Géographie des transports

Transport geography or transportation geography is a branch of geography that investigates the movement and connections between people, goods and information on the Earth's surface. Transportation geography detects, describes, and explains the Earth's surface's transportation spaces regarding location, substance, form, function, and genesis. It also investigates the effects of transportation on land use, on the physical material patterns at the surface of the earth known as 'cover patterns', and on other spatial processes such as environmental alterations. Moreover, it contributes to transport, urban, and regional planning. Transportation is fundamental to the economic activity of exchange. Therefore, transport geography and economic geography are largely interrelated. At the most basic level, humans move and thus interact with each other by walking, but transportation geography typically studies more complex regional or global systems of transportation that include multiple interconnected modes like public transit, personal cars, bicycles, freight railroads, the Internet, airplanes and more. Such systems are increasingly urban in character. Thus, transport and urban geography are closely intertwined. Cities are very much shaped, indeed created, by the types of exchange and interaction facilitated by movement. Increasingly since the 19th century, transportation is seen as a way cities, countries or firms compete with each other in a variety of spaces and contexts. In terms of transport modes, the primary forms are air, road, water, and rail. Each form has its own cost associated with 'speed of movement', which is affected by friction, place of origin, and destination. Ships are generally used for moving large amounts of goods. Maritime shipping is able to carry more around the world at a cheaper cost. For moving people who prefer to minimize travel time and maximize comfort and convenience, road and air are the most common modes in use. A railroad is often used to transport goods in areas away from water.
