What traffic signal control function is typically enabled by a police panel switch?

The police panel switch is primarily designed to enable traffic control functions that allow law enforcement to manage traffic signals during emergencies or specific situations. When the police panel switch is activated, it typically allows for the extension of stop time for vehicles, ensuring that they remain halted while the police are taking necessary actions, such as directing traffic or responding to an emergency.

This function is crucial as it provides law enforcement with the ability to create a safe environment, ensuring that vehicles do not proceed into potentially hazardous situations. It grants the authority to change the normal operation of traffic signals, impacting the flow of traffic based on immediate needs.

While change of light color, maximum cycle time, and pedestrian signal control might seem relevant in a traffic management context, they do not relate specifically to the functionalities typically controlled by a police panel switch. The emphasis on stop time allows for immediate and effective traffic management during critical incidents, highlighting the primary purpose of the police panel.
