Overview

CEN ISO/TS 18234-7:2013 (TPEG1‑PKI) defines the TPEG Parking Information Application (PKI) for delivering standardized parking information over multiple channels. It is part of the ISO/TS 18234 series for traffic and travel information (TTI) using the TPEG1 binary data format. The specification targets distribution via digital broadcasting and internet technologies, enabling parking data to be presented textually, voiced or graphically in navigation and ITS applications.

Key topics and technical requirements

• Application identification & framing: rules for identifying PKI as a TPEG1 service and the Service Component Frame used to encapsulate parking data.
• Message structure and components: standardized ParkingMessage with clearly defined subcomponents such as MessageManagement, ParkingLocation, ParkingSiteDescription, CurrentCapacity, ExpectedCapacity and Advice.
• Parking information tables: indexed vocabularies and lookup tables (e.g., VehicleType, ParkingType, UserType, FuelType, AvailableFeatures, Reservability, ParkingStatus, PaymentMethod, OpeningHoursType) to ensure consistent semantics and compact binary encoding.
• Binary encoding and data types: normative annexes define the binary SSF and data types, primitive and compound types, and syntactical representation for efficient TPEG1 binary streams.
• TPEG stream and MMC: specification of the TPEG data stream layout and the Message Management Container (MMC) for monolithic and multi-part message delivery.
• Design principles and toolkits: guidance on application-dependent data types, indexing, and toolkits for implementing PKI in receivers and back-end services.

Practical applications

• Real‑time parking availability and capacity updates displayed in in‑vehicle navigation systems, mobile trip‑planning apps and roadside information displays.
• Parking guidance systems that route drivers to available spaces, filter by vehicle type (e.g., EV, disabled), or show payment and opening hours.
• Integration into smart city platforms and traffic management centers to optimize parking utilization and reduce congestion.
• Broadcasting compact parking datasets over DAB/DAB+ or delivering richer PKI content via IP-based services (cellular, Wi‑Fi).

Who uses this standard

• ITS integrators, OEM navigation system developers and map/data providers.
• Broadcasters and content providers delivering TTI services.
• Parking operators, municipalities and smart‑city platform vendors.
• Mobile app developers and traffic management centers implementing parking guidance and analytics.

Related standards

• Other parts of the ISO/TS 18234 / CEN ISO/TS 18234 TPEG1 series (traffic & travel information applications and binary format specifications) - used together to implement full TTI services.

Keywords: TPEG1, TPEG1‑PKI, ISO/TS 18234‑7, parking information, intelligent transport systems, traffic and travel information, binary data format, parking capacity, parking guidance.

ISO/TS 18234-7:2013(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 18234-7 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 278, Road transport and traffic telematics, in collaboration with ISO Technical Committee
ISO/TC 204, Intelligent transport systems, in accordance with the Agreement on technical cooperation

Introduction
TPEG technology uses a byte-oriented data stream format, which may be carried on almost any digital bearer
with an appropriate adaptation layer. TPEG messages are delivered from service providers to end-users, and
are used to transfer information from the database of a service provider to a user’s equipment.
The brief history of TPEG technology development dates back to the European Broadcasting Union (EBU)
Broadcast Management Committee establishing the B/TPEG project group in autumn 1997 with the mandate
to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information in the
multimedia environment. TPEG technology, its applications and service features are designed to enable
travel-related messages to be coded, decoded, filtered and understood by humans (visually and/or audibly in
the user’s language) and by agent systems.
One year later in December 1998, the B/TPEG group produced its first EBU specifications. Two Technical
Specifications were released. ISO/TS 18234-2 (TPEG-SSF) described the Syntax, Semantics and Framing
Structure, which is used for all TPEG applications. ISO/TS 18234-4 (TPEG-RTM) described the first
application, for Road Traffic Messages.
Subsequently, CEN/TC 278/WG 4, in conjunction with ISO/TC 204, established a project group comprising the
members of B/TPEG and they have continued the work concurrently since March 1999. Since then two further
parts were developed to make the initial complete set of four parts, enabling the implementation of a
consistent service. ISO/TS 18234-3 describes the Service and Network Information Application, which should
be used by all service implementations to ensure appropriate referencing from one service source to another.
ISO/TS 18234-1 completes the series, by describing the other parts and their relationship; it also contains the
application IDs used within the other parts. Additionally, ISO/TS 18234-5, the Public Transport Information
Application (TPEG-PTI) and ISO/TS 18234-6 (TPEG-LRC), were developed.
This Technical Specification adds another powerful application to the ISO 18234-series allowing detailed
parking information to be encoded and transmitted to the user. This Technical Specification includes new
advanced message management and new datatypes, as specified in the annexes.
Today, traffic congestion has become a serious problem in urban areas. Some traffic congestion is attributed
to drivers searching for parking spaces. Therefore, timely provision of parking information could help ease
traffic congestion. Furthermore, parking information would be valuable for the visitor, particularly when it could
be used to signal where a temporary parking facility is established for a special occasion.
TPEG applications are developed using UML modelling and a software tool is used to automatically select
content which then populates this Technical Specification. Diagrammatic extracts from the model are used to
show the capability of the binary coding in place of lengthy text descriptions; the diagrams do not necessarily
include all relevant content possible.
This Technical Specification describes the binary data format of the on-air interface of the Parking Information
application, (TPEG-PKI) with the technical version number TPEG-PKI_1.0/001.

5 Application identification
The word 'application' is used in the TPEG specifications to describe specific subsets of the TPEG structure.
An application defines a limited vocabulary for a certain type of messages, for example parking information or
road traffic information. Each TPEG application is assigned a unique number, called the Application
Identification (AID). An AID is defined whenever a new application is developed and these are all listed in CEN
ISO/TS 18234-1.
The application identification number is used within the TPEG-SNI application to indicate how to process
TPEG content and facilitates the routing of information to the appropriate application decoder.
TPEG-PKI is assigned the AID = 0003 hex.

For example the name and the location of a parking site do not change frequently and thus this information
can be transmitted less frequently, unlike the number of available spaces. It is important none the less that the
basic information required to display a sensible message to the user should be sent in suitable intervals to
allow receivers just switched on to decode data within reasonable time.
Clients should decode messages with the same version number (and PartID in case of partial messages) only
once.
