The primary function of the Central Management Unit (CMU) is to prevent conflicting signal indications. This is a critical aspect of traffic signal control systems, as conflicting signal indications can lead to unsafe conditions for motorists and pedestrians. The CMU plays an essential role in ensuring that the signals are synchronized and that the correct phases are activated without overlap that could cause accidents or confusion at intersections.

While controlling traffic flow, managing power supplies, and monitoring signals remotely are important tasks related to traffic management, the prevention of conflicting indications is a fundamental safety measure that directly impacts the integrity of traffic control operations. By continuously analyzing traffic patterns and signal phases, the CMU ensures that signals are coordinated effectively, reducing the risk of accidents that may arise from simultaneous green lights for intersecting traffic. This foundational safety feature is what makes the CMU integral to the successful functioning of modern traffic signal systems.
