Overview

ISO 13111-1:2017 - part of the Intelligent Transport Systems (ITS) family - defines general information and detailed use case definitions for using a personal ITS station (P‑ITS‑S) to provide and maintain ITS services for travellers (drivers, passengers and pedestrians). The standard covers scenarios for slow transport (walking, cycling, wheelchair), transfer and hub environments (stations, car parks, indoor transfer areas), multi‑modal traffic information, multi‑modal routing/re‑routing and real‑time guidance (voice/image/text/map), plus community activities like team travel.

Key topics and technical scope

• P‑ITS‑S role and configurations: architecture components, P‑ITS‑S configurations and interfaces with roadside (R‑ITS‑S), central (C‑ITS‑S) and vehicle ITS stations.
• Use case clusters and definitions: detailed use cases such as positioning requests, slow‑transport navigation, transfer/parking information, indoor navigation, trip planning, real‑time traffic and public transport updates, evacuation/emergency services, vehicle status access (P2V), location sharing and team travel.
• Application behaviour: static and dynamic multi‑modal routing, re‑routing, real‑time guidance presentation (voice/image/text/map) and data exchange patterns between personal stations and ITS infrastructure.
• Normative integration: aligns with related ITS protocols and information models (references include ISO/TR 13185, ISO 19132/19133/19134, ISO/TS 18234, ISO 14819 and SAE J2735), ensuring harmonised data exchange and interoperability.

Introduction
This document specifies the interface to support a variety of applications based on the personal ITS
station and data exchange between the stations being defined in the related standards or specifications
in TC 204 such as vehicle ITS station, central ITS station, roadside ITS station, etc.
Applications supporting ITS service provisions and multimedia use via the personal ITS station need
to harmonize with existing or developing standards or technical reports in the concerned areas. These
applications would be implemented using vehicle information, driver advisory, warning systems,
entertainment systems, traffic information, public transport information, slow transport system
(non-motorized travel) information and multi-modal navigation service based on the communication
architecture and protocol defined in ISO/TR 13185 and other related standards.
Besides ISO/TR 13185, the following standards are subject to analysis in regard to their applicability to
supporting ITS service provisions and multimedia use via personal ITS stations:
— ISO 14819 defines TTI messages via traffic message coding (RDS-TMC) using ALERT-C;
— ISO/TS 18234 and ISO/TS 24530 defines TTI via Transport Protocol Experts Group (TPEG);
— ISO 19132, ISO 19133 and ISO 19134 define the conceptual schema of location base service, tracking
and navigation service, and multi-modal navigation service;
— ISO 15031 defines emissions-related diagnostic data supported by vehicles in all countries requiring
OBD compliance;
— ISO 27145;
— ISO 22900-2 defines the Modular Vehicle Communication Interface (MVCI) D-PDU API to separate
the protocol data unit (PDU) from vehicle specific protocols;
— ISO 22901 defines the Open Diagnostic data eXchange (ODX) format which is an XML-based standard
for describing diagnostic related ECU data. This standard is becoming the vehicle manufacturer’s
choice to document vehicle system diagnostic data and protocol information;
— ISO 22902 is a multimedia and telematics standard based on AMI-C specifications and reference
documents for automotive industry. The important logical element of the architecture is a vehicle
interface;
— ISO 22837 defines the reference architecture for probe vehicle systems and a basic data framework
for probe data;
— ISO 29284 defines the standardization of information, communication and control systems in the
field of urban and rural surface transport, including intermodal and multimodal aspects thereof,
traveller information, traffic management, public transport, commercial transport, emergency
services and commercial services in the ITS field;
— SAE J2735 defines the support of interoperability among DSRC applications through the use of
standardized message sets, data frames and data elements.
This document defines the personal ITS stations applications such as public transport information
services, slow transport (non-motorized travel as bicycle and walking) information service, multi-
modal navigation services, etc.

5 Document overview and structure
This document set provides the application requirements to support the implementation of the personal
ITS station in accordance with the related standard.
— ISO 13111-1
This document provides an overview of the document set and structure along with the use case
definitions and a common set of resources (definitions, references) for use by all subsequent parts.
— ISO 13111-2
This document specifies data exchange schema between personal ITS station and the other stations.
We shall reflect the general requirements derived from the use cases as specified in ISO 13111-1.
Because it is difficult to enumerate specific details of the protocol for all sorts of application, ISO 13111-2
only defines the general protocol.
If there are more specific and more complete descriptions of the details of the protocol based on the
specific implementing application, we shall submit a new work item proposal.

