Vehicle Wrong-Way Entry Prevention on One-Way Roads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation systems lack effective measures to prevent vehicles from entering one-way roads in the wrong direction, leading to potential collisions and traffic jams, as they often rely on human judgment which can be erroneous or absent in autonomous vehicles.
Innovation Solution
Implementing sensors and computer systems in vehicles to detect approaching one-way roads and notify occupants, and if necessary, slow down or prevent entry to ensure safe navigation, utilizing a combination of radar, sonar, and optical sensors to assess speed, position, and direction, and potentially alerting first responders if no response is received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles rely on human judgment to determine road direction, then operational simplicity is maintained, but safety deteriorates due to human error or absence in autonomous vehicles
Solution Approach 1:
The vehicle system performs self-monitoring of its own position and direction relative to one-way roads using onboard sensors and computer systems, eliminating the need for external human judgment while maintaining autonomous operation
Solution Approach 2:
The patent replaces human judgment (biological system) with sensor-based detection and computer processing (electronic system) to determine road direction and prevent wrong-way entry, thereby improving reliability through consistent automated operation
2Ease of operation
If vehicles are allowed to enter one-way roads without prevention, then freedom of movement is maintained, but harmful effects increase due to collisions and traffic jams
Solution Approach 1:
The system applies preliminary countermeasures by detecting approaching one-way roads in advance and notifying occupants before entry, and if necessary, slowing down to prevent entry, thereby preventing harmful collisions and traffic jams before they occur
Solution Approach 2:
The system provides feedback to vehicle occupants through notifications about approaching one-way roads, allowing drivers to make informed decisions while maintaining safety through automated monitoring and intervention when necessary
3Reliability
If automated systems slow down vehicles to prevent wrong-way entry, then safety is improved, but productivity decreases due to reduced traffic flow
Solution Approach 1:
The system applies partial action by only slowing down or preventing entry when actual wrong-way approach to one-way roads is detected, rather than imposing continuous restrictions, thereby maintaining safety while minimizing impact on overall traffic flow efficiency

AI summary
An example operation includes one or more of initially determining, via one or more sensors on a transport, that the transport is approaching a one-way road in a wrong direction based on a slowing down of the transport and a movement of the transport toward the one-way road, notifying, via the one or more sensors, one or more occupants of the transport about the approaching, and in response to the transport continuing to approach in the wrong direction, slowing the transport, by a computer associated with the transport, to not permit entry into the one-way road.
