverage area based on their physical location. Then, topic-oriented hierarchical POIs of each urban rail transit station are extracted based on skyline idea. Finally, the land use characteristics around an urban rail transit station are visualized based on the extracted hierarchical POIs. We carried out two case studies and a quality evaluation. By using realistic data from Beijing rail transit in order to validate the method proposed in this paper. Results show that our method can clarify various situations of land use of urban rail transit stations and may provide support for the application of transportation model technology.
