Road maintenance works

The roads are divided into separate maintenance contracts, which are managed by contractors who are tendered periodically. The map material presents, among other things, the different areas of care, the duration of the works and the contractor who manages the project. Three separate map levels have been published for road maintenance projects, the difference being the date of their situation. Changes in road maintenance works take place on the first day of October, which means that the actual limits may differ from the situation at the end of September at the beginning of October. The status dates for map levels are 1 October 2022, which describes the past situation, 1 October 2023, which describes the current situation and 1 October 2024, which describes the future situation. The material is updated once a year in the autumn.道路工程均划分至独立的养护合同项下，由定期招标遴选的承包商负责管理。本地图数据集涵盖的内容包括各类养护作业分区、工程工期以及负责项目管理的承包商等信息。本次道路养护项目共发布三个独立的地图层级，其差异在于各自对应的场景日期。道路养护作业的变更均于每年10月1日生效，这意味着10月初的实际作业范围可能与9月底的既有状况存在差异。各地图层级对应的状态日期分别为：2022年10月1日（对应历史场景）、2023年10月1日（对应当前场景）以及2024年10月1日（对应未来场景）。本数据集每年秋季更新一次。
