Study on Freeway Automatic Incident Detection System and Algorithm

Traffic incident is a main factor to cause traffic delay, so detecting incident and taking measures play a key role on traffic management and control. The composing and the operation flow of the system are introduced firstly. Based on the introduction, the sensors used for data collection are comparatively analyzed. After discussing the performances of various sensors, some principles for selecting sensors are outlined. The performance of a detection algorithm is compounded, and merits and demerits of various detection algorithms are pointed out through comparatively studying. In the end, future research work is prospected.
