Intelligent Speed Adaptation, and estimated the costs and benefits of national implementation. The best prediction of accident reduction was that the fitting on all vehicles of a simple mandatory system, with which it would be impossible for vehicles to exceed the speed limit, would save 20% of injury accidents and 37% of fatal accidents.

Intelligent Speed Adaptation (ISA) refers to in-vehicle technology systems which assist drivers to keep to or below the speed limit. In 2009-2010 the NSW Centre for Road Safety conducted the NSW ISA Trial which was the largest road safety technology trial ever conducted in Australia. The aim of the study was to find, list and quantify all of the benefits that Intelligent Speed Adaptation (ISA) might hold for South Africa. In addition, an attempt was made to provide an initial estimate of the cost savings that ISA could offer the country if it is implemented in full.
