Southeast Michigan 2014 Test Bed project architecture: Implementing the USDOT´s Connected Vehicle Reference Implementation Architecture

The US Department of Transportation´s (USDOT) Southeast Michigan Connected Vehicle Test Bed originally hosted the USDOT Proof of Concept Testing (POC), starting in 2007. At that time, the architecture was designed around what was referred to as the Service Delivery Node (SDN). The SDN was a relatively closed system that handled data “collection”, processing (applications) and data dissemination back to the vehicle. While effective for these early tests and development efforts, this closed architecture was not conducive to growth and expansion. The USDOT, following the success of the POC, initiated the development of a Connected Vehicle Reference Implementation Architecture (CVRIA), and in 2013 began the final design of trial implementation of the CVRIA at the USDOT´s Southeast Michigan Connected Vehicle Test Bed. All users of this facility will be encouraged to develop and deploy solutions (hardware and software) using a common graphical language that is based on the updated ITS National Architecture. The authors will present the Southeast Michigan 2014 Test Bed architecture as it is being designed and deployed in this trial, describing the different architectural views and how they will lead to final design documentation. The Test Bed must be built to accommodate a wide range of user agreements, to be secure as well as accessible to a wide range of users, the traveler - often multi-modal, commercial and transportation providers and authorities. In this paper we present the proposed system architecture and our process for evaluation through industry collaboration.
