Travel Data Compliance Filtering for Accurate Map Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to adequately update map data when illegal vehicles violate traffic rules, leading to inaccurate representation of unregistered roads or passable roads during disasters.
Innovation Solution
A control device that acquires travel data, analyzes it for traffic rule compliance, and adjusts its usage based on compliance status to generate accurate map information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If travel data from all vehicles is used to update map data, then map data coverage is improved, but data accuracy deteriorates due to inclusion of illegal route information
Solution Approach 1:
The system extracts and separates compliant travel data from non-compliant travel data based on traffic rule verification. Only travel data that adheres to traffic rules is selected for map data updates, while illegal route data is excluded. This extraction process resolves the contradiction by maintaining comprehensive coverage through multiple data sources while ensuring accuracy through selective usage of only compliant data.
2Productivity
If travel data is used without verification, then data processing efficiency is improved, but reliability of map data deteriorates
Solution Approach 1:
The system performs preliminary verification of travel data against traffic rules before the data is used for map updates. By checking compliance in advance and only selecting verified compliant data, the system ensures high reliability of map data while maintaining efficient processing through automated verification workflows that prevent manual review of all data.
3Loss of time
If unverified travel data is used for map updates, then update speed is improved, but measurement precision of road information deteriorates
Solution Approach 1:
The system implements a feedback mechanism where travel data is automatically verified against traffic rules and existing map data before being accepted for updates. This closed-loop verification process ensures that only accurate and compliant road information is incorporated into map data, maintaining high measurement precision while achieving fast update speeds through automated decision-making that eliminates manual verification delays.

AI summary
A control device includes a processor that acquires travel data of a target vehicle, determines whether the target vehicle obeys a traffic rule, and adjusts a usage form of the travel data in a case of determining that the target vehicle does not obey the traffic rule.
