Abstract

Abstract: Traffic accidents negatively affect thelives of human beings. Accidents may result in deaths, severe injuries, andloss of income to the impacted families. Accident detection and prevention is akeystone in improving road safety. In this paper, a system for detectingvehicle collision and rollover is presented. The proposed system includes threekey phases. Data acquisition where accelerometer and gyroscope, integrated intoMPU-6050 motion sensor are used to acquire 3-axis acceleration forces androtation angles respectively. The complementary filter is used to enable theuse of the gyroscope data on the short term because it is very precise and notsusceptible to external forces. On the long term, the accelerometer data isused because it does not drift. An algorithm for acquiring data using sensors,filtering and analysing data, detecting collision and rollover is developed.Experiments are conducted to test the proposed system. Experiments showpromising results.
