B – A Diversity of Modes • 1. Road Transportation • 2. Rail Transportation • 3. Pipelines • 4. Water Transportation • 5. Air Transportation • 6. Modal Competition
1. Road Transportation • Overview • Large consumers of space. • Lowest level of physical constraints among transportation modes. • Environmental constrains are significant in road construction. • Average operational flexibility (vehicles can serve several purposes). • High maintenance costs, both for the vehicles and infrastructures. • Linked to light industries (rapid movements of freight in small batches).
1. Road Transportation • History • The first land roads were trails (hunting). • With the first nation-states trails started to be used for commercial purposes. • Domestification of animals such as horses, mules and camels. • Wheeled vehicles encouraged construction of better roads. • Requires a level of labor organization and administrative control: • Provided by a central government offering a level of military protection over trade routes. • 3,000 BC the first road systems in Mesopotamia. • Roman Empire 300 BC built the first comprehensive road network.
1. Road Transportation • Modern road networks • Creation of modern nation-states (17th century): • National road transportation systems were formally established. • France: Royal Roads system spanning 24,000 km. • Great Britain: 32,000 km system of private toll turnpikes. • United States: 3 million km of roads, most unpaved, was in operation by the early 20th century. • Road engineering • Construction of reliable and low cost hard surface roads. • Scottish engineer McAdam developed a process: • Hard and waterproof road surfaces made by cemented crushed stone, bound together either with water or with bitumen. • Improved the reliability and the travel speed on roads.
1. Road Transportation • National highway systems • Road development accelerated in after WWII. • American Interstate highway system: • Initiated in 1956. • About 56,000 km was built from the 1950s to the 1970s. • Additional 9,000 km between 1975 and 1998. • Overall, about 70,000 km of four-lane and six-lane highways were constructed. • Linking all major American cities, coast to coast. • Trans-Canada highway completed in 1962. • By the 1970s, every modern nation has constructed a national highway system.
1. Road Transportation • Public sector • Main supplier of road transport infrastructures. • Unpractical to use a similar pricing system than a commercial enterprise. • Most roads are not economically profitable but must be socially present as they are essential to service populations. • Only possible on specific trunks that have an important and stable traffic. • Toll roads: • Highways linking large cities. • Bridge and tunnels. • Can expropriate the necessary land for road construction. • Economies of scale and their indivisibility.
1. Road Transportation • Costs • Rights of passage. • Development costs (planning). • Construction and expropriation costs. • Maintenance and administration costs. • Losses in land taxes (urban environment). • External costs (accidents and pollution). • Income • Registration. • Gas (taxes) • Purchases of vehicles (taxes). • Tolls, parking, and insurance fees.
2. Rail Transportation • Overview • Composed of a traced path on which are bound vehicles. • Average level of physical constrains: • Linked to the types of locomotives. • Affected by the gradient. • Heavy industries are traditionally linked with rail transport systems. • Containerization: • Improved the flexibility of rail transportation. • Linking it with road and maritime modes.
2. Rail Transportation • Geographical setting • Established differently because different goals were to be achieved. • Access to resources. • Servicing regional economies. • Territorial control. • Rail monopolies • High level of economic and territorial control. • Monopoly in Europe and oligopoly in North America. • Regular (scheduled), but rigid, services. • Transport mode the most constrained by the physiography.

2. Rail Transportation • Economic rationale • Market area and capacity: • Transport raw materials over long distances. • Move passengers and freight (cars, agricultural equipment, etc.) • The average length was 1,300 km compared with 700 km for trucks. • Intermodal integration favored segmentation and specialization. • Costs: • High construction and maintenance costs. • Shipping costs decrease with distance and load. • Transshipments and train assembly increase costs. • Rail operating costs: labor (up to 60%), locomotives (16%) and wagons, fuel, maintenance and equipment (24%).
2. Rail Transportation • Benefits: • Accelerated the industrialization process. • Accelerated economic development and human settlements. • Multiplier effects on industrial activities. • Safety; after air transportation, the safest mode. • Regulation: • Highly dependent from government subsidies. • Governments financing, mainly for the sake of national economic imperatives.
2. Rail Transportation • High speed train networks • Require special lines, but can also use the existing lines at a lower speed • Speed of about 300 km/h. • Separation between passenger and freight traffic. • By-passing several centers of less importance. • Over average distances, they have proved to be able to compete effectively with air transportation.

3. Pipelines • Overview • Single purpose: carry one commodity from a location to another. • Built largely with private capital: • Has to be in place before any revenues are generated; significant capital commitment. • Large quantities of products where no other feasible means of transport (usually water) is available. • Two main products dominate pipeline traffic: • Oil and gas. • 17% of all tons-km in the US. • Locally pipelines are significant for the transport of water. • Low physical constraints: • The landscape and pergelisol in arctic / subarctic environments.
3. Pipelines • Pipeline systems • Construction costs vary according to the diameter: • Increase proportionally with the distance and with the viscosity of fluids. • Longest pipelines: • Gas pipeline: Alberta to Sarnia (Canada); 2,911 km. • Oil pipeline: Transiberian; 9,344 km in length. • Trans Alaskan pipeline: • 1,300 km long. • Built under difficult conditions. • Above the ground for most of its path. • System has very little flexibility: • Cannot respond well to geographical fluctuations of the supply or demand.

