Velocity-Based Travel Segment Filtering for Navigation Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigational aids often overwhelm users with excessive information, increasing cognitive load and distraction by displaying all road segments, including irrelevant ones, making it difficult for users to focus on relevant travel segments during navigation.
Innovation Solution
A system processes traffic and velocity information to filter and present only travel segments within a velocity threshold level, emphasizing relevant road segments based on the user's velocity, using GPS and electronic mapping technologies to provide a comprehensible map display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all road segments are displayed as colored lines on the map, then complete road network information is provided, but user cognitive load increases and navigation focus is lost
Solution Approach 1:
The patent extracts and displays only the relevant travel segments that match the user's velocity characteristics, removing irrelevant road segments from the display. This extraction principle resolves the contradiction by providing complete information when needed (all segments are available in the system) while displaying only essential information (velocity-matched segments) to reduce cognitive load.
Solution Approach 2:
The patent applies different display qualities to different road segments based on their relevance to the user's current velocity. Travel segments with matching velocity characteristics are highlighted with enhanced visual properties, while non-matching segments are dimmed or hidden. This local differentiation resolves the contradiction by maintaining information availability while directing user attention to relevant portions only.
2Reliability
If all road segments are displayed on the map interface, then comprehensive navigation data is available, but user distraction increases and navigation efficiency decreases
Solution Approach 1:
The system extracts and displays only travel segments that match the user's velocity profile, removing distracting irrelevant segments. This maintains navigation reliability by ensuring the displayed segments are actually relevant to the user's current travel conditions, while improving efficiency by reducing visual distraction and cognitive processing requirements.
Solution Approach 2:
The patent dynamically adjusts the map display based on real-time velocity information. As the user's velocity changes, the set of displayed travel segments is dynamically updated to reflect current relevance. This dynamic adaptation ensures navigation reliability by always showing appropriate segments while improving efficiency by adapting to the user's current state and reducing unnecessary visual information.
3Ease of operation
If velocity-based filtering is applied to travel segments, then relevant information is highlighted, but system processing complexity increases
Solution Approach 1:
The system performs self-service by automatically analyzing the user's velocity characteristics and autonomously determining which travel segments are relevant. This eliminates the need for manual user configuration or complex interaction interfaces, thereby improving ease of operation and map readability while the system handles the processing complexity internally through automated velocity-based filtering algorithms.

AI summary
An approach is provided for presenting comprehensible representation of travel segments based, at least in part, on velocity information. The approach involves processing and/or facilitating a processing of traffic information, velocity information, or a combination thereof for one or more travel segments, characteristic information for one or more vehicles, or a combination thereof to determine the one or more travel segments within a velocity threshold level. The approach also involves causing, at least in part, a filtering of the one or more travel segments based, at least in part, on the velocity threshold level. The approach further involves causing, at least in part, a presentation of at least one mapping user interface depicting one or more representations for the one or more travel segments within the velocity threshold level.
