How does an island with a beacon in the center of a zebra crossing affect the crossing?

The presence of a beacon in the center of a zebra crossing indicates that it splits the crossing into two separate crossings, creating a safer environment for pedestrians. This design allows pedestrians to cross in two steps, pausing in the middle if needed, which is particularly beneficial when there is heavy traffic. The beacon serves as a visual signal for both drivers and pedestrians, alerting them to the crossing area. It enhances visibility and safety by making pedestrians more conspicuous to oncoming vehicles.

While there may be other features associated with a zebra crossing, such as signaling for pedestrians, the beacon specifically creates a divided crossing, facilitating safer passage for individuals on foot. The other options do not accurately reflect the function of the beacon; for example, it does not indicate a pedestrian-only crossing, prohibit crossing, or merely serve as a refuge. The correct answer fundamentally relates to the improved safety and structure that the beacon provides.
