Southeast Michigan 2014 Test Bed project architecture update: Developing, refining and implementing the USDOT's Connected Vehicle Reference Implementation Architecture

Abstract

The US Department of Transportation's (USDOT) Southeast Michigan Connected Vehicle Test Bed originally hosted USDOT Proof of Concept Testing (POC), starting in 2007. Following the success of the POC, the USDOT initiated the development of a Connected Vehicle Reference Implementation Architecture (CVRIA), and in 2013 began the final design and trial implementation of the CVRIA at the USDOT's Southeast Michigan Connected Vehicle Test Bed. All users of this facility are encouraged to develop and deploy solutions (hardware and software) using a common graphical language that is based on the updated Intelligent Transportation Systems (ITS) National Architecture. The development of the project architecture for the Southeast Michigan 2014 Test Bed project has been an iterative process as it is the first real-world implementation of the CVRIA. As a result, the initial architecture design shown in December 2013 has evolved significantly based both on lessons learned from the development and showcasing of the architecture and from the implementation of various components to facilitate implementation and long-term growth and use of the system. The Southeast Michigan Test Bed has been built to accommodate a wide range of user agreements. It is secure and accessible to a wide range of users, including the traveler — often multi-modal — and commercial and transportation providers and authorities. In addition, it is flexible enough to support additional test beds throughout the country by providing a common platform that permits those facilities to focus their resources on testing and developing applications and systems that are relevant to those test beds. In this paper, we present the updated system architecture and our process for evaluation through industry collaboration.
