Claim One:
1. An apparatus for controlling a traffic signal at an intersection of a first route and a second route, the traffic signal providing a first signal to a first vehicle on the first route, and a second signal to a second vehicle on the second route, the apparatus including: a vehicle sensor, operable to provide vehicle data for the first vehicle, the vehicle data including vehicle speed and vehicle position; an ambient condition sensor, providing ambient condition data for the intersection; and a signal controller controlling the first signal and the second signal, the signal controller including an artificial intelligence based situational analyzer, receiving the vehicle data and the ambient condition data, the artificial intelligence based situational analyzer determining a stopping deceleration necessary for the first vehicle to avoid violating the first signal, and providing a violation prediction if the stopping deceleration exceeds a threshold deceleration, the threshold deceleration being modified by ambient condition data; the violation prediction causing a modification of the control signal so as to reduce the probability of a collision between the first vehicle and the second vehicle.
