What can be inferred about Dean Street based on the provided information?

The inference that Dean Street is a two-way street indicates that both directions of traffic are allowed to use the street simultaneously. This conclusion may stem from contextual clues or specific references to the street's design, signage, or regulations that permit vehicles to move in both lanes. Two-way streets typically allow for a more flexible flow of traffic and can accommodate a variety of vehicles traveling in opposing directions.

Understanding the characteristics of two-way streets, such as their layout, signage, and the way they facilitate traffic movement, is essential for train operators and other transportation professionals. Proper knowledge ensures that operators can navigate around such streets safely and effectively, following applicable regulations and ensuring that all road users can coexist without risk.

In contrast, the other options suggest characteristics that would limit or alter traffic flow in specific ways—like being one-way, having no traffic, or being exclusive to pedestrian use—which contradicts the deductions drawn about Dean Street serving as a two-way thoroughfare.
