Pothole and hump detection cum warning system for vehicles

Abstract

Accidents due to pothole and hump are a cause of majority of road accidents in India and in many other
developing countries. This happens due to lack of proper maintenance of roads. The problems due to
potholes increase to a greater extent especially in bad weathers and at night. On an average, a minimum
of seven to ten people die or encounter a fatal accident due to potholes on the roads. It is a necessity for
people to have well maintained roads to be able to avail a safe travel. Poorly maintained roads also have
an impact on the economy of the country. This paper discusses a method to detect potholes in order to
slow down the high rate of accidents that is amplifying every year. The method comprises of a detection
and a warning system involving a novel LiDAR sensor that detects the potholes or humps. On the basis of
the detected value of distance, it is identified to be a pothole or a hump. Upon the detection of the
mentioned irregularities on the road, the simultaneous multi warning system alerts the driver which
includes a seven segment LCD display, a red LED, an electronic buzzer and a vibration motor. This
system will alert the driver so that he can take necessary measures and prevent accidents due to humps or
potholes ahead of the vehicle on the road.
