What is the best method to expedite passengers moving in and out of train cars?

Making announcements over the intercom is an effective method to expedite passengers moving in and out of train cars because it provides clear and timely communication about what passengers need to do. Announcements can inform passengers about important details, such as the next stop, the time available for boarding, and any protocols they should follow, which helps to manage the flow of people efficiently.

This form of communication helps reduce confusion and increases the likelihood that passengers will board and disembark in an orderly manner. When passengers are well-informed and understand the urgency of moving quickly, they are more likely to comply, thereby improving the overall speed of the boarding and alighting process.

In contrast, other methods may not have the same level of impact. For example, keeping doors open longer might not effectively encourage faster movement, as it could lead to delays if passengers linger. Using hand signals can be helpful in specific contexts but may not effectively communicate to all passengers quickly or clearly, especially in larger crowds. Rushing passengers can create confusion and safety hazards, leading to more delays rather than improving efficiency.
