Abstract
— Our paper deals with automatic detection of red light
traffic signals or vehicle speed limit signs on roads by using RFID
technology to control an automobile. In the present scenario traffic
violations are increasing rapidly. It gives rise to major problems
which are beyond human control directly and therefore there is a need
for automation. An RFID reader present in the vehicle senses the
active RFID tag(which is linked with a red traffic light to turn it on or
off) or senses the vehicle speed limit on the tag as a reference speed
input(attached to the speed limit signboard).This is given to the
electronic control unit. Meanwhile the vehicle speed sensor present in
the wheel gives the actual speed of the vehicle on road. The output of
this ECU unit is given to the proposed braking system present in the
automobiles. We here suggest two braking systems in this paper
INTRODUCTION
IVEN below are the statistics of the road accidents
especially in India. The seriousness of running a red light
traffic signal and speed violation on roads can be seen
from the statistics given below.
Working:
During a red light traffic situation, the tags are detected by
the reader present in the vehicles. Reader produces an output
which is again an input to the electronic control unit. On basis
of an algorithm, the ECU analyses and produces an output
signal. This output is given to the electro proportional pilot.
Meanwhile this same output turns on the dc motor, which
pumps the braking fluid from the container upwards. The
limiter present will set a constant pressure flow and send it to
the electro proportional valve. On the basis of the output
provided by the ECU, the valve sends only the necessary
pressure to be applied on wheels. Say if the output of the ECU
is some analog value this analog value is converted to its
equivalent pressure value and this pressure is sent to the
switching valve. Now since the high pressure will be from the
motor side, the ball will close the original braking system.
This pressure is applied on the wheels so that the vehicle stops
under the red light condition without violating
