Wrong-Way Detection System with Preliminary Communication Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting and warning other road users about wrong-way drivers are time-consuming, allowing little to no time for effective warning before a potential collision, as they require confirmation of wrong-way driving before establishing communication.
Innovation Solution
The method involves pre-detecting the potential for wrong-way driving and establishing communication before confirmation, using a combination of vehicle position and movement trajectory data with digital maps and inertial sensors, allowing for early warning via already established communication links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication is established only after confirmation of wrong-way driving, then false warnings are avoided, but warning time is insufficient for effective collision prevention
Solution Approach 1:
The system performs preliminary actions by establishing communication links with potentially affected road users before wrong-way driving is fully confirmed. When a vehicle shows indicators of wrong-way driving (such as trajectory analysis suggesting wrong direction), the system proactively sets up communication channels with other road users in the area, so that warnings can be immediately transmitted once confirmation is achieved, eliminating the time delay that would otherwise exist.
2Measurement precision
If detection methods require multiple confirmation steps, then detection accuracy improves, but the time from detection to warning increases
Solution Approach 1:
The system performs preliminary detection and analysis of vehicle trajectories to identify potential wrong-way driving situations before full confirmation is obtained. This allows the system to prepare warning messages and establish communication channels in advance, so that when multiple confirmation steps validate the wrong-way driving, the warning can be issued immediately without delay.
3Loss of energy
If the system waits for certain detection before establishing communication, then communication resources are conserved, but critical warning time is lost
Solution Approach 1:
The system performs preliminary assessment of wrong-way driving potential based on initial detection data and establishes communication links proactively when risk is identified, rather than waiting for complete confirmation. This preliminary action ensures that communication channels are ready when needed, balancing resource consumption with the critical need for timely warnings.

AI summary
The invention relates to a method (300) for warning (310) other road users (204) when a vehicle (102) is travelling the wrong way on a motorway or dual carriageway, wherein the method (300) has a step (301) of preliminary detection, a step (306) of set-up, a step (304) of detection and a step (310) of provision. In step (301) of preliminary detection, a wrong-way travel potential for possible wrong-way travel by the vehicle (102) is detected in a preliminary fashion. In step (306) of set-up, a communication link (200) to at least one road user (204) that is at risk from the wrong-way travel is set up if the wrong-way travel potential is greater than a preliminary warning value. In step (304) of detection, the wrong-way travel by the vehicle (102) is detected. In step (310) of provision, a piece of wrong-way driver information is provided for the road users (204) at risk via the communication link (200) that has been set up if the possible wrong-way travel is detected as actual wrong-way travel.
