Open data for developers (GTFS)

Here you will find the schedule and route data of the Lahti region public transport in GTFS format.

GTFS (General Transit Feed Specification) is the most commonly used format for specifying public transit schedules. A GTFS feed contains static transit information.

There are two types of GTFS feeds: ”google_transit” and ”exp_waltti”.

The ”google_transit” data is designed to be used by various passenger information services and applications.

The ”exp_waltti” data is created for ticketing and payment systems (includes more information on stop zones etc.).

The materials are updated every couple of months.

”google_transit” (Updated 10.11.2020, version 2.6.5)

”exp_waltti” (Updated 10.11.2020, version 3.0.7)
