Young, Michael A. Regan, General, 2002-2003 Eve Mitsopoulos & Narelle Haworth Sponsoring Organisation(s): Motor Accidents Authority (MAA) of New South Wales Abstract: This report describes the outcomes of a study funded by the Motor Accidents Authority (MAA) of New South Wales (NSW) to assess the acceptability, to a sample of young novice drivers from metropolitan and rural NSW, of seven in-vehicle ITS technologies: Intelligent Speed Adaptation; Forward Collision Warning; Following Distance Warning; Lane Departure Warning; Fatigue Warning; Alcohol Interlock and Sniffer systems and the Drink Driving Performance Test; Seat Belt Reminder; and Electronic Licence. This was achieved by conducting eight focus groups, four in Sydney (metropolitan) and four in Wagga Wagga (rural), involving 58 drivers aged 17 to 25 years who, from examination of NSW crash data, were likely to derive the greatest safety benefits from the selected technologies. For each technology discussed, the acceptable attributes of the system, as well as the barriers to their acceptance that were raised by participants, were identified. Differences in the acceptability of the systems that emerged between the metropolitan and rural participants were also identified. Overall, the Alcohol Interlock and Seat Belt Reminder systems were deemed the most acceptable to young drivers, while the Fatigue Warning (for rural participants only), Intelligent Speed Adaptation and Lane Departure Warning had the lowest levels of perceived acceptability. The metropolitan and rural participants’ attitudes towards the systems were generally very similar, however a number of differences in the acceptability of several technologies were observed. Suggestions for enhancing the acceptability of ITS technologies to young novice drivers are offered. The report concludes with recommendations for further research.
