Road Condition Transmission Using Directional Segment Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road condition information transmission systems provide low accuracy as they only send information about the road ahead, not accounting for the user's current driving direction, leading to inconvenient manual adjustments by users.
Innovation Solution
A method and apparatus that determine a target subsequent road segment based on recorded road segment information, including attributes like length and recording times, to transmit accurate road condition information to the user, aligning with their driving direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the server only sends road condition information of the road ahead to the client, then the system complexity is reduced, but the accuracy of the road condition information sent to the client deteriorates
Solution Approach 1:
The patent applies local quality by determining the target subsequent road segment based on the client's current driving direction and sending road condition information specifically for that segment. Instead of treating all road segments uniformly, the system identifies and prioritizes the specific road segment that the client will actually traverse, thereby improving information accuracy without significantly increasing system complexity.
2Measurement precision
If the server sends road condition information for multiple candidate road segments, then the accuracy of information is improved, but the quantity of information transmitted increases
Solution Approach 1:
The patent extracts only the necessary road condition information for the target subsequent road segment determined by the client's driving direction. By filtering out information for other candidate road segments that the client is not currently headed towards, the system maintains high information accuracy while minimizing the quantity of data transmitted to the client.
3Measurement precision
If the server uses recorded road segment information to determine the target subsequent road segment, then the accuracy of road condition information is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary actions by maintaining recorded road segment information that includes attributes such as length and recording times. This pre-processed data allows the server to quickly determine the target subsequent road segment by comparing candidate segments against the recorded information, reducing the processing time required at the moment of information transmission while maintaining high accuracy.
