Accident Detection & Alert Android App

Abstract:

The “Accident Detection & Alert Android App” is designed to automatically detect road accidents and promptly alert emergency contacts and services. Using sensors, GPS, and real-time data processing, the app aims to enhance safety by providing immediate assistance in case of an accident. Key features include accident detection through accelerometer and gyroscope data, real-time location sharing, automated alerts to emergency contacts, and integration with emergency services for swift response.

Existing System:

Traditional accident detection and alert systems often rely on manual reporting by the accident victims or bystanders. This approach can result in delays in emergency response, especially in critical situations where immediate assistance is crucial. Existing solutions may lack integration with real-time location tracking and automated alert systems, leading to inefficiencies in emergency response and higher risks for accident victims.

Proposed System:

The “Accident Detection & Alert Android App” proposes a solution that automates the accident detection process and facilitates rapid emergency response. By leveraging smartphone sensors, GPS, and real-time communication, the app aims to detect accidents accurately and trigger alerts to predefined emergency contacts and services. The system is designed to improve response times, enhance safety, and provide users with a reliable tool for handling accident scenarios.
