3D Flythrough Traffic Map with Weather Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic reporting systems lack the ability to provide detailed, real-time traffic information integrated with weather data and do not allow users to interactively view traffic conditions in a dynamic, 3D flythrough mode, limiting their effectiveness in conveying accurate and comprehensive traffic updates.
Innovation Solution
The integration of weather data into graphical maps of road systems, enabling real-time, 3D flythrough views of traffic flow data along user-selected routes, with continuous rendering and adjustable zoom levels, and the display of congestion status on keyroutes, allowing for enhanced user interaction and comprehension of traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional traffic reporting systems are used, then traffic information is provided in a generalized manner, but detailed real-time traffic information and weather data integration are lacking
Solution Approach 1:
The patent combines multiple data sources including traffic flow data, weather data, and road system data into a single integrated graphical map display. This merging of previously separate information streams allows detailed real-time traffic information and weather conditions to be presented together in a unified visual interface, resolving the contradiction between providing comprehensive information and maintaining system simplicity.
Solution Approach 2:
The graphical map system is designed to display multiple types of information simultaneously - traffic flow conditions, weather data, road system geometry, and user-selected objects of interest. This multi-functional capability allows a single system to provide generalized traffic reports while also delivering detailed real-time information about specific locations, incidents, or routes without requiring separate specialized systems.
2Ease of operation
If static traffic maps are displayed, then information is easy to comprehend, but user interaction and dynamic viewing are limited
Solution Approach 1:
The patent implements dynamic viewing capabilities including 3D flythrough modes that allow users to virtually travel along roadways, adjustable zoom levels for different areas of interest, and real-time updates as traffic and weather conditions change. These dynamic features transform static maps into interactive experiences while maintaining ease of use through intuitive controls and automatic rendering.
Solution Approach 2:
The system transitions from traditional 2D static maps to 3D dynamic visualizations with flythrough capabilities. By adding the third dimension and temporal dynamics, the system provides enhanced user interaction and immersion while maintaining comprehension through familiar map-based interfaces and automatic camera positioning along roadways.
3Measurement precision
If real-time traffic data is continuously updated, then accuracy is improved, but rendering time and processing load increase
Solution Approach 1:
The patent implements continuous real-time rendering where the graphical map is constantly updated as new traffic and weather data arrives. The system maintains persistent display state and only re-renders portions of the map that have changed, allowing continuous accurate information delivery without complete re-rendering of the entire map each time data updates.
Solution Approach 2:
The system updates and re-renders only the specific portions of the graphical map where changes have occurred - such as a particular roadway segment experiencing traffic conditions or a local weather event - rather than re-rendering the entire map. This localized updating approach maintains high data accuracy while significantly reducing processing time and computational load compared to full map re-rendering.
Data Source
AI summary
Traffic flow data is obtained for a road system that encompasses a predefined geographical region. A user then selects an object of interest within the geographical region. The object of interest has a corresponding geographical location. A graphical map of the road system is then created and the traffic flow data representing traffic conditions on the road system is displayed on the graphical map, wherein the graphical map includes the geographical location of the user-selected object of interest.
