Abstract

In this paper we propose the concept of entropy of the timetable to evaluate the mass transit system. This concept simplifies the problem of the synchronisation of the timetable. Additionally, we show how to use the concept of the entropy for evaluation. We first describe the importance of the synchronised periodic railway timetable, and also the conditions for the synchronisation of the timetable.We next present a difficulty encountered when we synchronise the timetable completely everywhere in the transit network. This difficulty is attributed to the restriction of train headway in the synchronisation of the timetable. Then we must simplify the problem of synchronisation of the timetable by removing some constraints. Lastly, we indicate that using the concept of the entropy is useful for solving the complex problem.
