In this fast generation, the human has
no time for anything. He is completely busy with his personal work and totally
devoted himself to the so called computers or laptops. A common man usually
prefers his own transport to go to office or work. On the roads, they sometimes
go against the traffic rules, jump the traffic signals etc. He mainly does all
this kind of odd activities to reach the office on time. Thus, it takes a good
amount of time for us to realize that we need to help others mainly the
patients in the ambulance. We merely bother about them and do not give space to
the ambulances so that they reach the hospitals soon and will be saved out of
danger. Thus, this project is designed to clear the traffic and provide a way
to the ambulance so that the patient can be saved upto the maximum extent.
The project uses Zeegbee technology to
implement this application. The ambulance will be fixed with the Zeegbee
transmitter and the Zeegbee receiver will be fixed at the traffic signals. This
transmitter transmits a unique code continuously into air. When the ambulance
is near to the traffic signals, the unique code, transmitted by the transmitter
from the ambulance, will be received by the Zeegbee receiver at the traffic
signals.
The controlling unit, after receiving
the data from the Zeegbee receiver operates the traffic signals so as to allow
the ambulance to move on without stopping it i.e., the green signal will be
given for a long time so that the ambulance cannot be caught in the traffic.
This green light will be given until the output of the Zeegbee receiver
changes. The output changes when the Zeegbee receiver does not receive any
input from the transmitter. After the ambulance has passed away, the traffic
signals will be operated as usual.
