An incident detection system is proposed based on three incident features:
traffic flow, vehicle angle and vehicle acceleration. The first step after image sequences
acquisition from the video image of CCD camera is vehicle detection, and then
the incident features such as direction of the moving vehicles, traffic flow and the
acceleration are extracted in order to achieve the detection results. This process gives
the best result by total 97.8% of correct rate and 1.02% of false alarm rate within 30 s.
The result shows that this method has a good effect.
