Dynamic Traffic Lane Redirection System for Accident Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traffic congestion frequently occurs due to accidents, as drivers often wait at the scene until police arrive, causing prolonged congestion on the affected road segment.
Innovation Solution
A system comprising a server and traffic redirection devices along the road that adjust lanes dynamically to bypass the congestion area, using light sources or projection lamps to guide vehicles around the incident, based on real-time congestion data and traffic patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers wait at the scene until police arrive to handle the traffic accident, then the traffic accident can be properly handled, but the traffic congestion on the road segment worsens
Solution Approach 1:
The system performs preliminary actions by automatically detecting traffic accidents through sensors and cameras, then pre-adjusts traffic lanes and redirects vehicles before police arrive. This allows accident handling to proceed reliably while maintaining traffic flow, as the system has already prepared alternative routes and lane configurations in advance
Solution Approach 2:
The patent introduces an intelligent traffic control system as an intermediary between the traffic accident and the drivers. This mediator automatically detects accidents, calculates optimal lane adjustments, and guides vehicles through alternative routes, thereby maintaining traffic flow without requiring drivers to wait at the scene
2Productivity
If traffic lanes are manually adjusted by police at the accident scene, then the congestion can be relieved, but the time required for lane adjustment increases
Solution Approach 1:
The patent replaces the mechanical system of manual lane adjustment by police with an automated intelligent control system. Sensors, cameras, and control devices work together to automatically detect accidents, calculate optimal lane configurations, and adjust traffic flow without human intervention, thereby eliminating the time delay associated with manual adjustments
Solution Approach 2:
The system dynamically changes traffic parameters such as lane configurations, signal timings, and route recommendations in real-time based on accident detection. This allows instantaneous adaptation to changing traffic conditions, reducing the time required for lane adjustment from minutes to seconds
3Adaptability or versatility
If more traffic redirection devices are deployed along the road, then the traffic redirection coverage improves, but the system complexity increases
Solution Approach 1:
The patent designs traffic redirection devices with multi-functionality, where each device can perform multiple tasks such as detecting accidents, displaying lane adjustments, and communicating with the central control system. This universal design allows comprehensive traffic coverage without proportionally increasing system complexity, as each device serves multiple purposes
Data Source
AI summary
The present disclosure provides a system and a method for traffic redirection upon congestion occurring on a road. The system for redirecting traffic on a road comprises a server and at least one traffic redirection device. Each of the at least one traffic redirection device is disposed along the road and is coupled with the server. The server is configured to receive congestion site information if a congestion occurs on the road, to determine a separation zone covering a location of congestion based on the congestion site information, to determine a redirected traffic pattern, and to send a traffic redirection instruction to the at least one traffic redirection device. The at least one traffic redirection device is configured to respond to the traffic redirection instruction, such that the at least one traffic redirection device together displays the redirected traffic pattern on the road to thereby guide vehicles to bypass the separation zone.
