What do Transportation Engineers do?

Why Study Transportation?
• You have been affected by transportation issues already
• You are guaranteed to make an impact on everybody’s life
• It’s the melting pot of many interesting fields
• Virtually every aspect of the US economy is tied directly or
indirectly to highways
• Movement of people & freight
• Interstate Highway System was the largest civil
engineering project (built primarily in the 1960s & 70s)
• Designed with a 20 year lifespan… now what?!

Transportation Facts
• 3.9 million miles of public roads
• 2 million miles of oil and natural gas pipelines
• 120,000 miles of major railroads
• Over 25,000 miles of commercially navigable waterways• Over 5,000 public use airports
• Over 500 major urban public transit operators
• Over 300 ports on coasts, lakes, and inland waterways

Important and Emerging Issues
• US highway fatalities exceeded 50,000 in the 1970s
• Just over 32,000 fatalities in 2011

The Impact of Technology
• Advances in traffic signal timing
• Introduction of ITS

Human Behavior
• Dominance of private car usage
• Trips increased from 69% in 1960 to 90% now
• Occupancy within the vehicles has decreased from 1.22 to 1.09
• Strategies to increase car sharing• HOV, Toll Roads, HOT lanes
• Ride sharing
• Congestion!!!
• Fuel prices!!!

Human Behavior
• Many US metropolitan areas have experienced population
decline in central cities
• City sprawl to the suburbs
• Need for more highways and less efficient transit systems
• Employment has moved to suburbs
• Tendency toward low-density, private vehicle-based development
