ENERGY, ENVIRONMENT & RESOURCES ROSANNE MOVES TO IMPLEMENT MANY PRECEDING PROJECTS SUCH AS TYROSAFE ... ROSANNE (ROlling resistance, Skid resistance, ANd Noise Emission measurement standards for road surfaces) is a 36-month FP7 project which aims at developing/harmonising measurement methods for skid resistance, noise emission and rolling resistance of road pavements as a preparation for standardisation. To achieve this, the project will follow the recommendations of key predecessor projects like TYROSAFE (tyrosafe.fehrl.org), HERMES (www. hermesroadmeasurement.eu), SILVIA (www.trl.co.uk/Silvia), SILENCE (www. silence-ip.org) and MIRIAM (Miriamco2.net), as well as consider ongoing work in CEN and ISO. The project, started on 1st November 2013, will develop/improve standards in the field of working group CEN/TC 227/WG 5 and in some cases ISO groups with which CEN cooperates. More specific objectives are: 1. Skid resistance: The harmonisation of skid resistance measurement following the TYROSAFE Roadmap, by deriving conversion factors for friction indices based on similar groups of devices. 2. Noise emission: Merging the existing measurement methods into a harmonised tyre-road noise emission characterisation method. An evaluation of its viability for acceptance testing, monitoring and compatibility with environmental noise calculation methods will also be carried out. 3. Rolling resistance: Building on the results obtained in MIRIAM and standardising trailer measurements of rolling resistance coefficients of road surfaces. 4. Texture: Exploring the potential for recent developments in the measurement of surface texture to deliver parameters that better reflect the physical process of tyre/road interaction. That may improve our understanding of how the texture influences skid resistance, noise emission and rolling resistance. The project aims to produce improved standards for common European measurement methods for skid resistance, noise emission and rolling resistance, which determine the road infrastructure influence on important vehicle performance characteristics. This European approach will arise from the roadmap for implementation and any recommended follow up research. The project will make key road surface parameters accessible to harmonised assessment and management with main potential users being Road Authorities and industry. The results will enable the creation of products and services that bring about considerable cost reductions for Road Authorities and industries with European-wide application due to the possibility to rely on common assessment methods. This would create, for example, a common market for pavements with low noise emission and low rolling resistance.

TYROSAFE recommended more research to increase understanding of the combined influence of the texture of roads and of tyres, which has now led to ROSANNE. TYROSAFE’s main recommendations were the development of European policies and standards to improve the quality of road surfaces and measurement tools for the consistent assessment of road surfaces and tyres. TYROSAFE also provided a roadmap for greater harmonisation in the assessment of road surface properties. Implementation of the TYROSAFE recommendations through ROSANNE would contribute to a greener, quieter and safer road transport system. PARTNERS
