Abstract

A traffic entity, such as a passenger car, is warned that a situation requiring the change of driving mode will be required. The traffic entity is alerted to the presence of a second traffic entity, such as an emergency vehicle which requires the moving traffic entity to change its movement when it is proximate to the second traffic entity. The alert is changed, such as by increasing the intensity of visible signals, as the distance between the moving traffic entity and the second traffic entity decreases or the closing speed between the two entities increases, and the mode of the alert is changed, such as from visible to audible, as the distance between the entities further decreases or the closing speed further increases. A variety of traffic entities are accommodated by the system.

Claims

1. A system for warning a traffic entity that a situation requiring the change of driving mode will be required comprising:

A) a first traffic entity which will affect the movement of another traffic entity, the first entity having a transmitter therein which transmits a unique warning signal over the air;

B) a second traffic entity which will have its traffic movement affected by the presence of the first entity, the second traffic entity including a receiver which will receive a warning signal from the transmitter in the first entity when the first and second entities are proximate to each other, the receiver including

(1) a proximity system which generates a proximity signal upon receipt of the warning signal, the proximity signal increasing in strength as the first and second entities approach each other,

(2) a first warning system associated with a first type of traffic entity, the first warning system being connected to the proximity system to receive a proximity signal generated by the first type of traffic entity and including first circuitry for generating a first warning signal that changes as the proximity signal strength associated with the first traffic entity increases, the first warning system further including second circuitry for generating a second warning signal that differs from the first warning signal of the first warning system and changes as the proximity signal strength associated with the first type of traffic entity further increases,

(3) a second warning system associated with a second type of traffic entity, the second warning system being connected to the proximity system to receive a proximity signal generated by the second type of traffic entity and including first circuitry for generating a first warning signal that changes as the proximity signal strength associated with the second traffic entity increases, the second warning system further including second circuitry for generating a second warning signal that differs from the first warning signal of the second warning system and changes as the proximity signal strength associated with the second type of traffic entity further increases,

(4) a third warning system associated with a third type of traffic entity, the third warning system being connected to the proximity system to receive a proximity signal generated by the third type of traffic entity and including first circuitry for generating a first warning signal that changes as the proximity signal strength associated with the third traffic entity increases, the third warning system further including second circuitry for generating a second warning signal that differs from the first warning signal of the third warning system and changes as the proximity signal strength associated with the third type of traffic entity further increases, and

(5) a mute circuit for disabling the second warning signal from any warning system.

2. The system defined in claim 1 wherein each of the first warning systems includes signal lights.

3. The system defined in claim 2 wherein each of the second warning systems includes an audible signal generator.

4. The system defined in claim 3 wherein the receiver further includes a mute circuit connected to the audible signal generator.

5. A method for warning a traffic entity that a situation requiring the change of driving mode will be required comprising:

A) alerting a moving traffic entity to the presence of a second traffic entity;

B) requiring the moving traffic entity to change its movement when it is proximate to the second traffic entity;

C) changing the alert as the distance between the moving traffic entity and the second traffic entity decreases or as the relative speed between the moving traffic entity and the second traffic entity changes; and

D) changing the alert by changing the mode of the alert as the distance and/or speed of the moving traffic entity further changes with respect to the second traffic entity.

6. The method defined in claim 5 wherein the mode of the alert is changed from visible to audible.

7. The method defined in claim 6 wherein the second traffic entity is moving.

8. The method defined in claim 6 wherein the second traffic entity is stationary.

9. The method defined in claim 6 further including a plurality of different traffic entities and providing a separate and unique alert for each traffic entity.

10. The method defined in claim 5 wherein the alert is changed by increasing or decreasing the intensity of the alert.
