Method and apparatus for secure traffic light interruption
First Claim
1. A method for providing an interruption cycle for a traffic light system, the method comprising:
- recognizing a first signal from a signaling unit of a vehicle;
locking onto the first signal;
transmitting a second signal to the signaling unit of the vehicle;
receiving a third signal in response to the second signal;
determining if the third signal includes information validating the signaling unit of the vehicle as being authorized; and
,initiating the interruption cycle if the signaling unit is authorized.

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.
