A transport network, or transportation network, is a network or graph in geographic space, describing an infrastructure that permits and constrains movement or flow. [1] Examples include but are not limited to road networks , railways , air routes , pipelines , aqueducts , and power lines .
English: Bedforms formed in sand in channels under unidirectional flow. Numbers correspond broadly to increasing flow regime, i.e., increasing water flow velocity. Blue arrows show schematically flow lines in the water above the bed.
An alternative to, and in many ways the precursor of the road map, was the itinerarium, a listing of towns and other stops, with intervening distances.The Tabula Peutingeriana, mentioned above, is in effect an itinerarium in visual form, offering routes and distances with little geographical accuracy.
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 ...
Speed – flow diagrams are used to determine the speed at which the optimum flow occurs. There are currently two shapes of the speed-flow curve. The speed-flow curve also consists of two branches, the free flow and congested branches. The diagram is not a function, allowing the flow variable to exist at two different speeds.
Straight-line diagrams were historically used in transportation planning but have been supplanted for these purposes by geographic information systems. [ 1 ] A strip map is a road map laid out similarly to a straight-line diagram, featuring the same details found in more conventional road maps rather than technical details.
Most important task of the board, among few others, is to conduct the SSC for 10th class and HSC for 12th class examinations. [2] It is the most popular education board in terms of enrollment in high school in India only after the Central Board of Secondary Education.
A transit map is a topological map in the form of a schematic diagram used to illustrate the routes and stations within a public transport system—whether this be bus, tram, rapid transit, commuter rail or ferry routes. Metro maps, subway maps, or tube maps of metropolitan railways are some common examples.
