What function do automated cameras serve at traffic lights?

Automated cameras at traffic lights primarily serve the function of taking photos of vehicles that run red lights. When a vehicle crosses the stop line after the traffic signal has changed to red, these cameras are triggered to capture images of the violation. This system is designed to improve safety at intersections by deterring drivers from running red lights, which can lead to accidents and injuries.

The implementation of these cameras helps law enforcement in issuing citations to offenders without needing an officer present at every intersection. This enhances enforcement capabilities and encourages compliance with traffic laws, ultimately promoting safer driving behavior and reducing the risk of collisions.

While analyzing traffic patterns, monitoring vehicle speeds, and providing live traffic updates are important in the broader context of traffic management, they are not the primary purpose of automated cameras at traffic lights.
