Borchert’s Model
describes urban growth based on changes in transportation technology over time
Sail-Wagon Epoch
(1790-1830); water ports were important, poor road conditions made long travel difficult
Iron Horse Epoch
(1830-1870); Steam engines powered boats, regional rail network connected cities, rail lines connected resources and industrial sites
Steel Rail Epoch
(1870-1920); transcontinental railways, cities emerged along lines in the interior of continents
Auto-Air-Amenity Epoch
(1920-1970); cars allowed cities to spread out, air-port hubs, cities were fare more interconnected
Pedestrian Cities
Urban centers shaped by the distances people could walk
Streetcar Suburbs
Communities that grew up among rail lines creating a pin-wheel shaped city
Urban System
an interdependent set of cities within a region (ex: US and Canadian cities in the Great Lakes region)
Gravity Model
Places that are larger and closer together will have a greater interaction than places that are smaller and farther away from each other
Rank-Size Rule
The nth largest city in any region will be 1/n the size of the largest city
