Intelligent transport systems — Public transport user information — Part 3: Use cases for journey planning systems and their interoperation

ISO/TR 17185-3:2015 is to define high level general requirements of journey planning systems by standardizing use cases. This part of ISO 17185 defines basic requirements for implementing the journey planning system, from the viewpoint that the public transport users should be provided with convenient tool to make his or her journey more efficient ones. In order to realize the desirable journey planning system, public transport information has to be efficiently processed and provided to public transport users in an appropriate way by using currently available regional standards. This part of ISO 17185 does not standardize specific information interfaces such as data format or a stop point numbering system and so on but currently available regional standards established by regional and national groups are suggested to be applied. ISO 17185 is composed of the following parts: - Part 1: Standards framework for public information systems: (International Standard) - Part 2: Data and Interface standards catalogue and cross reference: (Technical Report) - Part 3: Use cases for journey planning systems and their inter-operation: (Technical Report)

Introduction
ISO/TC 204, Intelligent Transport Systems, has been discussing enhancement of surface public transport
information provision to surface public transport users including international travellers around the
world by using ITS technology.
The responsibility of ISO/TC 204 is make surface public transport more convenient by realizing stress-
free surface public transport user information provision, and hence, the technical committee has been
working to develop one set of international standard and several technical reports which are defining
basic framework and practical uses cases that will fit above current national and regional standards
as a reference. The accepted national and regional standards (at this point in time, such as 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 implementation of surface public transport
information systems.
The set of International Standard and Technical Reports will be beneficial for all ISO/CEN member
countries as well as non ISO/CEN member countries. The International Standard/Technical Reports will
be a valuable reference 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.
ISO 17185 is specifically set at a higher level, or reference and not aiming harmonize currently available
national and regional standards to allow 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 International Standard 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.
ISO 17185 is intended to be fully consistent with those currently available national and regional standards
which may be related to international public transport. In fact, in the case of international surface public
transport, public transport operators already have transport-related information systems. However,
public transport users, including international travellers, are often not provided with static and real time
information including bus/train/tram locations in an appropriate and timely manner. ISO 17185, and its
scope and approach, will solve this issue by setting basic framework for public transport information
provision while embracing existing national and regional standards.

5 General requirement
This part of ISO 17185 describes use cases for journey planning systems and their inter-operation of PT
user information provisions for PT users, the customers. For the detailed data and interface standards
catalogues and cross reference, which fits to those who do not have their own regional and national
standards, refer to ISO/TR 17185-2.
5.1 Importance of PT user information provision
PT service operator shall play an important role in surface transport as the society fully depend upon
privately-owned cars has its own limitation 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, but the following
common vision can be observed. From PT service operator view point, benefit/cost factor can be kept
high by deploying ITS technologies such as simple and efficient fare transaction device, priority traffic
control signal system, etc. From PT user, the customer, view point, PT use shall be more attractive than
driving his/her own cars by improving PT transport speed and reducing PT fare, and by providing
attractive PT user information to PT users, the customers.
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 resident, there are two types, one
who does not know how to use PT, the other who knows basic information and understands that PT is
reliable transport means in time and safety. Usually visitor is not familiar with local PT and convenient,
accessible and easy to use PT service and information. 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 user, the customers;
— attractive PT contactless card system;
— efficient and attractive PT service in timetabling and service route;
— good relationship between regional transit regulator and PT service operator;
— better relationship between PT driver and PT service operator by deploying ITS technologies.
Therefore, 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. This is the purpose of ISO 17185-1.
The PT user information provision service architecture and required standards needed varies country to
country and therefore, this international standard is not defining new rules but provide basic framework
guide lines which shall be referred when such PT information provision system is implemented.

