This technical memo is part of a study sponsored by the US Department of Transportation (USDOT) and performed by the American Association of State Highway and Transportation Officials (AASHTO). The purpose of this project is to conduct analyses leading to a preliminary, general concept of a national connected vehicle field infrastructure footprint. Describing such a footprint satisfies many requirements in developing a policy foundation for the connected vehicle environment, including development of a set of desired outcomes which include:
A description, for State and local investment and decision makers, of the justification for and value of deployment of connected vehicle infrastructure.
A compilation of the data, communications, and infrastructure needs of the priority applications.
A set of generic, design concepts (at a high-level of engineering detail) that relate the infrastructure to the applications (or bundles of applications) and their needs under different operational conditions.
A set of State- and local-based scenarios identifying how and where agencies might implement secure, connected vehicle infrastructure and what funding strategies might use to support such deployment, and a synthesis of these scenarios into a preliminary national footprint of connected vehicle field infrastructure.
A phased deployment plan which identifies the actions and funding strategies needed over a period of time for coordinated implementation of a national connected vehicle field infrastructure.
Cost estimates for deployment, operations, and maintenance.
Estimates of workforce and training requirements; and identification of policy and guidance needs.
Identification of implementation challenges and institutional issues and identification of the timing by which those issues need to be resolved to achieve deployment.
This technical memo specifically relates to the identification and analysis of design gaps.
The purpose of this document is to identify, describe, and make recommendations to address apparent gaps between the National Connected Vehicle Field Infrastructure Footprint Analysis Design Concepts developed in Task 5 of the study and the ongoing technology development, design, implementation, policy development and governance of connected vehicle applications.
Following this introductory section, the document consists of a series of design gap discussions, structured loosely around topical areas of concern. The discussion of each gap consists of a one-sentence description or label, a summary of the key issues from which the gap arises, and recommendations for addressing the perceived gap.
