Composite Road Module for Conflict-Free Traffic Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Urban traffic congestion is exacerbated by conflicts at planar intersections, which traditional solutions like interchanges cannot fully address due to space constraints and inefficiencies in traffic flow management.
Innovation Solution
Implementing a composite road module with two roads, one following left-hand traffic rules and the other right-hand traffic rules, connected by intercommunication passages that allow vehicles to change types and routes seamlessly, eliminating conflict points and reducing the need for traffic lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fully functional interchange is built at each intersection to eliminate conflict points, then traffic flow efficiency is improved, but the area occupied and construction cost increase extremely
Solution Approach 1:
The road system is segmented into multiple lanes with different driving rules (left-hand traffic lanes and right-hand traffic lanes) that run parallel to each other. This segmentation allows different traffic flows to be separated into distinct segments, eliminating conflict points without requiring a complete interchange structure at each intersection.
Solution Approach 2:
The patent introduces a new dimension to traffic organization by creating parallel road layers with opposite driving rules. Instead of using vertical interchanges to resolve conflicts, the solution uses horizontal parallel lanes with alternating left-hand and right-hand traffic rules, effectively adding a lateral dimension to traffic flow separation.
2Area of stationary object
If traditional planar intersections are maintained to save space, then area occupation is reduced, but traffic congestion increases due to conflict points and signal lamps
Solution Approach 1:
The planar intersection is segmented into multiple parallel lanes with alternating driving rules. By dividing the road into left-hand traffic lanes and right-hand traffic lanes that run parallel, the patent eliminates conflict points while maintaining a compact planar structure, avoiding the need for large interchange constructions.
Solution Approach 2:
The patent introduces dynamic lane assignment where vehicles are directed to different parallel lanes based on their destination and traffic flow patterns. This dynamic organization allows the system to adapt to varying traffic conditions and eliminate conflicts without requiring physical interchanges.
3Reliability
If signal lamps are used at planar intersections to manage traffic flows, then traffic safety is improved, but waiting time and traffic efficiency deteriorate
Solution Approach 1:
The patent extracts and removes the need for signal lamps by eliminating conflict points through parallel lanes with alternating driving rules. By taking out the signal control mechanism entirely, the system eliminates waiting time while maintaining safety through the inherent separation of conflicting traffic flows.
Solution Approach 2:
The road system itself provides safety through its structure - parallel lanes with alternating left-hand and right-hand traffic rules automatically prevent conflicts without requiring external signal control. The system serves its own safety function through its geometric design rather than requiring additional signal infrastructure.
