12
Modes For hire (public) –contract carrier –common carrier (buses and taxis) Not For hire (private)
13
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
14
EOS Exists when FC are high and VC is low Which transportation modes have EOS?
15
Freight Motor Carriers –25.4 % of intercity freight –72% of revenues Railroads –26% of intercity freight –5% of revenue
16
Freight Pipelines –16.3% of intercity freight –3% of revenue Water - Inland and Coastal –24.4% of intercity freight –4.1% of revenue
17
Freight Airplanes –0.1% of intercity freight –2.3% of revenue Parcel, Postal Courier –0.4% of intercity freight –9.2% of revenue
