Data from OpenStreetMap (OSM) is used as a data base. The accessibility zones (isochrons) are calculated using the OpenRouteService. For this purpose, the road network of OpenStreetMap is used, missing or incorrect road geometries and attributes such as speed limits cannot be excluded.Please note that the derived journey times may differ significantly from actual driving times, e.g. due to current traffic conditions or traffic restrictions such as traffic jams or construction sites. Therefore, no guarantee can be assumed for the correctness of the calculation results and map presentations.

API of the OpenRouteService: https://openrouteservice.org/dev/#/api-docs本数据集采用开放街道地图（OpenStreetMap, OSM）的数据作为数据库。 本数据集的可达性区域（等时圈，isochrons）通过开放路线服务（OpenRouteService）计算得到。在此过程中，将使用开放街道地图的道路网络，但无法排除存在缺失或错误的道路几何形状与属性（如限速信息）的情况。 请注意，推导得出的行程时长可能与实际驾驶时长存在显著差异，例如受实时交通状况、拥堵或施工等交通管制因素影响。因此，本数据集不对计算结果与地图展示的准确性提供任何保证。 本数据集采用开放街道地图的数据作为数据库。 本数据集的可达性区域（等时圈）通过开放路线服务计算得到。在此过程中，将使用开放街道地图的道路网络，但无法排除存在缺失或错误的道路几何形状与属性（如限速信息）的情况。 请注意，推导得出的行程时长可能与实际驾驶时长存在显著差异，例如受实时交通状况、拥堵或施工等交通管制因素影响。因此，本数据集不对计算结果与地图展示的准确性提供任何保证。 开放路线服务的API接口： https://openrouteservice.org/dev/#/api-docs
