What does the acronym CBD stand for in urban planning?

In urban planning, the acronym CBD stands for Central Business District. This term refers to the commercial and business center of a city, typically characterized by a high concentration of retail, office buildings, and cultural institutions. It serves as the hub for economic activities, where businesses and services are concentrated, thus driving urban growth and development. The Central Business District is often distinguished by its dense layout, accessibility, and proximity to transportation nodes, making it a crucial area for both daytime and night-time activities within the city. This area is vital for urban planning as it influences land use patterns, zoning regulations, and overall city dynamics.
