Efficient, seamless passage through ETC lanes

Addressing the pain points of traditional inductive loop sensors used in ETC lanes—such as road disruption during construction, difficult maintenance, high failure rates, susceptibility to interference leading to missed vehicle detections, and limited functionality that cannot be upgraded—along with the core requirements of “installation without road disruption, precise detection, stable operation and maintenance, and scalable functionality”—the ETC laser coil offers an upgrade solution.

Application Logic: Installed above the centerline of the roadway via pole mounting (height ≥ 8 meters), this system operates without damaging the road surface. It employs a high-speed laser scanner emitting at 905 nm, which is safe for human eyes, to simulate 4–8 flexibly configurable virtual coils. The system captures in real time the position and contour of dynamic traffic flows ranging from 0 to 80 km/h, outputting vehicle presence/absence signals within 50 milliseconds. It accurately identifies both following and parallel driving conditions.

Core advantages: Detection accuracy ≥ 99.9%, eliminating missed vehicles and incorrect inspections; IP67-rated protection and wide temperature tolerance from -30°C to +70°C; MTBF ≥ 50,000 hours for zero maintenance; capable of outputting vehicle length, height, and location information to enable smart applications; reduces construction time by 90% without disrupting traffic, significantly lowering operational costs.
