A computer-aided dispatch system (CAD) primarily assists with:

A computer-aided dispatch system (CAD) is fundamentally designed to enhance the efficiency and effectiveness of police operations by automating the dispatching process and tracking officer activities in real-time. This system provides critical support for emergency service providers by receiving calls for service and effectively managing the allocation of resources, such as police units and emergency responders, to the scene of incidents.

Through a CAD, dispatchers can quickly assess ongoing situations, monitor officer locations, and ensure timely responses to incidents, thereby improving public safety. This immediate and organized communication between dispatchers and officers is vital for coordinating law enforcement efforts and providing necessary support on the ground.

While the other options may involve elements relevant to police work, they do not accurately capture the primary function of a computer-aided dispatch system. Storing officers' personal data, managing public relations efforts, and analyzing crime trends serve different aspects of law enforcement operations, but they do not directly relate to the operational capabilities of a CAD focused on dispatching and real-time tracking.
