Journeys API

This is a workspace for Journeys API which allows developers and clients to access public transport lines, routes, stops and schedules. All material on this page are draft material and subject to significant change.

Concept

Journeys API allows developers and clients to access following information via REST API

• Routes on which public transport services operate
• Lines, or in other words grouping of routes. For example Line 2, which runs from Rauhaniemi to Pyyninkintori in Tampere
• Journeys made by public transport vehicles on certain line and route at certain day and time
• Stops where public transport vehicles stop during their journeys

The API allows accessing these concepts as hierarchy of objects (see later) as well as performing searches.

API Entities

The API is built on top of NeTEx entity model (http://user47094.vs.easily.co.uk/netex/), from which the entities in this API are derived. Following picture outlines the entities and their relationships.

Route

ROUTE entity describes a path through (a road or a rail) network, which is used by a public transport service (such as bus or a tram). A ROUTE is made up of a sequence of ROUTE LINKS which split the route into "pieces". Each ROUTE LINK starts and stops on ROUTE POINTS which typically map to a certain place in city infrastructure (a road junction, stopping place or a point of interest). All ROUTE LINKS laid out into a sequence form up the ROUTE (the start ROUTE POINT of the first ROUTE LINK is the start of the ROUTE and the end ROUTE POINT of the last ROUTE LINK is the ending point of the ROUTE). Following picture is taken from Tampere "reittikartta" and outlines a ROUTE through Tampere.

Line

LINE entity is a grouping of ROUTES that is generally known to the public with a common name, such as "Line 2".
