Topic 4 – Transportation Terminals The Function of Transport Terminals Ports and Rail Terminals Airport Terminals Terminals and Security
A – The Function of Transport Terminals • 1. The Nature of Transport Terminals • 2. Passengers Terminals • 3. Freight Terminals • 4. Terminal Costs
1. The Nature of Transport Terminals • Concept • All spatial flows, with the exception of personal vehicular and pedestrian trips, involve movements between terminals. • Modes assembly and distribution: • Cannot travel individually, but in batches. • People have to go to bus terminals and airports first to reach their final destinations. • Freight has to be consolidated at a port or a rail yard before onward shipment. • Terminals are essential links in transportation chains.
1. The Nature of Transport Terminals • Definition • Any location where freight and passengers either originates, terminates, or is handled in the transportation process. • Central and intermediate locations: • Points of interchange within the same modal system. • Insure a continuity of the flows. • Particularly the case for modern air and port operations. • Require specific facilities to accommodate the traffic they handle. • Points of interchange: within the same mode. • Points of transfer: between modes.
1. The Nature of Transport Terminals • Location • Serve a large concentration of population and/or industrial activities. • Specific terminals have specific locational constraints. • New transport terminals tend to be located outside central areas to avoid high land costs and congestion. • Convergence • Obligatory points of passage. • Invested on their geographical location which is generally intermediate to commercial flows. • Created by the centrality or the intermediacy of their respective locations.
1. The Nature of Transport Terminals • Accessibility • Accessibility to other terminals (at the local, regional and global scale). • How well the terminal is linked to the regional transport system. • Infrastructure • Handle and transship freight or passengers. • Must accommodate current traffic and anticipate future trends. • Modern terminal infrastructures consequently require massive investments.

2. Passengers Terminals • Overview • Passenger terminals require relatively little specific equipment. • Simple structures. • Basic amenities (waiting areas, ticket counters, food services). • Airports • Are the exception. • The most complex terminals. • Passengers may spend several hours in the terminal. • Transiting, check-in and security checks, baggage pick up and customs and immigration on international arrivals. • Wide range of services. • Provide the very specific needs of the aircraft.
3. Freight Terminals • Specialized entities • Specific loading and unloading equipment. • Wide range of handling gear is required. • Differentiated functionally both by the mode involved and the commodities transferred. • Distinction by two major types of cargo • Bulk: • Goods that are handled in large quantities, that are unpackaged and are available in uniform dimensions. • Liquid bulk goods: Pumps to move the product along hoses and pipes; limited handling equipment is needed, but significant storage facilities may be required. • Dry bulk: wide range of products, such as ores, coal and cereals; handling equipment is required; utilize specialized grabs and cranes and conveyer-belt systems.
3. Freight Terminals • General cargo: • Goods that are of many shapes, dimensions and weights such as machinery and parts. • Because the goods are so uneven and irregular, handling is difficult to mechanize. • General cargo handling usually requires a lot of manpower. • Warehousing • Assembling the individual bundles of goods: • Time-consuming and storage may be required. • Need for terminals to be equipped with specialized infrastructures: • Grain silos, storage tanks, and refrigerated warehouses, or simply space to stockpile.
4. Terminal Costs • Terminal costs • An important component of transport costs. • Infrastructure costs: • Construction and maintenance costs. • Facilities such as piers, runways, cranes and structures. • Transshipment costs: • Composing, handling and decomposing passengers or freight. • Labor requirement of terminal facilities. • Administration costs: • Managed by institutions such as port or airport authorities or by private companies.

B – Ports and Rail Terminals • 1. Port Sites • 2. Port Functions • 3. Rail Terminals
1. Port Sites • Ports • Convergence between two domains of freight circulation: • Land and maritime domains. • Facilitates convergence between land transport and maritime systems. • Handle the largest amounts of freight, more than any other types of terminals combined. • Infrastructures to accommodate transshipment activities. • Administration: • Submitted to authorities. • Regulating infrastructure investments, its organization and development and its relationships with customers using its services.

