ESTIMATION OF ROAD ROUGHNESS CONDITION BY USING SENSORS IN SMARTPHONES

Today’s every smartphone is integrated with many useful sensors. The sensors are originally designed to make the smartphones user interface and applications more convenient and appealing. These sensors are potentially useful for many other applications in different fields. The smartphone sensors like accelerometer and orientation are used to estimate road roughness condition. These sensors are used to collect vibration data. Using these sensors data about road is collected. The smartphones are placed at more realistic locations and under realistic manner inside a moving vehicle to collect the data which is useful to evaluate its relationship with the actual road roughness. In this paper, road roughness (Quality) and Ghats complexity analysis using smartphone proposes to utilize the GPS system of phone and different sensors like accelerometer, magnetometer, etc. of phone, so we can analyze the road and can upload this information of that road on central server so every application user can use this information during traveling.
