本文提出了一种新的开源工具箱，用于街道网络比较的基础上，Sextante的开源地理信息系统量子GIS（QGIS）的框架。本着开放科学的精神，该工具箱使世界各地的研究人员能够通过计算街道网络比较研究中常用的关键性能指标来评估OpenStreetMap（OSM）等街道网络的质量。此外，我们提出了两个新的性能指标，转向限制和单行道的比较，专门针对测试街道网络的路由质量。我们展示了使用这个工具箱比较OSM和奥地利官方参考图图集成平台（GIP）在更大的维也纳地区。
This article presents a novel open source toolbox for street network comparison based on the Sextante geoprocessing framework for the open source Geographic Information System Quantum GIS (QGIS). In the spirit of open science, the toolbox enables researchers worldwide to assess the quality of street networks such as OpenStreetMap (OSM) by calculating key performance indicators commonly used in street network comparison studies. Additionally, we suggest two new performance indicators for turn restriction and one-way street comparisons specifically aimed at testing street network quality for routing. We demonstrate the use of this toolbox by comparing OSM and the official Austrian reference graph Graph Integration Platform (GIP) in the greater Vienna region.
