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. An airport traffic collision avoidance system, comprising:

an air and ground vehicle sensor configured to;

detect an Automatic Dependent Surveillance-Broadcast (ADS-B) signal transmitted by at least one vehicle in a vicinity of a predetermined area of an airport,

use the detected ADS-B signal to determine at least one of a position, direction, and velocity of the vehicle, and

generate a 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 with another ground or airborne vehicle, or an obstruction; and

an alerting system adapted to;

receive a command from the awareness engine, and

alert the at least one vehicle in the event of a threat of a collision in the predetermined area,

the alerting system being selectably activated by the command from the awareness engine.

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

receive the target data,

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

provide evaluation results to the alerting system.

3. The airport traffic collision avoidance system of claim 2, 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.

4. The airport traffic collision avoidance system of claim 2 wherein the alerting system is activated to issue a warning when the risk of a collision exceeds a predetermined threshold.

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

6. The airport traffic collision avoidance system of claim 5 wherein at least one operating characteristic of the indicator is altered in the event of a threat of a collision.

7. A collision avoidance system for a movable obstacle, comprising:

a sensor configured to;

detect an Automatic Dependent Surveillance-Broadcast (ADS-B) signal transmitted by at least one vehicle in a vicinity of a predetermined area of a movable obstacle,

use the detected ADS-B signal to determine at least one of a position, direction, and velocity of the vehicle, and

generate a 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 with the movable obstacle; and

an alerting system adapted to;

receive a command from the awareness engine, and

alert the at least one vehicle in an event of a threat of a collision with the movable obstacle,

the alerting system being selectably activated by the command from the awareness engine.

8. The collision avoidance system of claim 7 wherein the awareness engine comprises an evaluation subsystem, the evaluation subsystem being adapted to:

receive the target data,

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

provide evaluation results to the alerting system.

9. The collision avoidance system of claim 8, 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.

10. The collision avoidance system of claim 8 wherein the alerting system is activated to issue a warning when the risk of a collision exceeds a predetermined threshold.

11. The collision avoidance system of claim 7 wherein the alerting system further comprises a visually perceivable indicator.

12. The collision avoidance system of claim 11 wherein characteristics of the indicator are altered in a predetermined, visually perceivable manner.

13. The collision avoidance system of claim 12 wherein an intensity of the indicator is altered by the alerting system in the event of a threat of a collision with the movable obstacle.

14. The collision avoidance system of claim 12 wherein a color of the indicator is altered by the alerting system in the event of a threat of a collision with the movable obstacle.

15. The collision avoidance system of claim 12 wherein a flash rate of the indicator is altered by the alerting system in the event of a threat of a collision with the movable obstacle.

16. The collision avoidance system of claim 12 wherein an on-off duty cycle of the indicator is altered by the alerting system in the event of a threat of a collision with the movable obstacle.

17. The collision avoidance system of claim 12 wherein the indicator is aimed or directed in a predetermined manner in the event of a threat of a collision with the movable obstacle.

18. The collision avoidance system of claim 12 wherein an intensity of the indicator is increased in the event of a threat of a collision with the movable obstacle.
