Dynamic Lane Guidance Ribbon for Intersection Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to provide intuitive and granular lane-based route guidance, requiring users to switch between route guidance and separate lane assistance graphics, leading to driver distraction and complexity.
Innovation Solution
A dynamic lane level route ribbon is introduced, integrating route and lane guidance using varying widths and colors based on road segment speed limits, vehicle speed, and traffic conditions, allowing users to follow the appropriate lanes without diverting attention from the primary route display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate lane assistance graphics are provided alongside route guidance, then lane-level navigation information is available, but driver distraction and interface complexity increase
Solution Approach 1:
The patent combines route guidance and lane assistance graphics into a single integrated display. The route guidance ribbon is rendered to span across multiple lanes, visually indicating which lanes are appropriate for following the route, thereby eliminating the need for separate lane assistance graphics and reducing interface complexity while maintaining comprehensive navigation information
2Loss of information
If users switch between route guidance and lane assistance graphics, then complete navigation information is obtained, but driver attention is diverted
Solution Approach 1:
The system merges route guidance and lane information into a single visual element - the route guidance ribbon that extends across multiple lanes. This integration allows drivers to obtain both route direction and lane selection information simultaneously from one display, eliminating the need to switch between separate graphics and reducing driver distraction
3Device complexity
If a single route guidance ribbon is used, then interface simplicity is maintained, but granular lane-based guidance is insufficient
Solution Approach 1:
The patent applies local quality by varying the width of the route guidance ribbon across different horizontal positions. The ribbon spans across multiple lanes with different widths at different locations, where wider sections indicate multiple acceptable lanes and narrower sections indicate more specific lane requirements, thereby providing granular lane-level guidance within a simple unified interface
Data Source
AI summary
A method is provided for gathering probe data and using the gathered data to establish traffic speeds for various paths through an intersection. Methods may include receiving probe data from a plurality of probes approaching an intersection along a common road segment; receiving probe data from the plurality of probes exiting the intersection along two or more different road segments; determining traffic speed for each path through the intersection from the common road segment based on the received probe data from the plurality of probes approaching the intersection along the common road segment and the received probe data from the plurality of probes exiting the intersection along two or more different road segments; and generating an indication of the traffic speed for each path through the intersection to be provided for display on a graphical representation of the intersection.
