Most people use maps for navigation. Geographic maps visually represent physical distance between locations. These maps sometimes provide a false impression of travel times. Two cities geographically close to each other might be “far apart” in terms of travel time because of slower connections, whereas two cities geographically distant might be “nearby” in terms of travel time because of faster connections. Under such circumstances, visualizing a transport network using time as a distance measure can make the transport network more understandable. This study integrates several (carto)graphic representations—a time line, a distance line, a time prism, a time cartogram, and a geographic map—in an interactive linked-views environment to model reachability in transport networks. A prototype is implemented in a web environment using D3.js. The implementation can be applied to any transport network. In this research, the approach is illustrated with railroad network data for the Dutch province of Overijssel. The solution provides an alternative and insightful perspective for analyzing the data. In addition to complementing a wide variety of methods to visualizing travel times, the approach could be applied in areas such as spatial analysis and transport planning.

在运输网络中建模可达性:在交互式链接视图中使用替代的视觉表示获得有价值的见解

大多数人使用地图进行导航。地理地图直观地表示了位置之间的物理距离。这些地图有时会给人错误的旅行时间印象。由于连接速度较慢,所以两个城市的地理位置在行进时间上可能“相距较远”,而由于连接速度较快,在地理位置上相距较远的两个城市在行进时间方面可能“就近”。在这种情况下,使用时间作为距离度量来可视化运输网络可以使运输网络更易理解。这项研究在交互式链接视图环境中集成了多个(地图)图形表示(时间线,距离线,时间棱镜,时间制图和地理地图),以建模运输网络中的可达性。原型是使用D3.js在Web环境中实现的。该实现可以应用于任何传输网络。在这项研究中,该方法通过荷兰Overijssel省的铁路网络数据进行了说明。该解决方案为分析数据提供了另一种有见地的视角。除了补充多种方法来可视化旅行时间外,该方法还可以应用于空间分析和运输规划等领域。
