Sensor-based espial of potholes and humps on roads with instant notification alert using IoT

Potholes are hollow detrimental structural impairment in areas of road surface that have splintered, eroded, and eventually formed a depression of varying depths depending upon the extent of the damage. It can potentially impair the quality of road infrastructure and road efficiency. It makes roads bumpy and causes misalignment of wheels and tire damage. It is the main reason for road anomalies and casualties. Manual detection of potholes in roads can be tedious, time-consuming, inaccurate, and inefficient. Hence, there is a need for efficient automated pothole detection system. Although several pothole detection techniques are being introduced, and efficient advancements are expected in the near future, there persists a major challenge in terms of cost-effective implementation. In this paper, various pothole detection techniques implementing different technologies are compared of their strengths and shortcomings and summarized. To implement a cost-effective pothole detection system, a sensor-based pothole detection system using ultrasonic sensors has been proposed. When the sensor detects the presence of potholes, it notifies the driver by sending an alert via mobile application which has to be integrated with detection system and the data can be stored in a server to intimate the government about road repairs and maintenance. The proposed method is simple and less expensive when compared to other methods. It can be widely used in a variety of automobiles. The possible future development plans that can be integrated with this system are also illustrated in this paper.
