Transport for London (TfL) is to test a system that can automatically reduce a vehicle's speed, as part of a strategy to reduce road deaths.
TfL is initially aiming the Intelligent Speed Adaptation (ISA) scheme at public vehicles like buses and taxis. Any roll-out to private vehicles would require owners to fix sensors to their vehicles.
At first, the ISA system would alert drivers, via satellite navigation systems for instance, that they are entering reduced speed zones. If the driver did not slow down, the system could force the vehicle to slow to the correct speed.
TfL believes though that closely monitoring and controlling public vehicles could have a knock-on effect of slowing whole traffic streams, where appropriate.
TfL is expected to start trials into the technology in early 2006, involving around ten vehicles.
