Embodiment 1
[0050] This embodiment provides a system for quickly inquiring travel time using the Internet, such as figure 1 As shown, it includes a central data processing unit 1, several video tracking units 2 and a network query unit 3.
[0051] The video tracking unit 2 is arranged on at least one side of the road along the direction of travel of the vehicle, and each lane in the tracking range of each of the video tracking units 2 includes two signals indicating that the vehicle enters the tracking range and leaves the tracking range. Reference point or reference line, the video tracking unit 2 continuously tracks each vehicle entering its video tracking range, two adjacent video tracking ranges have an overlapping area, and each lane in the overlapping area contains a reference point Or a reference line; for a road with two or more lanes, the video tracking unit 2 judges whether there is a driving vehicle on each lane within the video tracking range.
[0052] Each of the video track...
Embodiment 2
[0069] The present embodiment provides a kind of method utilizing Internet to inquire travel time fast, comprises the steps:
[0070] S1: Multiple video tracking ranges are set on the road. Each lane in each video tracking range includes two reference points or reference lines indicating that the vehicle enters the tracking range and leaves the tracking range. Two adjacent video tracking ranges overlap area, each lane in the overlapping area contains a reference point or reference line;
[0071] S2: Each video tracking range is preset with its corresponding travel time T L , at the initial time T L = T x , where T x The minimum travel time is the time required for the vehicle to quickly drive through the video tracking range at the speed specified by the speed limit;
[0072] S3: For each video tracking range, continuously track each vehicle entering it, and obtain the first reference point or reference line and the second reference point or reference line of each vehicle wi...
