Research results in Australia indicate that installation of advisory Intelligent Speed Adaptation (ISA) systems in government vehicles would reduce collisions by a fifth. This would eliminate 171 casualty crashes (involving death and injury) according to the study by the University of Adelaide’s Centre for Automotive Safety Research (CASR). The new CASR study analyses the impact of advisory ISA systems that warn the driver about the vehicle speed (not systems that automatically prevent the driver from exceeding the speed limit). Fitment of advisory ISA to state government vehicles is predicted to save A$31.6 million (€22.5 million) in crash costs per year.
“While there is general consensus that Advanced Driver Assistance Systems (ADAS) such as ISA have important safety benefits, statistical proof will only emerge once a significant number of systems are fitted to the car parc,” says Stephen Longden, author of SBD’s recent report Kickstarting the mass market for ADAS ~ a review of the key market drivers.
“The spread of ADAS to mass market and city segment models such as the Ford Focus and Volkswagen Up! will see significant growth in uptake. This will allow governments and the insurance industry to evaluate the impact of ADAS on traffic safety and collision claims,” explains Longden.
CASR found that a system based on a Portable Navigation Device (PND) with added advisory ISA functionality was the most cost effective with a payback period of around one year. This system provides an audible warning if the speed limit is exceeded. The unit is priced A$135 with an additional A$50 fee for an annual download of map data including speed limits.The research is funded by the Australian government’s Transport Accident Commission as part of the Australasian Intelligent Speed Assist Initiative that involves system demonstrations and academic studies.
