Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular communication systems rely heavily on historical data for route optimization and collision avoidance, which can lead to inaccurate warnings due to unpredictable traffic patterns and road hazards, potentially annoying operators with false alerts.
Innovation Solution
A computer-implemented method and system that combines historical data with real-time data from various sources to predict potential road hazards and collision scenarios, using a vehicular communication network to share information among vehicles and users, and modify collision warning systems based on current environmental conditions and detected vulnerable road users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If historical data alone is used to determine traffic patterns and road hazards, then route optimization can be provided, but the accuracy of warnings decreases due to unpredictable traffic patterns
Solution Approach 1:
The patent combines historical data with real-time data from multiple sources including sensors, cameras, radar, and communication networks to create a hybrid warning system. This merging allows the system to leverage both the predictive power of historical patterns and the immediacy of current conditions, thereby improving both accuracy and reliability of collision warnings.
Solution Approach 2:
The system continuously monitors current traffic conditions and compares them against historical patterns, using this feedback to adjust and refine warning predictions. Real-time data from sensors and communications provides ongoing feedback that allows the system to correct inaccuracies and adapt to changing conditions, improving the overall reliability of collision avoidance.
2Productivity
If historical data is used to predict traffic patterns, then route optimization is achieved, but false alerts increase potentially annoying operators
Solution Approach 1:
The patent introduces an intermediary data processing layer that filters and validates information from multiple sources before generating warnings. This intermediary system cross-references historical patterns with real-time conditions, acting as a mediator that prevents false alerts while maintaining route optimization benefits.
Solution Approach 2:
The system replaces purely mechanical historical data analysis with a hybrid approach that incorporates real-time sensor data, camera feeds, radar information, and communication network data. This substitution of pure historical analysis with multi-source real-time verification reduces false alerts while maintaining optimization effectiveness.
3Measurement precision
If real-time data from multiple sources is integrated, then warning accuracy improves, but device complexity increases
Solution Approach 1:
The patent segments the complex data processing system into distinct functional modules: sensor data processing, camera analysis, radar processing, communication data handling, and warning generation. This segmentation allows each component to specialize in processing specific data types, reducing overall system complexity while maintaining high warning accuracy through integrated operation.
