Traffic light prediction system
First Claim
1. A Traffic Light Prediction System that controls speed of vehicles to save fuel and promote safety by avoiding red lights or by decelerating before a red light comprisingat least a broadcast unit at a traffic light for broadcasting information about said traffic light,communicators, positioned at varying distances along the street extending out from said traffic light, for receiving said information and for passing message by wireless to vehicles close to each of said communicators, wherein said message comprises distance of the communicator to the traffic light, color periods and color phase of said traffic light, speed limit, speed of moving section, and ID of said traffic lightreceivers and microprocessors installed on vehicles for receiving and processing said message and said information and communicating with cruise controls of vehicle,at least a distance sensor installed in front of a vehicle to sense distance from another vehicle in front.

Abstract
A traffic system that helps a driver to save fuel by avoiding red light or by minimized fuel supply before stopping a red light. It predicts the colors of a traffic light and automatically control the speed of the vehicle. The system comprising three kinds of moving sections representing three future colors: green, yellow, and red. The moving sections are moving towards the traffic light. There is a microprocessor in each vehicle to receive messages from the traffic light in front and to calculate an optimal speed to the cruise control in the vehicle.
