  1. MEGALOPOLIS (CHAPTER 4: PART 2)

  2. WHERE’S MEGALOPOLIS?

  3. 1990 2000

  4. URBAN LANDSCAPES • Major Components: • 1. Spatial Interaction • 2. Functional Complexity • 3. Public Services • 4. Accessibility • 5. Intensity of Change

  5. MAJOR COMPONENTS(CONTINUED) • Spatial Interaction • refers to the movement that occurs between places • people, via sidewalks, parking lots, subways • information, via communication lines, wires, terminals • utilities, e.g., sewage, water, electricity, and gas

  6. WASHINGTON, D.C. SPATIAL INTERACTION

  7. NYC SPATIAL INTERACTION

  8. SPATIAL INTERACTION

  9. MAJOR COMPONENTS(CONTINUED) • Functional Complexity • refers to the land use variations and conflict • related to competition for residential, industrial, commercial, or institutional purposes, or parks and recreational areas.

  10. FUNCTIONAL COMPLEXITY

  11. FUNCTIONAL COMPLEXITY

  12. FUNCTIONAL COMPLEXITY

  13. MAJOR COMPONENTS(CONTINUED) • Public Services… • provide water, sewage, garbage pick-up, etc. • also include: police protection, fire protection, public schools, road works, and health care

  14. PUBLIC SERVICES

  15. PUBLIC SERVICES

  16. PUBLIC SERVICES

  17. MAJOR COMPONENTS(CONTINUED) • Accessibility… • is created and maintained as a public service to insure access to the core from the periphery and among places along the periphery. • is accomplished via bypasses, beltways, parkways, and limited access expressways.

  18. ACCESSIBILITY

  19. MAJOR COMPONENTS(CONTINUED) • Intensity of Change • Refers to the dynamic nature of the urban landscape • Nothing seems permanent. • Economic ventures, shifts in transportation networks, and developments and declines in residential areas are typical of the continual changes

  20. INTENSITY OF CHANGE

  21. BOSTON’S “BIG DIG” INTENSITY OF CHANGE

  22. PATTERNS OF CHANGE • Agriculture • Land prices • Channelized development • Outmigration

  23. AGRICULTURAL CHANGE • Vast acreages of field crops have long been replaced by table or specialty crops • Dairy products, tomatoes, lettuce, berries, and vegetables • High value • Perishable • Require considerably less land

  24. LAND PRICES • Tremendous increase in the cost of land throughout the region • Prices have steadily increased outside the CBD, especially along transportation corridors. • Current residential location trend • Smaller lots and subdivisions • Outside the city

  25. PATTERNS OF CHANGE(CONTINUED) • Channelized Development • Growth has occurred along major arterial highways. • Development is both commercial and residential. • Outmigration • Movement continues away from the center city residential areas. • Settlement has extended beyond suburbs to “ruburbs” and “exurbs.” • Made possible by mass transit systems and beltways or highways.

  26. PROBLEM AREAS • KEY SOURCES • Density • Accessibility • Spread

  27. DENSITY

  28. PROBLEM AREAS • Density • Solid waste disposal • Water • Air • Noise pollution • Accessibility • Creates congestion • Should we increase the sizeorefficiency of transportation networks? • Spread • Promotes both environmental and social problems.

  29. INCREASE SIZE OR IMPROVE EFFICIENCY?
