New possibilities for evaluating the measured profile of road surfaces (macrotexture) will be analyzed, rather than the previously used MPD parameter (mean profile depth), which has its limitations. The aim is to ensure that the new parameter, in combination with other inputs, enables the prediction of road surface noise (CPX method) and road surface skid resistance (longitudinal friction coefficient Fp). Macrotexture is measured on a much larger scale than noise and skid resistance, yet MPD values are not widely used in road management systems. This approach (analytical tool and new parameter describing macrotexture) would enable greater use of regularly repeated macrotexture measurements performed on different types of road surfaces (classic, BPÚ-safety anti-skid treatments, low-noise).

This project, Determination and optimization of vegetation strips with natural tree species composition for traffic noise reduction, is co-financed with state support from the Technology Agency of the Czech Republic and the Ministry of Transport of the Czech Republic under the TRANSPORT 2030 Program. This project is financed under the National Recovery Plan from the European Recovery and Resilience Facility.
