Maintenance history-based road section division method, system and equipment and storage medium

Abstract

The invention discloses a road section division method, system and equipment based on maintenance history and a storage medium, and the method comprises the steps: 1, dividing a road into a plurality of road sections, measuring six index characteristic variable values of each road section, and listing the six index characteristic variable values of all the road sections as a matrix; 2, setting each road section as one class, combining two road sections with the most similar index characteristic variable values into a new class, re-calculating the spatial distances between the new class and other classes, combining the two classes with the closest spatial distances until all the road sections become one class, and obtaining a classification result according to the determined class number; 3, obtaining a system clustering number atlas according to the distance between the classes, and obtaining different clustering results through the system clustering number atlas; and adopting a clustering result with a contour coefficient of 0.25-1 to obtain a classification number of the clustering result and a road section corresponding to each class. And the historical maintenance conditions of different road sections can be considered, so that the division result better conforms to the actual condition.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to a method, system, equipment and storage medium for dividing road sections based on maintenance history. Background technique [0002] The traditional asphalt pavement maintenance section division method mainly considers objective factors such as road grade, pavement structure and type, traffic volume, large vehicle mixing rate, climate and environment, and the attributes of the road itself, such as road damage types, rutting, and deflection. However, although this method is simple and easy to operate, it ignores the randomness of road surface damage. For example, the calculated damage rate of a certain unit length road section is very small, but in fact the damage rate of the road surface in some small areas of the segment may be Therefore, the calculation results of this traditional method are often quite different from the actual situation.
