Abstract

The invention discloses a method and a device for evaluating road alignment similarity based on a perspective drawing principle. On the basis of establishing a road perspective drawing model, point similarity, line similarity and comprehensive similarity are calculated by use of a two-dimensional similarity calculation method respectively, so that the similarity of road alignment inductive effects can be quantified and evaluated. The device designed according to the method comprises eight parts, namely an alignment element extraction module, a parameter setting module, a data importing module, a point similarity calculation module, a line similarity calculation module, a comprehensive similarity calculation module, a data memory module and a data output module, wherein the point similarity calculation module, the line similarity calculation module and the comprehensive similarity calculation module are core modules. The device is convenient for implementing the evaluation of the similarity of different road alignments by using the method, and therefore, convenience and accuracy of alignment inductive effect calculation are improved.

Description

technical field [0001] The invention relates to a road alignment similarity evaluation method and device based on the principle of perspective diagram, belonging to the technical fields of road traffic and data recognition. Background technique [0002] Road alignment design is an important factor to ensure safe road operation. Different road alignment conditions or the same road alignment conditions in different environments have different inductive effects on drivers' driving behavior. In the existing relevant standards and specifications, the relevant regulations are mainly aimed at the design indicators of the surface road alignment. From the perspective of objective design indicators, no systematic quantitative research has been carried out on the differences in the induction effects caused by different alignment indicators. With the gradual deepening of the concept of road design refinement, which kind of alignment effect is more ideal under a certain road space scale ...
