Cities worldwide exhibit a variety of street network patterns and configurations that shape human mobility, equity, health, and livelihoods. This study models and analyzes the street networks of every urban area in the world, using boundaries derived from the Global Human Settlement Layer. Street network data are acquired and modeled from OpenStreetMap with the open-source OSMnx software. In total, this study models over 160 million OpenStreetMap street network nodes and over 320 million edges across 8,914 urban areas in 178 countries, and attaches elevation and grade data. This article presents the study’s reproducible computational workflow, introduces two new open data repositories of ready-to-use global street network models and calculated indicators, and discusses summary findings on street network form worldwide. It makes four contributions. First, it reports the methodological advances of this open-source workflow. Second, it produces an open data repository containing street network models for each urban area. Third, it analyzes these models to produce an open data repository containing street network form indicators for each urban area. No such global urban street network indicator data set has previously existed. Fourth, it presents a summary analysis of urban street network form, reporting the first such worldwide results in the literature.

世界上每个城市地区的街道网络模型和指标

世界各地的城市展示了各种街道网络模式和配置，这些模式和配置塑造了人类的流动性、公平性、健康和生计。本研究使用源自全球人类住区层的边界对世界上每个城市地区的街道网络进行建模和分析。街道网络数据是使用开源 OSMnx 软件从 OpenStreetMap 获取和建模的。总的来说，这项研究对 178 个国家的 8,914 个城市地区的超过 1.6 亿个 OpenStreetMap 街道网络节点和超过 3.2 亿条边进行了建模，并附上了高程和坡度数据。本文介绍了该研究的可重复计算工作流程，介绍了两个新的开放数据存储库，其中包含现成的全球街道网络模型和计算指标，并讨论了全球街道网络形式的总结发现。它做出了四项贡献。首先，它报告了这个开源工作流的方法学进展。其次，它生成了一个开放的数据存储库，其中包含每个城市区域的街道网络模型。第三，它分析这些模型以生成一个开放的数据存储库，其中包含每个城市区域的街道网络形态指标。以前没有这样的全球城市街道网络指标数据集。第四，对城市街道网络形式进行了总结分析，在文献中报告了世界范围内的第一个此类结果。以前没有这样的全球城市街道网络指标数据集。第四，对城市街道网络形式进行了总结分析，在文献中报告了世界范围内的第一个此类结果。以前没有这样的全球城市街道网络指标数据集。第四，对城市街道网络形式进行了总结分析，在文献中报告了世界范围内的第一个此类结果。
