Single-Track Roadway Passage Control Using Speed Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Narrow roadways pose challenges for vehicle passage, particularly in rural areas and wintry conditions, where visibility is restricted and reversing is uncomfortable and time-consuming, especially for larger vehicles.
Innovation Solution
A method and system that detect and analyze roadway sections ahead, calculate vehicle travel times, and adjust speeds to avoid collisions by transmitting data through networks, allowing vehicles to navigate narrow sections safely and efficiently by optimizing passage through bottlenecks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles drive through narrow roadway sections without coordination, then individual vehicles can maintain their speed, but the risk of collision and forced reversing increases
Solution Approach 1:
The system performs preliminary detection of narrow roadway sections and calculates passage times before vehicles reach the bottleneck. By determining the time required to traverse the narrow section in advance and communicating this to other vehicles, the system enables coordinated passage planning that prevents collisions while optimizing travel time through the bottleneck.
Solution Approach 2:
The system establishes continuous communication between vehicles through a network, where each vehicle transmits its identity, position, and calculated passage time data. Other vehicles receive this information and use it to determine their own speeds and passage timing, creating a feedback loop that coordinates movement through the narrow section and eliminates the need for forced reversing.
2Reliability
If vehicles reverse to allow oncoming traffic to pass, then collision risk is reduced, but time consumption and discomfort increase
Solution Approach 1:
The system calculates and communicates passage time data before vehicles reach the narrow roadway section, enabling advance coordination of passage sequences. This preliminary planning allows vehicles to maintain forward motion and pass through bottlenecks in an organized sequence without needing to reverse, thereby reducing time loss while ensuring safe passage.
3Productivity
If vehicles increase speed to reduce travel time through narrow sections, then productivity improves, but the risk of collision with oncoming vehicles increases
Solution Approach 1:
The system uses network communication to share real-time data about vehicle positions, speeds, and calculated passage times through narrow sections. Each vehicle receives feedback from others and adjusts its speed accordingly, enabling maintained or increased productivity while ensuring that no two vehicles occupy the narrow section simultaneously, thus eliminating collision risk.
