Embodiment 1
[0034] figure 1 A flowchart of a method for merging road sections based on road conditions provided in Embodiment 1 of the present invention specifically includes the following steps:
[0035] S110. Acquire road condition characteristics of each road section within a unit period.
[0036] Wherein, the unit time period is a preset time period, exemplarily, the unit time period may be 1 minute or 5 minutes. The actual road is divided into road segments according to a preset method. The preset method includes the actual name of the road, the traffic rules of the road, and the angle at which the road bends. For example, a street named A in a city, motor vehicles Passable, the street has an inflection point, and the angle of the inflection point does not exceed 30°, the street can be identified as a road segment, if another street named B is prohibited from passing motor vehicles, then the street is not regarded as a road segment. section. The road condition characteristics of e...
Embodiment 2
[0043] The embodiment of the present invention also provides a road segment merging method based on road conditions. As a further description of the first embodiment, as figure 2 As shown, step S110 includes:
[0044] Step S111 , acquiring the travel speed and travel distance of each vehicle in the road section within a unit time period.
[0045] The driving speed of each vehicle in the road section is the average speed in the unit period, and the driving distance of each vehicle in the road section is the distance traveled by the vehicle on the road section in the unit period.
[0046] Step S112: Determine the vehicle whose travel distance of the vehicle is higher than the threshold distance as a valid vehicle.
[0047] When the distance traveled by the vehicle on the road section exceeds the preset distance, the vehicle is regarded as a valid vehicle, otherwise the relevant data of the vehicle is discarded. The data of vehicles with short driving distances are not obtaine...
Embodiment 3
[0075] A method for merging road segments based on road conditions provided in this embodiment, as a further description of the above-mentioned embodiment, as follows: Image 6 As shown in the figure, after the adjacent road sections are merged into a new road section according to the statistical results, it also includes:
[0076] Step S170: Determine a preset length interval matching each of the road segments.
[0077] Step S180: If the road section matches the first preset length interval, combine the road section with an adjacent road section.
[0078] Step S190: If the road segment matches the second preset length interval, cut and determine a first sub-road segment and a second sub-road segment from the road segment, the length of the first sub-road segment is a preset length, and the first sub-road segment The length of the second sub-road segment is the difference between the lengths of the road segment and the first sub-road segment.
[0079] Step S200: Determine a ...
