Abstract

A traffic system that helps a driver to save gasoline by avoiding red light or by decelerating before a red light. It predicts the colors of a traffic light and informs about the future traffic light colors that will happen to a driver. 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 driver advisor in a vehicle displaying the positions of the vehicle, the traffic light, and the moving sections.

Claims

1. A Traffic Light Prediction System that helps a driver to save gasoline 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 future periods of the 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, comprising:

a) One driver advisor unit for each vehicle, said driver advisor gives video and audio advise to the driver;

b) At least one communicator, said communicators send messages to said driver advisors about the traffic light cycling information, distance of said communicator to the traffic light, the traffic light identification number, speed of said moving sections, and speed limit for the street;

c) At least one broadcast unit, said broadcast unit broadcasts the traffic

d) light cycling information and the traffic light identification number;

2. The Traffic Light Predication System of claim 1, wherein the messages that each of said communicators sends to said driver advisor units comprise:

a) the traffic light cycling information comprising;

1. The period of green light;

2. The period of yellow light;

3. The period of red light;

4. The phase of the traffic light cycle;

b) the distance from said each of said communicators to the traffic light;

c) the identification number of the traffic light to which said communicators are guiding to;

d) the speed of said moving sections;

e) the speed limit;

3. The Traffic Light Predication System of claim 1, wherein the messages that said broadcast unit broadcasts comprise:

a) the traffic light cycling information comprising;

1. the period of green light;

2. the period of yellow light;

3. the period of red light;

4. the phase of the traffic light cycle;

b) The identification number of the traffic light;

4. The Traffic Light Predication System of claim 1, wherein said driver advisor unit comprises:

a) at least one sensor or antenna;

b) at least one microprocessor;

c) at least one video device, displaying the positions of the vehicle, the traffic light, and said moving sections;

d) at least one audio device, giving advise of how to change the vehicle speed;

5. The Traffic Light Predication System of claim 1, wherein the carriers of messages sent by said communicators comprise:

a) infrared rate;

b) radio frequency;

c) microwave;

d) laser;
