Regular interval timetable in Hungary
Public transport in the Central Eastern region of Europe currently faces a situation very similar to Western European experiences from the 1970s onwards. Yet this current ` curse ` can be considered as a ` blessing ` as we are now in a position to select, as a point of depart towards progress, the most suitable, tried and tested method from among a number of approaches. A modern, intermodal timetable structure relies on three basic factors: the periodicity, the symmetry and the everywhere-to-everywhere connection system at the network nodes. In the first part, the paper presents the economic principles; afterwards it defines the role of these factors in an integrated timetable structure and presents the standard values for the parameters used in the united European timetable structure.
