WILLWARN final report
Safe speed and safe distance are key factors for safe driving. This is the reason why PReVENT defined a function field for this topic. Within this function field WILLWARN (Wireless Local Danger Warning) contributes to foresighted driving using vehicle communication. The scope is early warning because of hazards
some seconds before the driver meets the dangerous spot. Accident statistics show that many accidents are caused by driving too fast and too close and because of this by drivers who react too late before dangerous situations. The German accident statistics from 2004 shows, that 26.8% of all accidents with injured persons
were caused by not adjusted speed and following distance. Many accidents occur under bad weather conditions. Again in Germany in 2004 19000 accidents were caused by bad weather. Road safety can be improved by early warning based on vehicle communication. WILLWARN started with the ambition to close the gap between former approaches like the simple “Extended Warning Flashlight” from the DEUFRAKO project IVHW – Inter Vehicle Hazard Warning and the ad-hoc network based systems from the German project FleetNET and the EU project CarTalk2000 which presumed high rates of vehicles equipped with communication. These projects are marking both ends of the scale of equipment rates but a system was missing that had the chance to enter the market with an attractive high functionality and that
prepares the way to high penetration rates. Thus WILLWARN aims at a full application (not only communication technology and protocols) and takes care of low penetration rates in the beginning.
