Road Surface Inspection Planning for Fresh Slippery-Road Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for estimating road surface conditions rely on outdated information, leading to potential safety risks due to changing road conditions, particularly slippery surfaces, which can compromise vehicle safety.
Innovation Solution
A method and system for inspecting road surface conditions that utilize real-time data from a vehicle's traveling record to generate inspection plans, prioritize inspection points based on predicted changes, and update information dynamically to maintain freshness, incorporating weather and environmental data, and adjust vehicle operations for safe and effective inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If road surface condition estimation uses traveling record information, then the estimation can be performed, but the information becomes outdated and loses freshness
Solution Approach 1:
The system performs preliminary inspection actions by sending the vehicle to specifically inspected locations ahead of time to obtain fresh road surface condition information before it is needed for decision-making, preventing information from becoming outdated
Solution Approach 2:
The system establishes a feedback loop where road surface condition information is continuously obtained from traveling records, evaluated for freshness, and used to trigger new inspections when the information becomes outdated, ensuring continuous updates
2Productivity
If inspection points are selected without priority ordering, then all inspection points can be covered, but the inspection efficiency decreases when multiple points are in range
Solution Approach 1:
The system applies different priority levels to different inspection points based on their specific characteristics and urgency, allowing the vehicle to focus on high-priority points first while maintaining the ability to cover all points systematically
Solution Approach 2:
The system pre-calculates and stores priority orders for multiple inspection points before the vehicle arrives, allowing efficient real-time decision-making without complex calculations during execution
3Reliability
If inspection execution plan is generated for all inspection points in range, then comprehensive coverage is achieved, but the vehicle operation becomes complex and time-consuming
Solution Approach 1:
The system segments the inspection execution plan into priority-based stages, where high-priority inspection points are executed first, followed by lower-priority points if time and conditions permit, breaking down the complex overall task into manageable segments

AI summary
A method for inspecting a road surface condition includes the steps of obtaining detailed information on a road surface condition set for each inspection point based on a traveling record of a vehicle, and information on an own position of the vehicle, generating an inspection execution plan of the vehicle in the inspection point when the inspection point is included in a predetermined range in an advancing direction of the vehicle with the own position as a reference, performing evaluation of a road surface condition in the inspection point based on a traveling condition of the vehicle that is obtained during the inspection execution plan, and updating the detailed information on a road surface condition set for the inspection point based on latest information on the road surface condition the evaluation of which is performed.
