• Fast evolution towards a smart vehicle
• Initial communication standards where wiredsolutions: CAN (Controller Area Network) – ISO 11898, LIN (Local
Interconnect Network), MOST (Media Oriented Systems Transport) and
K-LINE ABS, EBS, TCS, EPS
• REVOLUTION: wireless and mobile technologies
GPS Navigation, Bluetooth, etc.

How to achieve ITS challenges?
R&D Projects
Consortiums and Organisms
Cooperation and liaison
Standardization and interoperability
Car Manufactures
Services & Infrastructure
Applications
Security
Architectures
Benefits for users
(safety, mobility,
entertainment, etc.)

How can we assure these benefits?
• Standardization (Several activities): IEEE
802.11p, DSRC, CALM, Traffic and Travel Information, etc.
• Interoperability: Standardization and …
Certification and Testing

Why a Certification Programme?
• Even when products are based on standards, there is a
long way from standards to interoperable implementations
in the market. Different implementations of the same
standard may not be interoperable.
• Consortiums and organizations promoting either a
technology or the associated services, define compliance
requirements to foster product interoperability.
• The process a product shall follow to achieve a
Compliance Logo is defined in a Certification Programme.
• Some Certification Programmes

Why a Certification Programme?
Our vision for ITS Certification: A reliable and
trusted Certification Programme for ITS
products, based on third party testing and
supported by a well recognized logo
• A certification program should
– … be tailored taking into account the specific
needs for each consortium, technology or
service.
– … guarantee interoperability.
– … not compromise the technology or service
success in the market
No ITS Certification Programme

ITS Certification Framework: SAFESPOT
• Its purpose is to guarantee compliance to
SAFESPOT Specifications and that SAFESPOT
devices will be interoperable with other vendor
equipments
• It is independent of the products to be certified
• It is based on GST-CERTECS work

Build the Certification Framework
Establish the SAFESPOT Forum
Develop a web site for repository of
documents and certificates
Develop certification Policy
documents
Develop Test Specifications
Select a SAFESPOT Certification
Administrator
Select SAFESPOT Test Laboratories
and SAFESPOT Certification Bodies
Validate SAFESPOT Test Tools
Run the certificate scheme.

Phase 1: What do we need to certify in ITS?
• Heterogeneous and distributed environment
• Diversity applications and situations
What are the proper functionalities to be certified?
• It is depends on the ITS system; e.g. eCall is also
working in defining its own certification
• SAFESPOT decided to certify V2V&V2I interface
and beaconing functionality

Phase 2: Type of testing for ITS
What type of testing is needed for assuring safety?
What type of testing is needed for getting trust in ITS?
• It is depends on what type of functionality or
product will be tested: protocol, electronic devices,
GUI interface, application, user experiences, etc.
• Interoperability must be always performed
ETSI is currently defining a STF for standardizing a new methodology
and framework for interoperability testing of Distributed System

• Standardized testing
language and test system
architecture (ES 201 873-X)
• It has been used and
widely accepted.
• Single language for many
testing activities
• Reduces testing cost
• Areas of application:
protocolos, API, services,
etc

Conclusions
• A wide set of initiatives both Europe, USA and Japan
• Cooperation between R&D projects and Consortiums
• Convergence goes through standardisation and
certification for interoperability
• In the future, certification should share and use
elements from both the Institutionals (public sector)
and Forums (private sector)
• New testing challenges are coming up (e.g. Field
Operational Testing and Distributed Interoperability
testing), and must certification consider these new
challenges?
Infrastructure, user terminal, on board unit and
services will benefit from standardization, certification
and testing
