Data subset for road condition modelling - reference data

The subset contains selected standard road condition data from the LiRA project.
The subset contains standard road condition measurements from vehicles operated by the Danish Road Directorate (DRD). The surveying included: (i) P79 Profilometer – a van equipped with a beam hosting 25 point lasers that measure longitudinal and transverse profiles; (ii) ARAN9000 – a multi-functional road scanning vehicle that quantifies road defects and distresses using cameras and a Laser Cracking Measurement System (LCMS); and (iii) VIAFRIK – a skid resistance device complying with CEN/TS 15901-5 standard.
The reference data (.csv) is stored in a flat format; each column represents a road condition parameter, GPS information or timestamp, while each row represents a new record in time or space.

本子集汇集了来自 LiRA 项目精选的标准道路状况数据。该子集包含了丹麦道路管理局（DRD）运营车辆收集的标准道路状况测量数据。测量手段包括：（i）P79型轮廓仪——一种配备25点激光束的货车，用于测量纵向和横向轮廓；（ii）ARAN9000——一种多功能的道路扫描车辆，利用摄像头和激光裂缝测量系统（LCMS）对道路缺陷和损伤进行量化；（iii）VIAFRIK——一种符合CEN/TS 15901-5标准的抗滑阻力装置。参考数据（.csv格式）以扁平结构存储；每一列代表一个道路状况参数、GPS信息或时间戳，而每一行则代表一个在时间或空间上新的记录。
