Final answer:
The correct answer is 'Pedestrian;' pedestrian areas in cities are designed for walking only, and these zones exclude vehicles to ensure the safety of walkers, much like the conversion of an avenue in Curitiba into a pedestrian street.
Step-by-step explanation:
Pedestrian. A pedestrian area in a city is a zone designated exclusively for walking, where vehicles, including bikes, are generally not allowed. This is to create a safe and pleasant environment for people to walk, shop, and enjoy the cityscape without the interference of motorized traffic.
These areas are significant in urban settings to ensure the safety and comfort of individuals on foot. The concept is akin to certain city strategies, like the one employed in Curitiba, Brazil, where a main avenue was suddenly turned into a pedestrian-only street, which eventually became a highly visited section of the city. This illustrates how pedestrian zones can enhance the urban experience by prioritizing walkability over vehicular access.
When navigating a city like New York, as figure 3.2 suggests, both walkers and drivers have to follow a zigzagged path following roads and sidewalks, which is a form of two-dimensional motion. Such motion is more pronounced in pedestrian areas, where the layout is designed with the comfort and ease of pedestrians in mind.
