What is a common use for signal poles aside from supporting traffic lights?

Signal poles serve multiple purposes, and one of the most common uses beyond supporting traffic lights is for traffic cameras. Traffic cameras are often mounted on signal poles to monitor vehicular traffic, enforce traffic laws, and enhance safety at intersections. This integration allows for efficient data collection and live monitoring without the need for additional infrastructure, making signal poles an ideal location for camera installation.

While options such as advertising banners, flag displays, and city decorations can also be associated with signal poles, they are not as universally recognized or prevalent as the use of traffic cameras. Traffic cameras are specifically designed to be part of the traffic management system, capturing images for enforcement and analysis, thereby directly contributing to road safety and traffic regulation.
