Abstract

A vehicular traffic monitoring system which is capable of providing a complete monitoring system in an assembly capable of being mounted in a plane above or beside a roadway in order to monitor substantially all factors of interest with respect to approaching and receding vehicular traffic along the roadway below.

Claims

1. A traffic monitoring system for a roadway comprising:

an enclosure having opposite first approaching and second receding vehicle end portions thereof;

first and second scene cameras positioned adjacent said first and second end portions of said enclosure respectively;

first and second automatic number plate recognition (ANPR) cameras respectively associated with said first and second scene cameras;

first and second laser sensors respectively associated with said first and second scene and ANPR cameras; and

a controller operatively coupled to said first and second scene and ANPR cameras and said first and second laser sensors.

2. The traffic monitoring system of claim 1 further comprising first and second illumination sources associated with said first and second scene cameras.

3. The traffic monitoring system of claim 1 further comprising first and second alignment cameras associated with said first and second laser sensors.

4. The traffic monitoring system of claim 1 wherein said system is positioned in a plane above said roadway.

5. The traffic monitoring system of claim 1 wherein said system is positioned at a roadside of said roadway.

6. The traffic monitoring system of claim 1 wherein said first and second laser sensors comprise TruSense®

T100 and T200 units respectively.

7. The traffic monitoring system of claim 1 wherein said system is capable of operation to determine vehicle speed on said roadway utilizing at least one of said first and second laser sensors.

8. The traffic monitoring system of claim 1 wherein said system is capable of operation to determine the distance between vehicles on said roadway utilizing at least one of said first and second laser sensors.

9. The traffic monitoring system of claim 1 wherein said system is capable of operation to determine one of vehicle profile or classification utilizing at least one of said first and second laser sensors.

10. The traffic monitoring system of claim 1 wherein said system is capable of operation to determine the occupancy of a vehicle on said roadway utilizing at least one of said first and second scene cameras.

11. The traffic monitoring system of claim 1 wherein said system is capable of operation to determine one of length or height of a vehicle on said roadway utilizing at least one of said first and second laser sensors.

12. The traffic monitoring system of claim 1 wherein said system is capable of operation to determine one of time or distance since a preceding vehicle has been sensed by said system.

13. The traffic monitoring system of claim 1 wherein said system is capable of operation to provide an indication of a license plate of a vehicle of interest utilizing at least one of said first and second ANPR cameras.

14. The traffic monitoring system of claim 1 wherein said system is capable of operation to provide an indication of a vehicle traveling a wrong way on said roadway utilizing said first and second scene cameras.
