Significant increase in traffic demand at the end of the 20th century and the increasing anthropogenic environmental pollution have resulted in the need to introduce the telematics-supported intelligent transport systems in all the traffic branches. The work presents the development and the basic characteristics of transport systems managed by information and communication technologies. It also gives an overview and explanation of the operation of some of the numerous telematic systems in traffic, and a detailed presentation of the telematics-controlled public transport of the city of Helsinki. It also presents the possible development and advantages of implementing telematics in the transport along the river Danube through Austria.
