Driving Safety Evaluation System with Periodic Scoring Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems are inadequate in evaluating the safety of a driver's driving operations, particularly in infrequent events like emergency vehicle encounters, and struggle to maintain up-to-date evaluation results, which hampers insurance companies' ability to provide accurate incentives.
Innovation Solution
An information processing system comprising an acquisition unit, determination unit, evaluation unit, and updating unit that acquires and evaluates driving information, compares past and current evaluation results, and updates safety scores based on differences, incorporating features like image data analysis and positional information to assess driving maneuvers such as hazard lamp flickering, deceleration, and avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If evaluation is performed only during the entire traveling period, then the evaluation covers all driving operations, but the evaluation cannot accurately reflect safety in specific low-frequency events such as emergency vehicle encounters
Solution Approach 1:
The evaluation period is segmented into multiple predetermined time intervals (first predetermined period, second predetermined period, etc.). The system acquires and compares evaluation results from different time segments, enabling focused analysis of specific events while maintaining overall safety assessment coverage.
2Reliability
If the system continuously updates evaluation results for all periods, then the latest evaluation data is always available, but the processing load increases significantly
Solution Approach 1:
The system performs partial updates by comparing evaluation results only when necessary. The updating unit acquires evaluation results from different predetermined periods and updates based on comparison, rather than continuously updating all data, thereby reducing processing load while maintaining reliability of latest results.
3Productivity
If the system evaluates all driving operations throughout the traveling period, then comprehensive safety assessment is achieved, but it cannot provide timely updated results for incentive programs
Solution Approach 1:
The system pre-divides the evaluation period into multiple predetermined time intervals and establishes evaluation criteria for each segment in advance. This preliminary structuring enables efficient data collection and comparison across time periods, reducing processing time while maintaining comprehensive assessment coverage for timely incentive program updates.

AI summary
An information processing system includes an acquisition unit configured to acquire traveling information indicating traveling conditions of a first vehicle traveling on a road, a determination unit configured to determine one or more driving operations of a driver driving the first vehicle by using the traveling information acquired when a second vehicle approaches the first vehicle, an evaluation unit configured to perform evaluation of safety related to the driver's driving by using determination results of the determination unit, and an updating unit configured to acquire first evaluation results of the evaluation unit during a first predetermined period to compare the first evaluation results with second evaluation results of the evaluation unit during a second predetermined period before the first predetermined period, and to update the second evaluation results based on comparison results.
