Roads make a crucial contribution to economic development and growth and bring important social benefits. They are of vital importance in order to make a nation grow and develop. Roads open up more areas and stimulate economic and social development. For those reasons, road infrastructure is the most important of all public assets.  Poor state of roads in country has significantly increased the number of road accidents, leading to loss of lives and properties. This project aims at automatic identification of roadway obstacles like potholes and road bumps, literature study shows that much work is already done in past regarding automating this process like manually capturing photo of pothole or obstacle and reporting it to authorities by using ways like web application, telephone reporting, manual paper or by using android application.   In most of cases mentioned here user manual intervention is required and it is time consuming and costly at the same time. As roads are large in numbers, total length of roads is much high and new roads are constructed daily. Main problem is due to : Lack of a mechanism to trace and fix bad roads; There is no method to track potholes, so it takes long periods to fix them and then, the quality is also compromised. There is a need to develop application which will gather realtime data on poor road conditions, including potholes and road bumps which can help the organization in spotting potholes and fixing them before things get out of hand. Accelerometer and gyroscope of phone’s sensors can be used to detect when the user’s vehicle slows down and a bump is hit, while the GPS determines location. Data records or samples are taken at particular frequency. The algorithms in the application filter down to distinguish between potholes, speed bumps and stretches of bad road. The information is sent off into a larger data stream of information from users. When enough people hit a big bump in the same spot, the application recognizes it as a pothole.  Number of users need to be taken into consideration to get the better result and if number of users goes on increasing it will result in better result of course application developed will not be 100% accurate but with more data coming in, the application accuracy will goes on increasing.
