Navigation Device Predictive Traffic Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying predictive traffic information in navigation systems require users to select multiple future points in time to estimate delays, which is time-consuming and distracting, potentially compromising safety due to the need for extensive information analysis.
Innovation Solution
A method that determines and displays predictive traffic information for multiple road segments based on their estimated time of passing, using factors like distance, velocity, and road hierarchy, allowing for a comprehensive spatio-temporal overview without the need for user selection, while optimizing computational resources through techniques like static and dynamic road network searches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If predictive traffic information is displayed for multiple future points in time to provide comprehensive overview, then information completeness is improved, but user distraction and time consumption increase
Solution Approach 1:
The system automatically determines and displays predictive traffic information for multiple future points in time without requiring user selection. The navigation device proactively calculates estimated times of passing for multiple road segments and retrieves corresponding predictive traffic information in advance, presenting a comprehensive temporal overview immediately to the user, thereby eliminating the time-consuming manual selection process while maintaining complete information display
Solution Approach 2:
The system transitions from displaying traffic information for a single selected time point to simultaneously displaying information across multiple time dimensions. By determining estimated times of passing for multiple road segments and displaying predictive traffic information for each time point, the system creates a multi-temporal view that provides comprehensive overview without requiring users to scroll through time sequentially
2Loss of information
If predictive traffic information is displayed for multiple future points in time to provide comprehensive overview, then information completeness is improved, but driver safety deteriorates due to distraction
Solution Approach 1:
The navigation device performs automatic determination of multiple future time points and retrieves predictive traffic information without requiring continuous user interaction. The system serves itself by autonomously calculating estimated times of passing, selecting appropriate future time points, and displaying comprehensive traffic information, thereby providing complete overview while minimizing the cognitive load and distraction imposed on the driver
3Measurement precision
If detailed predictive traffic information is displayed for each road segment to improve information accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system segments the road network into multiple discrete road segments and determines estimated times of passing for each segment individually. By dividing the overall navigation task into segment-specific calculations, the system achieves precise timing information for multiple future time points while managing computational complexity through modular processing of each road segment separately
