Embodiment
[0079] In view of the traffic flow division method described above in the present application, an embodiment statement is made to verify the calculation method of the present application.
[0080] First embodiment based on the survey road section selection principle, selection Figure 6 The two survey sections shown, while selecting 6:50-8:10 a.m. on weekdays in sunny weather as the survey time period, the nature of the survey section is shown in Table 1,
[0081] Table 1 Investigates the road segment properties
[0082]
[0083]
[0084] Then the data is pre-processed, and the video information obtained by the camera is played back to record the traffic information such as the speed and front distance of the vehicle, and the data of the front distance of the vehicle is 0, the research range of the front distance frequency is determined, and the traffic data of the speeding vehicle is excluded;
[0085] The statistical interval is then determined, by appending Figure 2 It can b...
