Dangerous Driving Report Management with Segmented Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reports of dangerous driving often lack clarity in terms of position and date/time, making it difficult for authorities to efficiently manage and investigate such incidents.
Innovation Solution
An information management device that stores report information associating details of dangerous driving incidents with position information, including a candidate range for the occurrence of the incident, and allows for searching and displaying results within predetermined search ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If report information is stored with detailed position data, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments position information into two distinct components: dangerous driving occurrence range candidate (approximate area from reports) and dangerous driving occurrence range (precise area after identification). This segmentation allows the system to store both approximate and precise position data separately, improving measurement precision while managing data structure complexity through organized classification.
2Loss of information
If approximate position ranges are stored for all reports, then loss of information is reduced, but manufacturing precision deteriorates
Solution Approach 1:
The patent applies preliminary action by storing dangerous driving occurrence range candidate (approximate position) at the time of report reception, before actual identification occurs. This preliminary storage preserves position information completeness early in the process, while allowing subsequent refinement to precise coordinates through identification processing, thus balancing information retention with accuracy requirements.

AI summary
In the present invention, reports on dangerous driving from a resident or the like are efficiently managed in driving situation management. A report information storage unit 104 stores report information in which details of a report indicating a dangerous driving situation are associated with position information that includes a dangerous driving occurrence range candidate indicating an approximate range regarding the position of occurrence of the dangerous driving situation and/or a dangerous driving occurrence range indicating a range where the dangerous driving occurrence range candidate has been identified. A search processing unit 101 searches the report information storage unit 104 for the report information in which position information is included in a search range to be searched. A display processing unit 103 outputs a search result.