For example, in protocol requirements and specifications for personal ITS station in the case of transfer
service in the integrated transport hub, we shall propose a new standard work item that consistent
with the general schema defined in ISO 13111-2.

6 Architecture components and P-ITS-S configuration
6.1 ITS communication architecture components
The ITS communication architecture is a communication system designed for ITS and made of four
physically separated subsystem components:
— the vehicle subsystem component (Vehicle Station);
— the personal subsystem component (Personal Station),
— the roadside subsystem component (Roadside Station),
— the central subsystem component (Central Station).
Each of the four components described in Figure 2 contains the ITS subsystem components and usually
a vehicle gateway connecting the ITS Station to a legacy system. The vehicle shall require a vehicle
gateway connected to the vehicle station and to the vehicle manufacturer’s proprietary vehicle network
which is defined in ISO 13185.
Figure 2 illustrates the communication system designed for ITS.
a) Personal-ITS-Station – personal subsystem component.
b) Vehicle-ITS-Station – vehicle subsystem component connected to vehicle domain architecture
designed by vehicle manufacturer via the V-ITS-SG.
c) Roadside-ITS-Station – roadside subsystem component.
d) Central-ITS-Station – central subsystem component.
Figure 2 — ITS communication architecture
Figure 3 illustrates the connection between the personal and the other ITS station through the ITS
stations router which support the CALM architecture.
Figure 3 — Connection between P-ITS-S and the other ITS-S based on CALM architecture
There are many existing International Standards for the communication between the vehicle station
and personal station for bi-directional vehicle data transfer.
It is necessary to review and determine the suitability of the existing International Standards for
nomadic devices and existing vehicle communication network access standards.
6.2 Overview of application scenario
This document shall specifies use cases and requirements for provision of the ITS services based on the
Personal-ITS-Station connected to other stations.
Five types of schema are described for the application of a personal ITS station in Table 1.

NOTE 1  P2V: the available interaction or interoperation when a Personal Station connects to the Vehicle Station.
NOTE 2  P2R: access to a Roadside-ITS-Station by a Personal-ITS-Station where they connect to each other
directly.
NOTE 3  P2P: application between two Personal Stations.
NOTE 4  P2C: a Central Station interface for Personal Station to obtain all kinds of available ITS services.
NOTE 5  P2X: a P-ITS-S connects to the other station via a Central Station or access Central Station via the
other stations.
6.3 P-ITS-S configurations
Above the traffic information and vehicle information, the ITS service will be extended to support
slow transport systems to include peds and bikes, transfer node services, local transport networks,
emergency services, vision impaired and disabled services when a user with his P-ITS-S is far away
from the vehicle or even the road. These applications in ITS provisions are based on the connection to
the server platform of the Central Station. The communication configurations such as bluetooth, WiFi,
2-3G, FM and DAB/DVB are needed in the different application scenarios of the Personal Station.
The support for an open access method shall need to move from proprietary systems to a flexible,
standardized system. The XML-based vehicle data transfer protocol’s open access method
accommodates ISO standards depending on various applications like eCall, multimedia control, probe
data collection, diagnostics, etc.
In these application scenarios, a P-ITS-S consists of the positioning modular, communication modular,
application software and hardware. In some specific cases, the hardware of a P-ITS-S may include
several different connected devices and a gateway is used to support the access between them. In some
other cases, a gateway is not necessary for P-ITS-S in its applications.
7 Use case overview and principles
7.1 Basic principles for use case definitions
Basic principles have been established as guidelines to define the use cases.
The use case clusters shall describe the interaction between the P-ITS-S, V-ITS-S, C-ITS-S and R-ITS-S.
The users of the P-ITS-S include vehicle owners, vehicle drivers, vehicle and public transport passengers,
pedestrians and bicycle-travellers. In emergency service procedures, the victims and rescuer become
the user of the Personal Station. The information or message of the ITS application for a personal ITS
station may come from a Vehicle Station, a Central Station, a Roadside Station or even another personal
ITS station. The access to a Vehicle Station via a V-ITS-SG installed in a vehicle with connection to the
electronic systems has been described in ISO 13185.
The participants in the supply chain for the ITS service and applications concerned with the V-ITS-
SG such as the Vehicle Station product supplier, the V-ITS-SG product supplier, customer (e.g. vehicle
owner), vehicle manufacturer and diagnostic tool suppliers are also described in ISO 13185. The other
participants in the supply train of the ITS service and applications include telematics service provider,
traffic information service provider, broadcast and communication service provider, road owner, etc.
7.2 Use case clusters
This subclause provides an overview about the different use case categories. The use cases are grouped
into use case clusters.
