Vehicle Alert Control Using Student Category Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems for pedestrians, wheelchairs, and bicycles lack effective alerts for students, especially at night when it is difficult to recognize them, leading to potential safety hazards.
Innovation Solution
An alert system that uses a mobile edge computing server to collect and analyze position history data to identify students, and then provides real-time alerts to vehicles through image recognition and category-based alerts, enhancing traffic safety by distinguishing between students and other pedestrians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation systems provide general alerts for all pedestrians, then basic safety information is provided, but the system cannot distinguish students from other pedestrians leading to insufficient safety protection
Solution Approach 1:
The alert control apparatus segments pedestrians into different categories (students and non-students) based on position history data and category information. This segmentation allows the system to provide differentiated alert strategies, issuing alerts more frequently or with higher priority when students are detected, thereby improving safety protection while maintaining efficient information processing.
Solution Approach 2:
The system performs preliminary classification of pedestrians by analyzing position history data and category information before generating alerts. By pre-identifying students through their movement patterns and stored category data, the system can prepare appropriate alert responses in advance, ensuring that when a student is detected, the alert is immediately optimized for their safety needs.
2Reliability
If the system monitors all pedestrians with equal alert frequency, then comprehensive coverage is achieved, but students who are harder to recognize especially at night receive insufficient attention
Solution Approach 1:
The alert control apparatus uses position history data and category information as intermediary elements to identify students without requiring complex real-time visual recognition. By mediating through stored movement patterns and pre-categorized data, the system can reliably distinguish students from other pedestrians using simpler sensors and processing, reducing detection complexity while improving student detection accuracy.
Solution Approach 2:
The system creates a digital copy of student characteristics through position history data and category information stored in databases. Instead of relying on complex real-time visual recognition, the system uses these data copies to identify students based on their movement patterns and previously stored information, simplifying the detection mechanism while maintaining high accuracy in identifying students especially in low-visibility conditions.
3Productivity
If the system issues alerts based on general pedestrian detection, then basic alert coverage is provided, but alert timing and frequency cannot be optimized for student safety
Solution Approach 1:
The alert control apparatus segments alert generation into different protocols for students and non-students. By categorizing pedestrians and applying differentiated alert strategies, the system optimizes alert response efficiency for students through more frequent or earlier alerts when their movement patterns match historical student data, while maintaining appropriate alert levels for other pedestrians.
Solution Approach 2:
The system uses position history data and category information as feedback mechanisms to continuously refine alert timing and frequency. By monitoring student movement patterns and comparing them against historical data, the system adjusts alert generation in real-time, providing optimized alert responses that are specifically tuned to student safety needs while maintaining efficient overall system operation.

AI summary
An alert control apparatus includes: an alert control unit to issue a first alert to an occupant in a moving body if an object in a particular category is present within a region to which the moving body is headed, and issue a second alert to the occupant if an object in a category other than the particular category is present within the region; a reception control unit to perform, when the moving body enters a new movement section on a movement route, control for receiving a category of an object present within the new movement section from an external apparatus. If there is an object for which an alert is to be issued during movement within the new section, the alert control unit, based on the category received from the external apparatus, controls as to which of the first and second alerts is to be issued.
