Lane Control Lights

A lane light is an illuminated signal head, typically using LED or fiber optic technology, mounted above a traffic lane to indicate whether that lane is open, closed, or restricted. Lane lights are commonly used in dynamic lane management systems, toll plazas, tunnels, and reversible roadway applications to guide driver behavior.

The primary function of lane use control signals is to communicate real-time lane availability to drivers, allowing traffic agencies to dynamically open, close, or reassign lanes based on traffic volume, incidents, or maintenance needs. This improves traffic flow, reduces congestion, and enhances roadway safety during variable conditions.

LED lane control signals use light-emitting diodes directly within the sign face for high brightness and low maintenance, while fiber optic signals transmit light from a remote source through optical fibers to the display. Both offer strong visibility, but fiber optic and hybrid Fiber/LED designs are often chosen for blank-out sign applications requiring uniform illumination.

Lane control signal systems and their supporting controllers typically must meet NEMA TS1 and TS2 specifications, Advanced Transportation Controller (ATC) standards, and state-specific requirements such as Caltrans TEES 2020. Compliance ensures interoperability with existing traffic cabinets and consistent performance across signalized corridors.

Yes, most lane control light systems are designed to integrate with ATC-compliant controllers such as the 2070 Series, which run on open-architecture Linux operating systems. This allows agencies to incorporate lane control signals into existing traffic cabinets without replacing their entire signal infrastructure.

Lane control signals are typically powered through cabinet or wired power connections tied into the traffic controller cabinet at the intersection or roadway location. Installation involves mounting signal heads overhead or on gantries, then wiring them to a compatible controller that manages activation based on traffic conditions or programmed schedules.
