Predictive Traffic Management Instructions for Secondary Roadway Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to effectively manage traffic after a first conflict event, leading to the prediction and potential occurrence of a second conflict due to vehicles reacting simultaneously to resolve the first conflict, which can compromise safety and efficiency on roadways.
Innovation Solution
A system that utilizes anomaly detection to identify abnormal driving behaviors and provides tailored traffic management instructions to vehicles, considering their reactions to the first conflict, to prevent a second conflict by optimizing vehicle operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If vehicles react simultaneously to resolve the first conflict, then the response time is reduced, but a second conflict occurs due to interdependent reactions
Solution Approach 1:
The system performs preliminary action by predicting the second conflict before it occurs. The traffic management system analyzes the reactions of vehicles to the first conflict, identifies patterns that could lead to a second conflict, and generates preventive instructions before the second conflict actually happens. This allows vehicles to adjust their operations in advance, avoiding the simultaneous reactions that would cause the second conflict while maintaining fast response to the first conflict.
2Reliability
If vehicles are instructed to change operations after the first conflict, then safety is improved, but traffic efficiency decreases due to additional control instructions
Solution Approach 1:
The system implements feedback by continuously monitoring vehicle reactions to the first conflict instruction and using this information to generate the second instruction. The traffic management system collects data on how vehicles responded to the initial conflict, analyzes these reactions, and adjusts subsequent instructions accordingly. This feedback loop ensures that safety instructions are optimized based on actual vehicle behavior, preventing unnecessary control actions that would reduce traffic efficiency while maintaining safety.

AI summary
Systems and methods are provided for programmatically determining traffic management operations in response to conflicts on a roadway. For example, the systems and methods may determine a first traffic management instruction for a first vehicle for a first conflict on a roadway; access characteristics of the first vehicle associated with the first management instruction in response to the first conflict; determine a second conflict occurring after and connected to the first conflict; using the characteristics of the first vehicle, determine a second traffic management instruction for the first vehicle for the second conflict; and provide the second traffic management instruction to the first vehicle.
