Accident Prevention and Detection System on Curved Road using Arduino

Introduction

Accidents on curved roads are common due to blind spots, over-speeding, and poor visibility. The Accident Prevention and Detection System using Arduino is designed to alert drivers and detect collisions on such roads. This IoT-based safety system integrates ultrasonic sensors, IR sensors, and RF communication to ensure smooth and accident-free navigation on curved roads.

Components Used

• Arduino Uno – Main microcontroller to process sensor data.
• Ultrasonic Sensors – Detects nearby vehicles and obstacles.
• IR Sensors – Detects vehicle movement at critical points.
• RF Transmitters & Receivers – Enables communication between both ends of the curved road.
• LED Display / Buzzer – Provides real-time alerts to approaching vehicles.
• GSM Module (SIM800L/SIM900A) – Sends alerts in case of an accident.
• GPS Module (NEO-6M) – Tracks vehicle location after an accident.

How It Works

1. Vehicle Detection – Ultrasonic and IR sensors detect vehicles approaching from both ends of the curve.
2. Real-Time Alerts – RF modules communicate and warn drivers about oncoming vehicles using LED indicators and buzzers.
3. Accident Detection – If a vehicle collides, impact sensors trigger an emergency response.
4. Automatic Emergency Alert – The GSM module sends an SMS with GPS coordinates to authorities and nearby responders.
5. Data Logging (Optional) – The system can log accident details for analysis and safety improvements.

Key Features

✔️ Prevention Mechanism – Alerts drivers about oncoming traffic to prevent accidents.
✔️ Real-Time Vehicle Detection – Uses ultrasonic & IR sensors for immediate detection.
✔️ Automatic Accident Alerts – Sends SMS alerts with GPS location for quick emergency response.
✔️ RF Communication – Ensures reliable vehicle-to-vehicle warning signals.
✔️ Low Cost & Energy Efficient – Uses minimal power and is easy to deploy.

Applications

✅ Hilly & Curved Roads – Enhances safety on dangerous turns.
✅ Highways & Expressways – Reduces collision risks at high speeds.
✅ Smart Traffic Management – Integrates with smart city road safety solutions.
✅ Foggy & Low Visibility Areas – Helps in areas prone to weather-related accidents.

This Accident Prevention and Detection System improves road safety by offering real-time alerts and automatic emergency responses, making curved roads safer for drivers and pedestrians. 🚦🚗⚠️
