The ROSES (ROad Safety Enhancement System) project is part of the European DRIVE ii initiative. Its aim is to develop and implement a fully integrated monitoring system for traffic, weather and road condition, in order to support: (1) drivers, (2) traffic management and (3) winter maintenance decisions under adverse weather conditions, such as poor visibility, slippery conditions and strong cross-winds. This is achieved by integration of road-side systems and vehicle based monitoring and information systems. The ROSES system will be implemented at two different test sites and in a test vehicle. One of the problems to overcome is the lack of a common and practical understanding of hazardous conditions. Therefore, the influence of bad weather on traffic safety is studied through both field observations and model simulation of microscopic traffic behaviour. Quantification of safety for practical use is attained by combining safety margin assessment from: (i) in-vehicle and (ii) the road-side (traffic control) point of view. With ROSES, an integrated safety assessment procedure is proposed.
