Transport network

from Wikipedia, the free encyclopedia

The traffic network or transport network consists of the entirety of all systems on or below the surface of the earth on which the spatial movement of people and goods takes place. Transport networks are part of the transport infrastructure .

On topographic maps , the entirety of all railways , roads , paths and airfields with the associated structures is viewed as a transport network.

From a transport geographical point of view, the transport network consists of edges , junctions and the hinterland of the periphery . The junctions or centers are connected by the edges that receive the traffic flow. The hinterland or the periphery is supplied from the individual nodes. This division into edges and nodes makes it possible to simplify complex traffic networks and to investigate them with graph theory .

Examples

  • In transport networks for data traffic ( data network ), the edges are the providers and the nodes are the telecommunications networks .
  • In transport networks for electricity ( power grid ), edges are the long-distance lines and nodes are the switching stations and substations.
  • In transport networks for gas (gas network), the edges are pipelines and the nodes are compressor stations.
  • In transport networks for piece goods , the edges are the streets and the nodes are the transshipment points ( intermediate storage can also take place at the transshipment points )

Structure and direction

Short distances between the individual nodes can be a goal when setting up the transport network. Attempts can also be made to keep the construction and maintenance costs of the transport network as low as possible. Depending on what is desired, the result is a coarse or fine-meshed structure.

Transport networks can be directed in different ways. The transport can either only take place in one direction, e.g. B. for gas, oil and bulk goods. There are also transport networks with no preferred direction, such as B. for electricity and for piece goods.

optimization

In the transport industry, there are a wide variety of subtasks to maintain a transport network economically and to operate transports in this transport network.

  • In most transportation networks there is a hierarchy for the distribution of goods over long distances, such as sea ​​traffic from continent to continent, road traffic from city to city and finally distribution traffic from bin to bin.
  • Very carefully optimized transport networks carry traffic by various means of transport , such as by ship , by plane or by train and truck .
