Abstract
This invention relates to a method and apparatus for secure traffic light interruption. A purpose of this invention is to allow for the use of a secure system to allow the interruption of the traffic light signals by emergency (and other authorized) vehicles. An objective of this invention is to allow for the use of a more secure system than the currently installed strobe only traffic light interruption (changing) systems. This invention integrates additional wireless technologies to assure that only authorized users trigger the traffic light changes that typically make it safer for emergency vehicles when they approach a traffic light.
