This document describes a vehicle accident prevention system that uses various sensors and components to prevent accidents by enforcing traffic rules. It monitors vehicles using a USB camera and automatically issues penalties if rules are violated, such as blocking lanes, running red lights, or speeding. It also prevents drunk driving by not allowing the car to start if the driver is intoxicated. The system is intended to improve traffic safety and discipline on the road. It uses components like a NodeMCU microcontroller, alcohol sensor, motor driver, GSM module and camera to detect violations and send alerts. The researchers conclude that this kind of system can help reduce accidents by enforcing rules and increasing road safety.
