Road Link Danger Ranking for Vehicle Notification Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle accidents often occur due to unexpected sharp curves on roads, as drivers are not adequately informed about upcoming road features, leading to inconsistent interactions and increased accident risks.
Innovation Solution
A system that determines road links with high curvature values and processes curvature, humanized speed, and speed limit information to rank danger levels, prioritizing notifications to vehicles approaching these areas based on the ranking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If notifications are provided to all vehicles about all road features, then drivers receive comprehensive information, but notification overload occurs and critical warnings are lost
Solution Approach 1:
The patent segments road features into different danger levels (safe, cautious, dangerous) based on curvature analysis, and segments notifications into priority levels. This segmentation allows the system to filter and deliver only critical notifications to drivers, preventing notification overload while maintaining information completeness for safety-critical features.
Solution Approach 2:
The patent applies local quality by providing different notification intensities and types to different vehicles based on their specific context (location, speed, proximity to dangerous features). Rather than uniform notifications, the system tailors the quality and urgency of notifications to local conditions, ensuring critical information reaches appropriate drivers without overwhelming the system.
2Reliability
If notifications are provided late to drivers, then system complexity is reduced, but drivers cannot respond in time to avoid accidents
Solution Approach 1:
The patent implements preliminary action by calculating and notifying drivers about dangerous road features before they reach those features. The system uses curvature data and vehicle position to determine upcoming hazards and sends advance warnings, giving drivers sufficient time to slow down and prepare for sharp curves or dangerous intersections, thereby preventing accidents while maintaining timely notification.
3Productivity
If the system monitors and ranks all road links, then notification prioritization is improved, but computational complexity increases
Solution Approach 1:
The patent applies parameter changes by using curvature values as a key parameter to rank road links and prioritize notifications. Instead of analyzing all possible road features equally, the system focuses on curvature as a primary indicator of danger, transforming complex road geometry data into a single ranking parameter that drives notification prioritization efficiently.
Solution Approach 2:
The patent extracts and focuses on the most critical parameter (curvature) from complex road geometry data to drive notification prioritization. By taking out curvature as the key discriminating factor and using it to rank road links, the system simplifies the processing complexity while maintaining effective notification prioritization based on actual danger levels.

AI summary
An approach is provided for prioritizing notification to one or more vehicles based on the ranking of one or more road links. The approach involves determining one or more road links that are associated with at least one curvature value greater than at least one curvature threshold value. The approach also involves determining humanized speed information and speed limit information for the one or more road links. The approach further involves processing and/or facilitating a processing of the at least one curvature value, the humanized speed information, and the speed limit information to determine danger level information for the one or more road links. The approach also involves causing, at least in part, a ranking of the one or more road links based, at least in part, on the danger level information. The approach further involves causing, at least in part, a prioritization of one or more notifications to one or more vehicles approaching or traveling the one or more road links based, at least in part, on the ranking of the one or more road links.
