Abstract: In many developing countries the maintenance of roads are the major problem. A country’s economy also determined by the safe roads and the road conditions of the country. India, as a second populous country in the world, also a fast growing country. There are huge network of roads. Even from Kashmir to Kanyakumari broad roads are the dominant means of transportation in India. This work discusses merits and demerits of previous pothole detection methods that have been developed and proposes a cost effective solution to identify potholes and humps on roads and provide timely alerts to drivers to avoid accidents or vehicle damages. Ultrasonic sensors are used to identify potholes and humps. They also measure their depth and height respectively. The proposed system captures the geographical location coordinates of potholes and humps using GPS receiver. The sensed-data includes pothole depth, height of hump and geographic location, which is stored in the database(cloud). This serves as a valuable source of information to the Government authorities and to vehicle drivers. An android application is used to alert drivers so that precautionary measures can be taken to evade accidents. Alerts are given in the form of a flash messages with an audio beep and long beep alarm to the drivers. The Arduino UNO is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Ultrasonic sensors work by emitting sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating distance based on the time required. This is similar to how radar measures the time it takes a radio wave to return after hitting an object.
