Introduction
1 2 3
CEN/TR 17401 CEN/TS 17402 and CEN/TS 17400 are a suite of standards deliverables designed to
achieve successful implementation of urban-ITS systems in a mixed vendor environment. This document
should be considered as the introductory part.
This suite of standards deliverables supports the family of existent standards, and those under
development, 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 intelligent transport systems (ITS) to deliver their services.
Historically, urban ITS 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 change.
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, consequently, 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, 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 Europe, compromising the efficiency of the single market.
CEN/TR 17401, this document, is a ‘Guide’ providing a high-level introduction into the concept of
operations (CONOPS) for a mixed vendor environment (MVE); provides a high-level architectural context
explanation of an MVE and its operational requirements, and describes the problems and effects are
associated with vendor lock-in. It also provides a systematic approach for many aspects of Urban-ITS
implementation, and indeed almost all of ITS MVE implementations; and provides a methodical guideline
with a procedural model, in order to assist implementers and managers involved with the structure of an
MVE and/or with the removal of vendor lock-in.
CEN/TS 17402 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 (RTS) in such mixed vendor environments (RTS-MVE), with
emphasis on the centre/field systems context.
CEN/TS 17400 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.
Against this background, this document is designed to enable ITS architects to develop architectural
concepts for mixed-manufacturer systems in order to achieve the migration of existing monolithic single-

designed to actively support the implementation of distributed and open system structures for regionally
and nationally networked systems in the transport sector throughout the European Union.
