By default, GTFS-to-HTML attempts to generate a timetable for each route and direction present in a GTFS file. However, much greater control over which routes, directions and days of the week should be built into timetables is possible by adding some additional, non-standard .txt files to an agencies GTFS.
- timetables.txt - Specifies which HTML timetables should be built based on route_id, direction_id, days of the week and a date range.
- timetable_stop_order.txt - Specifies the stop order that should be used for timetables.
- timetable_pages.txt - Specifies which HTML timetables should be grouped together into a single HTML page.
- stop_attributes.txt - Specifies additional information about a stop.
