Road Network Map Validation with Location-Bounded Legal Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road network maps used by navigation systems and autonomous vehicles lack the ability to ensure compliance with location-specific legal requirements, leading to potential violations of traffic laws when modifying or validating map elements.
Innovation Solution
A system and method that processes modification or validation requests for road network maps based on location-specific rules, comparing requested changes to a set of rules associated with the bounded area, allowing only valid modifications that comply with local laws and inhibiting invalid ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cartographers manually annotate and update road network maps without automated validation, then map updates can be made flexibly and quickly, but the maps may contain errors that violate location-specific legal requirements
Solution Approach 1:
The system performs preliminary validation of map modifications against location-specific rules before the changes are committed to the map database. The validation server checks proposed modifications against stored legal requirements for different geographic areas, preventing non-compliant changes from being applied. This advance checking ensures legal compliance without requiring manual review while maintaining update efficiency.
2Reliability
If the system validates every map modification against location-specific rules, then legal compliance is ensured, but the validation process increases processing time and system complexity
Solution Approach 1:
The system introduces a validation server as an intermediary component that specialized in handling rule-based validation. This server maintains databases of location-specific legal requirements and provides validation services to the map editing system. By separating the validation function into a dedicated intermediary service, the system ensures comprehensive legal compliance checking while keeping the core map editing system relatively simple and modular.
3Measurement precision
If the system stores comprehensive location-specific rules for all bounded areas, then validation accuracy improves, but the data storage requirements and processing overhead increase
Solution Approach 1:
The system organizes legal requirements as location-specific rules associated with bounded geographic areas. Each bounded area has its own set of applicable rules, allowing the system to store only the relevant rules for each location rather than maintaining a monolithic rule set. When validating a modification, the system retrieves only the rules applicable to that specific location, improving validation accuracy while managing data storage efficiently through localized rule sets.
Data Source
AI summary
Systems and methods are provided where requests to modify or validate a road network map are received, and a determination is made as to whether a requested modification, or the road network map, is invalid based on a location at which the modification is desired to be made, and rules associated with a corresponding bounded area of the road network map to which the location belongs. Where a requested modification, or the road network map, is determined to be invalid, the modification is inhibited, or a notification is displayed to a user that the road network map violates the set of rules.
