Traffic monitoring and accident detection at intersections

The number of deaths and injuries from traffic accidents has been rapidly increasing. Most of those accidents occur at and nearby intersections. In order to analyze those accident events, we set up a video camera and recorded those traffic activities all day. In this paper, we describe this traffic monitoring system, the method for tracking vehicles, and the method for detecting accidents by using the hidden Markov model. Finally, we demonstrate our success by presenting the experimental results achieved by applying this method to video sequences obtained by the monitoring system.
