As one type of asphalt troubles, potholes are indispensable signs showing basic imperfections of the streets and identification of these potholes is one among the basic errands for determinative right techniques on road surfaced asphalt support and recovery. Be that as it may, physical location and assessing ways are cherished and tedious. The main cons of potholes are the escalating death rate and damage/bending in vehicle tires. Consequently, numerous endeavors are made for building up an innovation that may precisely watch and perceive potholes, which can add to the improvement in asphalt quality through past examination and quick activity. This paper compares different case studies such as image processing, clustering analysis, black box camera, laser technology, and Zigbee protocol for predicting the potholes accurately. This paper presents state of the art on well-known pothole identification techniques that discusses various methodologies and identifies optimum solutions for real-time implementation under worst environment and operating conditions thus ensuring human safety.
