ABSTRACT
The aim of this chapter is to create and present approaches and procedures for deriving prudent public timetables. These timetables and their compliance mirror the quality of the transit service provided. Hence, vehicles departing too early or ahead of schedule need to be restrained, just as those leaving late must be scheduled or rescheduled to be on time. Because of existing problems of transit reliability, there is need to improve the correspondence of vehicle-departure times with passenger demand instead of assuming that passengers will adjust themselves to given time-tables (excluding situations characterized by short headways). The following riddle may shed some light on the substance of adequate, and accurate, timetables.
