Traffic Light Output for Turn-Specific Intersection Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for displaying traffic light information at intersections often result in insufficient clarity and intuitiveness due to the simultaneous display of multiple directions, leading to confusion for users.
Innovation Solution
A method and apparatus that acquire guidance information and positioning data to determine the relevant traffic light information for the intended direction of travel, focusing on a single signal light information piece when the vehicle approaches an intersection, thereby avoiding the display of multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple signal light information pieces for different directions are displayed simultaneously, then comprehensive traffic information is provided, but clarity and intuitiveness deteriorate causing user confusion
Solution Approach 1:
The patent extracts and displays only the signal light information relevant to the vehicle's current traveling direction, removing unnecessary information for other directions. This is achieved by determining the vehicle's traveling direction and selectively displaying signal light information corresponding to that direction, thereby maintaining clarity while providing comprehensive information for the relevant path
Solution Approach 2:
The patent applies local quality by differentiating the display content based on the vehicle's traveling direction. Different signal light information is displayed for different traveling directions (straight, left turn, right turn), ensuring that the information presented is locally optimized for the specific direction the vehicle is heading, thus improving both comprehensiveness and clarity
2Quantity of substance
If signal light information for all directions is displayed, then complete intersection information is available, but user understanding deteriorates due to information overload
Solution Approach 1:
The system extracts only the necessary signal light information corresponding to the vehicle's intended traveling direction from the complete set of intersection signal lights. By filtering out information for directions not relevant to the current travel path, the system maintains complete information availability for the relevant direction while preventing user confusion from unnecessary information
Solution Approach 2:
The patent applies partial action by displaying only a subset of the available signal light information - specifically, only that which is relevant to the current traveling direction. This selective display approach provides sufficient information for safe driving decisions without the excess information that would overwhelm the user

AI summary
The present disclosure provides a method, apparatus for outputting signal light information, relates to the field of artificial intelligence, and specifically, relates to the technical fields of intelligent transportation and driving assistance. A specific implementation includes: acquiring guidance information and positioning information of a terminal, where the guidance information includes a turning information piece of a turning at a nearest intersection along a traveling direction of the terminal; acquiring information pieces of a signal light at the nearest intersection of the terminal; determining, in response to determining that the terminal satisfies a preset position condition based on the positioning information, from the signal light information pieces, a signal light information piece corresponding to the turning information piece in the guidance information, and using the signal light information piece as a target signal light information piece; and outputting the target signal light information piece. The present disclosure can display the signal light information piece of the direction to be traveled, avoiding the problems of insufficient clarity and intuitiveness caused by displaying the signal light information pieces of multiple directions at the same time.
