Background:
Fujian Province, with its dense urban road networks and high-traffic highways, required a reliable and high-performance traffic data collection system to enhance traffic management, optimize signal control, and support intelligent transportation systems (ITS). The ClairLup-V8F 8-channel loop detector was deployed across key locations, including urban intersections, expressways, and tunnels, to provide real-time, accurate traffic flow statistics.

Key Applications and Benefits:

1. Multi-Lane Traffic Flow Monitoring
   • The ClairLup-V8F’s 8-channel loop connectivity enabled simultaneous detection across 4 lanes, capturing critical parameters such as vehicle count, occupancy, speed, headway time, and following vehicle percentage. This granular data helped traffic authorities analyze congestion patterns and adjust signal timings dynamically.
2. High-Speed, High-Accuracy Detection
   • With a response time of <3ms, the system ensured real-time vehicle detection, even in high-speed scenarios like Fujian’s expressways. The hardware-based FPGA algorithm guaranteed interference resistance and measurement precision, critical for enforcement systems (e.g., speeding detection) and security checkpoints.
3. Intelligent Adaptive Features
   • The detector’s background frequency auto-update tracked environmental changes (e.g., temperature, loop degradation), maintaining accuracy over time. Its anti-lock algorithm prevented data loss due to loop abnormal performance, reducing maintenance needs.
4. Enhanced Diagnostics and Visualization
   • Real-time vehicle waveform displays allowed engineers to visually verify loop performance and diagnose installation issues (e.g., improper sealing, cable faults). The system’s loop fault detection (open/short circuit alerts) enabled rapid troubleshooting, minimizing downtime.

Outcome:
By integrating the ClairLup-V8F, Fujian’s traffic management centers gained a scalable, maintenance-free solution for 24/7 data collection. The system’s multi-parameter output supported advanced analytics, while its robust hardware design ensured reliability in diverse road conditions—from urban intersections to mountainous tunnels. This deployment underscored the detector’s role as a cornerstone of modern ITS infrastructure.
