Wrong-Way Vehicle Detection via Multi-Vehicle Behavior Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrong-way vehicle detection systems fail to accurately identify wrong-way vehicles when they cannot communicate with a server.
Innovation Solution
A wrong-way vehicle determination device that receives and analyzes vehicle behavior information to determine the presence of a wrong-way vehicle based on abrupt changes in behavior, using a server to collect and process data from multiple vehicles to estimate the trajectory and speed of the vehicle, allowing for detection even if the wrong-way vehicle cannot communicate directly with the server.

Engineering Contradiction Analysis
1Measurement precision
If the wrong-way vehicle is required to communicate with the server for detection, then the detection accuracy is improved, but the detection capability deteriorates when the wrong-way vehicle cannot communicate with the server
Solution Approach 1:
The patent introduces other vehicles as intermediaries to detect the wrong-way vehicle. When a wrong-way vehicle cannot communicate directly with the server, nearby vehicles that can communicate serve as mediators. These vehicles detect the wrong-way vehicle's presence through its impact on their own behavior (abnormal braking, steering, etc.) and relay this information to the server, enabling indirect detection of the wrong-way vehicle.
Solution Approach 2:
Instead of detecting the wrong-way vehicle directly through its own communication, the system inverts the detection approach by detecting the wrong-way vehicle through its effects on other vehicles. The detection is performed by vehicles that are targets of the wrong-way vehicle's influence, rather than by the wrong-way vehicle itself.
2Measurement precision
If vehicle behavior information from multiple vehicles is collected and analyzed, then the wrong-way vehicle detection accuracy is improved, but the system complexity increases
Solution Approach 1:
Each vehicle in the system performs self-service by monitoring its own behavior and automatically detecting abnormalities. Vehicles independently analyze their own driving patterns (braking, steering, acceleration) and self-identify when their behavior becomes abnormal, eliminating the need for complex external monitoring systems and reducing overall system complexity.
Solution Approach 2:
The system uses universal vehicle sensors and communication devices that serve multiple functions: normal driving operation, self-monitoring of vehicle behavior, detection of wrong-way vehicles, and communication with the server. This multi-functionality reduces the need for dedicated detection hardware and simplifies the overall system architecture.

AI summary
The wrong-way vehicle determination device includes a reception unit and a determination unit. The reception unit receives a plurality of pieces of vehicle behavior information corresponding to each of the plurality of vehicles and indicating vehicle behaviors and positions at which the vehicle behaviors occur. The determination unit determines whether there is a wrong-way vehicle based on a position at which a sudden vehicle behavior occurs based on a plurality of pieces of vehicle behavior information.
