Actia UK has been working to meet the requirements of Transport for London (TfL) for the automatic limitation of vehicle speed according to location.
A telematic ECU is fitted on the bus containing a map of London’s road network. The system restricts the vehicle to the speed limit depending on the road.
GPS and algorithms communicate directly with the engine to restrict the throttle.
The system has been rolled out on three manufacturers: Wrights, Optare and ADL, as well as to different operators in London.
