  1. Connected Vehicle Reference Implementation Architecture (CVRIA) David Binkley, Iteris

  2. Topics • recent activities regarding the development and uses of the Connected Vehicle Reference Implementation Architecture (CVRIA) • user tools based on CVRIA that are being developed to support Connected Vehicle project planning and development

  3. CVRIA Overview Program Background Project Goals and Approach Recent Activities

  4. CVRIA Landscape Applications • Looking ahead • 10-20 years from now when 80% of vehicles are equipped in some way – maintaining a robust CV environment • Shorter term – supporting the researchers and early deployers • Collecting and aggregating connected vehicle needs • Developing a multi-faceted architecture • Identifying and prioritizing candidate interfaces for standardization • Supporting policy analysis

  5. Architecture & Standardization Plan The CVRIA provides a reference for applications and systems as well as identifying candidate interfaces within the architecture. But… how do we implement those interfaces? Standardization is a critical component of implementation. The standardization plan will provide a strategy for ensuring that there are sufficient standards to support implementation and ensure interoperability. Candidate Interfaces Create Adopt Adapt or

  6. CVRIA Viewpoints • CVRIA uses multiple viewpoints to capture stakeholders’ concerns • Enterprises to carry out applications • Functions to satisfy requirements • Physical objects to implement that functionality • Communications protocols necessary • ~100 connected vehicle applications included

  8. CVRIA Website – Reduced Speed Zone Warning (RSZW)

  9. CVRIA Status • CVRIA v1 complete in January 2013: http://www.iteris.com/cvria/index.htm • Public Workshops • San Jose, CA – April 30 2013 • Focused on draft architecture views • San Francisco – February 2014 • Focused on inputs to standardization plan • Webinar Series – fall 2013 • T3 Archive: http://www.pcb.its.dot.gov/t3_archives.aspx • 7 webinars, each provided general overview and then drilled into specifics of 2 or 3 CV applications • Contact Us page or “Comment on Page” links to ask questions or provide comments to the team

  10. What’s Next • CVRIA is providing the input into the standardization process • Architecture definitions, applications helping stakeholders verify that framework adequately captures the connected vehicle activities • Beyond that, it is becoming a resource in the near-term for project implementers – research, test bed projects • “Mini-Tool” developed to help define project architecture • Using CVRIA applications drawings as a starting point • Application of CVRIA to guide project development and application implementation

  11. Tools for Applying CVRIA • System Architectures are meant to be used • To understand new concepts, scope/define projects, present alternatives, capture interfaces and functions • Aka – supporting a systems engineering approach • New software tool available June 2014 • Systems Engineering Tool for Intelligent Transportation (SET-IT) • Takes all the content in CVRIA and makes it available for projects to start with a common base and customize/build upon it • June release includes basic physical view capabilities • Includes ability to select CVRIA applications and customize them for a local project • Supports systems engineering process activities with direct process outputs • Based on Visio and Access

  12. SET-IT

  13. SET-IT • Using CVRIA drawing stencil – allowing for easy comparisons, reuse across projects • Support customization for local variations

  14. SET-IT • Based on Visio drawing tools • Quickly import CVRIA drawings • CVRIA physical view includes more detail than current ITS drawings (security and other flow characteristics) • Add local customizations • Connections to database definitions Notional

  15. Software Toolset will be evolving • SET-IT initial release via CVRIA website June 2014 • Subsequent releases will build upon the physical drawings; look for: • Formal physical diagram hierarchy • Stakeholder tracking and Basic Enterprise drawings • Communications dialogs • CVRIA Enterprise imports • Communications State transitions • Message definitions • Enterprise correspondence rules – relationships between views • Web page generation • Formal document template outputs (ConOps, ICDs) • SET-IT – not an architecture tool but a tool for connected vehicle systems engineering

  16. Where is CVRIA Going • Long-term: CVRIA and National ITS Architecture will be integrated in approximately 2 years • Will include updated tools that will include support for regional ITS architecture • Look to websites to download tools and provide feedback: www.standards.its.dot.gov/cvria.asp www.iteris.com/cvria
