Virtual Lane Map Control for Uneven Two-Way Driveway Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing virtual lanes on one-way roads fail to fully utilize the road capacity when the inbound and outbound vehicle traffic volumes significantly differ, leading to underutilization of lanes in the direction with fewer vehicles.
Innovation Solution
A virtual map providing device that dynamically adjusts inbound and outbound zones on a driveway based on traffic conditions and timeframes, changing lane configurations and speed limits to optimize traffic flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of virtual lanes is changed depending on timeframe, then the road utilization is improved, but the road capacity cannot be fully utilized when inbound and outbound traffic volumes are completely different
Solution Approach 1:
The patent implements dynamic virtual lane allocation by continuously adjusting the number of virtual lanes in inbound and outbound directions based on real-time traffic volume. The system changes lane configurations dynamically rather than using fixed timeframe-based settings, allowing the road capacity to be fully utilized regardless of whether inbound or outbound traffic is heavier.
Solution Approach 2:
The system changes the parameter of virtual lane number based on traffic volume conditions. When traffic volume in one direction exceeds a threshold, the system increases virtual lanes in that direction and decreases them in the opposite direction, optimizing road utilization for current traffic patterns.
2Device complexity
If fixed virtual lanes are set for one-way road, then the system complexity is reduced, but the road cannot be fully utilized when traffic distribution is uneven
Solution Approach 1:
The patent transforms the static virtual lane configuration into a dynamic system that automatically adjusts lane numbers based on real-time traffic conditions. This dynamic approach maintains relatively simple system architecture while achieving high road utilization through automated, condition-based lane allocation.

AI summary
A virtual map providing device (100) dynamically changes, with respect to a driveway (201) on which one or more inbound vehicles (210) moving in an inbound direction and one or more outbound vehicles (210) moving in an outbound direction are to move, an inbound zone on which the one or more inbound vehicles are to move, and an outbound zone on which the one or more outbound vehicles are to move. Then, the virtual map providing device delivers change information data including information of a post-change inbound zone and information of a post-change outbound zone.
