Abstract: Reliability of numerous smart traffic applications are highly dependent on the accuracy of underlying road user tracker. Demand on scalability and privacy preservation pushes vision-based smart traffic applications to sense and process images on edge devices and transmit only concise information to decision/fusion nodes. One of the requirements for deploying a vision algorithm on edge devices is its ability to process captured images in real time. To meet these needs, we propose a real-time road user tracker which outperforms state-of-the-art trackers. Our approach utilizes double thresholding on detector responses to suppress initialization of false positive trajectories while assuring corresponding detector responses required for updating trajectories are not wrongly discarded. Furthermore, our proposed Bayes filter reduces fragmentation and merging of trajectories which highly effect the performance of subsequent smart traffic applications. The performance of our tracker is evalua ted on the real life traffic data in turning movement counting (TMC) application and it achieves a high precision of 96% and recall of 95% while state-of-the-art tracker in comparison achieves 92% on precision and 87% on recall.
