Bypass Merge Lane Navigation for Autonomous Highway Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traffic congestion and safety risks are exacerbated by vehicles entering and exiting roadways, particularly in the vicinity of entrances and exits, which is compounded by the introduction of autonomous vehicles, necessitating improved traffic management systems.
Innovation Solution
Implementing lane separators and signage to manage traffic flow, combined with data acquisition and navigation systems for autonomous vehicles to navigate these separators, ensuring safe merging and exiting through bypass lanes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles enter and exit the roadway at entrances and exits, then access to the roadway is provided, but traffic congestion and safety risks increase in the vicinity
Solution Approach 1:
The roadway is segmented into through lanes and merge lanes using lane separators. Through lanes are dedicated to continuous traffic flow while merge lanes handle entering/exiting vehicles, separating conflicting traffic patterns and eliminating congestion and safety risks in the vicinity of entrances and exits
Solution Approach 2:
The merge function is extracted from the through lanes and placed into dedicated merge lanes. This removes the harmful interaction between through traffic and merging traffic, allowing through traffic to proceed without interruption while providing controlled access points for entering and exiting vehicles
2Productivity
If motorists change lanes in the vicinity of an entrance or exit to avoid congested traffic, then traffic flow is improved, but safety risk increases
Solution Approach 1:
By segmenting the roadway into through lanes and merge lanes with physical or visual lane separators, the system eliminates the need for lane changes in congested areas. Through traffic remains in dedicated lanes while merge traffic uses separate lanes, maintaining productivity without increasing safety risks
Solution Approach 2:
Lane separators act as intermediaries that guide traffic flow without requiring vehicles to change lanes. The separators provide clear directional guidance, allowing traffic to move efficiently through the roadway while eliminating unsafe lane-changing maneuvers in the vicinity of entrances and exits
3Object-affected harmful factors
If lane separators are implemented to manage traffic flow, then traffic safety and congestion are reduced, but device complexity increases
Solution Approach 1:
The roadway infrastructure is segmented into functional zones using lane separators that are simple in design but effective in separating traffic flows. This segmentation approach improves safety and reduces congestion while maintaining relatively simple infrastructure that integrates with existing roadway designs
Solution Approach 2:
Lane separators are implemented locally at specific locations where entrances and exits create traffic conflicts, rather than throughout the entire roadway. This localized approach addresses safety and congestion issues at critical points while minimizing overall infrastructure complexity and cost

AI summary
A system to improve the management of through traffic including an autonomous vehicle and other vehicles entering and exiting a multilane roadway. The lanes are separated by at least one lane separator which should not be crossed by traffic along a designated portion of the roadway, such as within a predetermined distance from a roadway entrance or exit. The at least one lane separator may be any lane marking, barrier, or the like. The at least one lane separator can be any length and located at any relative position with respect to the lanes.
