Transport for London begins testing GPS-linked speed limiters

 

Transport for London (TfL) will begin a six-month trial of Intelligent Speed Adaptation (ISA) technology which aims to reduce road casualties and help drivers avoid speeding penalties.

The intelligent technology, which works in conjunction with a GPS, 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 unit can be disabled at the touch of a button, at which point it reverts to an advisory status where the current, legal speed limit is simply displayed as a driver aid. There is also a complete override switch with disables the system entirely.
