Abstract

The present invention relates to a device for detecting and identifying school bus stop arm violations. The device includes a sensor positionable on a school bus for detecting the presence of a moving vehicle in a violation zone adjacent to the school bus. A detection mechanism detects the extension of the stop arm on the school bus. A control unit is operable with the sensor and the detection mechanism and provides a control signal indicating the presence of a vehicle in the violation zone when the stop arm is extended. A camera which is responsive to the control signal photographs the moving vehicle in the violation zone.

Claims

1. A device for identifying school bus stop arm violations wherein a moving vehicle enters a violation zone adjacent the school bus when a school bus stop arm is extended, the device comprising:

a control unit positionable on the school bus for providing a control signal when the stop arm is extended; and

a camera positionable on the school bus and responsive to the control signal for photographing the moving vehicle in the violation zone and the extended school bus stop arm.

2. The device of claim 1, further comprising a manually operated trigger switch positioned between the control unit and the camera to provide a time delay in the control signal activation of the camera.

3. The device of claim 1, further comprising stop arm detecting means for detecting the extension of the stop arm on the school bus, the control unit being operable with the stop arm detecting means such that the camera is enabled only when the stop arm detecting means detects the extension of the stop arm.

4. The device of claim 3, wherein the stop arm detecting means includes means for detecting when a door handle of the school bus is moved to open the door on the school bus and wherein the stop arm is extended when the door handle is moved.

5. The device of claim 4, wherein the means for detecting the opening of the school bus door includes a switch operable with the school bus door handle such that when the door handle is closed the switch is open and then the door handle is open the switch is closed.

6. The device of claim 3, wherein the stop arm detecting means is positioned on the stop arm.

7. The device of claim 6, wherein the stop arm detecting means is a push button switch operable with the stop arm such that when the stop arm is extended the switch is closed and when the stop arm is retracted the switch is open.

8. The device of claim 1, wherein the control unit is powered in association with and thereby operable with a flasher control unit on the school bus.

9. The device of claim 1, further comprising a protective box for housing the camera, the protective box being positioned on an exterior side of the school bus such that the camera photographs vehicles in the violations zone and the extended stop arm.

10. The device of claim 9, wherein the protective box further includes defogging means for preventing the accumulation of moisture within the protective box which interferes with the camera.

11. The device of claim 9, wherein the protective box is accessible from an interior of the school bus.

12. The device of claim 9, further comprising a splash guard for protecting a face of the protective box, the splash guard being movable away from the face to permit the camera to photograph vehicles in the violation zone and the extended stop arm.

13. The device of claim 12, further comprising sensor means for providing an audible signal indicative of a vehicle in the violation zone so that a bus driver is alerted to activate the manually operated trigger switch.

14. The device of claim 1, further comprising a flood light providing light to the violation zone.

15. A method for identifying school bus stop arm violations wherein a moving vehicle enters a violation zone adjacent the school bus when a school bus stop arm is extended, comprising:

providing a control signal when the stop arm is extended; and

photographing the moving vehicle in the violation zone together with the extended school bus stop arm in response to the control signal.

16. The method of claim 15 further comprising detecting the extension of the stop arm on the school bus thereby enabling the control signal.

17. The method of claim 15, wherein the providing step further includes triggering a manually operated switch enabling the transmission of the control signal to a camera for photographing the vehicle.

18. The method of claim 15, further comprising providing a protective box for housing a camera, the protective box being positioned on an exterior side of the school bus such that the camera photographs vehicles in the violation zone and the extended stop arm.

19. The method of claim 18, further comprising providing defogging means for preventing the accumulation of moisture within the protective box which interferes with the photographing of the moving vehicle.

20. The method of claim 18, further comprising providing a splash guard for protecting a face of the protective box, and selectively moving the splash guard away from the face to permit the camera to photograph vehicles in the violation zone and the extended stop arm.
