Passage B Transportation Modes （II） Air transportation Air routes are practically unlimited, but they are denser over the North Atlantic, inside North America and Europe and over the North Pacific. Air transport constraints are multidimensional and include the site (a commercial plane needs about 3,300 meters of runway for landing and taking off ), the climate, fog and aerial currents. Air activities are linked to the tertiary and quaternary sectors, notably finance and tourism, which lean on the long distance mobility of people. More recently, air transportation has been accommodating growing quantities of high value freight and is playing a growing role in global logistics. Intermodal transportation Concerns a variety of modes used in combination so that the respective advantages of each mode are better exploited. Although intermodal transportation applies for passenger movements, such as the usage of the different, but interconnected modes of a public transit system, it is over freight transportation that the most significant impacts have been observed. Containerization has been a powerful vector of intermodal integration, enabling maritime and land transportation modes to more effectively interconnect. Unit 3 An Overview of Transportation
Unit3 AnOverviewofTransportationTelecommunicationsCover a grey area in terms of if they can be considered as a transport modesince unlike true transportation, telecommunications often does not havephysicality. Yet, they are structured as networks with a practically unlimitedcapacity with very low constraints,which may include the physiography andoceanic masses that may impair the setting of cables. They provide for theinstantaneous movement of information (speed of light intheory). Wavetransmissions,because oftheir limited coverage,oftenrequire substations,suchas for cellular phone networks. Satellites are often using a geostationary orbitwhich is getting crowded. High network costs and low distribution costscharacterize many telecommunication networks,which are linked to the tertiaryand quaternary sectors (stock markets, business to business informationnetworks, etc).Telecommunications can provide a substitution for personalmovementsinsomeeconomicsectors
