Abstract:

Traffic collisions remain a major cause of deaths all over the world. Many fatalities occur because of delays in emergency response instead of the crash itself. Our study presents a budget-friendly accident detection and alert system based on an Arduino platform, which combines GSM and GPS modules. Unlike traditional models, this system uses a jerk-based vector magnitude algorithm to analyse quick changes in acceleration from a G-sensor. This approach helps distinguish between real collisions and minor issues like potholes or sudden braking. When a crash is confirmed, the system automatically gets the vehicle’s location through a SIM808BL module and sends the coordinates via SMS to registered emergency contacts. It also includes a manual override button to reduce false alerts. The system is designed to work without internet access, making it useful in remote areas. Experimental tests showed that the prototype detected 90% of simulated collisions and filtered out 90% of harmless disturbances. It had an average notification delay of six seconds. Overall, this design offers a simple and affordable way to speed up emergency assistance and may decrease death rates which occur due to accidents.
