ABSTRACT:
An improved apparatus for controlling a traffic signal at an intersection includes a signal controller having an artificial intelligence based situational analyzer. The signal controller receives vehicle data related to the speed and position of vehicles approaching the intersection, and optionally time and ambient condition data. If the artificial intelligence based situational analyzer predicts a signal violation, operation of the traffic signal is modified to reduce the probability of a vehicular collision.
