The impact of Intelligent Transportation Systems on road safety in Poland

An Intelligent Transportation System is a modern solution which aims to improve the functioning of transport by, among other things: reducing congestion, shortening travel time, or improving road safety. This solution is used in many cities around the world, bringing economic effects and improving the comfort of life of the inhabitants. In Poland, as a result of the European Union’s promotion of the de- velopment of intelligent transport systems through their co-financing, many cities have introduced such solutions. In the article, against the background of theoretical considerations, the impact of intelligent transport systems on road safety in the years 2014–2018 was analysed on the example of selected cities.
