                                                         Tip: Alternatively, you can create multiple time intervals with the same duration (Creating multiple time intervals of identical length).  |

                                                         Note: For a timetable-based assignment, you can refine the intervals by dividing them into time spans of equal length (homogeneous distribution of OD demand) (Timetable-based assignment: Basis page).  |
