Abstract

The system and method disclosed utilize a smart metering system that combines real-time traffic data and statistical traffic models to control vehicle flow. Also disclosed are a system and method for using dual-use traffic lanes that function as regular traffic lanes under regular traffic conditions and as emergency traffic lanes in an emergency. Vehicle speed control devices can be used to prevent or break up slower traffic waves when they occur.

Claims

1. A traffic control system for a highway having a series of on-ramps along the length of the highway for allowing access to the highway, the system comprising:

a smart metering system that controls access to the highway at the on-ramps based on real-time traffic data and stored traffic data.

2. The traffic control system of claim 1, further comprising a plurality of vehicle speed control devices for preventing stop-and-go traffic patterns on a highway.

3. The traffic control system of claim 1, further-comprising at least one dual-use traffic lane that functions as a regular traffic lane under regular traffic conditions and as an emergency traffic lane in an emergency.

4. The traffic control system of claim 3, wherein the at least one dual-use traffic lane is converted from a regular traffic lane to an emergency traffic lane by a plurality of dual-use lane indicators placed along the length of the highway.

5. The traffic control system of claim 4, wherein the dual-use lane indicators are switched from a regular mode to an emergency mode by the presence of an activated emergency vehicle.

6. The traffic control system of claim 4, wherein the dual-use lane indicators are switched from a regular mode to an emergency mode by a central processing system that is able to receive data regarding the location of an activated emergency vehicle.

7. The traffic control system of claim 4, further comprising stopped vehicle sensors able to detect the presence of a stopped vehicle in the dual-use lane.

8. The traffic control system of claim 7, wherein the dual-use lane indicators are switched from a regular mode to an emergency mode by the presence of a stopped vehicle in the dual-use lane.

9. The traffic control system of claim 7, wherein the stopped vehicle sensors are able to alert authorities to the presence of a stopped vehicle.

10. The traffic control system of claim 1, wherein the smart metering system comprises a central processing system connected with (a) a plurality of on-ramp access gates located at the on-ramps of the highway and (b) a plurality of traffic variable sensors along the length of the highway.

11. The traffic control system of claim 10, wherein the central processing system controls the rate of opening of the on-ramp access gates to achieve the maximum vehicle density allowed while maintaining maximum vehicle throughput.

12. The traffic control system of claim 11, wherein the central processing system collects and processes traffic data collected by the traffic variable sensors, and controls the rate of opening of the on-ramp access gates based in part on data collected by the traffic variable sensors.

13. The traffic control system of claim 11, wherein the central processing system includes database storage containing stored traffic data, and controls the rate of opening of the on-ramp access gates based in part on the stored traffic data.

14. The traffic control system of claim 13, wherein the stored traffic data comprises historic traffic data.

15. The traffic control system of claim 12, wherein the stored traffic data comprises statistical traffic models.

16. The traffic control system of claim 15, wherein the statistical traffic models include data comprising the distribution of exits to be used by vehicles from each on-ramp.

17. The traffic control system of claim 10, wherein the on-ramp access gates further comprise at least one vehicle queue sensor for sensing how many vehicles are waiting at the on-ramp access gate.

18. The traffic control system of claim 17, wherein the central processing system controls the rate of opening of the on-ramp access gates based in part on the data collected by the vehicle queue sensors.

19. The traffic control system of claim 11, wherein a fee-based rate for on-ramp gate opening and a free rate for on-ramp gate opening are established, and the central processing system controls the rate of opening for each to achieve the maximum vehicle density allowed while maintaining maximum vehicle throughput.

20. The traffic control system of claim 10, wherein the on-ramp access gates further comprise a message board.

21. The traffic control system of claim 10, wherein the traffic variable sensors detect traffic data and deliver the data to the central processing system in real-time.

22. The traffic control system of claim 11, wherein the central processing system improves the rate of opening of the gates by analyzing prior rates against actual prior vehicle throughput.

23. The traffic control system of claim 1, further comprising a plurality of vehicle speed control devices.

24. The traffic control system of claim 23, wherein the plurality of vehicle speed control devices comprise a series of laterally spaced vehicles.

25. The traffic control system of claim 23, wherein the plurality of vehicle speed control devices comprise a series of indicators.

26. The traffic control system of claim 23, wherein the plurality of vehicle speed control devices are employed when stop-and-start traffic patterns are detected.

27. The traffic control system of claim 23, wherein the plurality of vehicle speed control devices prevent vehicles from going above a maximum calculated speed.

28. The traffic control system of claim 25, wherein the indicators are lights.

29. A method of controlling traffic on a highway comprising the steps of obtaining real-time traffic data, analyzing real-time traffic data in light of historic traffic data, and controlling access to the highway based on the analysis.

30. The method of claim 29, wherein the step of controlling access to the highway includes use of meters at on-ramps of the highway.

31. The method of claim 29, further comprising the step of controlling vehicle density on a highway by controlling vehicle pace.

32. The method of claim 29, further comprising the step of using the highway emergency lane as a dual-use lane such that the dual-use lane is used as a regular traffic lane unless an emergency takes place.

33. The method of claim 32, wherein the step of converting the dual-use lane from a regular traffic lane to an emergency lane is accomplished by signaling vehicle drivers to exit the dual-use lane when an emergency takes place.
