Intermodal Traffic Reference System (GIP.at) Straßengraph Wien

The street graph is a topological graph of the section network of Vienna’s streets. The network lines usually run on the road axis. A section of the road is part of a road between two intersections. The stationing direction is carried out according to the ascending orientation numbers. Road sections are limited by grid nodes. These net nodes are usually located at the cross-mechanical point. This dataset extends the public transport areas (municipal roads, main roads A and B).本街道图是维也纳街道断面网络的拓扑图（topological graph）。该网络线条通常沿道路轴线布设。道路路段指两条交叉口之间的道路区段，其布设方向依照递增方位编号确定。道路路段由网格节点界定，此类网络节点通常设于道路交叉口处。本数据集拓展了公共交通覆盖范围（含市政道路、A类与B类主干道）。
