Wrong-Way Driving Detection Using Junction Line Traversal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wrong-way driving incidents on unidirectional roadways are difficult to detect reliably, often resulting in fatal accidents due to high collision speeds, as navigation devices provide information too late for vehicles already driving against traffic.
Innovation Solution
A method and control and detection device that detect traversing of stop lines or solid lines at junctions, collect directional information, and assess the probability of wrong-way driving incidents using sensors like video, navigation, and inertial systems, allowing for a plausibility check before entering the roadway, enhancing safety and reliability.

Engineering Contradiction Analysis
1Reliability
If navigation devices are used to detect wrong-way driving incidents, then detection capability is provided, but the detection occurs too late when vehicles are already driving against traffic
Solution Approach 1:
The system performs preliminary detection of wrong-way driving behavior at junctions before vehicles enter the unidirectional roadway. By detecting traversing of stop lines or solid lines and collecting directional information ahead of the vehicle, the system identifies potential wrong-way incidents early, allowing intervention before the vehicle is already driving against traffic on the expressway.
2Measurement precision
If multiple sensor data sources are integrated for plausibility checking, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The system merges data from multiple existing sensor sources including video sensors, navigation devices, and inertial sensors to perform plausibility checking. By combining these data sources within a unified control and detection unit, the system achieves high detection accuracy without requiring entirely new hardware, thus managing complexity while improving precision.
Solution Approach 2:
The control and detection unit performs multiple functions using the same sensor data: it detects traversing of road markings, collects directional information, determines vehicle position, and performs plausibility checking for wrong-way driving incidents. This multi-functionality reduces the need for separate specialized devices, thereby managing system complexity while maintaining high detection accuracy.

AI summary
In a method for checking the plausibility of a wrong-way driving of a motor vehicle when entering a unidirectional roadway, a traversing of a stop line or a solid line of a junction of the unidirectional roadway is detected and/or at least one item of directional information of a roadway of the junction, which is located ahead of the motor vehicle, is collected, and a probability of a wrong-way driving is ascertained based on the detection. The method is performed by a control and detection unit for checking the plausibility of a wrong-way driving.
