This term is part of the following categories: Safety, Technology, Sensors and Vehicle system.

 

Version: 3.0, Release date: October 2020

Definition: Vehicle system that supports drivers in complying with legally enforced speed limits.

NOTE: Systems can use satellite-based positioning and track the position against a database of speed limits and/or cameras to detect speed limits shown on road signs (including electronic signs amd signals); speed limits may also be broadcast from infrastructure to vehicles to communicate relevant speed limits to the ISA system. Some systems provide a human driver with warnings of excessive speed while others actively moderate vehicle speed to comply with limits.
