Intelligent Traffic Alerting and Control System
First Claim
1. A traffic alerting and control system comprisinga transmitter module associated with a traffic alerting device to generate messages containing information about the traffic alerting device and transmitting the messages in direction of vehicles approaching the traffic alerting device;
- anda receiver module associated with a vehicle to receive messages from the transmitter module, extract the information about the traffic alerting device, determine location, direction and speed of the vehicle, determine if the vehicle is on path of the traffic alerting device, and determine if alerts associated with the traffic alerting device should be provided to the vehicle.

Abstract
A system to alert drivers approaching a traffic intersection controlled by a traffic signal light. The system may alert about an impending change in the state of the signal from green to red, to allow them to plan ahead and stop the vehicle safely. The system can be used to slow down and stop an autonomous vehicle (driven by a robot) safely at an intersection. It can also be used to implement “active” or “intelligent” stop signs that warn the driver if the vehicle does not slow down when it has crossed the safe stopping distance at an intersection. It may be used as a virtual hazard warning system to warn motorists of temporary hazards or bottlenecks on the roadway; or as an aid for visually impaired drivers (drivers with color blindness, partially or fully blind drivers).

16. A traffic alerting and control system comprising
a transmitter module associated with a traffic alerting device to generate messages containing information about the traffic alerting device and transmitting the messages in direction of vehicles approaching the traffic alerting device; - and
a receiver module associated with a vehicle to receive messages from the transmitter module, extract the information about the traffic alerting device, determine location, direction and speed of the vehicle, determine if the vehicle is on path of the traffic alerting device, and if the vehicle is on the path of the traffic alerting device to determine one or more alert zones for the traffic alerting device based on location and speed of the vehicle; determine when the vehicle is in any of the one or more alert zones; and initiate an appropriate alert for the one or more alert zones.
