Integrated Tyre and Road Interaction (ITARI)


Future trends indicate that passenger road traffic will increase by 20% from 1998 to 2010. Goods transport by road is predicted to increase by almost 40% during this period. To assure that road transport can be considered as sustainable, it is necessary to reduce the negative consequences of road traffic to an acceptable level. Road traffic with its conventional heat-engine vehicles is one of the main sources of urban pollution from greenhouse gases. It also contributes to the European Union's excessive energy consumption. With increasing efficiency of engines, secondary effects such as rolling resistance, now play a dominant role when aiming for further reduction of fuel consumption. Road traffic noise is a major environmental problem. At the CALM workshop a reduction of 19 dB were suggested as short-term target for the year 2010. A major component of road traffic noise is now tyre/road noise. Therefore to achieve the proposed reduction targets it is necessary to reduce tyre/road noise, which is still in the domain of research rather than existing knowledge. Safety is the crucial demand on road surfaces, so design of new low noise textures or textures with low rolling resistance must not risk the grip potential (especially under wet conditions). Currently more than 40,000 persons are killed on EU roads every year, but the strategic objective is to cut this number by 50% within the next eight years and 75% by 2025. The objective of ITARI is to provide the necessary tools to investigate new road surfaces with lower noise emission and lower fuel consumption and at the same time meeting safety requirements. In addition to this ITARI will demonstrate the implementation of virtually prototyped road surfaces in the production process of road surfaces. ITARI will supply knowledge, methodology and insight to enable the research community to develop sustainable road transport for the future'.
