Road Accident Alert System

How the Core System Works

Unlike automated crash detection systems (like those on iPhones or Pixel devices) that use on-board sensors to guess if a crash occurred, NekInsan relies heavily on a human-activated community model to prevent false alarms and ensure a rapid response.

1. The Reactive Safety QR System

• Placement: Users purchase vehicle-specific "Jeevan Raksha" (Life Safety) QR stickers and place them on highly visible areas like a car's windshield or a motorcycle helmet.

• Bystander Intervention: If a driver is incapacitated in an accident, any passerby or police officer can scan the QR code using a standard smartphone camera or QR reader.

• Instant High-Priority Siren: Once scanned, the system instantly triggers a loud siren on the pre-registered emergency contacts' phones. This siren is designed to bypass silent or "Do Not Disturb" modes and lock screens.

• Scene Documentation & Location: The bystander is prompted to take a photo or a 1-minute video of the accident scene, which is immediately shared with the family alongside the precise GPS coordinates of the crash.

• Call Masking: To maintain privacy, the bystander and the family can speak to each other via a virtual, masked phone number without revealing their actual personal numbers.

2. Proactive "Accident Prevention" Features

While the QR sticker handles the aftermath of a crash, the NekInsan App works in the background during transit to prevent accidents:

• Over-Speed & Rash Driving Alerts: Utilizing the smartphone's built-in GPS and accelerometer, the app tracks driving dynamics. If dangerous behavior is detected, family members are notified.

• Audio Safety Messages: If family members see an over-speeding alert, they can send a quick pre-recorded voice message that automatically plays out loud on the driver's phone to remind them to slow down.

• Black-Spot Warnings: The app gives real-time voice alerts to drivers as they approach known accident-prone zones or highway "black spots."

3. In-App SOS Mode

If the driver is conscious but trapped or in immediate danger, they can manually hit the app’s internal SOS button. This triggers the family siren, records a 1-minute ambient audio clip of the surroundings, and continuously streams their live location.

Technical Setup & Best Practices

To ensure the ecosystem works reliably during a crisis, users typically follow these steps:

• Critical Device Permissions: For the app to bypass device restrictions, users must allow "Display over other apps," disable battery optimization (so the app doesn't go to sleep while driving), and set location permissions to "Always Allow."

• Emergency Contacts: Users must link 3 to 5 trusted mobile numbers inside the app profile.

• Sticker Registration: Physical QR stickers must be registered by scanning them within the app and binding them to the vehicle's registration number plate.

Additional Everyday Uses

Beyond accident emergencies, the NekInsan ecosystem serves everyday functions:

• Wrong Parking Alert: If a vehicle blocks an exit, anyone can scan the QR code to notify the owner to move it without seeing the owner's phone number.

• Saman Suraksha (Lost & Found): They offer smaller tags for luggage, keys, laptops, and pets, allowing people to anonymously contact the owner if found.
