道路风险等级及道路属性数据集

道路风险等级及道路属性数据集系道路风险评估车载设备采集，经后期人工编码及预处理的道路风险等级与道路设施属性数据。采集方案系道路风险评估项目组按照《公路安全生命防护工程实施技术指南》中所规定的路网风险评估数据采集标准流程实施。采集地点涵盖我国福建、北京、河南、湖南、贵州等多个省市自治区。采集时间涵盖2016-2018年。数据格式为MySQL 数据库，数据规模涵盖7947.4公里道路，每100米一条，共79474条数据记录，及426760个道路相片，数据存储空间规模计为106GB。The Road Risk Level and Road Attribute Dataset comprises road risk level and road facility attribute data, collected via vehicle-mounted devices for road risk assessment and subsequently subjected to post-collection manual coding and preprocessing. The data collection protocol was developed and implemented by the Road Risk Assessment Project Team in accordance with the standard workflow for road network risk assessment data collection stipulated in the *Technical Guideline on the Implementation of Highway Safety and Life Protection Projects*. Data collection was conducted across multiple provinces, municipalities directly under the Central Government, and autonomous regions in China, including Fujian, Beijing, Henan, Hunan, and Guizhou, with the collection period spanning from 2016 to 2018. The dataset is stored in a MySQL database, covering a total of 7947.4 kilometers of roads, with one data record generated every 100 meters, resulting in 79,474 data records in total. Additionally, the dataset includes 426,760 road photos, with an overall storage size of 106 GB.
