CHOICE OF WIRELESS TELECOMMUNICATIONS SYSTEMS FOR EARLY ITS IMPLEMENTATIONS
Robert Belec, Ivana Bošnjak, Tomislav Kljak · 1999
Choice of wireless telecommunications solutions for early Intelligent Transportation Systems (ITS) implementations must be systematically considered in the context of national and European ITS architectural frameworks. In this paper, a more technically/technologically oriented description and evaluation is provided for expected first ITS services (urban traffic management and traveler information services). For expected first ITS applications and respective information flows between traffic/transportation entities, several potential wireless telecommunications systems are evaluated. It is concluded that Radio Data System/Traffic Message Channel, SMS over GSM, and new GPRS systems based on datagram transmission have significant advantages over one-way broadcasting and circuit-switched dial-up connections.
