Gantry Detection for Early Wrong-Way Driver Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting wrong-way drivers on highways are often too late, as they rely solely on navigation systems and sensors, failing to recognize the risk early enough to prevent collisions, especially at high speeds on freeways where accidents can be fatal.
Innovation Solution
A method and device that detect a motor vehicle's passage through a road-sign gantry by receiving environmental information, recognizing road signs, determining position data, and calculating distances to identify when a vehicle is within or approaching the gantry, using video data from cameras and inertial sensors to verify wrong-way travel.

Engineering Contradiction Analysis
1Reliability
If navigation systems and sensors are used to detect wrong-way drivers, then detection capability is provided, but detection timing is too late to prevent collisions
Solution Approach 1:
The system performs preliminary detection by monitoring passage through road-sign gantries before the vehicle actually enters the wrong-way freeway section. This early detection at the gantry allows sufficient time to alert the driver and take preventive measures before the dangerous situation develops
Solution Approach 2:
The road-sign gantry serves as an intermediary detection point between the junction and the freeway. By using the gantry as a mediator, the system can detect wrong-way travel intent earlier than direct freeway entry detection, providing a warning buffer zone
2Measurement precision
If multiple sensors and navigation systems are integrated, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The system extracts and utilizes existing sensors already present in modern vehicles (acceleration sensors, steering-angle sensors, navigation systems, video sensors) rather than adding a completely new detection system. This approach maintains detection accuracy while avoiding excessive complexity by leveraging available components
Solution Approach 2:
The system makes existing multi-functional sensors serve the additional function of wrong-way travel detection. For example, navigation systems originally for routing now also detect gantry passage, and video sensors originally for general monitoring now specifically identify road signs and gantries

AI summary
The disclosure relates to a method for detecting the passing of a motor vehicle through a road sign gantry, having the steps: receiving information on the surroundings, detecting road signs in the information on the surroundings, selecting a first road sign and a second road sign which together form a road sign gantry, acquiring position data for the first road sign and for the second road sign from the information on the surroundings, determining a gantry width between the first road sign and the second road sign, determining a first distance of the motor vehicle from the first road sign, determining a second distance of the motor vehicle from the second road sign, and detecting the passing through of the vehicle as a function of the gantry width, the first distance and the second distance.
