Mobile Laser Texture Profiling Method for Cost-Effective Road Safety Assessment

Abstract

Road surface profile quality plays an important role in defining pavement material functionality. Laser profiling systems are valuable tools for traffic safety, particularly in relation to friction effects. The modelling process begins with contactless remote surface scanning of materials. It is based on the interaction between coherent light and the surface, followed by various signal-processing techniques. Mobile scanning systems are based on multisensory platforms moving along the road surface. It is important to evaluate movement-related effects such as vibrations of the moving system, changes in platform velocity, macro-level surface irregularities, and similar structural material issues. Precise laser signal scanning techniques contribute to the development of risk prediction models that support traffic safety in situations where friction-related problems arise. Moreover, these mobile profiling methods are cost-effective. They improve safety, maintenance planning, and lifecycle cost management while reducing both survey time and traffic disruption without requiring road lane closures.
