A new report by the Commission for Integrated Transport, has concluded that speed limiting technology could reduce the number of deaths and injuries from car accidents by 29%, as well as having significant environmental benefits. However, the report authors have stopped short of calling for intelligent speed adaptation (ISA) technology to become mandatory.

In broad terms, intelligent speed adaptation would mean your car would be electronically restricted from exceeding any speed limits, through a combination of GPS and road-side markers. The technology to introduce such systems (although in its infancy) is now available, however, cost factors as well as a lack of political will mean there is no calls for its immediate introduction.

One significant factor to emerge from the new study was that as well as reduced accident numbers and severity, ISA could also mean a dramatic reduction in CO2 emissions. The reports authors also point out, that despite the massive cost of implementation, mandatory ISA could actually pay for itself within 15 years.