1. Port Sites • Port sites • Maritime access: • Physical capacity of the site to accommodate ship operations. • Tidal range: difference between the high and low tide. Ship operations cannot handle variations of more than 3 meters. • Channel and berth depths: very important to accommodate modern cargo ships. • Panamax ship (65,000 deadweight tons) requires more than 12 meters (40 feet) of depth. • Many port sites are unable to handle modern maritime access. • Maritime interface: • Amount of space that is available to support maritime access. • Related to the amount of shoreline. • Guarantee its future development and expansion.
1. Port Sites • Infrastructures: • Must have infrastructures such as piers, cranes and warehouses. • Infrastructures consume land which must be available to insure port expansion. • Land access: • Access from the port to industrial complexes and markets. • Requires efficient inland distribution systems, such as fluvial, rail (mainly for containers) and road transportation.

1. Port Sites • Port development • Setting: • Dependent on geographical considerations. • Furthest point of inland navigation by sailships. • Fishing port with trading and shipbuilding activities. • Simple terminal facilities. • Warehousing and wholesaling, adjacent to the port. • Expansion: • The industrial revolution triggered several changes on port activities. • Quays were expanded and jetties were constructed to handle the growing amounts of freight and passengers as well as larger ships). • Shipbuilding became an activity that required the construction of docks. • Integration of rail lines with port terminals. • Port-related activities expanded to include industrial activities. • Expansion mainly occurred downstream.
1. Port Sites • Specialization: • Construction of specialized piers to handle freight such as containers, ores, grain, petroleum and coal. • Expansion of warehousing needs. • Larger high-capacity ships often required dredging or the construction of long jetties granting access to greater depths. • Downstream migration. • Original port sites became obsolete and were abandoned. • Reconversion opportunities of port facilities to other uses (waterfront parks, housing and commercial developments).

2. Port Functions • Main functions • Supply services to freight (warehousing, transshipment, etc.). • Supply services to ships (piers, refueling, repairs, etc.). • Concomitantly a maritime and land terminal. • Regional in their dynamics. • Hong Kong: • Natural site. • Geographical position of a transit harbor for southern China. • Singapore: • Outlet of the strategic Strait of Malacca. • Convergence of Southeast Asian transportation. • New York: • Gateway of the North American Midwest. • Hudson / Erie canal system.

2. Port Functions • Problems related to port infrastructures • Ports along rivers are continuously facing dredging problems. • Width of rivers is strongly limiting capacity: • Rarely a port along a river has the capacity to handle Post Panamax ships. • Lateral spread of infrastructures (Seaports). • Congestion in central areas. • Port / city competition for land (waterfront development).
3. Rail Terminals • Location • Not as space-extensive as airports and ports. • Suffer less from site constraints: • Many established prior to the Second World War. • Cities were more compact and land acquisition was easier. • Passengers and freight terminals: • Different locations. • Central railway stations: • Feature of most cities and tend to be located in downtown areas. • Key elements of urban centrality and activity. • Freight rail stations: • Consume more space. • Tend to be located at the periphery. • Older yards tend to be located at the margin of CBDs.
C – Airport Terminals • 1. Airport Sites • 2. Airport Functions
1. Airport Sites • Concept • Airports act as the main technical support of air transport. • Increased pressures on terminals: • Existing terminals have been expanded and new terminals have been constructed. • Replace airports no longer able to cope with the increased traffic. • International / Regional: • Role and function in the international and regional urban system. • Centrality (being an origin and destination of air traffic) and intermediacy (a hub or a gateway between destinations). • Local: • Level of accessibility of the airport over the metropolitan area it services. • Daily flows of planes, passengers, freight to and from the airport's terminals.
Geographical Scales of Airport Location International / Regional Local
1. Airport Sites • Local site requirements. • Airfields: • Runways and parking areas. • Long enough to accommodate the takeoff and landing of commercial planes. • About 3,300 meters (10,000 feet) are required for a 747 to takeoff. • Slope (less 1%), altitude and meteorological conditions. • About 32 movements (landings and takeoffs) per hour are possible on a commercial runway under optimal conditions. • Terminals: • Freight and passenger transit infrastructures. • Infrastructures for plane accommodation. • Linked with local transport systems.

1. Airport Sites • Land requirements • Land required by modern airport operations is considerable: • Landing and take off of planes. • Buffer between the adjacent urban areas to limit the noise generated. • Parking areas in airports located in car dependent cities. • Peripheral sites: • Sufficient quantities of land available. • The more recently an airport was constructed, the more likely this airport is to be located far from the city center. • Expansion and relocation: • Extremely difficult. • Most airports have grown at locations chosen in the 1950s and 1960s. • Most airports are now surrounded. • Only sites available are far from the urban core.
