Introduction
TC204 Intelligent Transport Systems, WG8, Public Transport and Emergency Services, have been
discussing enhancement of surface public transport information provision to surface public transport
users including international travellers around the world by using ITS technology.
WG8, Public Transport and Emergency Services, have been trying to harmonize current surface public
transport information provision interface national and regional standards, mainly, the TRANSMODEL
standard developed by CEN and the TCIP standard developed by the American Public Transportation
Association in the USA. However, because these surface public transport information standards are
widely accepted and used for system implementation in their regions, there is no perceived need or
demand to harmonize them.
Because WG8’s responsibility is to make surface public transport more convenient by realizing stress-
free surface public transport user information provision, WG8 has reached the conclusion that it has
to establish one International Standard (but not a technical report which has no binding rules) which
is defining basic framework that will fit above current national and regional standards. The accepted
national and regional standards (at this point in time, TCIP and TRANSMODEL) will be allowed to define
the specific information interfaces such as data format, stop point numbering system, etc. that are
necessary to the implementation of surface public transport information systems.
This part of ISO 17185 will be beneficial for all ISO/CEN member countries, as well as non-ISO/CEN
member countries, because this part of ISO 17185 will be a valuable “text book” to detail basic framework,
as well as highlight and encourage use of currently available national and regional standards such as
TRANSMODEL, TCIP, and possibly others. The intention is that, by deploying these national and regional
standards by other countries or regions, duplication of cost and time is avoidable. For those countries
that do not have surface public transport information standards, this approach allows more rapid
development and deployment of public transport systems that enhance usability and convenience.
This part of ISO 17185 is specifically set at a higher level and not aiming to harmonize currently
available national and regional standards to allow the use of these robust standards which are set at
various levels (for example, implementation specifications versus application level standards) but which
also experience widespread acceptance in their regional standards. This part of ISO 17185 intends to
establish a basic solid foundation for surface public transport user information provision framework and
is specifically limited to this scope to avoid conflict with those currently available regional standards.
This part of ISO 17185 is intended to be fully consistent with those currently available national and
regional standards which might be related to international surface public transport. In fact, in the
case of international surface public transport, surface public transport operators already have
transport-related information systems. However, it is not often the case that surface public transport
users, including international travellers, are provided with static and real-time information including
bus/train/tram locations appropriately and timely. This part of ISO 17185, and its scope and approach,
will solve this issue by setting basic framework for surface public transport information provision while
embracing existing national and regional standards.

INTERNATIONAL STANDARD ISO 17185-1:2014(E)
Intelligent transport systems — Public transport user
information —
Part 1:
Standards framework for public information systems
1 Scope
This part of ISO 17185 defines the framework for the realization of efficient public transport user
information provision to surface public transport users including international worldwide travellers.
In the surface public transport user information provision area, a set of regional and national standards
have already been established by related regional and national standardizing bodies.
This part of ISO 17185 defines basic framework for user information provision for surface public
transport users, from the viewpoint that the surface public transport users should be provided with
proper static and real-time information when it is most desired and effective. In order to realize the
desirable information provision, surface public transport information has to be efficiently gathered,
processed, and provided to surface public transport users in an appropriate way by using currently
available regional standards.
This part of ISO 17185 does not aim to define a new part of ISO 17185 that supersedes current regional
and national standards related to surface public transport. It aims to define the basic framework of
surface public transport user information provision by esteeming existing regional standards and
wisely using them.
This part of ISO 17185 does not aim to define specific information interfaces such as data format or a
stop point numbering system. The currently available regional standards established by regional and
national groups are suggested to be applied in that scope.

5 General Requirement
5.1 Importance of PT user information provision
PT service operator shall play an important role in surface transport as society fully depend upon
privately owned cars that has their own limitations such as high environmental impact, increasing
number of accidents related to aged drivers, and shrinking economy due to scattered population.
The issue of the current PT to be solved varies country to country or city to city, however, the following
common vision can be observed. From the PT service operator’s point of view, benefit/cost factor can

---------------------- Page: 9 ----------------------
ISO 17185-1:2014(E)

