Adaptive Traffic Control System for Network Congestion Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic management systems fail to efficiently mitigate traffic congestion by not considering the overall impact of individual vehicle routes on the entire road network, often leading to increased congestion and inefficiencies due to lack of adaptive and dynamic traffic control measures.
Innovation Solution
A processor-based system that receives traffic reports, determines mitigation strategies, and sends control instructions for temporary traffic controls to minimize congestion across a road network by dynamically adjusting traffic signals, tolls, and incentives, considering the impact on the entire network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fixed traffic signals are added to mitigate traffic congestion, then traffic flow at certain times is improved, but new traffic congestion is created at other times and locations
Solution Approach 1:
The patent implements dynamic traffic control by enabling traffic signals to adapt their operation in real-time based on actual traffic conditions. The system continuously monitors traffic flow data and adjusts signal timing and phase configurations dynamically, transforming static traffic control infrastructure into a responsive system that can prevent congestion redistribution across the network.
Solution Approach 2:
The system incorporates feedback mechanisms by continuously collecting traffic data from sensors and cameras, analyzing current congestion patterns, and using this information to adjust traffic signal operations. This closed-loop control enables the system to learn from past performance and optimize signal timing to avoid creating new congestion hotspots while maintaining improved flow at previously congested locations.
2Productivity
If road network is widened or additional arteries are added to accommodate population growth, then traffic capacity is increased, but implementation cost and complexity increase significantly
Solution Approach 1:
The patent changes operational parameters of existing traffic infrastructure rather than physical infrastructure itself. By adjusting traffic signal timing, phase sequences, and coordination patterns, the system effectively increases traffic capacity through software-based optimization, avoiding the need for expensive road widening or new artery construction while achieving comparable or superior results.
Solution Approach 2:
The intelligent traffic control system serves multiple functions simultaneously: it optimizes traffic flow, reduces congestion, lowers emissions, and adapts to various traffic patterns throughout the day. This multi-functionality allows existing infrastructure to handle increased population-generated traffic without requiring additional physical expansion, making the system universally applicable to diverse urban environments.
3Loss of time
If individual vehicle routes are optimized without considering overall network impact, then travel time for individual vehicles is reduced, but overall network congestion increases
Solution Approach 1:
The patent merges individual route optimization with network-wide congestion management by integrating real-time traffic data from across the entire network into the routing algorithm. The system combines local travel time considerations with global congestion patterns to generate routes that optimize individual vehicle travel while simultaneously maintaining overall network efficiency, preventing the redistribution of congestion to other areas.

AI summary
A system includes a processor configured to receive a plurality of traffic reports corresponding to individual road segments of an interconnected road network of road segments. The processor is also configured to determine a mitigation strategy, utilizing one or more temporary traffic controls existing for the individual road segments, designed to minimize overall traffic congestion on the road network and send control instructions for the one or more temporary traffic controls, instructing control in accordance with the determined mitigation strategy.
