The KTI KTI16022900CR30 300 mm Red Cross and Green Arrow Traffic Light is engineered for clear optical lane status management across transport infrastructure, industrial facilities, and automated access control environments. Featuring dual visual signaling in a unified 300 mm optical aperture, the unit delivers high-visibility 400 cd luminous output at 625 nm (Red Cross) and 500 nm (Green Arrow) to regulate vehicular movement efficiently.
Toll Plaza Overhead Lane Signalling (OHLS)
In highway toll plaza automation, clear lane-state communication is critical for driver guidance and safety. The KTI16022900CR30 is designed for canopy and overhead gantry installation directly above toll booths and electronic toll collection (ETC) lanes. The 625 nm Red Cross clearly communicates closed lanes, maintenance bays, or emergency stops, while the 500 nm Green Arrow indicates active, open passage. Operating on 12V DC or 24V DC power inputs with a 11 W to 12 W power draw, the light interfaces directly with standard toll lane controllers and remote relay modules. Its IP65-rated UV-stabilized polycarbonate housing withstands highway soot, wind-driven rain, and continuous solar exposure.
Industrial Gate and Weighbridge Traffic Management
Industrial logistics terminals, manufacturing plants, and heavy-duty weighbridges require precise single-vehicle indexing. The KTI 300 mm signal integrates with programmable logic controllers (PLCs), optical vehicle sensors, and automated barrier systems to coordinate traffic flow over weight scales and inspection bays:
- Weighbridge Ingress/Egress: Signals drivers to pull onto the platform (Green Arrow) and halt during stabilization/measurement (Red Cross).
- Automated Factory Gates: Coordinates with RFID readers and automatic boom barriers, holding approaching trucks until credentials are authenticated.
- Low-Impact Mounting: With a physical dimension of 310 mm x 310 mm x 100 mm and a weight under 2 kg, the unit mounts onto structural stanchions, weighbridge booths, or wall brackets without requiring heavy structural reinforcement.
Automated Parking Management and Multi-Level Garages
Commercial parking structures, logistics depots, and corporate campuses utilize the KTI single-aspect unit to optimize tidal flow, ramp access, and lane assignment. The combined Cross/Arrow display saves overhead space compared to conventional multi-head traffic lights while providing 400 cd luminance for unambiguous readability at ramp entrances, one-way bottlenecks, and ticket-dispensing lanes.
Security Checkpoints and Critical Infrastructure Lanes
Government facilities, port terminals, and border checkpoints require dependable lane-use signalling to enforce access protocol. The IP65 dust-tight and water-jet-resistant build ensures continuous outdoor operation, while dual 12V/24V DC compatibility simplifies battery-backed or solar-supplemented field security installations.