be kept high by deploying ITS technologies such as simple and efficient fare transaction device and
priority traffic control signal system. From the PT user’s (customer) point of view, PT use shall be more
attractive than driving his/her own car by improving PT transport speed and reducing PT fare and by
providing attractive PT user information to PT users.
When providing PT user information, it is important to understand that there are various types of
customers and their needs vary between customer types. In local residents, there are two types of
customers, one who does not know how to use PT and the the other who knows basic information and
understands that PT is reliable transport that is on time and safe. Usually, a visitor is not familiar with
local PT and expects physically and mentally friendly PT services. Therefore, PT user information
provision framework shall be designed to accommodate those various needs.
Various PT information provision projects are under practical use, and the project status reports
are commonly shared internationally to improve PT user information provision system continuously
throughout the world.
There are several key issues concerning PT when creating “PT user”-friendly society, namely,
— attractive PT user information provision to potential PT users,
— attractive PT IC fare card system,
— efficient and attractive PT service timetabling and service routes,
— fare relationship between regional transit regulator and PT service operator, and
— reliable relationship between PT drivers and PT service operator by deploying ITS technologies.
Defining basic PT user information provision framework, which is commonly acceptable internationally,
is indispensable for both of advanced and emerging countries where PT user information provision
system improvements are needed.
The PT user information provision service architecture and required standards needed varies country
to country. This part of ISO 17185 provides basic framework guidelines which shall be referred when
such PT information provision system is implemented.
This part of ISO 17185 describes high-level basic framework requirements for PT user information
provisions. For the detailed use cases and data and interface standards catalogues and cross reference,
refer to ISO 17185-2 and ISO 17185-3.
5.2 Roles of PT user information
The functional roles of PT user information are summarized as follows. Although the scope of this
part of ISO 17185 is PT user information provisions, all of the potential roles are listed for the reader’s
educational purposes.
— provide PT services using PT vehicles (track vehicles)
— provide planned service information
— provide passenger facility/infrastructure information
— provide real-time service information
— provide topographic and geographic information
— provide PT network information
— provide trip plans to customers
— provide information about disruptions to PT service
— detours

ISO 17185-1:2014(E)

— delays
— incidents
— provide (coordinated) transfer information (real-time, schedule)
— create data (data provider)
— collect data (e.g. asset information)
— process data (data processor)
— provide predictions
— translate data from one format to another/ or from one channel to another
— collate data (data collator)
— disseminate data
— validate data
— apply data to application
— fund information provision
— measure performance
— interface to other modes of transport
— integration of PT costumer information into intermodal travel planners
— other areas such as information use, access, service performance, quality, etc. can be added to this
list.
5.3 Objectives of this standard
The objectives of ISO 17185 are defined as follows:
— Part 1 defines the high-level stakeholder roles and responsibilities and their PT user information
exchanges.
— Part 2 defines data interface message comparison.
— Part 3 defines use cases for journey planning systems and their inter-operation where in the
worldwide standards apply and it may include exchange of information using nomadic devices.
Overall, this part of ISO 17185 describes a framework to facilitate inter-operability of public transport-
related information using different national/regional standards (The off-the-shelf use of standards).
This is accomplished by defining the high-level stakeholder roles and responsibilities and PT user
information exchange, data, and interface message comparisons use cases.
5.4 High-level use cases
In this part of ISO 17185, the high-level use cases are defined to describe commonly applicable
basic framework. The detailed use cases and translation between existing standards are defined in
ISO 17185-2 and ISO 17185-3. For the basic actors of these high-level use cases, see 5.5.

ISO 17185-1:2014(E)

5.4.1 Use case 1 - PT service operator to monitor, control, and inform customer and provide it
to information provider (regional)
This aggregate function is commonly known as automatic vehicle location and real-time passenger
information (AVL-RTPI). It has two functionalities: automatic vehicle location and passenger information.
The aim of AVL is to continuously adapt public transport services to circumstances on the ground. AVL
is taken into account by a key internal actor, which is the controller (an internal actor that appears in
the model through its function). It has two functions: monitoring public transport and controlling public
transport. The term “passenger information” here is limited to immediate information on the functioning
of public transport services. Passenger information is limited to the production of information aimed at
passengers; the delivery of this information is dealt by “Disseminate operating data” function.
5.4.2 Use case 2 - PT service operator to organize and plan public transport services
This aggregate function manages basic data, plans, and organizes the production of services and
manages and maintains resources.
5.4.3 Use case 3 - PT service operator to manage human and physical resources
This aggregate function is responsible for the centralized management of human and physical resources,
as opposed to “local management”, which is carried out in vehicle depots and crew facilities. It is
comprised of two independent components: central management of personnel and central management
of rolling stock.
5.4.4 Use case 4 - PT service operator to organize shared services
This aggregate function enables the planning and organization of shared services, ranging from public
transport to shared vehicle management such as private initiative carpooling.
5.4.5 Use case 5 - Information provider (regional) to get information from PT service operator
and inform customer (transport user)
This aggregate function enables the provision of aggregated information of single- or multi-service
operators to the customer and enables the value-added service to the customer for them to plan efficient
public transport use.
5.4.6 Use case 6 - Inter-regional information provider to get information from information pro-
vider (regional) and inform customer (transport user)
This aggregate function enables the provision of aggregated information of single or multiple regional
PT information to the customer and enables the inter-regional information provider to provide value-
added inter-regional PT information to the inter-regional transport user such as worldwide traveller for
them to plan efficient inter-regional public transport use.
5.4.7 Use case 7 - Transport regulator to regulate PT service operator
This is a function responsible by or under national law or regulation, enforcement of laws, administrative
provision, and international agreements with respect to traffic and transport.
5.4.8 Use case 8 - Transport authority to plan, finance, tender, and contract PT services
This aggregate function enables transport authorities plan, finance, tender, and contract PT services.
The PT operators provide scheduling and real-time information to the transport authority as arranged
in the contract. The transport authorities declare common standards for data exchange and provide
complete and up-to-date PT user information.
