Transport for London (TfL) is developing an intelligent speed adaptation (ISA) system, which it claims could cut road casualties in London by 10% if two-thirds of motorists used it.
The technology enables drivers to select an option where acceleration is stopped automatically at the speed limit specific to any road in London within the M25 area.
The device can be disabled at the touch of a button, at which point it reverts to an advisory status where the current speed limit is simply displayed as a driver aid. There is also a complete override switch with disables the system entirely.
The technology will be tested in the six-month trial after which a report will be submitted to the mayor of London and the technology will be made available to external organisations.
TfL plans to install the system in a taxi and 20 of its own vehicles and Southwark Council has already expressed an interest in fitting ISA to more than 300 of its vehicles.
The trial will monitor driver behaviour, journey times and the effect that driving within the speed limit has on vehicle emissions.
Chris Lines, head of TfL’s road safety unit, said: "We know the technology works, and now we want to know how drivers in all types of vehicles respond to it.”
