Appl. No.:

15/840010

Inventors:

- Munich, DE
- Alpharelta GA, US
Andrew Valdez - Austin TX, US
Bradley Wehrwein - Princeton NJ, US

International Classification:

G08G 1/097

G08G 1/07

Abstract:

A traffic control monitoring and abnormality determination system and associated methods are disclosed for receiving and analyzing traffic controller input/output data during a learning phase to determine a model indicative of normal or healthy operation of the traffic controller in regulating traffic flow at an intersection and receiving and evaluating additional traffic controller input/output data against the model during an evaluation phase to determine whether an abnormality exists in operation of the traffic controller. If an abnormality is detected during the evaluation phase, the system may initiate a corrective action to resolve the abnormality such as sending an alarm signal to a traffic controller to cause the traffic controller to alter an operating state to resolve the abnormality.
