The article necessitates the implementation of intellectual transport system to provide efficient responding systems in case of traffic accident. The author gives grounds to the way of reduction of seriousness of traffic accidents due to the whole range of measures including modern science technologies. ITS is intended for increase in safety of transport processes and is used for full informing of special divisions in case of dangerous situation. The directions of development of RITS - technological and methodological are closely interconnected. Methodological direction is algorithms and computer programs to transfer, process and get information about traffic accident. The article analyses experience of use of different elements of ITS with purpose of controlling transport flows and increase of safety on the roads in EU countries. The author drives at conclusion that developed and used systems are not related to each other by common concept of Single European ITS. The author also analyses the studies of home scientists on methodological direction of ITS. The author reasonably argues that methodological direction of ITS use to provide safety of traffic in our country has just started.
