Motorist Warning System on Road Bends in Hilly Regions for Safer Riding 2020-28-0480

Safety is a major concern addressed in various industries and most specifically in transportation industries. Road accidents are undoubtedly more frequent and are responsible for many permanent disabilities deaths worldwide. Many works have been done to improve the safety of different vehicles as the number of accidents is increasing. The main objective of this work is to further improve road safety by providing instantaneous warnings to drivers about hazards in their intended path in hilly region. This further it aims to provide a pleasant and peaceful hill travel and to avoid any possibility of accidents in hill curves. The roads in these hilly regions are always filled with many hectic and endless curves. These curves are classified into Hair-Pin Curves, Salient Curves and Re-entrant Curves. These curves offers partial or no visibility about the incoming traffic for the drivers. In this approach two ultrasonic sensors are used to obtain the velocity and the distance of the object placed in the curves. The signals from the two sensors are obtained, compared and the probability of the vehicles reaching the curves is predicted using a simple algorithm with the help of Arduino UNO module. Then the warning signals are provided to the lamps and thus the drivers can be alerted by this approach the accidents can be avoided effectively.