4. Water Transport • Issues • Dominant support of global trade: • International and seaborne trade are interrelated. • 96% of the world trade is carried by maritime transportation (mass). • International trade and maritime transportation: • Interrelated. • 25,000 billion tons-km are on average transported annually. • 7,000 by rail and 3,000 by road. • 71% of all freight shipped globally. • For every $1,000 of exports, there is one ton of freight being shipped by maritime transportation.

4. Water Transport • Domains of maritime circulation • Geographical by its physical attributes: • 71% of the terrestrial surface. • Strategic by its control. • Commercial by its usage. • Maritime routes • Corridors of a few kilometers in width. • Trying to avoid the discontinuities of land transport. • Function: • Obligatory points of passage, which are strategic places. • Physical constraints (coasts, winds, marine currents, depth, reefs, ice). • Political borders. • The majority of maritime circulation takes place along coastlines.

4. Water Transport • Maritime enclaves • Countries that have difficulties to undertake maritime trade: • Not part of an oceanic domain of maritime circulation. • Requires agreements with neighboring countries: • Access to a port facility through a road, a rail line or through a river. • Not necessarily imply an exclusion from international trade: • Substantially higher transport costs. • On average 50% higher than countries that are not landlocked. • Less than 40% of the trade volume of the median coastal country. • May impair economic development.

4. Water Transport • Global fleet • About 85,000 ships of more than 100 tons. • Half of them performing transport functions and the other half performing service functions (e.g. tugs). • Growth of the number of ships as well as their average size. • Oceanic maritime traffic dominantly concerns freight.
4. Water Transport • Passenger vessels • Passenger ferries: • People are carried across relatively short bodies of water in a shuttle-type service. • Tend to be small and fast vessels. • Cruise ships: • Passengers are taken on trips of various durations, usually over several days. • Usually very large capacity ships. • Before air transportation, serviced by liner passenger ships, dominantly over the North Atlantic. • Roll on-Roll off (RORO) vessels • Allow cars, trucks and trains to be loaded directly on board. • The largest are the car carriers that transport vehicles from assembly plants to the main markets.
4. Water Transport • Bulk cargo • Freight, both dry or liquid, that is not packaged. • Minerals (oil, coal, iron ore) and grains. • Requires the use of specialized ships such as oil tankers as well as specialized transshipment and storage facilities. • Single origin, destination and client. • Prone to economies of scale. • Break-bulk cargo • General cargo that has been packaged in some way with the use of bags, boxes or drums. • Numerous origins, destinations and clients. • Before containerization, economies of scale were difficult to achieve.
4. Water Transport • Growth of maritime traffic • Increase in energy and mineral cargoes: • Growing demand from developed economies. • Many developing countries, such as China, are also increasingly involved in importing raw materials. • Globalization: • International division of the production and trade liberalization. • Technical improvements in ship and maritime terminals. • Economies of scale: • Remain a low cost mode. • Strengthened by containerization

4. Water Transport • Technical innovations • Size: • Expresses type as well as capacity. • Each time the size of a ship is doubled, its capacity is cubed. • The largest tankers (ULCC) are around 500,000 dwt • The largest dry bulk carriers are around 350,000 dwt. • Remaining constraints in ship size are the capacity of ports and canals. • Speed • Average speed of ships is about 15 knots (1 knot = 1 marine mile = 1,853 meters), which is 28 km per hour. • A ship can travel about 575 km per day. • Recent ships can travel at speeds between 25 to 30 knots (45 to 55 km per hour). • Reaching higher maritime speeds remains a challenge which is excessively costly to overcome.
4. Water Transport • Specialization of ships: • General cargo ships, tankers, grain carriers, barges, mineral carriers, bulk carriers, methane carriers and container ships. • Ship design: • The hulls are the result of considerable efforts to minimize energy consumption, construction costs and improve safety. • A ship can take between 4 months (container and crude carriers) and 1 year to build (cruise ship). • Automation: • Self-unloading ships • Computer assisted navigation (crew needs are reduced and safety is increased) and global positioning systems. • Smaller crews being required to operate larger ships.
4. Water Transport • Flags of convenience • 46% of the ships and about 62% of the global tonnage (1998). • Regulation: • Under maritime law, the owner is bound to the rules and regulations of the country of registration. • Registry costs: • Registry costs are on average between 30 to 50% lower than those of North America and Western Europe. • Operating costs: • From 12 to 27% lower than traditional registry fleets. • Savings are coming from lower manning expenses. • Lower standards in terms of salary and benefits.
