Transport for London Trailing Vehicle Speed “Governor” this Summer
The GPS-based box has two modes: one will in fact limit speed such that it does not exceed the limit set for that roadway while the second gives a green smiley when the vehicle is within the acceptable range and a red sad face when it is not. The trial set for this summer includes installing the devices on cars and a bus and will operate within the M25 ring. The device is expected to improve safety, cut congestion, save fuel and help the environment. There are no plans to make the device mandatory at this time; the hope is that potential users will see the benefits. Some suggest if even a fraction of drivers use the device, all traffic will slow to their speeds, and enhancing the effect. The technology is called Intelligent Speed Adaptation (ISA).
