The Highways Agency conducts routine automated surveys of trunk road pavement surface (TRACS) and structural (TSD) condition. From these surveys, the Agency is able to establish the condition of the network, prioritise reconstruction and repair work and value its road assets. However, the infrastructure of the trunk road network includes assets other than pavements - the network contains bridges, signs, gantries, lighting, embankments, drainage systems and many types of roadside furniture – none of which are assessed using current automated routine surveys. This report details an investigation into the potential for the use of LIDAR as a routine tool for the measurement and assessment of road infrastructure assets, and to determine how this information could be used to assist the effective management of the network.
