Abstract

An electronic traffic alert system for communicating with an emergency vehicle and a centralized traffic control station includes a traffic display having a screen for displaying graphics and configured to hold a plurality of modules. The modules are of substantially uniform shape, such that individual modules are interchangeably connectable to the traffic display, and the plurality of modules are mounted below the screen so that at least one of them extends below the traffic display. The traffic display also includes a central processor in communication with the plurality of modules and the screen, with the central processor configured to display a predetermined graphic on the screen according to input from at least one of the plurality of modules, and an interface for transmitting traffic-related information to the traffic display from and a centralized traffic control station.

Claims

1. An electronic traffic alert system for communicating with an emergency vehicle and a centralized traffic control station comprising:

a traffic display comprising a screen for displaying graphics, the traffic display configured to hold a plurality of modules;

the plurality of modules having a substantially uniform shape, such that individual modules are interchangeably connectable to the traffic display;

the plurality of modules mounted below the screen such that at least one of the plurality of modules extends below the traffic display;

wherein one of the plurality of modules comprises a distance detector for detecting objects persisting under the traffic display;

the traffic display further comprising a central processor in communication with the plurality of modules and the screen, the central processor configured to display a predetermined graphic on the screen according to input from at least one of the plurality of modules; and

an interface to transmit traffic-related information between the traffic display and a centralized traffic control station, thereby allowing control of the traffic display by the centralized traffic control station.

2. The electronic traffic alert system of claim 1 further comprising a connector strip inside the traffic display for removably connecting each of the plurality of modules for ease of service and replacement.

3. The electronic traffic alert system of claim 1 wherein multiple traffic displays are located at a single intersection and are wirelessly connected for coordinating messages displayed on the screen of each of the multiple traffic displays.

4. The electronic traffic alert system of claim 1 wherein one of the plurality of modules comprises an infrared vehicle detector for detecting approaching emergency vehicles.

5. The electronic traffic alert system of claim 1 wherein one of the plurality of modules comprises a light sensor and the central processor is configured to automatically change a brightness level of the screen under changing ambient light conditions.

6. The electronic traffic alert system of claim 1 wherein one of the plurality of modules comprises a parking module in communication with a parking server through a cellular network, the parking module configured to receive available parking space information for display on the screen.

7. The electronic traffic alert system of claim 1 wherein the central processor is in communication with a pedestrian crossing monitor that provides the status of pedestrian crossing signals at an intersection where the traffic display is installed.

8. The electronic traffic alert system of claim 7 wherein one of the plurality of modules comprises a pedestrian module for displaying on the screen pedestrian crossing signal information corresponding to the status.

9. The electronic traffic alert system of claim 1 wherein one of the plurality of modules comprises a feature selected from the group consisting of loudspeaker, camera, thermometer, air quality sensor, and back-up battery pack.

10. The electronic traffic alert system of claim 1 wherein one of the plurality of modules is capable of receiving emergency-related information from a moving vehicle and thereafter causing the traffic display to indicate the direction of the vehicle to drivers travelling in a perpendicular direction.

11. The electronic traffic alert system of claim 1 wherein one of the plurality of modules is configured to receive GPS proximity information from a cell phone, wherein the central processor displays an alert on the screen corresponding to the cell phone.

12. The electronic traffic alert system of claim 1 wherein the traffic display is capable of receiving emergency-related information from the centralized traffic control station and thereafter displaying an alert to drivers regarding lane direction changes.

13. The electronic traffic alert system of claim 1 wherein the traffic display comprises a protective cowl at least partially around the screen.

14. The electronic traffic alert system of claim 1 wherein the traffic display comprises a bumper in front of the screen.

15. The electronic traffic alert system of claim 1 wherein the traffic display is mounted proximal a street sign, the traffic display further comprising a light for illuminating the street sign.

16. The electronic traffic alert system of claim 1 wherein the traffic display is configured for installation adjacent a second traffic display for creating an enlarged screen.

17. An electronic traffic alert system for communicating with an emergency vehicle and a centralized traffic control station comprising:

a traffic display comprising a screen displaying graphics, the traffic display configured to hold a plurality of modules;

the plurality of modules having a substantially uniform shape, such that individual modules are interchangeably connectable to the traffic display;

the plurality of modules mounted below the screen such that at least one of the plurality of modules extends below the traffic display;

the plurality of modules comprise infrared receiver, distance sensor light sensor, loudspeaker, camera, thermometer, air quality sensor, and back-up battery pack;

the traffic display further comprising a central processor in communication with the plurality of modules and the screen, the central processor configured to display a predetermined graphic on the screen according to input from at least one of the plurality of modules;

an interface to transmit traffic-related information between the traffic display and a centralized traffic control station, thereby allowing control of the traffic display by the centralized traffic control station; and

wherein multiple traffic displays are located at a single intersection and are wirelessly connected coordinating messages displayed on the screen of each of the multiple traffic displays.
