英国交通研究实验室：2024年众包数据在道路状况评估中的应用研究报告（英文版）

On the Strategic Road Network (SRN) monitoring of pavement asset condition is currently achieved using dedicated surveys that measure the functional (e.g. user experience such as roughness, and visual appearance), safety (e.g. skid resistance) and structural (e.g. bearing capacity) condition. This data is provided by annual network level surveys to support long term planning, and more frequent data collection to detect defects that are rapidly developing (e.g. potholes). In recent years a new so
