Introduction

The standard deliverables “Mixed Vendor Environment Guide” CEN/TR 17401, “Mixed vendor

environments methodologies & translators” CEN/TS 17400, and this document provide a suite of

standards designed to achieve successful implementation of “Urban-Intelligent Transport Systems” (U-

ITS) in a mixed vendor environment.

This suite of standards supports the family of existent standards, referencing both common

communications protocols and data definitions, that, in combinations, enable Urban-ITS (and ITS in

general) to function and be managed, and will reference application standards, and their

interdependencies and relationships.

Urban authorities use an increasing array of ITS implementations to deliver their services. Historically,

urban ITS implementations have tended to be single solutions provided to a clear requirements

specification by a single supplier. Increasingly, as ITS opportunities become more complex and varied,

they involve the integration of multiple products from different vendors, procured at different times and

integrated by the urban authority.

The need for a mixture of systems provided by different manufacturers to so-called “Mixed Vendor

Environments” (MVEs) is a growing paradigm, which results primarily from the demand for the

introduction of competition in the context of public tenders, and the increasing networking of existing

stand-alone solutions to address complex traffic management systems.

The mix of systems of different manufacturers is also, in part, a result from technological changes.

Established companies are suddenly in competition with new companies that exploit technological

changes and offer exclusively, or at a reasonable price, new or improved functionality for sub-systems.

However, ITS design is often proprietary and, as a consequence, integration and interoperability can be

difficult, time-consuming, and expensive, limiting the ability of urban authorities to deploy innovative

solutions to transport problems. In some member states of the European Union, national/regional

solutions to this problem have been created, and there are also some solutions in specific domains, which

have been very beneficial. However, these are not uniform across the EU, compromising the efficiency of

the single market.

This document focuses specifically on the area of traffic management systems in an MVE, identifies

appropriate standards to use to enable an MVE, and addresses aspects associated with the

accommodation of regional traffic standards in such mixed vendor environments, with particular

emphasis on the centre/field systems context. This document also provides information regarding MVE

provisions in the public transport domain.

This document should be read together with CEN/TR 17401, which provides a ‘Guide’ giving a high level

introduction into the “Concept of Operations” (CONOPS) for MVEs; provides a high-level architectural

context explanation of an MVE and its operational requirements, and describes the problems and effects

that are associated with vendor lock-in. It also provides a systematic approach for many aspects of U-ITS

implementations, and indeed almost all ITS MVE implementations; and provides a methodical guideline

with a procedural model, in order to provide assistance to implementers and managers involved with the

structure of an MVE and/or with the removal of vendor lock-in.

This document should also be considered together with CEN/TS 17400, which provides the

methodologies and translators to avoid vendor lock-in, introducing suitable methodologies for system

architecture design, making appropriate use of standards, and specifications to be used when translator

systems are adopted.

Over many decades, regional traffic interface standards have evolved and been implemented around

Europe. Implemented, they cannot be replaced in the near term. This document is designed to show how

they can operate, co-exist and evolve in an MVE over time.

CEN/TS 17402:2020 (E)

This document also describes the major existing regional traffic standards established in Europe, such as

OCIT, UTMC, DVM/IVERA, and the data exchange provisions provided in the DATEX II series of standards,

and how these regional traffic standards and DATEX II are used in MVE or to avoid vendor lock-in. This

document recognizes that there are other implemented local traffic management standards and is

designed to enable them to also seek to achieve an MVE accommodation path.

The organization of the deliverable is based on functionality, and will provide framework overviews, and

minimum system requirements for ITS service provision in the context of regional traffic standards MVEs.
