Influence of Intelligent Transport Systems services on motorways road safety

The positive effects of Intelligent Transport Systems (ITS) services on road safety was confirmed by long-term studies conducted, inter alia, in the USA, Japan and Europe. Benefits resulting from the application of ITS services can be presented through performance indicators. The paper presents analysis results of the influence of existing ITS services on road safety on motorways in Poland and indicators describing that impact. For the purpose of the analysis data of accidents (years 2013-2015) are used to describe safety level for motorways with different number and scope of ITS services. Additionally, the authors analyzed - based on the diagnosis of the traffic status - the possibility of the impact of existing and planned ITS services on improving the road safety in the area of the National Road Traffic Management System (Krajowy System Zarządzania Ruchem, - KSZR). Current level of ITS services on Polish motorways within the architecture of KSZR System and state of its development will be presented as well.
