Map Data Updating via Traffic Event Text Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating electronic maps are costly, inefficient, and lack timely updates, which can affect navigation accuracy and reliability.
Innovation Solution
A method for updating map data involves acquiring traffic event texts with location and direction data, determining candidate road data, identifying target road data based on the direction data, and updating the target road data accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional methods are used to update electronic map data, then comprehensive map coverage can be maintained, but the updating cost is high and the efficiency is low
Solution Approach 1:
The patent extracts only the necessary information from traffic event texts (location data and reference direction data) rather than processing entire map datasets. This selective extraction approach reduces computational resources and updating costs while maintaining update efficiency
Solution Approach 2:
The patent segments the map updating process into distinct steps: acquiring traffic event text, determining candidate road data based on location, identifying target road data using reference direction, and updating only the specific target roads. This segmentation avoids processing entire map datasets and reduces overall updating cost and time
2Reliability
If traditional methods are used to update electronic map data, then map data can be updated, but the updating is not timely enough to affect navigation accuracy
Solution Approach 1:
The patent performs preliminary processing of traffic event texts to extract location and direction data before actual map updating. This preparation enables rapid identification and updating of affected road segments when events occur, ensuring timely updates without compromising navigation accuracy
Solution Approach 2:
The patent implements a dynamic updating mechanism that responds to real-time traffic events. By continuously monitoring traffic event texts and immediately updating affected road segments, the system adapts to changing conditions promptly, maintaining high navigation accuracy without fixed scheduling delays
