Silent and safe roadtraffic-project: An optimization of the tyre-road interaction on noise and wet grip

The tyre-road interaction is responsible for many tyre and road 'characteristics' like rolling resistance, noise, hydroplaning and wet grip. In the EC legislation R1222 the 'tyre characteristics' are measured using 'standard roads'. Whearas 'road characteristics' like noise in the IS011819-2 and skid resistance are often measured using 'standard tyres'. As the standards are often old technology, real innovative steps are hard to achieve. Therefore the project 'Stil Veilig Wegverkeer' is started, translated as 'Silent and Safe Roadtraffic', where the tyre-road interaction is studied in more detail regarding noise and wet grip. With new developed simulation and test methodogies the tyre-road combination is optimized. An overview of the project and the first results will be given
