C – Historical Evolution of Transportation I ■ 1. Transportation in the Pre-Industrial Era (pre 1800 s) ■ 2. The Industrial Revolution and Transportation (1800 -1870) ■ 3. Emergence of Modern Transportation Systems (1870 -1920)
1. Transportation in the Pre-Industrial Era (pre 1800 s) ■ Limited transport technology • • No mechanized forms of transportation. Harnessing animal labor and wind. Isolation and limited long distance trade. Reliance on maritime and fluvial transportation for long distance trade. • High value commodities (e. g. Silk Road). ■ Transportation and empire building • Roman Empire (road network, 80, 000 kilometers, 200 AD). • Chinese Empire (canal system, 2, 500 kilometers).

1. Transportation in the Pre-Industrial Era (pre 1800 s) ■ European expansion • Mastery of sailing and artillery. • Eastern trade route: • • Discovered by Portugal. Cape of good hope reached by 1481. Gama (1497 -99) first to reach India. China reached by 1513. • Western trade route: • • Discovered by Columbus (1492). Failed to reach Asia (America discovered). Cabot tried (1497), but also failed. Magellan (1519 -22) successful to round the world. • Establishment of colonial empires.

2. The Industrial Revolution and Transportation (1800 -1870) ■ Mechanization of transportation • Steam engine (as a water pump). • First steamship on the Delaware river (1790). • Would lead to the development of railways. ■ Regular maritime routes • Notably over the North Atlantic (Europe – North America). • The era of clipper ships: • Fast cargo ships used for intercontinental trade (Asia, Europe, America). • The emergence of the steamship: • Savannah (first to cross the Atlantic in 1820). • Great Britain (first steel and helix propelled ship, 1844).

2. The Industrial Revolution and Transportation (1800 -1870) ■ Land transport systems • Serious problems of land transportation. • Roads were commonly unpaved and could not be used to effectively carry heavy loads. • Attempts to develop toll road systems (Turnpikes in UK). ■ Freight shipping canals • Bridgewater Canal, Britain, 1761. • Erie Canal, New York, 1825. • Linking different segments of fluvial systems into a comprehensive waterway system. • Fluvial barges. • Lowered significantly land transport costs. • Permitted initial industrialization.

2. The Industrial Revolution and Transportation (1800 -1870) ■ Railway systems • First commercial rail line in 1830 (Manchester. Liverpool; 40 miles). • Access to national resources and markets: • The triumph of inland transportation. • First urban systems. • End of the canal era: • Many canals fell into disrepair. • Unable to compete with the speed and flexibility of rail. • Only the most strategic links were kept. • From a point-to-point to an integrated rail system: • Large companies. • Standard gauge.

3. Emergence of Modern Transportation Systems (1870 -1920) ■ Growth of international transportation • Shift from coal to oil in ships: • Reduce their energy consumption by a factor of 90%. • Increase in ship size (no longer limited by wood). • Construction of the Suez and Panama canals. ■ Dominance of the rail transport system • By the early 20 th century, most systems reached their peak. • Overinvestment and over development. • A phase of decline then began.

3. Emergence of Modern Transportation Systems (1870 -1920) ■ Modern urban transportation • Increase in urban population. • Introduction of tramways (1880; horse drawn, and then electric). • Urban sprawl and the specialization of economic functions. • Underground metro systems in large cities (London, 1863). • Bicycle (1867); cheap mobility for the masses. ■ Modern telecommunications • Telegraph (1844). • Associated with the growth of railways and international shipping. • Business transactions became more efficient.

1. Transportation in the Fordist Era (1920 -1970) ■ Internal combustion engine • Diesel engine (1885). • Extended flexibility of movements. • Fast, inexpensive and ubiquitous transport modes (cars, buses and truck). ■ Mass production system • Applied by Ford for car manufacturing. • Ford Model T: about 14 million Ford Model T were built (1913 -1927). • Increased demand for oil products and other raw materials (steel and rubber).

3. Future Transportation ■ Cyclic character of transport innovations • Innovations lead to a wave of development. • Introduction: • Private entrepreneurs and innovators. • Growth: • Fast adoption. • Often involves a “paradigm shift” event. • Maturity: • Maximal spatial coverage. • Government involvement (investment, regulations, etc. ) • Rationalization/obsolescence: • Diminishing returns (Segment or system-wide). • A mix of regulations (protect public interests) and deregulations (increase productivity). • Our current freight transport systems are in a phase of rationalization.
