The urban spatial structure varies according to the scale being considered since each scale is linked with specific mobilities. 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, which tend to be clustered. At the city level, highways, transit systems, and major transport terminals are the dominant elements impacting the spatial structure.
