PROJECT NO STOP LIGHTS
By: - PRATYUSH JHA
INTRODUCTION
This is a new technology
which works on the basic principle i.e. speed = distance/time. Now if we get
the two values as written we can calculate the speed of a vehicle and if the
details are accurate then there is absolutely no possibility for errors. Now if
you think practically you can understand that how this works as well as how
this could be helpful in getting you relief from red lights, traffic jams. This
simple formula can help you in getting home from your office earlier, and even
could help you in saving the so called fuel.
Now the single question
which can arise in your wind would be how?
So let me tell you that you
do need not to spend a huge capital to do that you can just use your existing
basic car accessories and in fact you own GPS receiver. Confused! As we all
know that a GPS receiver tells us the exact location of our vehicle on any part
of the globe. This is done by the revolving 31 satellites in the space called
GPS satellites controlled by U.S MILITARY from the home of GPS SCHRIEVER AIR
FORCE BASE. And at any point on globe there are at least 3 of the satellites
that cover the receiver now with the help of triangulation a mathematical
technique we easily get the position where we are in terms of degrees of
latitude and longitude and it can also be projected on a map. A GPS receiver
can tell you in which direction you are heading, what is your speed and the
estimated time when you will reach your provided destination. Using these we
can make a system which will help you in getting rid of the red lights. So for
you all the lights will be green always hence I have given the name of this
project as no stop lights.
UNDERSTANDING THE GPS
The GPS
stands for the Global Positioning System, as suggested by the name it tells you
the location anywhere on the globe. Now the common question is HOW? The answer
is that when we stand under the sky there are at least three GPS satellites on
the top of our head there are 24 satellites that are necessary for this course
of action. So the with the help of these satellites your GPS receiver tells you
your exact location on the globe.
Wherever you stand on the earth there are at least
3 of the satellites on the top of your head covering your position current
position.
All the GPS satellites
transmit a 50 Hz signal consisting of date, accurate time when the signal is
being transmitted, and the position of the satellites by this data your GPS
receiver by simple mathematical calculations calculates your position.
OVERVIEW
The
requirement is of a minimal modification in the existing system. Let us see how
this will work now in the present conditions if someone tells you to run on a
speed and you will get no red lights in front of you that will work as a good
solution. But how to get that estimated speed? To acquire it you will need the
accurate distance between you and the red light pole and the estimated time
till when the light will be green. So the distance can be acquired from your
GPS. And the time will be sent by the red light transmitter through RF signals.
The modified GPS receiver receives the distance from the GPS unit and time from
the red light and will calculate the estimated speed on which if you run your
vehicle will get green light in front of you. Now by synchronizing the whole
system and giving a dedicated line for the vehicles equipped with this
technology will help commuters to travel on a constant speed and cross all the
red lights without any hassle. Isn’t that wonderful now there is no need to
wait for the red lights to be green no more traffic jams and most important
thing of all the fuel will be saved by maintaining the speed of your vehicle.
As clearly seen in the figure there are
GPS satellites and a car equipped with GPS and wireless receiver and a red
light with the same GPS but with the transmitter.
