Pavement Condition Mapping with GPS-Linked Audio and Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pavement condition monitoring systems are limited in their ability to efficiently and accurately capture and present data on large areas, requiring manual review of video files to identify conditions, which hinders quick inspection and prioritization of repairs.
Innovation Solution
An asset management mapping system that integrates a global positioning system with a condition signal generator and keypad selectors to record audio comments and video, associating condition signals with GPS locations, allowing for the creation of a database and visual map indicating pavement conditions, enabling quick review and prioritization of repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual review of video files is used to identify pavement conditions, then detailed condition assessment can be achieved, but inspection efficiency and speed are reduced
Solution Approach 1:
The patent replaces manual video review with automated image processing and analysis systems. Computer vision algorithms automatically detect and classify pavement conditions from captured images, eliminating the need for manual video file review while maintaining assessment accuracy and significantly improving inspection speed.
Solution Approach 2:
The system creates digital copies of pavement conditions through photography and stores them in a database. These digital representations can be automatically analyzed and reproduced on maps, allowing rapid assessment without reviewing original video files while preserving detailed condition information.
2Loss of information
If comprehensive condition data is collected across large areas, then complete pavement inventory knowledge is achieved, but data processing time and complexity increase
Solution Approach 1:
The patent divides the pavement assessment into standardized condition categories and uses GPS to segment the geographic area into manageable zones. This segmentation allows comprehensive data collection to be processed in discrete, organized units, reducing overall processing complexity and time while maintaining complete inventory coverage.
Solution Approach 2:
The system transforms raw condition data into standardized parameters and codes that can be efficiently processed and stored. By converting diverse pavement conditions into uniform data structures with specific parameters, the system enables rapid processing of large datasets while preserving complete inventory information.
3Ease of operation
If visual maps with condition indicators are generated, then quick review and prioritization is enabled, but system complexity increases
Solution Approach 1:
The patent uses color-coded indicators on maps to represent different pavement conditions. This visual encoding system allows rapid interpretation of pavement status and prioritization of repairs without complex data analysis, improving ease of operation while the underlying system handles the complexity of data processing automatically.
Solution Approach 2:
The system introduces an intermediary processing layer that automatically generates simplified visual representations from raw condition data. This intermediary map generation process handles the complexity internally while presenting simplified, easy-to-interpret visual information to users, improving review efficiency without exposing users to system complexity.

AI summary
An asset management mapping system including a microphone recording the audio of the asset inspector and a condition signal generator generating an condition signal based on asset inspector input from a keypad including condition selectors recorded into a global positioning system recorder that associates the audio, condition signal, and video with a gps location to create a pavement condition database. The database is interpreted to generate a condition output map of the areas inspected and provide associated video of each location on the map.
