The value of the transport performance is constantly increasing, which contributes to the increased traffic of transport vehicles. In Poland, the main kind of transport is the road transport, as indicated by the data published by the Central Statistical Office. The main factors determining the safety of the road transport system are the number of accidents, injuries and victims of road accidents. In order to minimize the risk of a road accident occurrence or its consequences, newer infrastructure solutions in the field of road traffic and systems installed in vehicles are developed. Despite a significant increase in road traffic, the rates of accidents, injuries and victims of road accidents are decreasing, which proves that modern solutions are working properly.
