Changelog

• 0.1.0: initial commit; Technical Memo Documentation
• 0.2.0: added additional required fields to transfers_ft.txt in order to support route-specific transfers and time-point precedence. Technical Memo Documentation
• 0.2.1: changed time to be specified as HH:MM:SS from midnight instead of HH:MM:SS to be consistent with GTFS
• 0.2.2: updated file names that are not GTFS to ALL have _ft extension.
• 0.2.3: added optional file bike_access_ft.txt
• 0.2.4: decreased ambiguity in transfers_ft.txt and changed fields related to schedule creation to be optional.
• 0.2.5: consolidated knr_ft.txt and pnr_ft.txt into drive_access_points_ft.txt
• 0.2.6: make costs in consistent values across the specification, as defined in fare_attributes_ft.md. Fixes link to fare_attributes_ft.txt.
• 0.2.7: eliminates fare_class as an optional variable in routes_ft.txt to eliminate ambiguity
• 0.2.8: requires transfers_ft because it has distance. Blank schedule_precedence is no precedence either way. Defaults times in fare_rules_ft can have label default.
• 0.2.9: many clarifications. Use lot_lon rather than lot_long in drive_access_points_ft for GTFS consistency.
• 0.3.0: clarifications. Changed definition of end_time. Renamed fare_class to fare_period. Made optional files optional.
•  0.4.0: Adds dwell time formulas and variables needed to calculate dwell time based on the Transit Capacity and Quality of Service Manual .
• 0.4.1: Updates vehicles_md descriptions to clarify dwell time defaults and blanks.

Specification

A GTFS-PLUS transit network consists of required and optional data files that together describe a network of transit service. Files not denoted with _ft follow the same format as the General Transit Feed Specification - GTFS.

A GTFS-PLUS transit network MUST include the following files:

Filename	Description
walk_access_ft.txt	walk access links
transfers.txt	transfer links
transfers_ft.txt	additional transit link information
trips.txt	transit vehicle trips
trips_ft.txt	additional transit vehicle trip information
routes.txt	transit routes
routes_ft.txt	additional transit route information
stops.txt	transit stops and stations
stop_times.txt	transit trip stop times
vehicles_ft.txt	transit vehicles
agency.txt	transit agency
calendar.txt	transit schedule calendar

A GTFS-PLUS transit network MAY include the following files:

Filename	Description
drive_access_ft.txt	drive access links
bike_access_ft.txt	bike access links
drive_access_points_ft.txt	park and ride access links; must be included if provide drive access links.
shapes.txt	transit route shape points
stops_ft.txt	additional transit stop and station information
stop_times_ft.txt	additional transit trip stop time information
fare_attributes.txt	fare attributes (see note below)
fare_attributes_ft.txt	fare attributes (see note below)
fare_rules.txt	fare rules
fare_periods_ft.txt	additional fare rules
fare_transfer_rules_ft.txt	fare transfer rules
zones_ft.txt	zone locations

Note: fare_attributes_ft.txt is an extended version of the optional GTFS file fare_attributes.txt that allows for representation of time-of-day pricing (e.g., peak surcharges). Both files are documented here in this repository for completeness, but only one of the two is needed for a given implementation of GTFS-PLUS.
