With timetable-based assignment, you can use departure or arrival time based time series for your demand segments. A departure time based time series expresses the departure time desired by demand. Analogously, an arrival time based time series expresses the arrival time desired by demand. This time reference is assigned to the demand segment in the Demand description. (User Manual: Selecting a time reference for demand segments).
This time reference allows you to look at the paths of certain user groups whilst also accounting for the constraints of the desired trip. Public transport to schools in the morning is a typical example of trips with a fixed arrival time, which in this case is defined by the time classes start. Students choose their connection based on the arrival time at their destination.
The time reference also influences the usability of a connection as well as the calculation of the parameters adaptation time and extended adaptation time (Temporal utility of a connection and Skims of time).
