Urban Sprawl: What is it?
The uncontrolled spread of urban development into neighboring regions.
Urban Sprawl:
Began accelerating after WWII
Vehicle population has grown 6 times faster than human population since 1969
Between 1970 and 1990, vehicle miles traveled increased 98% while population grew 23%
Suburban population has grown 10 times faster than central city population.
Vehicle vs. Human population in the U.S.A
Vehicle Population
Human Population
For every 1000 people, there are 797 vehicles.
Problems: Challenges due to urban sprawl
Vehicle Dependency
Issues Concerning Vehicle Dependency
Washington DC
DC workforce: 671,000
Commuters: 481,000
Commuting via personal vehicle: 50% 240,500
30 miles/gallon
Average one-way commute: 30 miles
CO2 emission: 1 gallon = 18 lbs
Total CO2 emission in one day
8.65 million pounds.
Equivalent of burning 1513 tons of coal.
Public Transit:
Limited Routes
Cost of permit
Land use
Lower GHG emission
For 100 miles traveled per person
Cars: 89 lbs CO2, Buses: 14 lbs CO2
Switching car to public transport saves $9,224
Congestion Socio-Economic Effects
Late deliveries
Higher fuel costs
Missed connections
Lost business opportunities.
Reduced market areas;
Increased inventories;
Costs for additional crews and decentralized operations to serve the same market area.
Transit Oriented Development
Sufficient density to encourage public transit
Connect residences, jobs, and retail.
Mixed use development
Grid transportation network
Urban design guidelines and features.

Halts sprawl development
Mimicking DC and New York
What is it?
Achieving Transit Oriented Development
Using economic incentives

Example: DC Beltway
Northern VA HOT lanes
Market Failures:
Developers paying for utilities
Efficiently implemented transit vs. Current Sprawl Model
GHG emission reduction
Cost reduction
Congestion reduction
American population traveling from suburbs: 32% CO2 emission.
Cost Analysis
