multiple-nuclei model

A model of urban structure where cities have multiple centers of activity, each with its own distinct functions and characteristics.In urban geography, the concept of polycentric urban structure refers to a model of city organization that deviates from the traditional monocentric layout. In this model, cities are characterized by the presence of several centers of activity, each serving as a focal point for specific functions and activities. These centers can vary in size, function, and importance, creating a more diverse and dynamic urban landscape. For example, a city may have a central business district, an industrial zone, a cultural district, and a residential area, each with its own unique characteristics and amenities. This multi-centered approach to urban planning can lead to more efficient land use, reduced traffic congestion, and a more balanced distribution of resources and services throughout the city. By promoting decentralization and diversity, polycentric urban structures can help create more resilient and sustainable cities that better meet the needs of their residents.
