In-vehicle intelligent speed advisory systems

Abstract

We review research findings on intelligent speed adaptation (ISA) and evaluate a self-contained, onboard speed advisory system that alerts drivers when the prevailing speed limit is exceeded (passive ISA). Recent developments in technology, including improvements to GPS and other navigation aids, mean that ISA has become a commercial reality rather than an experimental novelty. Passive and active ISA systems are now on sale in Australia. Extensive trials of ISA throughout the world have demonstrated the potential for significant accident savings as well as other community benefits. There is a compelling case for governments to actively support ISA implementation.
