Embodiment Construction

[0022] The principles and features of the present invention will be described below with reference to the accompanying drawings. The embodiments are only used to explain the present invention, but not to limit the scope of the present invention.

[0023] like figure 1 As shown, it is a schematic flowchart of an embodiment of a road surface technical condition prediction method according to the present invention, and the prediction method includes:

[0024] S1: Acquire historical technical conditions within a preset annual range of each road section in the target area road network, and calculate an initial technical condition distribution matrix of the target area road network according to the historical technical conditions.

[0025] It should be understood that at least 2 years of data need to be obtained to obtain the transition probability matrix. For example, historical technology conditions for the current year, as well as adjacent years in the past, can be obtained.

Abstract

The invention discloses a road surface technical condition prediction method, which relates to the field of comprehensive road surface maintenance. Including: obtaining the historical technical conditions within the preset annual range of each road section in the target area road network, and calculating the initial technical condition distribution matrix of the target area road network according to the historical technical conditions; In the case of , the first transition probability matrix of the technical condition distribution of the road network in the target area; the second transition probability matrix of the technical condition distribution of the road network in the target area under the condition that the road network in the target area is maintained according to the maintenance mode is calculated. ; Calculate the technical condition of the pavement in the preset year. The invention realizes in-depth analysis and effective utilization of the technical condition data resources of the historical road network, can automatically predict the road technical condition in the future years, and has the advantages of more comprehensive analysis scope and more reasonable and accurate prediction results.

Description

technical field [0001] The invention relates to the field of comprehensive maintenance of pavement, in particular to a method for predicting the technical condition of pavement. Background technique [0002] The technical condition of highway includes evaluation contents such as pavement, subgrade, bridge and tunnel, among which, the technical condition of pavement is used to evaluate the cracks, cracks, potholes and other damages of the pavement. [0003] At present, for the technical condition prediction of pavement, technicians predict the technical condition of pavement in a specified year based on historical data, which is highly subjective, resulting in inaccurate prediction results and large forecast workload. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a method for predicting the technical condition of the road surface in view of the deficiencies of the prior art. [0005] The technical scheme that th...
