Traffic light prediction system
First Claim
1. A Traffic Light Prediction System that controls the speed of a vehicle to save fuel by avoiding red lights or by decelerating before a red light;
- said traffic light prediction system defines three kinds of moving sections, red sections, green sections, and yellow sections;
said moving sections are positioned at varying distances along the street extending out from the traffic light;
the length of said moving sections is related to periods of the future traffic light colors;
each kind of said moving sections represents at least one future color of the traffic light;
the movement of said moving sections is synchronized with the traffic light color periods so that the time each of said moving sections reaches the traffic light is the time that the traffic light changes the color to the color that said each moving section represents;
said traffic light prediction system includes a communicator and a broadcast unit to send out information about the periods of the traffic light colors, the phase of the periods, the speed of the moving sections, the distance of the communicator to the traffic light;
said traffic light prediction system comprises a microprocessor for calculation and sending the control message to cruise control, brake system, and a display unit;

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.
