Navigation Device Traffic Line Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices struggle to clearly display relationships between traffic lines and roads, especially in areas with multiple expressways or roads that intersect, leading to hidden or unclear traffic line representations.
Innovation Solution
The system visually separates roads and their corresponding traffic lines when they are close or connected, using a simple road graphic screen display to differentiate between congested and normal traffic conditions, allowing users to easily recognize relationships between roads and traffic lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traffic lines are displayed along individual expressways around ramps where multiple expressways are concentrated, then traffic information coverage is improved, but the relationships between traffic lines and expressways become unclear due to overlapping and mixing
Solution Approach 1:
The patent segments the display by separating expressways into different groups based on their spatial relationships. Expressways that are close to each other are displayed in a separated manner to avoid overlap, while those that are farther apart can be displayed more closely. This segmentation allows traffic lines to be clearly associated with their corresponding expressways without visual confusion.
Solution Approach 2:
The patent introduces a new dimension to the display by adjusting the vertical positioning of expressways in the graphical representation. By separating expressways that are close to each other in the vertical dimension, the patent prevents traffic lines from overlapping and becoming indistinguishable, thereby maintaining clear relationships between traffic information and road geometry.
2Area of stationary object
If multiple expressways are displayed in close proximity, then map space utilization is improved, but traffic lines may be hidden by other expressways and relationships become unclear
Solution Approach 1:
The patent applies segmentation by dividing expressways into distinct visual groups based on their proximity relationships. When expressways are close to each other, they are separated in the display to prevent traffic lines from being hidden. This ensures that each traffic line remains clearly visible and associated with its corresponding expressway, maintaining reliable traffic information recognition.
Solution Approach 2:
The patent uses color changes to differentiate between multiple expressways and their corresponding traffic lines. By assigning distinct colors or color patterns to different expressways, the patent ensures that traffic lines remain distinguishable even when expressways are displayed in close proximity, thereby maintaining reliable traffic line recognition without sacrificing map space efficiency.

AI summary
A navigation device and a traffic line display method which make a user reliably recognize the relationships between traffic lines and roads when the traffic lines are displayed so as to correspond to the roads which are positioned near one another in a concentrated manner or connected to one another are provided. When the roads currently displayed include roads which belong to a certain road type and which are positioned near one another within a predetermined distance or connected to one another and when at least one of the roads has heavy traffic, the vicinity/connection roads positioned near one another within a predetermined distance or connected to one another and the corresponding traffic lines are clearly distinguished from one another by displaying the roads and the corresponding traffic lines so as to be visually separate from one another. Accordingly, the relationships between the traffic lines and roads are reliably recognized.
