Abstract

A traffic informational system provides information to traffic moving along a road and may include a plurality of traffic information devices mountable to the road, each having an integral power producing source, at least a first set of illumination sources, and a wireless communications subsystem. The traffic informational system may further include at least a first external control device comprising at least one antenna and a transmitter communication wirelessly with the traffic information devices and/or with one another. The traffic information device may communicate with one another, and may include sensor for sensing ambient conditions. The system employs various approaches to reducing power consumption and improving communications, and is suitable for a wide range of applications, including use in remote environments.

Claims

1. A traffic display network comprising:

a plurality of remotely-programmable traffic control devices each having an externally-visible display capable of generating at least one signal to oncoming traffic;

a communications system capable of communicating remote programming instructions to the plurality of remotely-programmable traffic control devices; and

a storage storing a list of network addresses of the remotely-programmable traffic control devices included in the traffic display network,

the traffic display network uses the list of network addresses to automatically coordinate at least one timing parameter of the remotely-programmable traffic control devices.

2. The traffic display network of claim 1, the display network being configured to alternate between a plurality of modes.

3. The traffic display network of claim 2, the plurality of modes including at least one of the modes selected from the group consisting of a passive mode, an active mode, a service mode, a sleep mode, a testing mode, and a servicing mode.

4. The traffic display network of claim 1, the communication system being capable of coordinating the operations of the plurality of the remotely-programmable traffic control devices.

5. The traffic display network of claim 1 where the control system is configured to set at least one of the plurality of the remotely-programmable traffic control devices to a one of a plurality of traffic signals.

6. The traffic display network of claim 1 wherein the remotely-programmable traffic control devices further comprise a power producing source capable of generating power for operation of the remotely-programmable traffic control device.

7. The traffic display network of claim 1:

wherein the remotely-programmable traffic control devices further comprise a control system being capable of being remotely programmed, where the communications system is capable of communicating to the control system programming instructions received through Internet.

8. The traffic display network of claim 1, further configured so that a wireless network communicates the programming instructions from the Internet to the traffic display network.

9. The traffic display network of claim 8 where the communications system is further capable of uploading data to the wireless network.

10. The traffic display network of claim 1 where the communications system is capable of communicating data to the Internet.

11. The traffic display network of claim 6 where the power producing source comprises at least one solar panel.

12. The traffic display network of claim 1 where the communication system is configured to receive signals from the at least one remotely-programmable traffic control device.

13. The traffic display network of claim 1 where the communication system operates continuously.
