According to the line hierarchy the timetable in PuT in Visum is set up hierarchically. The line route contains the information on the location, the time profile accounts for relative time specifications and the vehicle journeys and their vehicle journey sections provide valid day, departure time and the traversed sections of the line route. All four object types together make up the timetable, therefore the information, where and when PuT vehicle journeys take place.
Alternatively, the public transport supply side can also be described through line routes, time profiles and a regular service per time profile (Headway-based assignment). In this case we are also talking about a timetable in Visum.
Due to this hierarchical structure of the timetable, is it possible to reuse the data for various similar vehicle journeys. Otherwise, the exact route in the network would have to be specified for each individual vehicle journey and all times entered. With the line hierarchy however, a regular headway can easily be defined by specifying the departure times, the time profile and the line route.
