In most European countries, regional and national plans are ‘spatial’ directing certain levels of development to specific cities and towns in order to support and manage the region depending on specific needs, for example supporting or resisting polycentrism.
Although the term "regional planning" is nearly universal in English-speaking countries the areas covered and specific administrative set ups vary widely. In North America, regional planning may encompass more than one state, such as the Regional Plan Association, or a larger conurbation or network of settlements. North American regional planning is likely to cover a much larger area than the Regional Assemblies of the UK; both, however, are equally "regional" in nature.
Specific interventions and solutions will depend entirely on the needs of each region in each country, but generally speaking, regional planning at the macro level will seek to:
