Embodiment
[0079] Now, aiming at the traffic flow division method described above in this application, an example statement is made to verify the calculation method of this application.
[0080] First of all, the embodiment is based on the principle of selecting road sections for investigation, and selects Figure 6 For the two survey road sections shown, at the same time, we choose a sunny working day from 6:50 to 8:10 am as the survey time period. The nature of the survey road sections is shown in Table 1.
[0081] Table 1 Investigating road segment attributes
[0082]
[0083]
[0084] Then the data is preprocessed, and the video information acquired by the camera is played back to record traffic information such as vehicle speed and headway in the traffic flow, and the data with a headway of 0 is eliminated to determine the research interval of the headway frequency and eliminate the speeding vehicle. traffic data;
[0085] Then determine the statistical time interval, by the...