ISO/TR 17185-3:2015(E)

This part of ISO 17185 describes detailed use cases of journey planning systems and their inter-operation.
For the detailed data and interface standards catalogues and cross reference, which fits to those who do
not have their own regional and national standards, refer to ISO/TR 17185-2.
5.2 Objectives of ISO 17185
The objectives of ISO 17185 are defined as follows.
Part 1: Define the high level stakeholder roles and responsibilities and their PT user information
exchanges.
Part 2: Define data interface message comparison.
Part 3: Define 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, in ISO 17185, it describes a framework to facilitate inter-operability of public transport-related
information using different national/regional standards, off the shelf of use of standards, help to guide
evolution of standards worldwide to a common framework, identify gaps in existing standards and
translate between existing standards to facilitate PT users including worldwide travellers.
This is accomplished through, definition of the high level stakeholder roles and responsibilities and PT
user information exchange, data and interface message comparisons, use cases wherein the worldwide
standards apply.
5.3 Roles and responsibilities of basic actors in journey planning system
As described in ISO 17185-1, the basic actors of PT journey planning system are shown in Figure 1 below.
In the basic PT JP (journey planning) system, four major basic actors are defined as shown in Figure 1.
This is shown as basic system framework as an example and at actual system implementation phase,
some of those actors shall be modified to fit to each countries service requirements and circumstances.

5.3.1 PT service operator
PT service operator is an entity who operates PT service and in the PT JP system, its function is to
provide accurate and up-to-date PT information, such as bus stop/station, vehicle location, scheduled
service, ticketing, fare, reservation status, payment status to PT JP service provider. The PT JP service
provider sends PT users seat reservation request to PT service operator and receives request results.

ISO/TR 17185-3:2015(E)

The PT USER access such information through PT JP service provider. This entity is composed of the
following sub actors:
a) transport service provider;
b) transport service manager;
c) transport operation manager.
For more details, refer to ISO 17185-1.
5.3.2 PT JP service provider
PT JP service provider is an entity who gathers single or multiple modes (such as bus, train, airplane,
tram, metro) and/or single or multiple PT service operators data and provide value added PT JP service
to PT user through internet for PC and mobile device and digital TV network. The PT JP service provider
for multimodal is often called multi-modal JP service provider. When data format is deferent from PT
service operator to PT service operator, data conversion function shall be added in the data line from PT
service operator(s).
Responsible for the provision of PT JP information services to PT users or others. Those services may
be including journey route search (such as bus stop/station, route, travel time, fares, mobility restricted
information), reservation status, payment status, schedules service, ticketing, vehicle location, etc. The
major communication link to PT user is currently done through internet with WEB service.
Administrator of PT JP service provider shall perform the system maintenance for updating the system
database and improving the services quality.
5.3.3 Data provider
Data provider is an entity who gathers multiple type of information, such as interchange information,
such as length and time of foot path between stop points, stairs, escalators, lifts, information for
challenged people (or people with big suite case, baby buggy, etc.), disruption information to escalators,
lifts, blockages of corridors, access to stop points, etc., graphs for calculating pedestrian (and optional
park and ride and cycle and ride) routes from and to the PT station, disruption information for the foot
path from and to the stations (plus optional park and ride, cycle and ride, cycle, etc.), addresses, POIs,
regional names, zoom able background maps for display. This actor may be private sector or municipal,
state, federal government body.
5.3.4 PT user
PT user is a human who use PT service. When a PT user provides geographical location data such as
GPS location data to PT JP service provider, the PT user can receive real time route navigation service
through mobile device such as smart phone. The PT user is responsible to plan/define journey plan, find
best transport route, re-plan journey when needed. In the use cases description defined in 5.4.4, it is
described as “user”.
5.4 Use cases description of journey planning system
The use case descriptions of the journey planning systems and their inter-operations shall be defined as
shown below. Use cases defined in ISO 17185 are described as informative purpose only and in the real
implementation of the journey planning systems, some of these use cases shall be modified to fit each PT
service requirements and circumstances.
These use cases described in this part of ISO 17185 do not preclude any “presentation layer” format such
as web, mobile web, interactive voice response (phone), or kiosk. A presentation layer represents user
interface capabilities as shown in Figure 2 below.
