Stop alert warning system
First Claim
1. An on-site roadway warning system for alerting a driver of an approaching vehicle of a need to brake the vehicle, the warning system comprising:
- a transceiver for radiating electromagnetic energy toward the approaching vehicle and receiving reflected energy from the vehicle;
a processor associated with the transceiver for processing data about the reflected energy in relation to data about the radiated energy to yield data disclosing both range of the approaching vehicle from the transceiver and rate at which the vehicle is approaching the transceiver;
the processor containing stored data that correlates various combinations of range and speed that distinguish between combinations of potentially dangerous range and speed and combinations that are not potentially dangerous;
the processor operating to process the data disclosing range of the approaching vehicle from the transceiver and rate at which the vehicle is approaching the transceiver in relation to the stored data; and
a signaling device that is activated to signal the approaching vehicle when the processor determines that the data disclosing range of the approaching vehicle from the transceiver and rate at which the vehicle is approaching the transceiver correlates with stored data that identifies a potentially dangerous combination of range and rate.

Abstract
An on-site roadway warning system for alerting a driver of an approaching vehicle of a need to brake the vehicle. A transceiver radiates electromagnetic energy toward the approaching vehicle and receives reflected energy from the vehicle. A processor processes data about the reflected energy in relation to data about the radiated energy to yield data disclosing both range of the approaching vehicle from the transceiver and rate at which the vehicle is approaching the transceiver. The processor processes the data disclosing range of the approaching vehicle from the transceiver and rate at which the vehicle is approaching the transceiver in relation to the stored data, and activates a signaling device to signal the approaching vehicle when the data disclosing range of the approaching vehicle from the transceiver and rate at which the vehicle is approaching the transceiver correlates with stored data that identifies a potentially dangerous combination of range and rate.

4. A traffic roadway intersection comprising:
-
intersecting roads; a self-contained warning system proximate the intersection for alerting a driver of an approaching vehicle of a need to brake the vehicle, the warning system comprising, i) a transceiver for radiating electromagnetic energy toward the approaching vehicle and receiving reflected energy from the vehicle, ii) a processor associated with the transceiver for processing data about the reflected energy in relation to data about the radiated energy to yield data disclosing both range of the approaching vehicle from the intersection and rate at which the vehicle is approaching the intersection, iii) the processor containing stored data that correlates various combinations of range and speed that distinguish between combinations of potentially dangerous range and speed and combinations that are not potentially dangerous, iv) the processor operating to process the data disclosing range of the approaching vehicle from the intersection and rate at which the vehicle is approaching the intersection in relation to the stored data, and v) a signaling device that is activated to signal the approaching vehicle when the processor determines that the data disclosing range of the approaching vehicle from the intersection and rate at which the vehicle is approaching the intersection correlates with stored data that identifies a potentially dangerous combination of range and rate. - View Dependent Claims (5, 6, 7)

8. A traffic roadway comprising:
-
a road on which vehicles travel; a self-contained warning system proximate the road for alerting a driver of a vehicle approaching the warning system of a need to brake the vehicle, the warning system comprising, i) a transceiver for radiating electromagnetic energy toward the approaching vehicle and receiving reflected energy from the vehicle, ii) a processor associated with the transceiver for processing data about the reflected energy in relation to data about the radiated energy to yield data disclosing both range of the approaching vehicle from the warning system and rate at which the vehicle is approaching the warning system, iii) the processor containing stored data that correlates various combinations of range and speed that distinguish between combinations of potentially dangerous range and speed and combinations that are not potentially dangerous, iv) the processor operating to process the data disclosing range of the approaching vehicle from the warning system and rate at which the vehicle is approaching the warning system in relation to the stored data, and v) a signaling device that is activated to signal the approaching vehicle when the processor determines that the data disclosing range of the approaching vehicle from the warning system and rate at which the vehicle is approaching the warning system correlates with stored data that identifies a potentially dangerous combination of range and rate. - View Dependent Claims (9, 10, 11)
