Radial line
A radial line , similar to the diameter line , sometimes also called a radius line , connects suburbs with the local or city center and ends there in local public transport . A classic area of application are longer regional or overland lines with travel times of over 30 minutes or Metrobus lines in large cities . Today they are often advertised with regionally easily memorable brand names, for example terms typical of the landscape (“Der Leineweber” or “Edertalbahn”). From an operational point of view, such lines can be combined with other well-established lines to form diameter lines.
Radial lines can also help to design clear line networks , for example star-shaped city bus networks with their own line names for each individual line branch. This has the disadvantage, however, that all of the central bus stops following the bus meeting point can only be reached by changing trains. Even line connections that are clearly marked in routes and timetables , where two radial lines are then connected to form a diameter line, cannot counteract a loss of orientation and time, as well as the excessive effort for passengers with only short journeys.
A radial line requires a turning facility at the end of the line (e.g. in the city center) and sometimes an operating stop (to comply with driver rest times or the timetable).
In Austria , a street that connects the inner city with the outskirts is called a radial line ( entry and exit road ).
