Questions
• How does the internet effect travel?
• What would happen to Albany if HSGT (300 mph) was begun between NYC & Albany?
• What are the common threads among the “new” transportation modes through the ages (What are “new” transportation modes)
Transportation Demand
• System serves people’s economic, social, & cultural activities
• derived or indirect demand - people move due to need not desire– The only time you really desire to drive is when
you first get your license (before you start chauffeuring you siblings)
System
• Fixed Facilities
• Flow entity
• Control system– vehicular control– flow control
System Classification
• 3 major classes– ground– air – water
• 5 major modes
Modes
• Highway– car– taxi– truck– bus– bicycle– pedestrian
Modes
• Rail– Passenger– freight
• Air– private– commuter– jets– freighters
Modes
• Water– Inland Waterway– canals– ocean going
• Pipelines– liquids and gases
Modes
• For hire (public)– contract carrier– common carrier (buses and taxis)
• Not For hire (private)
Cost
• Fixed Costs - build it, maintain it, operate it– not related to production or utilization
• Variable Costs - depend on utilization
• Variable cost / fixed cost gives economy of scale (EOS)
• EOS - production increases $/unit decreases, profit increases
EOS
• Exists when FC are high and VC is low
• Which transportation modes have EOS?

Freight
• Motor Carriers– 25.4 % of intercity freight– 72% of revenues
• Railroads– 26% of intercity freight– 5% of revenue
Freight
• Pipelines– 16.3% of intercity freight– 3% of revenue
• Water - Inland and Coastal– 24.4% of intercity freight– 4.1% of revenue
Freight
• Airplanes– 0.1% of intercity freight– 2.3% of revenue
• Parcel , Postal Courier– 0.4% of intercity freight– 9.2% of revenue
Travel
• People look at $, time, schedule, service
• Need to look at total travel time– Is it faster to drive or fly to Washington, DC?– Driving 7:00 390 miles cost: $393.90 rt– Flying 1:15 to Albany, 1:00 wait, 1:20 flying,
1:20 into city Cost: $322 rt
Questions
• What accounts for the difference in the percentage of freight carried and the revenues?
• How will intermodal freight ventures help to increase revenues (profits) for trucks, rail, shipping?
