Abstract

The invention discloses a grid-based highway vehicle screening method, comprising the following steps: 1, acquiring highway section information of highways, thus a highway section information set A isobtained; 2, acquiring highway section longitude and latitude information of highways in a required computational area, thus a highway section longitude and latitude information set B is obtained; 3,initializing a highway section grid eigenvalue dictionary C; 4, calculating a minimum value of longitudes of all the highway sections in the highway section longitude and latitude information set B and a minimum value of latitudes of all the highway sections in the highway section longitude and latitude information set B; 5, defining a grid size Glen; 6, for each highway section in the highway section longitude and latitude information set B, sequentially processing longitude and latitude information of the highway section; 7, acquiring vehicle location information in the computational area,thus a vehicle location information set D is obtained; 8, initializing a highway section vehicle set E; 9, processing the vehicle location information in the set D, and storing data meeting conditionsinto the set E; and 10, exporting the data in the set E.

Description

technical field [0001] The invention belongs to the technical field of transportation, in particular to a grid-based expressway vehicle screening method. Background technique [0002] At present, when processing regional vehicle positioning data, the electronic fence method is usually used to distinguish whether the vehicle is on the expressway or on the ordinary road. Due to the unstable direction of the expressway and the large number of electronic fences, it is troublesome to set up electronic fences, and the screening speed is very slow when there are many electronic fences. [0003] When the area is large and the number of vehicles is large, it is difficult to guarantee the real-time performance of data processing, and it is difficult to accurately and quickly collect vehicle information in expressway sections, resulting in a decline in the overall performance of data processing. Contents of the invention [0004] Purpose of the invention: The technical problem to be...
