The traffic accident videos are divided into two categories, one is the freeway, and another one is surface street, and the degree of danger is divided into three types: high, medium, and low according to the drivers' reactional behaviors.
We mainly judge the degree of danger based on the perspective of the vehicle that recorded the accident.
The sound and the driver's reaction are the important risk assessment policies for a car accident prediction. The greater the reaction in the car, the easier it is to be classified as high risk. Once the sound in the video does not exist, we will judge the risk factor visually only.
Videos without sound will be judged from the accident site's distance and the speed at which the vehicle slows down after the accident is recorded. The closer you are, the faster the speed is, the easier it is to be classified as high risk; otherwise, it is classified as low risk.
