Embodiment Construction

[0042] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] The following will refer to figure 2 Turning to FIG. 5 , each step in the specific implementation of a method for setting up expressway multi-path identification sign stations of the present invention is described in detail.

[0044] The first step is to collect road network data. Collect road network topology, names of hubs, mileage between hubs, road section management units, road section names, etc. figure 2 A road network diagram is shown.

[0045] The second step is to mark the road network data. image 3 The road network graph after labeling is shown. ...

Abstract

An expressway multi-path identification sign station setting method includes the following steps: (1) collection of road network information; (2) marking of the road network information; (3) analysis of the composition of basic loop operation and management units; (4) elimination of triangular basic loops; (5) competitive path analysis; (6) analysis of sign station-setting locations. Because the method adopts an 'opposite sign station setting' principle on basic loops with competitive paths, a toll-dividing scheme can be more reliable and reasonable; the division of multi-path toll without sign information can be more reasonable; and the method can satisfy an economical setting scheme under the condition of reliable multi-path toll division.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for setting up expressway multi-path identification sign stations. Background technique [0002] For the expressway system with tolls, it is necessary to analyze the multipath of the expressway and provide a reliable and economical identification station setting scheme for the multipath identification system to distinguish the multipath of the expressway, so as to solve the problem of multipath tolls in the expressway. Splitting among different owners. [0003] At present, there are two main types of roads used for expressway multi-path identification technology: the first type is the shortest path toll (minimum toll amount) + probability split technology, and the second type is precise identification technology. Among them, accurate identification technologies include civil engineering identification station method, RFID-based composite pass card method, and l...
