GTFS-Fares v2
Issue - the previous fares features in GTFS (Fares v1)
can only represent simple fare structures
Goal - Riders can get accurate pricing information and choose
from a comprehensive range of options, including various
passes, fare media, and rider categories within different faresystems
GTFS-Fares v2 aims to model more complex fare structures
It is currently being developed iteratively
4GTFS-Fares v2
Have adopted:

Working on:

Simple zone-based fares

Priority of matchingrule between a leg
and multiple products

Fare media

Improve mechanisms
for multi-legs journey.

Next:
Improve zone-based
fares

Future:Rider categoryFare Capping

Time-based fares

Distance-based fares

Route-based fares(networks)

Inter-agency fares
and more…

DRT works in standalone app/website/service
Riders are not aware of DRT options

Riders discover DRT services through trip planners
Provide integrated routing options for both ﬁxed-route andDRT services

Not include - actual path, realtime info, “accurate” time
duration, and transactional info

ZonesThe vehicle can pickup/dropoff
riders anywhere within a zone
or between zones to serve
demand-responsive requests

Example: TURE TRANSIT (MN, US)

Point-to-point
The vehicle can pickup/dropoffriders at a certain point(orgroup of points) to serve
demand-responsive requests

Image source: ﬁnd-a-ride

Example: Flims Laax Falera Nightliner (CH)8

Route Deviation
Fixed-route services where thevehicle can deviate to serve
demand-responsive requests
within a zone around the path

Example: SMART (MN, US)

GTFS features
As GTFS is growing, it is becoming increasingly hard tounderstand what can be represented with GTFS.

●

Easier to know what’s possible to represent with GTFS●

Consumers and vendors can share with the community
the list of features they support in an efﬁcient way●Tracking the production of feature on the Mobility
Database using the Canonical GTFS Validator●Allow organizations to require certain features

Improve GTFS governance process●

High barrier to entry●

Insufﬁcient engagement in the proposals in the earlystages of development.

●First adopters are frequently impacted bylast-minute changes to their implementation,leading to an increase in committed resources.

Improve GTFS governance process

Phase 1 - Effective
communication andGitHub management●

Publication of amonthly “GTFS Digest”●

Using GitHub issue
templates and labels

Phase 2 - Enhancing
voting and reviews●●

Adding an earlier voteto increase the visibility
and potential issues ofa proposal early-on
Incorporating review
guidelines

Phase 3 - Fast track
process for smallerchanges●

Adding a lightweightprocess for smallerchanges●

Other editorial changes
on the spec amendment
