Infrastructure-based collision warning using artificial intelligence
First Claim
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.

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.

24. A method of reducing a probability of a collision in an intersection having a traffic signal, the method comprising the steps of:
-
determining vehicle data for a vehicle approaching the intersection, the vehicle data including vehicle speed and vehicle position;
comparing vehicle data and signal phase to a pattern analysis of stored data, the stored data including previous vehicle data relating to vehicles previously passing through the intersection;
predicting a signal violation using the comparison of the vehicle data to a pattern analysis of stored data; and
providing a modified signal operation if a signal violation is predicted, so as to reduce the probability of the collision. - View Dependent Claims (25, 26, 27)
