Wrong-Way Ramp Detection Using Electromagnetic Vehicle Disable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic devices are inadequate in preventing vehicles from traveling the wrong way on highway ramps, as they lack a comprehensive and immediate solution to disable such vehicles before they can cause accidents.
Innovation Solution
A traffic control assembly comprising motion sensors spaced along a highway ramp, a control unit that communicates with these sensors to detect and escalate alerts, and a disabling unit that broadcasts an intense burst of electromagnetic energy to shut down the vehicle's electrical system when it attempts to travel the wrong way, combined with visual and auditory alerts to warn the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion sensors and disabling units are installed to prevent wrong-way traffic, then safety is improved, but device complexity increases
Solution Approach 1:
The system divides the ramp into multiple zones with sensors spaced at intervals, creating modular detection segments. This segmentation allows the system to cover the entire ramp length while maintaining manageable complexity through standardized sensor units and zones.
Solution Approach 2:
The system performs preliminary detection and warning actions before the vehicle reaches dangerous positions. Motion sensors detect wrong-way traffic early, and the control unit sequences alerts (visual then auditory) to give drivers multiple opportunities to correct their course before disabling action is taken.
2Measurement precision
If multiple motion sensors are distributed along the ramp, then detection capability is improved, but device complexity increases
Solution Approach 1:
The ramp is divided into multiple detection zones with sensors spaced at intervals, creating modular detection segments. This segmentation allows the system to cover the entire ramp length while maintaining manageable complexity through standardized sensor units and zones.
Solution Approach 2:
The control unit serves multiple functions: it receives signals from all motion sensors, determines wrong-way traffic conditions, sequences the alert system (visual then auditory), and controls the disabling unit. This multi-functionality reduces the need for separate control devices for each sensor.
3Reliability
If sequential alerts are provided before disabling the vehicle, then safety is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary detection and warning actions before the vehicle reaches dangerous positions. Motion sensors detect wrong-way traffic early, and the control unit sequences alerts (visual then auditory) to give drivers multiple opportunities to correct their course before disabling action is taken.
Solution Approach 2:
The alert system operates in periodic stages: first visual alerts are activated, then if the driver does not respond, auditory alerts are activated, and finally the disabling unit is engaged. This staged periodic action provides sufficient warning while maintaining rapid response capability.

AI summary
A traffic control assembly includes a plurality of motion sensors that is each positioned adjacent to a ramp of a highway. The motion sensors are spaced apart from each other and re distributed along a full length of the ramp. A control unit is in communication with each of the motion sensors and the control unit receives a plurality of inputs of sequentially increasing urgency when the motions sensors senses traffic moving the wrong way on the ramp. A disabling unit is positioned adjacent to the ramp of the highway and the disabling unit is in communication with the control unit. The disabling unit broadcasts an intense burst of electromagnetic energy when the disabling unit is turned on to disable the electrical system of a vehicle traveling the wrong way on the ramp.
