Pedestrian traffic is an important subject of surveillance to ensure public safety and traffic management, which may benefit from intelligent and continuous analysis of Pedestrian traffic videos. State-of- the-art methods for intelligent pedestrian traffic surveillance have a number of limitations in automating and computing useful pedestrian traffic information from closed circuit television (CCTV) images. This work aims to automate and augment the traditional pedestrian traffic surveillance system by introducing four components in a novel integrated framework. A fast and efficient particle image velocimetry (PIV) technique is proposed to yield pedestrian velocities for timely management of pedestrian traffic. A machine learning-based regression model, boosted Ferns, is used to improve pedestrian count estimation: an essential metric for high-density pedestrian traffic analysis. A camera perspective model is proposed to improve the speed and position estimate of pedestrian traffic incorporating camera’s intrinsic and extrinsic parameters. All these functional improvements are integrated in a seamless framework to predict future pedestrian traffic distribution, which is a crucial piece of information for pedestrian traffic management. The proposed framework is computationally efficient, suitable for multiple camera feeds with high-density pedestrian traffic videos, and capable of rapidly analyzing and predicting flows of thousands of pedestrians. The proposed framework is one of the first steps towards fully integrated CCTV-based automated pedestrian traffic management system.
