State of development of intelligent transport systems services on national roads in Poland

In recent years we can see intensifying implementation of Intelligent Transport System (ITS) measures in Polish cities and on national roads. The architecture of the National Traffic Management System (KSZR) will enable the implementation of a uniform, integrated and intelligent ICT system to launch ITS systems that are the most important for drivers and the General Directorate for National Roads and Motorways (GDDKiA). This paper presents the current state of the implementation of the ITS services on national roads in functional, physical and logical terms and the premises for the KSZR’s development. The description of the state of the development of ITS services on national roads was compiled within the framework of the RID 4D “The impact of the usage of Intelligent Transport Systems services on the level of road safety” research project, funded by the National Centre for Research and Development and the General Directorate for National Roads and Motorways.
