Abstract: Almost every today’s 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. Improving the condition of road has become a necessity now days. Android Smartphone’s are user-friendly way to solve the problem. Latest smart phone consist of useful sensors like accelerometer, Magnetometer and GPS (Global Positioning System). Any user can make use of these sensors to find bad road condition which are encountered every day while driving. The paper is describing a mobile sensing system for road irregularity detection using Android OS based smart-phones.
