ISA uses global satellite positioning (GPS), a digital map to establish a car’s location and sign recognition cameras to identify what the speed limit is at any point on the road.
This information can be used to:
Once controlling ISA has identified the speed limit, it does not allow the driver to accelerate beyond it. The promise that speeding fines, penalty points and subsequent loss of licence will become things of the past is an attractive proposition. In the UK alone, millions of motorists are fined and given penalty points for speeding every year. A team from the University of Leeds and the Motor Industry Research Association (MIRA) has found that the system could achieve significant reductions in road crash deaths and injuries. This was confirmed in a 2017 report by TRL for the EU that recommended ISA, and a range of other vehicle technologies, as a positive benefit for road safety. This led to the introduction of the GSR2 (General Safety Regualtion2) which will lead to the installation of advisory ISA in all new cars in the EU from 2022.
