Road accidents are the major cause for the loss of life's that held in our day to day. In 2018 road accidents is about 1,51,589.In 2021 road accidents is about 1,31,389.The main cause for road accidents is not wearing the helmet and consumption of alcohol. Our project is to control road accidents using smart bike and helmet. Our project consists of two parts: helmet part and detection part. In Helmet part we use IR sensor and Alcohol sensor another one is detection part. In detection we use LDR sensor, the ultrasonic sensor, speed sensor, display. It used to control road accidents by detecting the obstacles in distance using ultrasonic sensor. And the sound waves from ultrasonic sensors calculates the distance of obstacles and gives warning to the rider by using a display and using the WiFi technology to control the helmet and bike.
