Pedestrian Group Assistance Control for Road-Crossing Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in providing effective traffic assistance for vulnerable pedestrians, particularly when they are moving in conjunction with others, such as friends or family, across roads.
Innovation Solution
An assistance controlling apparatus and method that utilize a network of user terminals, in-vehicle processing units, and image-capturing apparatuses to track the positions and relationships of pedestrians. The system provides traffic assistance by analyzing the movement patterns and interpersonal relationships of users, adjusting the level of assistance based on the degree of companionship and movement coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic assistance is provided for all pedestrians individually, then safety coverage is improved, but system complexity and processing load increase
Solution Approach 1:
The patent merges multiple pedestrian targets into a single grouped target when pedestrians are moving in conjunction with each other. The assistance providing unit provides assistance to the grouped target rather than treating each pedestrian separately, reducing system complexity while maintaining safety coverage for all individuals in the group.
Solution Approach 2:
The system implements a universal assistance mechanism that can handle both individual pedestrians and groups of pedestrians moving together. The assistance providing unit determines whether to provide individual or grouped assistance based on movement patterns, making the system adaptable to different scenarios without requiring separate processing pathways.
2Measurement precision
If traffic assistance is provided for each pedestrian individually, then measurement precision of individual movement is improved, but information processing time increases
Solution Approach 1:
The patent combines movement information of pedestrians who are moving in conjunction with each other into a single grouped target. The assistance providing unit uses the grouped movement data to provide assistance, reducing the number of individual processing operations while maintaining accurate detection of group movement patterns through coordinated analysis of multiple user terminals.
3Measurement precision
If the system tracks all pedestrian positions individually, then positioning accuracy is improved, but communication load increases
Solution Approach 1:
The patent merges position information of pedestrians moving in conjunction into a single grouped target representation. Instead of transmitting and processing individual position data for each pedestrian, the system consolidates their positions into a grouped target, reducing communication data volume while maintaining positioning accuracy for the group as a whole through coordinated data sharing among user terminals.

AI summary
An assistance controlling apparatus includes: an acquiring unit which acquires position information of a plurality of user terminals; an identifying unit which identifies, among the plurality of user terminals, a first user terminal and a second user terminal which are moving at a distance of a predetermined value or less from each other, based on a history of position information of the plurality of user terminals; and an assistance controlling unit which performs control related to assistance for a traffic participant when one of the first user terminal or the second user terminal is detected to move to an opposite side of a road with respect to a position of another of the first user terminal or the second user terminal.
