Traffic congestion analysis: A new Perspective

In this paper, a new perspective of congestion is presented to promote the development of traffic video analysis. Our main contributions are threefold: a) An unified and quantifiable definition of congestion is proposed to describe the traffic state in video. b) Based on the definition, a congestion dataset which contains multiple traffic scenes is constructed as a platform for the research community. At the same time, a precise labeling method is introduced to get the ground truth of congestion level accurately. c) An algorithm based on Inverse Perspective Mapping (IPM) and pairwise regression is proposed to analyze traffic videos and serves as a baseline. We further compare the proposed method with two deep learning methods. Intensive experiments justify the effectiveness of the proposed method.
