Wrong-Way Driving Detection via Stop Line and Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems are often unable to reliably detect wrong-way driving in time, as they provide information too late for vehicles already traveling opposite the prescribed direction, leading to accidents and material damage.
Innovation Solution
A method using vehicle sensors, such as inertial and video sensors, combined with GPS and navigation data, to detect and recognize entry into a traffic lane opposite the driving direction by identifying stop lines, traffic light signals, and kinematic data, allowing for early detection and correction of wrong-way driving through acoustic, haptic, and visual alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation devices are used to detect wrong-way driving, then detection capability is provided, but detection timing is too late (vehicles already traveling opposite direction)
Solution Approach 1:
The system performs preliminary detection of wrong-way driving by analyzing stop line crossing and traffic light position relationships before the vehicle fully enters the wrong lane, enabling early warning and correction
2Reliability
If multiple detection criteria (stop line, traffic light, kinematic data) are used, then detection reliability is improved, but system complexity increases
Solution Approach 1:
The system merges multiple existing vehicle sensors (acceleration sensors, yaw rate sensors, steering angle sensors, GPS modules, video sensors) into a unified wrong-way driving detection system, achieving high reliability without adding significant complexity
Solution Approach 2:
Existing multi-functional sensors are utilized for multiple purposes: inertial sensors serve both stability control and wrong-way detection, GPS serves navigation and position verification, video sensors serve both monitoring and stop line detection

AI summary
In a method for recognizing an entry of a motor vehicle into a traffic lane of a road opposite a driving direction of the traffic lane, a stop line of the traffic lane is detected and a wrong driving direction of the motor vehicle is recognized if the motor vehicle has crossed the stop line upon entry into the traffic lane.
