High occupancy vehicle lane enforcement system using an information system for reduced false positives
First Claim
1. A computer-implemented method of enforcing traffic rule compliance, comprising:
- determining, via a processor, an HOV violation hypothesis, wherein the HOV violation hypothesis comprises a presumption as to whether a vehicle that is detected within a first HOV zone is complying with one or more HOV rules based on a determined observed passenger configuration associated with the vehicle;
retrieving, via the processor and from a data store, one or more data records associated with the vehicle, wherein the one or more data records include historical information identifying past compliance with or violation of HOV rules by the vehicle;
modifying, via the processor, the HOV violation hypothesis based on the historical information,receiving, via the processor, information indicating an actual passenger configuration associated with the vehicle; and
storing, via the processor and in the data store, an indication of accuracy associated with the HOV violation hypothesis as a result of comparing the observed passenger configuration to the actual passenger configuration associated with the vehicle.

Abstract
An upstream vehicle detection system captures images of a vehicle as it travels through a high occupancy vehicle (HOV) lane or high occupancy vehicle tolling (HOT) station and generates an hypothesis as to whether the vehicle is complying with HOV or HOT rules based on image analysis. A database of historical information about various vehicles'"'"' compliance with HOV or HOT rules is consulted to determine whether the vehicle has previously been identified as a potential violator and pulled over by law enforcement as a result. If the vehicle was previously pulled over by law enforcement and determined to be complying with HOV or HOT rules (a false positive), then the violation hypothesis may be weighted in favor of not pulling the vehicle over.

9. A system configured to enforce traffic rule compliance, comprising:
-
a processing system comprising one or more processors; a memory system comprising one or more computer-readable media, wherein the computer-readable media contain program instructions that, when executed by the processing system, cause the processing system to perform operations to; determine an HOV violation hypothesis, wherein the HOV violation hypothesis comprises a presumption as to whether a vehicle detected within a first HOV zone is complying with one or more HOV rules based on an observed passenger configuration associated with the vehicle; retrieve, from a data store, one or more data records associated with the vehicle, wherein the one or more data records include historical information identifying past compliance with or violation of HOV rules by the vehicle; modify the HOV violation hypothesis based on the historical information, receive information indicating an actual passenger configuration associated with the vehicle; and store, in the data store, an indication of accuracy associated with the HOV violation hypothesis as a result of comparing the observed passenger configuration to the actual passenger configuration associated with the vehicle. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer-implemented method of enforcing traffic rule compliance, comprising:
-
during a first window of time; determining, via a processor, a first HOV violation hypothesis, wherein the first HOV violation hypothesis comprises a presumption as to whether a vehicle detected within a first HOV zone is complying with one or more HOV rules based on a determined first observed passenger configuration associated with the vehicle; and storing, via the processor, the first HOV violation hypothesis in a data store; and during a second window of time subsequent to the first window of time; determining, via the processor, a second HOV violation hypothesis, wherein the second HOV violation hypothesis comprises a presumption as to whether the vehicle detected in the second HOV zone is complying with one or more HOV rules based on a determined second observed passenger configuration associated with the vehicle; retrieving, via the processor and from the data store, the first HOV violation hypothesis; and modifying, via the processor, the second HOV violation hypothesis based on the first HOV violation hypothesis. - View Dependent Claims (18, 19)
