Answer 1

A controlled railway crossing may have a stop sign, a flagperson, or an electrical or mechanical signaling device.

Step-by-step explanation:

A controlled railway crossing may have any of the above, including a stop sign, a flagperson, or an electrical or mechanical signaling device. These measures are implemented to ensure the safety of both drivers and pedestrians. For example, a stop sign alerts drivers to come to a complete stop before proceeding, while a flagperson helps to direct traffic during specific times. Additionally, an electrical or mechanical signaling device, such as a traffic signal, controls the flow of vehicles and pedestrians at the crossing.
