1. Chapter 9 Transportation and Communications Understanding modern transportation and communications systems Point out historically specific nature of these systems Cost-space & time-space convergence Transportation & economic development Transportation policy Innovations in transportation in U.S. metro areas Communications innovations & computer networks Social & economic impacts of the Internet Likely future impacts of IT

2. Transport Networks: An Historical Perspective The capitalist imperative & the development of transportation technologies Site & situation – in time and space Improvements in transport promote the division of labor – specialization – and trade, Fig 9.1 This helps improve productivity and raise real wealth – but there are distributional consequences “In today’s world, almost nothing is consumed where it is produced; …” p. 286 Really? Transportation innovations & impacts on the developing world (picture p. 291)

3. European High Speed Rail: where are we?

4. Network Options – Fig 9.3 Least Cost to Use A B C D Maximum Connectivity Least Cost to Build Hybrid A DC B A B C D High Travel Costs AC, BD Benefit-Cost Evaluation of Network Choice: - Benefits: relative travel cost (savings), interaction - Costs: investment, operations

5. Evaluating Networks for Maximum Net Benefits Ullman’s Famous Map of Railway Traffic                   (a) (b) (c) (d) 5 37 4 10 Cost = 10 Revenue = 15 Net Benefit = 5 Cost = 12, R = 18 Net Benefit = 6 Cost = 14, R = 25 Net Benefit 11 Cost = 19, R = 29 Net Benefit = 10

7. Taaffe, Morrill & Gould Similar to Fig 10.3 Vance’s endogenic And exogenic model The cumulative Causation concept Hoyle

8. Spatial Impact of Transport Improvements – Cost Space and Time Space Convergence 1. Demand for Accessibility 2. Technological Development 3. Transport Innovation 4. Time-space convergence 5. Spatial adaptation to changes in time- space organization (centralization and specialization 6. Increased Interaction Search Janelle model

9. Key Consequences of Janelle Model Long-run decrease in friction of distance Distance Interaction t1t1 t2t2 t3t3 Due to innovations in transportation methods and improvements in media themselves Result: Lowered average ton-mile costs of transportation and decreased importance of transport costs as a factor cost  AND other costs rise in importance

10. Consequences of Janelle Model, Cont. The spatial pattern of production moves from dispersed…….. C1C1 C2C2 C3C3 M1M1 M2M2 M1M1 M1M1 L1L1 L2L2 L3L3

11. Consequences of Janelle Model, Cont. To concentrated, taking advantage of the intrinsic comparative advantages of resource supplies C1C1 C2C2 C3C3 M1M1 M2M2 M1M1 M1M1 L1L1 L2L2 L3L3 L*L* M1M1 Resulting in (1) geographic specialization, (2) increased spatial extent of production, (3) greater interaction (consider this model operating across many industries)

12. Examples of Janelle Model Steam-powered railroads versus waterborne sailing vessels & canal era or overland by horse-drawn wagons. Fig 9.7 Development of Interstate Highway System Development of intermodal cargo-container system (ship/rail) ? What about in the services? Clearly impact in business/tourist services. But what about the Internet? Figure 9.8 – disappearance of long-distance telephone rates

13. Adaptation of Borchert model

14. General Properties of Transport Costs

15. Curvilinear Transport Costs

16. Variations in Transport Costs Among Modes Distance Transport Cost/Unit Weight Truck Rail Ship Pipeline Air TRS

17. Factors Influencing Transport Rates 1.Grouping freight rates into zones 2. Variations due to commodity characteristics (a) Differences in cost of service related to: (1) Loading characteristics (2) Size of shipment (3) Perishability and risk of damage (b) Elasticity of Demand for Transportation 3. Variations due to traffic characteristics (a) intermodal competition (b) traffic density (c) direction of haul

18. General Relationship Between Distance and Unit Cost per ton-mile Distance Quantity $

19. Factors Influencing Transport Costs International shipping regimes (cargo container carriers & ports) Location of high-tech – often near airports Free trade zones Deregulation and privatization Development of networks (esp. airline – hub & spoke vs. complex point to point) Figure 9.14 (one not two carriers!) Figure 9.19: Yucca Mtn. still controversial
