Abstract

Disclosed are systems and methods for implementing an electronic tollway barrier system. Exemplary systems and methods use positive vehicle identification at progressive monitoring locations to determine whether a vehicle has illegally entered a controlled lane across the electronic barrier, ensure that toll locations are not circumvented, and automatically issue citations to violators of the electronic barrier.

Claims

1. An electronic barrier and enforcement system comprising:

a processor;

a memory; and

a plurality of sensing devices located in series along one or more lanes of travel of a roadway system and operably connected to the processor, wherein at least a portion of the plurality of sensing devices are configured to detect a presence of each of one or more vehicles in the one or more lanes of the roadway system;

wherein said processor is configured to determine whether one of said one or more vehicles that is detected by a first sensing device of the at least a portion of the plurality of sensing devices is also detected by at least a second sensing device of the at least a portion of the plurality of sensing devices.

2. The system of claim 1, further comprising one or more identity devices, wherein the one or more identity devices are configured to individually identify each of said one or more vehicles detected by each of the at least a portion of the plurality of sensing devices.

3. The system of claim 2, wherein the at least a portion of the plurality of sensing devices further comprise the one or more identity devices.

4. The system of claim 2, wherein the processor is further configured to determine if one of said one or more vehicles that is detected by the first sensing device of the at least a portion of the plurality of sensing devices is not detected by the second sensing device of the at least a portion of the plurality of sensing devices, then the identity of the one of said one or more vehicles is recorded in the memory by the processor for use in an enforcement action or for toll collection.

5. The system of claim 2, wherein the first sensing device is an entrance sensing device for detecting the one or more vehicles entering a designated section of the said one or more lanes of travel of the roadway system and the second sensing device is an exit sensing device for detecting the one or more vehicles exiting the designated section of the said one or more lanes of travel of the roadway system.

6. The system of claim 5, wherein if one of said one or more vehicles that is detected by the entrance sensing device is not detected by the exit sensing device, then the identity of the one of said one or more vehicles is recorded in the memory by the processor for use in an enforcement action or for toll collection.

7. The system of claim 5, wherein if one of said one or more vehicles that is detected by the exit sensing device is not detected by the entrance sensing device, then the identity of the one of said one or more vehicles is recorded in the memory by the processor for use in an enforcement action or for toll collection.

8. The system of claim 5, further comprising a third sensing device of the at least a portion of the plurality of sensing devices, wherein the third sensing device is an intermediate sensing device located between the entrance sensing device and the exit sensing device and the intermediate sensing device is for detecting the one or more vehicles traveling in the designated section of the said one or more lanes of travel of the roadway system.

9. The system of claim 8, wherein if one of said one or more vehicles that is detected by the intermediate sensing device is not detected by the exit sensing device, then the identity of the one of said one or more vehicles is recorded in the memory by the processor for use in an enforcement action or for toll collection.

10. The system of claim 8, wherein if one of said one or more vehicles that is detected by the intermediate sensing device is not detected by the entrance sensing device, then the identity of the one of said one or more vehicles is recorded in the memory by the processor for use in an enforcement action or for toll collection.

11. The system of claim 2, wherein the one or more identity devices are comprised of one or more cameras for capturing an image of a vehicle.

12. The system of claim 2, further comprising:

a transportation operations database that comprises roadway segment information including one or more electronic barrier entry points and corresponding electronic barrier exit points, roadway operating conditions, and roadway segment toll price; and

a vehicle registration database that links vehicle identity information to a registered vehicle owner or other designee;

wherein the processor is configured to compare the presence of each of one or more vehicles in the one or more lanes of the roadway system to the transportations operations database and whether one of said one or more vehicles that is detected by a first sensing device of the at least a portion of the plurality of sensing devices is also detected by at least a second sensing device of the at least a portion of the plurality of sensing devices to determine when a vehicle has illegally crossed into the one or more lanes of the roadway system; and

wherein the vehicle identity information is compared to the vehicle registration database to determine the registered owners of the one or more vehicles in the one or more lanes of the roadway system and to issue a citation to the registered vehicle owner of the one or more vehicles in the one or more lanes of the roadway system.

13. The system of claim 12 wherein the electronic barrier entry and exit points can be flexibly configured and the electronic barrier can be shifted to cover as many lanes of a multi-lane roadway system as desired.

14. The system of claim 1, wherein electronic barrier locations comprising identification of the one or more lanes of the roadway system and electronic barrier entry points and corresponding electronic barrier exit points are communicated to drivers of vehicles via variable message signs.

15. The system of claim 1, wherein electronic barrier locations comprising identification of the one or more lanes of the roadway system and electronic barrier entry points and corresponding electronic barrier exit points are communicated to drivers of vehicles via an internet site and to an in-vehicle display system or to an hand-held device.

16. A method for electronic barrier and automated enforcement comprising:

defining an electronic barrier comprised of segments of one or more lanes of a roadway system and electronic barrier entry points and corresponding electronic barrier exit points;

detecting a presence of each of one or more vehicles in the electronic barrier;

identifying each of said one or more vehicles detected in the electronic barrier; and

determining whether each of said one or more vehicles has entered or exited the electronic barrier at an impermissible location.

17. The method of claim 16 further comprising:

identifying a registered vehicle owner for at least one of said one or more vehicles that has entered or exited the electronic barrier at an impermissible location; and

automated issuance of an electronic citation and missed toll collection to the registered vehicle owner.

18. The method of claim 16, wherein identifying each of said one or more vehicles detected in the electronic barrier comprises capturing an image of a vehicle.

19. The method of claim 16, wherein the electronic barrier can be flexibly configured and the electronic barrier can be shifted to cover as many lanes of a multi-lane roadway system as desired.

20. The method of claim 16, wherein electronic barrier locations are communicated to drivers of vehicles via variable message signs.

21. The method of claim 16, wherein electronic barrier locations are communicated to drivers of vehicles via an internet site and to an in-vehicle display system.
