Pedestrian or sidewalk flow refers to the movement and circulation of people on foot along a designated path or walkway, typically found in urban areas. It encompasses the natural rhythm and pace at which individuals navigate through a shared space, taking into account factors such as foot traffic, obstacles, and social interactions. This term is often used to describe the efficiency and ease of movement within a pedestrian-friendly environment, and is an important consideration in urban planning and design. A smooth and harmonious pedestrian or sidewalk flow can enhance the overall experience of a city and promote a sense of community and connectivity among its inhabitants.
