In low-or middle-income countries, road traffic safety becomes challenging because of the increasing number of vehicles, limited road infrastructure, and inability to capture a variety of traffic violations. Traffic Management and Information Control Centres (TMICCs) collect and analyse traffic data to improve road traffic safety. State-of-the-art technologies, such as the Internet of drones and computer vision, could help to automatically extract traffic data and provide a hands-free solution for road traffic monitoring. Hence, we propose a “UAV-based Urban Traffic Monitoring (U-UTM)” system to automatically extract traffic violations based on the movement of vehicles and traffic flow parameters, which helps to improve road traffic safety. Along with proposing a framework, this paper implemented three U-UTM operations - estimating Ground Sample Distance (GSD), detecting lanes using vehicles' tracks, and post-processing to reduce broken tracks. This paper derived GSD mapping from empirical data, improved it by 25.09% over theoretical GSD mapping, accurately detected lanes/zones, and reduced broken tracks of vehicles by 48.19 %.
