The US Department of Transportation has high hopes of standardizing the way autos talk to each other and with other intelligent roadway systems of the future.
The department recently issued a call for public and private researchers and experts to help it build what the DOT called "a hypothetical four layer approach to connected vehicle devices and applications certification."
The idea is to develop certification ensures that different components of intelligent travel systems that are manufactured according to connected vehicle technology requirements will be trusted by the system and by users, the DOT stated. With national interoperability comes the opportunity to establish national standards and criteria for certification of individual products that will have access to the system, system processes, and operational procedures.
Certification research will be primarily focused on understanding the needs for device compliance, system security, and privacy requirements. Application certification is separated into two parts; one part for communications interface certification, and another for overall functional certification of the application. This separation is necessary as interface semantics or message payload certification is applicable to one or more application.

The four layers of certification are: Environmental abilities, communication protocol abilities, Interface abilities (both the syntax and contents of the message payload transmitted over the communications medium), and overall application abilities, the DOT stated.
Certification research will be primarily focused on understanding the needs for device compliance, system security, and privacy requirements.
The DOT said its Intelligent Transportation Systems program will conduct research activities in support of certification in the following areas:
The DOT said milestones for certification activities must match related milestones in the other program roadmaps. For instance, a 2013 milestone for potential rulemaking on equipment requirements in vehicles must be matched by a similar milestone to have certification requirements and processes established in time for implementation of the rule. More specific milestones will be established in conjunction with the development of the individual program roadmaps.
