Comprehensive Systems Review for Accident Detection, Prevention, and Real-Time Alerting Mechanisms

The growth of technology and infrastructure at a rapid pace has made our lives easier. The increased frequency of road accidents and possible traffic dangers brought about by newer technologies has resulted in a significant loss of life and property due to inadequate emergency facilities and preventive measures. The greatest hazard to human life is traffic accidents. High speeds combined with intoxication are the main causes of many accidents. Vehicle safety and accident prevention and detection systems are important because they reduce the number of accidents and the time it takes for an accident to be recognized, allowing rescue personnel to attend to injured victims more quickly. This article presents the MCU-designed Vehicle Tracking and Accident Detection system along with several accident avoidance strategies.A prototype of an accident prevention & detection system using a vibration sensor as the detector and an ultrasonic sensor, or IR sensor, is to detect a signal in case of a near collision or a distance between two vehicles to prevent an accident. Even after this, if an accident occurs, they send a signal to the connected microcontroller via the vibration sensor. When the signal is received, the controller activates the relay, causing the airbag to deploy and the brakes to automatically lock. Meanwhile, a message is sent to the nearest help center, so ambulance service and other aid can come in the quickest time feasible.A black box gathers driving information before, during, and after a crash about the vehicle in which it is installed. The data collected by the black box includes speed, braking, acceleration, steering, and airbag deployment. The help can be provided in areas like vehicle safety, collision victim care, insurance corporations, vehicle crash investigations, and improving road conditions through the automotive black box system, which can reduce death rates to a significant level. The main aim of this paper is to include the overview and basics of certain techniques utilized to prevent, detect accidents, and alert the nearby help centers for the fastest aid in case of an accident.
