Road Deterioration Diagnosis for Customized Inspection Frequency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection systems for road deterioration lack the ability to provide tailored inspection frequencies for different sections of roads, as these frequencies are uniformly set and do not account for varying traffic volumes, vehicle types, and environmental conditions.
Innovation Solution
A deterioration diagnosis device and system that calculates an appropriate inspection frequency for each section of a road by storing a history of deterioration degrees, calculating deterioration speeds, acquiring reference information, and using this data to determine the optimal inspection frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform inspection frequency is set for all roads, then inspection management is simplified, but inspection appropriateness deteriorates
Solution Approach 1:
The patent segments the road network into multiple sections based on geographic boundaries (e.g., wards, districts) and assigns different inspection frequencies to each section. This segmentation allows the system to move from a uniform inspection approach to a customized approach where each road section receives inspection frequency tailored to its specific deterioration characteristics, traffic conditions, and environmental factors.
Solution Approach 2:
The patent implements local quality by calculating and applying different inspection frequencies to different road sections based on their local characteristics. Each road section's inspection frequency is determined by its specific deterioration speed, traffic volume, vehicle type composition, and environmental conditions, rather than applying a single uniform frequency across all roads.
2Measurement precision
If inspection frequency is increased for all roads, then deterioration detection capability is improved, but resource efficiency deteriorates
Solution Approach 1:
The patent changes the parameter of inspection frequency from a fixed uniform value to a variable value that is calculated based on multiple factors including deterioration speed, traffic volume, vehicle type composition, and environmental conditions. This parameter change allows the system to optimize inspection frequency for each road section, improving deterioration detection where needed while avoiding unnecessary inspections where deterioration is slow.
3Reliability
If customized inspection frequency is calculated for each road section, then inspection appropriateness is improved, but system complexity increases
Solution Approach 1:
The patent implements universality by creating a comprehensive evaluation system that handles multiple functions within a unified framework. The system simultaneously processes deterioration history data, traffic volume data, vehicle type composition data, and environmental condition data to calculate inspection frequencies for multiple road sections. This multi-functional approach manages system complexity by providing a standardized methodology that can be applied across the entire road network.
