Road Degradation Display System with Scale-Adaptive Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Road managers face difficulties in effectively visualizing and prioritizing large amounts of degradation diagnosis results for inspection and repair, as existing systems do not provide an intuitive or easily understandable display of road degradation information.
Innovation Solution
A degradation display system that acquires a degradation index for road sections and adjusts map displays based on range and scale, superimposing information in formats corresponding to the severity of the index, allowing for clear visualization of degradation states in both area and section formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If degradation information is displayed for each road section in detail, then measurement precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The system segments degradation information display based on map scale: when scale is small, it aggregates data by area; when scale is large, it displays by road section. This segmentation allows the system to provide detailed information when needed while maintaining simplicity at broader views, resolving the contradiction between precision and ease of operation.
Solution Approach 2:
The display mode dynamically changes based on map scale. The system automatically switches between area-based aggregation and road-section-based detailed display according to the current zoom level, enabling users to access detailed degradation information when zoomed in while maintaining operational simplicity at overview levels.
2Ease of operation
If degradation information is aggregated by area, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The system applies segmentation by implementing different aggregation levels based on map scale. At small scales, information is aggregated by area for ease of operation; at large scales, it transitions to road-section-level detail, ensuring measurement precision is maintained when users need specific information.
Solution Approach 2:
Different display qualities are applied to different viewing contexts. Area-based aggregation provides a simplified overview suitable for broad viewing, while road-section-based display provides high-quality detailed information for localized inspection, matching information precision to user needs.
3Quantity of substance
If multiple degradation diagnosis results are displayed simultaneously, then information completeness is improved, but device complexity increases
Solution Approach 1:
The system merges multiple degradation diagnosis results by aggregating them at the area level when map scale is small. This combining approach presents comprehensive degradation information in a unified, simplified format, maintaining information completeness while reducing display complexity.
Solution Approach 2:
The system applies partial action by selectively displaying aggregated information at area level rather than showing all individual road section data simultaneously. This provides sufficient information for decision-making without overwhelming the user with excessive detail, balancing completeness with manageable complexity.
