Intelligent speed adaptation: accident savings and cost–benefit analysis

Abstract: The UK External Vehicle Speed Control project has made a prediction of the accident savings with 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. A more complex version of the mandatory system, including a capability to res… Show more

“…Nevertheless, the 16 safety case for ISA has been well documented (e.g., Carsten and Tate, 2005; although see Young et al, 2007, for a view of some safety concerns with ISA), and ISA may have environmental benefits too, by encouraging a smoother traffic flow. Servin et al (2006) used simulation modelling to demonstrate that ISA could reduce fuel use by up to 70% and emissions by up to 93%, although the effects would be restricted to highly congested conditions.…”

“…According to the project implemented by Carsten and Tate (2005) in the United Kingdom, 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. A more complex version of the mandatory system, including a capability to respond to current network and weather conditions, would result in a reduction of 36% in injury accidents and 59% in fatal accidents.…”
