Embodiment 1
[0047] This embodiment provides a system for querying and receiving travel time using a mobile terminal, such as figure 1 As shown, it includes a data processing unit 1, several video tracking units 2 and a mobile terminal 3. The video tracking units 2 are arranged on at least one side of the road along the driving direction of the vehicle, and each of the video tracking units 2 has definite position information, which may be latitude and longitude coordinate information. Each lane in the tracking range of each described video tracking unit 2 includes two reference points or reference lines representing that the vehicle enters the tracking range and leaves the tracking range, and the video tracking unit 2 enters its video tracking range Each vehicle in the continuous tracking, two adjacent video tracking ranges have an overlapping area, and each lane in the overlapping area contains a reference point or a reference line; the video tracking unit 2 acquires the The travel time ...
Embodiment 2
[0070] This embodiment provides a method for using a mobile terminal to query and receive travel time. This embodiment includes two parts, one is how to accurately obtain the travel time accurate to the second under the current road traffic conditions; the other is how to accurately determine the travel time of the mobile terminal The current location and the travel time from the current location to the destination are issued to the terminal.
[0071] Such as image 3 shown, including the following steps:
[0072] S1: a plurality of video tracking units 2 are set on the road, and each lane in the video tracking range of each video tracking unit 2 includes two reference points or reference lines representing that the vehicle enters the tracking range and leaves the tracking range. Two adjacent video tracking ranges have an overlapping area, each lane in the overlapping area contains a reference point or a reference line, and travel time traveling between the two reference poin...
