GPS Traffic Visualization via Color-Coded Road Segment Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPS-based traffic information systems lack efficient methods to visually represent and aggregate data from multiple GPS devices to determine road usage, direction, and speed, limiting their ability to accurately display traffic patterns and navigation routes.
Innovation Solution
A system that collects GPS data from multiple devices, associates it with road segments, and uses color and graphical attributes to represent direction and speed on maps, allowing for the determination of road characteristics like one-way streets, average speed, and turn restrictions through data aggregation and visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GPS data from multiple devices is collected and displayed on maps, then traffic pattern visualization is improved, but data aggregation complexity increases
Solution Approach 1:
The patent combines GPS data from multiple devices by merging location, direction, and speed information into unified visual representations on map displays. This aggregation allows comprehensive traffic pattern visualization while managing complexity through systematic data integration methods
Solution Approach 2:
The system performs multiple functions using the same aggregated data: determining one-way street directions, calculating average speeds, identifying turn restrictions, and detecting stop signs. This multi-functional approach maximizes information utility while minimizing additional data collection complexity
2Loss of information
If color and graphical attributes are assigned to represent travel attributes, then visual indication clarity is improved, but display complexity increases
Solution Approach 1:
The patent assigns different colors to represent various travel attributes such as direction of travel and speed of travel. This color-coding system enables intuitive visual differentiation of multiple data dimensions without requiring complex graphical interfaces or additional display elements
Data Source
AI summary
Maps are created that display representations of GPS data generated from a plurality of GPS devices. The GPS data received from the GPS devices is embodied as a representation having descriptive features that visually indicate the location, direction of travel, and speed of travel of the GPS device, and the representation is associated with a road segment on the map. The display of the GPS data from a plurality of GPS devices can be used for editing information about roads on maps and determining preferred routes.
