The main aim of this study was to assess the potential impacts of real-time personal road traffic in-vehicle information systems on injury accidents in Finland. An expert survey was used to measure the safety impacts. The results showed that a weather and road condition warning service and a well-implemented route and service guidance system would improve traffic safety and reduce the number of injury accidents in Finland. Incident warning systems do not have a notable safety impact due to the small number of incidents on Finnish roads, but their primary purpose is to improve traffic flow.
