Abstract

The present invention provides traffic lights comprising an LED panel for directing motor traffic, an LED panel for directing pedestrian traffic, an LED street sign, an LED panel for displaying an animated advertisement or important message, such as traffic conditions ahead, and a personal device interface providing two-way communication of information between the traffic light and at least one local user with a personal portable electronic device. The present invention also provides LED traffic lights that are capable of communicating approximately how much time remains before the traffic light changes from a signal directing motorists to proceed to a signal directing motorists to stop, and a personal device interface providing two-way communication of information between the traffic light and at least one local user with a personal portable electronic device.

Claims

1. A unitary traffic light apparatus comprising:

a primary traffic panel including a first matrix of multicolored LEDs, said primary traffic panel directing motor traffic;

a message panel coupled directly to said primary traffic panel, said message panel including a second matrix of multicolored LEDs, said message panel displaying information unrelated to the directing of traffic; and

a personal device interface providing two-way communication of information between said unitary traffic light apparatus and at least one local non-emergency user with a personal portable electronic device, said personal portable electronic device sends and receives information to and from said unitary traffic light apparatus regarding said information unrelated to the directing of traffic displayed on said message panel,

wherein said unitary traffic light apparatus is a column with at least three lateral sides, and wherein a plurality of said lateral sides comprise said primary traffic panel and said message panel.

2. The unitary traffic light apparatus of claim 1, wherein said primary traffic panel directs motor traffic by displaying images that communicate information relating to how much time remains before said primary traffic panel changes from a signal directing motorists to proceed to a signal directing motorists to stop.

3. The unitary traffic light apparatus of claim 1, further comprising means for causing said message panel to display messages provided over a computer communication network.

4. The unitary traffic light apparatus of claim 1, further comprising means for modifying a display scheme according to a special motif.

5. The unitary traffic light apparatus of claim 1, wherein said message panel includes means for displaying animated advertisements.

6. The unitary traffic light apparatus of claim 5, wherein said animated advertisements are provided over a computer communication network.

7. The unitary traffic light apparatus of claim 1, further comprising means for use as an information terminal.

8. The unitary traffic light apparatus of claim 1, further comprising means for use as a point-of-sales station.

15. The unitary traffic light apparatus of claim 1, 9, or 14, wherein said column is rectangular or triangular.

9. A unitary traffic light apparatus comprising:

a first matrix of multicolored LEDs, said first matrix directing motor traffic and providing a visual indicator of how much time remains before a traffic light signal displayed on said first matrix changes from a signal directing motorists to proceed to a signal directing motorists to stop;

a second matrix of multicolored LEDs coupled directly to said first matrix, said second matrix displaying information unrelated to the directing of motor traffic; and

a personal device interface providing two-way communication of information between said unitary traffic light apparatus and at least one local non-emergency user with a personal portable electronic device, said personal portable electronic device sends and receives information to and from said unitary traffic light apparatus regarding said information unrelated to the directing of traffic displayed on said second matrix,

wherein said unitary traffic light apparatus is a column with at least three lateral sides, and wherein a plurality of said lateral sides comprise said first matrix and said second matrix.

10. The traffic light apparatus of claim 9, wherein said visual indicator is a count-down timer.

11. The traffic light apparatus of claim 9, wherein said visual indicator is a shrinking stripe.

12. The traffic light apparatus of claim 9, wherein said visual indicator is a gradient horizontal strip.

13. The traffic light apparatus of claim 9, further comprising means for use as a point-of-sales station.

14. A unitary traffic light apparatus comprising:

a primary traffic panel including a first matrix of multicolored LEDs, said primary traffic panel directing motor traffic;

a message panel including a second matrix of multicolored LEDs, said message panel displaying information unrelated to the directing of traffic;

a pedestrian traffic panel including a third matrix of multicolored LEDs, said pedestrian traffic panel directing pedestrian traffic, wherein said pedestrian traffic panel, said primary traffic panel, and said message panel are directly coupled; and

a personal device interface providing a two-way communication of information between said message panel and at least one local non-emergency user with a personal portable electronic device, said personal portable electronic device sends and receives information to and from said unitary traffic light apparatus regarding said information unrelated to the directing of traffic displayed on said message panel,

wherein said unitary traffic light apparatus is a column with at least three lateral sides, and wherein a plurality of said lateral sides comprise said primary traffic panel and said message panel.

16. A unitary traffic light apparatus comprising:

a primary traffic panel including a first matrix of multicolored LEDs, said primary traffic panel directing motor traffic;

a message panel which includes a second matrix of multicolored LEDs, said message panel displaying information unrelated to the directing of traffic;

a spacer directly coupled between said primary traffic panel and said message panel; and

a personal device interface providing a two-way communication of information between said message panel and at least one local non-emergency user with a personal portable electronic device, said personal portable electronic device sends and receives information to and from said unitary traffic light apparatus regarding said information unrelated to the directing of traffic displayed on said message panel,

wherein said unitary traffic light apparatus is a rectangular column with four lateral sides, and wherein a plurality of said lateral sides comprise said primary traffic panel, said spacer, and said message panel.

17. A unitary traffic light apparatus comprising:

a primary traffic panel including a first matrix of multicolored LEDs, said primary traffic panel directing motor traffic;

a pedestrian traffic panel including a second matrix of multicolored LEDs, said pedestrian traffic panel directing pedestrian traffic;

a message panel including a third matrix of multicolored LEDs, said message panel displaying information unrelated to the directing of traffic;

a first spacer directly coupled between said primary traffic panel and said pedestrian traffic panel;

a second spacer directly coupled between said pedestrian traffic panel and said message panel; and

a personal device interface providing a two-way communication of information between said message panel and at least one local non-emergency user with a personal portable electronic device, said personal portable electronic device sends and receives information to and from said unitary traffic light apparatus regarding said information unrelated to the directing of traffic displayed on said message panel,

wherein said unitary traffic light apparatus is a rectangular colunin with four lateral sides, and wherein a plurality of said lateral sides comprise said primary traffic panel, said first spacer, said pedestrian traffic panel, said second spacer, and said message panel.

18. The unitary traffic light apparatus of claim 17, further comprising at least one street sign coupled to said first spacer.

19. The unitary traffic light apparatus of claim 18, wherein said at least one street sign comprises an LED panel.
