Abstract

A collision avoidance system includes a sensor adapted to detect at least one vehicle in the vicinity of a predetermined area and generate target data relating to the at least one vehicle. An awareness engine receives the target data and evaluates the target data for a threat of a collision. An alerting system is adapted to alert the at least one vehicle in the event of a threat of a collision, the alerting system being activated by the awareness engine.

Claims

1. A collision avoidance system, comprising:

a sensor adapted to;

detect at least one vehicle in the vicinity of a predetermined area, and

generate target data relating to the at least one vehicle;

an awareness engine adapted to;

receive the target data from the sensor, and

evaluate the target data for a threat of a collision; and

an alerting system adapted to alert the at least one vehicle in the event of a threat of a collision, the alerting system being activated by the awareness engine.

2. The collision avoidance system of claim 1 wherein the sensor is configured to detect Automatic Dependent Surveillance-Broadcast (ADS-B) signals transmitted by the at least one vehicle.

3. The collision avoidance system of claim 1 wherein the sensor is configured to:

receive at least one of radar data, sonar data, proximity sensor data, and data from communication networks, the radar data, sonar data, proximity sensor data, and data from communication networks relating to the at least one vehicle; and

generate target data relating to the at least one vehicle.

4. The collision avoidance system of claim 1 wherein the sensor comprises a plurality of sensors.

5. The collision avoidance system of claim 1 wherein the awareness engine comprises an evaluation subsystem, the evaluation subsystem being adapted to:

receive target data,

determine the risk of a collision with the at least one vehicle, and

provide evaluation results to the alerting system.

6. The collision avoidance system of claim 5, wherein the at least one vehicle comprises a plurality of vehicles, the evaluation subsystem being further adapted to determine, from corresponding target data, the risk of a collision between the vehicles.

7. The collision avoidance system of claim 5 wherein the alerting system is activated to issue a warning when the risk of a collision exceeds a predetermined threshold.

8. The collision avoidance system of claim 5 wherein the evaluation results include information relating to at least one of a graded level of risk, whether the risk of a collision is increasing or decreasing, and timing aspects of the risk.

9. The collision avoidance system of claim 5 wherein the evaluation subsystem is adapted to compare target data relating to the at least one vehicle with predetermined obstruction data.

10. The collision avoidance system of claim 1 wherein the alerting system further comprises a visually perceivable indicator.

11. The collision avoidance system of claim 10 wherein at least one operating characteristic of the indicator is altered in the event of a threat of a collision.

12. The collision avoidance system of claim 1 wherein the alert is in the form of an electronic communication.

13. The collision avoidance system of claim 1 wherein the alert is in the form of an aural signal.

14. The collision avoidance system of claim 1, further including a communication interface adapted to receive data from at least one source external to the collision avoidance system.

15. The collision avoidance system of claim 14 wherein the communication interface is further adapted to transmit data external to the system.

16. The collision avoidance system of claim 1 wherein:

the sensor is configured to detect Automatic Dependent Surveillance-Broadcast (ADS-B) signals transmitted by the at least one vehicle; and

the alerting system includes at least one taxiway light positioned proximate a hold short threshold of an aircraft runway,

at least one operating characteristic of the at least one taxiway light being altered when a target vehicle is detected proximate the aircraft runway.

17. The collision avoidance system of claim 1 wherein the awareness engine is adapted to evaluate the target data for a threat of a collision between the at least one vehicle and an obstacle.

18. The collision avoidance system of claim 1 wherein the alerting system includes a visually perceivable indicator, the indicator being directed toward the at least one vehicle in the event of a threat of a collision.

19. A collision avoidance system, comprising:

an Automatic Dependent Surveillance-Broadcast (ADS-B) receiver;

an ADS-B transmitter;

an alerting system adapted for mounting to an obstruction; and

an ADS-B processor coupled to at least one of the ADS-B receiver, the ADS-B transmitter and the alerting system,

the operating characteristics of at least one of the ADS-B transmitter and the alerting system being controlled by the ADS-B processor.

20. The collision avoidance system of claim 19 wherein the ADS-B receiver, ADS-B transmitter, and ADS-B processor are adapted to function as a repeater.

21. A collision avoidance system, comprising:

an obstruction light adapted for mounting to an obstruction; and

an Automatic Dependent Surveillance-Broadcast (ADS-B) transmitter adapted to continuously broadcast a signal having information relating to the obstruction,

the obstacle being indicated in the broadcast signal as a terrain alert.
