SPEED CHECKER TO DETECT RASH DRIVING ON
HIGHWAYS
ABSTRACT
The aim of this project is to develop a device to detect rash driving on highways and to
alert the traffic authorities in case of any speed violation. Accidents due to rash driving on
highways are on the rise and people are losing their lives because of others mistakes. In the
present system, to detect rash driving the police has to use a handheld radar gun and aim at the
vehicle to record its speed. If the speed of the vehicle exceeds the speed limit, nearest police
station is informed to stop the speeding vehicle. This is an ineffective process as after detecting
one has to inform the same and a lot of time is wasted.
The proposed system will check on rash driving by calculating the speed of a vehicle
using the time taken to travel between the two set points at a fixed distance. A set point consists
of a pair of sensors comprising of an IR transmitter and an IR receiver, each of which are
installed on either sides of the road. The speed limit is set by the police who uses the system
depending upon the traffic at the very location. The time taken by the vehicle to travel from one
set point to the other is calculated by a microcontroller program. Based on that time it then
calculates the speed and displays that on an LCD. Moreover if the vehicle crosses the speed
limit, a buzzer sounds alerting the police.
This concept can be extended in future by integrating a camera with the system which
could capture the image of the number plate of the vehicle to sends that to the traffic authorities.
