Intersection Proximity Detection for Vehicle Stop Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information providing devices struggle to accurately notify drivers of recommended stopping information, especially when multiple intersections with traffic signals are in close proximity, leading to potential confusion.
Innovation Solution
An information providing device equipped with an external environment recognition unit, information providing control unit, and determination unit that assesses the proximity of intersections and prevents notification of recommended stopping information from secondary intersections when they are too close, ensuring clear and accurate alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If recommended stopping information is provided for all traffic signals, then completeness of information is improved, but accuracy and clarity deteriorate when intersections are in close proximity
Solution Approach 1:
The system applies different notification strategies to different intersections based on their relative positions. When a second intersection is detected within a predetermined distance from the first intersection, the notification for the second intersection is suppressed. This local differentiation ensures that only the most relevant stopping information (from the nearest intersection) is presented to the driver, maintaining both completeness and accuracy.
2Adaptability or versatility
If notification is provided for all detected traffic signals, then information coverage is improved, but driver confusion increases when multiple intersections are nearby
Solution Approach 1:
The system performs preliminary detection and distance calculation between intersections before generating notifications. By determining in advance whether a second intersection falls within the predetermined distance threshold from the first intersection, the system can proactively suppress potentially confusing notifications, preventing driver confusion before it occurs while still maintaining comprehensive information coverage.

AI summary
An information providing device includes an external environment recognition unit that recognizes an external environmental situation of a movable body, an information providing control unit that provides a notification of recommended stopping information based on a current indication of traffic signals recognized by the external environment recognition unit, and a determination unit which determines, in the case that a first intersection and a second intersection are positioned in a travel direction of the movable body, whether or not a degree of proximity of the first intersection and the second intersection satisfies a predetermined condition. In the case it is determined by the determination unit that the predetermined condition is satisfied, the information providing control unit prevents the recommended stopping information based on a current indication of the traffic signal belonging to the second intersection from being provided.
