The Unified Intelligent Traffic Signal Control Platform is an integrated solution tailored for modern urban traffic governance. It adopts a “Central Coordination + Edge Intelligence” system architecture, enabling real-time monitoring, intelligent signal optimization, and coordinated control across city traffic networks.

The platform seamlessly connects various traffic signal controllers and control systems using standardized protocols, enabling full-domain, intelligent signal control capabilities. It supports real-time sensing at intersections, localized optimization, regional coordination, and post-deployment evaluation to form a closed-loop, quantifiable traffic control process.

Core Functional Modules

1. Networked Signal Control

• Real-time access and management of various traffic signal controllers
• Remote configuration and plan modification
• Emergency control capabilities
• Supports unified signal networking and centralized management

2. Signal Issue Diagnosis Service

• Real-time calculation of operational indicators (traffic volume, saturation, queue length, delay, green utilization)
• Automatic identification and alerting of signal-related issues when thresholds are exceeded
• Provides insights and decision support for issue resolution and plan adjustments

3. Single Intersection Optimization

• AI-driven dynamic timing adjustment for isolated intersections
• Responsive to changing traffic flow patterns
• Reduces localized congestion, enhances green light efficiency, and minimizes delays

4. Coordinated Signal Optimization

• Synchronizes signals across corridors and regions
• Optimizes traffic flow during peak, off-peak, and nighttime periods
• Enables implementation of area-level traffic control strategies

5. Strategy Evaluation and Feedback

• Pre- and post-deployment assessment using key indicators:
  • Intersection and regional traffic efficiency index
  • Average vehicle speed
  • Intersection delay
• Supports continuous optimization through performance feedback and machine learning
