Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vehicle transportation network information sources are used, then the system is simple to operate, but the information is missing, incomplete, or inaccurate
Solution Approach 1:
The patent combines multiple information sources including remote vehicle messages, host vehicle sensors, and map data into a unified projected network information system. This merging of diverse data streams resolves the contradiction by improving information completeness and accuracy while managing complexity through integrated processing.
Solution Approach 2:
The system performs preliminary actions by generating projected network information in advance before the host vehicle reaches intersections or network segments. This proactive generation of network information improves reliability by ensuring data availability while reducing real-time processing complexity.
2Loss of information
If projected network information is generated using multiple data sources, then the information completeness improves, but the processing time increases
Solution Approach 1:
The system generates projected network information in advance before the host vehicle reaches intersections or network segments. This preliminary generation approach ensures complete information is available while reducing real-time processing requirements, thus resolving the contradiction between information completeness and processing time.
Solution Approach 2:
The patent segments the network information processing into discrete components such as intersection projections, lane level details, and congestion assessments. This segmentation allows parallel processing of different information elements, improving completeness while managing processing time through efficient task distribution.
3Measurement precision
If detailed lane level information is provided at intersections, then the navigation precision improves, but the data transmission requirements increase
Solution Approach 1:
The patent applies local quality by providing detailed lane level projected network information specifically at intersections and relevant network segments, while using less detailed representations elsewhere. This targeted approach improves navigation precision where needed while reducing overall data transmission requirements.

AI summary
A method and apparatus for projected vehicle transportation network information notification for use in traversing a vehicle transportation network may include receiving a remote vehicle message including remote vehicle information indicating remote vehicle geospatial state information and remote vehicle kinematic state information, identifying host vehicle information including host vehicle geospatial state information and host vehicle kinematic state information, generating projected vehicle transportation network information representing a portion of the vehicle transportation network based on the remote vehicle information and the host vehicle information, and traversing the intersection represented by the projected vehicle transportation network information using the projected vehicle transportation network information by outputting at least a portion of the projected vehicle transportation network information representing the vehicle transportation network intersection.
