Public transport - Distribution APIs for MaaS
Existing public and private distribution API specifications will be identified, where practicable, and summarised in a number of ways, including: ownership of specification, scope of API functionality, basis of data model and data categorisation used, management of reference data, commercial access rules to the specification, governance of the specification, existing examples of use for MaaS booking, coherence with existing CEN standards, potential for becoming a new CEN standard.

Introduction
Mobility-as-a-Service (MaaS) is a concept that was created in the Nordics and in Austria several years
ago. The original idea was quite straightforward: allow any traveller to go seamlessly from A to B using
only one single mobile application and based on his/her personal preferences. As technology has evolved
and as travellers were experimenting with new types of services (eg, free-floating shared scooters), it
seemed that the term MaaS was used to cover a very wide range of realities. To make this document
clearer, here MaaS will be considered in its original definition and parameters: one single mobile
application that allows any traveller to search, plan, book, pay, and travel (with support when needed)
from A to B using at least one modality with the operations side invisible to the eye; the above-mentioned
actions not being necessarily logically linear nor unique.
MaaS operations, based on MaaS apps, conventionally start with journey planning systems that use
timetables (eg CEN OJP). Sometimes fares are used as well. There are well-established standards for the
exchange of this data, such as GTFS and Transmodel/NeTEx for Public Transit. In the EU, there are legal
obligations on many transport operators to make such data available using the Transmodel/NeTEx
standards. These standards are managed by a CEN (the European Standards body) working group (TC
CEN/278/WG 3 Public Transport).
The next stage in full MaaS development is the ability to check availability, to make bookings, to take
payment, to get tickets for travel, etc, for both conventional public transport modes and newer forms of
mobility services. A key aspect is the separation of task and responsibilities of the MaaS Provider in
arranging the trip and transport service operators to execute the trip. MaaS Providers will normally use
APIs to access transport operator booking systems and carry out these functions. In this work, these
transactional APIs are referred to as distribution APIs. The term is taken from the Global Distribution
Systems that distribute the sale of multi-modal transport products from a wide range of transport
operators directly to the customer. APIs for air and rail have existed for years, but have more recently
been extended for shared mobility and urban modes such as metro and bus.
Standardization of these distribution APIs is helpful to be able to integrate different types of transport
operators into one single mobile application. Therefore, in Europe, as part of the Multimodal Digital
Mobile Services (MDMS) project, the European Commission is considering whether to choose one or
more sets of distribution APIs to add to its regulatory regime. An impact assessment will start Q1 of 2022
with regulatory proposals expected in Q4 2022. If there are to be more harmonized standards, it is likely
that these will be managed by the same CEN working group that manages Transmodel/NeTEx. In order
to provide an up-to-date view on what already exists worldwide in terms of distribution APIs, a CEN
project team has undertaken a survey. From the responses received, it has prepared this state-of-the-art
technical report that lists API sets and provides some basic information about each of them.
Policy in relation to distribution APIs for MaaS is clearly topical and during the work of the project several
other European and national initiatives on the same topic came to light.
1 Scope
1.1 MaaS distribution API survey
This document describes the execution and results of a survey into distribution APIs for MaaS. API
owners have been encouraged to participate if they offer APIs that support the functions or if they were
expecting to do so within a reasonable timeframe. Although there seems to be good coverage of European
examples, survey responses cannot be treated as representative of the complete worldwide set of APIs,
but provide strong indications of the totality of what exists, and the issues raised in terms of
standardization and regulation.
The survey has been carried out without any pre-determined agenda in terms of API policy or strategy.
It has not been assumed a priori that a single API set could or should meet all multi-modal business needs.
Comments are provided in respect of the impacts in standardization, but it was not considered
appropriate to make any comments on regulatory implications, as this is not the area of competence for
the CEN working group.
1.2 Transport distribution functions
Distribution APIs may be related to one or to a combination of the functionality/ies (processes)

corresponding to the chosen trip option and held by a transport authority or other entity
to the related pricing rules
Support: providing help to user during Management of unforeseen events during the
travelling by different means journey, for example schedule disruption,
