In the final project is discussed about different traffic-travel information services for motorways users before and during the trip. The traffic is increasing and in the future building of new roads and traffic infrastructure will not be possible, because of economic and space capacities. Because of this is becoming more and more important the development of modern systems for monitoring and leading traffic. In this field an advanced traffic information service has a key meaning. For this reason there is a Slovenian and foreign traffic information services overview. There are analyzed technologies like are GSM-SMS, WAP, UMTS, internet, GPS, DAB, TMC-RDS etc. RDS-TMC system is actually one of the best for delivering real-time information. The Traffic Message Channel (TMC) is a specific application of the FM Radio Data System (RDS) used for broadcasting real-time traffic and weather information. Data messages are received silently and decoded by a TMC-equipped car radio or navigation system, and delivered to the driver in a variety of ways. RDS-TMC system uses ALERT-C protocol for data exchange. There is also DATEX protocol, which was developed for information exchange between traffic management centres and constitutes the reference for applications that have been developed in the last 10 years. DATEX II is an upgrade of DATEX and now also pushes the door wide open for actors of the traffic and travel information sector. Before mentioned technologies represents data interfaces in the ITS physic architecture of a traffic information service.
