TRAVELLER CENTERS Personal Information Access Remote Traveler Support subsystems (light blue boxes) contained in the US Physical architecture are shown in Figure 2. These subsystems can broadly be divided into four classes as illustrated by the larger coloured boxes (denoted functional blocks in the standard) named “Traveller”, “Centers”, “Vehicles” and “Roadside”. The specific choice of twentyone service subsystems represents a lower level of partitioning of functions that is intended to capture all anticipated subsystem boundaries for the present, and 20 years into the future. Figure 2 is often referred to as the “sausage diagram”, referring to the shape used for the communications services connecting the functional blocks. The thin lines represent the main information paths and type of information exchanged. 4 About the Merger of Automotive, Communication and Computer Industries A modern car has many hundred motors, sensors, actuators and many computers. The top models usually have several interconnected networks between all the computers and microcontrollers. In-vehicle standards (responsibility of the ISO/TC22 Road Vehicles committee) try to harmonize the utilisations of control means and practices within the vehicle. With so much electronics, no wonder efforts are under way to harness the possibilities in a comprehensive platform for safety, driving efficiency, maintenance and entertainment.

Fleet and Freight Management One interesting issue that ought to be mentioned (writing for a telecom journal) is a surprising decision made last year by the US standardisation group and then by the corresponding ISO TC204, working group, when they voted in favour of using the IEEE 802.11a R/A (roadside applications) as the preferred technology to provide the national interoperability for DSRC Public Safety-based applications. Simultaneous with this DaimlerChrysler Research and Technology North America demonstrated a Mercedes Benz with 802.11a capability and a concept of “Info- Fueling” [6]. The annual meeting of ITS America this year featured a session “Next-Generation ITS Radio communication Services: Impact on Public Safety”. The session discussed the clear delineation that is now emerging between next-generation Broadband ITS Radio communication Services that are intended to provide a long and medium-range communications capability and Dedicated Short-Range Communications (DSRC) limited to short-range devices. The panel discussed the significant activities, both RF and infrared, being treated by ISO/TC204 regarding Continuous Air-interfaces Long and Commercial Vehicle Adminstration Wide Area Wireline (fixed point to point) Communications Roadway Toll Collection Parking Management Maintenace & Constr.
