Abstract

A traffic monitoring and notification system for vehicles includes road devices to be spaced apart along a road, and a traffic management controller. A portion of the vehicles may carry an electronic device that transmits an electronic address associated therewith. Each road device detects vehicles traveling on the road, determines if each detected vehicle is carrying an electronic device, and if so, then detects the electronic address associated therewith. A vehicle detection signal is transmitted based on each detected vehicle, and an electronic address signal is transmitted based on each detected electronic address. The traffic management controller receives the vehicle detection signals and the electronic address signals, determines a traffic pattern of the vehicles on the road based on the vehicle detection signals, and transmits a respective travel notification signal to each electronic device transmitting the electronic address associated therewith to provide travel information to a driver.

Claims

1. A traffic monitoring and notification system for vehicles, with a portion of the vehicles each carrying an electronic device comprising a transceiver configured to transmit an electronic address associated therewith, and notification circuitry coupled to the transceiver, the traffic monitoring and notification system comprising:

a plurality of road devices to be spaced apart and fixed along a surface of a road, each road device comprising

a vehicle proximity detector configured to detect vehicles traveling on the road,

a transceiver configured to determine if each detected vehicle is carrying an electronic device, and if so, then detect the electronic address associated therewith,

a controller coupled to said vehicle proximity detector and configured to provide for transmission a vehicle detection signal based on each detected vehicle, and coupled to said transceiver and configured to provide for transmission an electronic address signal based on each detected electronic address; and

a traffic management controller configured to

receive the vehicle detection signals and the electronic address signals from said plurality of road devices,

determine a traffic pattern of the vehicles on the road based on the vehicle detection signals, and

transmit a respective travel notification signal to the transceiver of each electronic device transmitting the electronic address associated therewith, with the travel notification signal being used to provide travel information to a driver via the notification circuitry coupled to the transceiver.

2. The traffic monitoring and notification system according to claim 1 wherein said traffic management controller is further configured to determine a speed of each detected vehicle carrying an electronic device based on the received electronic address signals associated therewith.

3. The traffic monitoring and notification system according to claim 1 wherein the electronic address signal comprises a MAC address.

4. The traffic monitoring and notification system according to claim 1 wherein the notification circuitry comprises a display, with the travel notification being provided to the driver by at least one of a text message, an image message and a video message.

5. The traffic monitoring and notification system according to claim 1 wherein the notification circuitry comprises a speaker, with the travel notification being provided to the driver as an audio message.

6. The traffic monitoring and notification system according to claim 1 wherein the travel information comprises at least one of travel times, traffic delays, lane closures, route detours, and evacuation routes.

7. The traffic monitoring and notification system according to claim 1 further comprising at least one relay hub configured to relay the vehicle detection signals and the electronic address signals from said plurality of road devices to said traffic management controller.

8. The traffic monitoring and notification system according to claim 1 further comprising at least one traffic notification dissemination device configured to relay the travel notification signals from said traffic management controller to each detected vehicle carrying an electronic device.

9. The traffic monitoring and notification system according to claim 1 wherein said plurality of road devices is configured as a mesh network, with each road device comprising a transceiver configured to relay the vehicle detection signals and the electronic address signals from one adjacent road device to another adjacent road device.

10. The traffic monitoring and notification system according to claim 9 wherein the transceiver in each electronic device comprises a Bluetooth™

transceiver; and

wherein said transceiver in each road device comprises a Bluetooth™
