Traffic Signal Heads

The three primary types are vehicle traffic signals controlling intersection flow, pedestrian signals indicating walk and don't walk phases, and special-purpose signals such as lane-control, flashing beacons, or railroad crossing signals. Each type communicates specific right-of-way instructions to a designated road user group.

A pedestrian head, also called a pedestrian signal, is a dedicated display unit that shows walking person and raised hand symbols to indicate when pedestrians may safely cross an intersection. These units are typically mounted separately from vehicle signal heads and often include audible or countdown timer features for accessibility.

Traffic signal head housings are commonly manufactured from polycarbonate or aluminum for durability and weather resistance. Polycarbonate housings offer lightweight, impact-resistant construction while withstanding UV exposure and extreme temperatures, making them a popular choice for long-term intersection installations across diverse climates.

Traffic signal equipment is typically required to comply with NEMA TS-1 and TS-2 standards, Caltrans 33x specifications, and ATC or ITS cabinet compatibility requirements. Compliance ensures interoperability with existing traffic controllers and cabinets used by state and local transportation agencies.

Signal detection equipment supporting traffic signal heads is commonly available in single, dual (two-channel), and four-channel configurations. This range allows agencies to match detection capacity to intersection complexity, from simple two-lane crossings to multi-approach signalized intersections requiring extensive vehicle detection coverage.
