: We do the establishment of the ground coordinate system by OPENCV software to obtain the actual coordinates, which is converted to vehicle coordinates in every pixel to get the parameters such as location and speed. MFC platform software which we exploited can directly output vehicle trajectory, speed and traffic conflict corresponding to the TTC time. There are different levels of colour marked in the map of the conflict distribution points. We use the cumulative frequency curve method to deal with the collected conflict samples, getting the TTC value which is used to define serious conflict and non-serious conflict. At the same time, we joined the car-following conflict, enriching our research content.
