What does the term "conflict monitor" refer to?

The term "conflict monitor" refers to a device that plays a critical role in traffic signal operations by detecting faults and potential conflicts within the system. Its main function is to ensure that the traffic signals are operating correctly and safely. By monitoring the signals, it can detect situations where conflicting movements might occur, such as when vehicles could inadvertently be given a green light at the same time in conflicting directions. This capability is essential for preventing accidents at intersections and ensuring smooth traffic flow.

The other options focus on different aspects of traffic management and safety. Monitoring real-time traffic is generally related to traffic flow analysis, while vehicle speed detection is more about gathering data for enforcement. Technologies aimed at pedestrian safety tackle issues specific to protecting pedestrians crossing at intersections but do not directly relate to monitoring signal operation faults like a conflict monitor does.
