Scale and Urban Spatial Structure
The urban spatial structure varies according to the considered scale, since each of them is linked with the generation and attraction of specific movements. At the community level, the urban spatial structure is influenced by the street pattern and the location of residences and basic services. A "community" can also be a cluster of commercial, distribution or manufacturing activities. At the district level, which can be seen as a conglomeration of various communities, the urban spatial structure is influenced by main roads and specific employment zones. At the city level, highway, transit systems and major transport terminals are the dominant elements impacting the spatial structure.
