The concept of advanced traveller information systems (ATIS) is a component of intelligent transport systems (ITS) and is believed to be a valuable resource to travellers. However, the benefits of ATIS are achieved only when travellers respond to the information conveyed by ATIS in a positive manner. In this context, this paper describes the user needs and preferences derived from a survey of Sydney commuters. The radio traffic information system is a well-established traffic advisory system available to the motorist, and therefore motorist attitudes and preferences to real time information are investigated using radio based information delivery as a case study. The main findings are as follows. It is seen that drivers thought of radio traffic information systems as generally accurate, and that information on dynamic conditions such as traffic conditions and road accidents is preferred to information on relatively static knowledge such as alternative routes. On the aspect of technology preference, radio has overwhelming support compared to computers and telephones. (A)
