Traffic signal poles are essential infrastructure for guiding traffic and ensuring road safety. They are classified into different types based on structure, installation location and function. Here is a concise introduction to the main types.
Single-arm Traffic Signal Pole: The most common type, with a single horizontal arm extending from the pole body. It is widely used at intersections, crosswalks and small roads, suitable for areas with limited space and simple traffic conditions. It is easy to install and maintain, and cost-effective.
Double-arm Traffic Signal Pole: Equipped with two horizontal arms (left and right), usually used at large intersections with multiple traffic directions. It can install multiple signal lights to guide different lanes (e.g., straight, left turn, right turn) simultaneously, improving traffic efficiency.
Multi-arm Traffic Signal Pole: With three or more arms, designed for complex intersections (e.g., crossroads with multiple lanes, roundabouts). It can carry signal lights, road signs and surveillance cameras at the same time, integrating multiple functions to save space and construction costs.
Integrated Traffic Signal Pole: Combines traffic signals, street lights, surveillance cameras and road signs into one pole. It is widely used in urban main roads and new urban areas, featuring a neat appearance and reduced ground occupation, which helps optimize urban road landscape.
Pedestrian Signal Pole: A short pole (usually 2–3 meters high) installed near crosswalks. It is equipped with pedestrian signal lights (red/green walking signs) to guide pedestrians safely across the road, ensuring pedestrian traffic safety.
