ARC-IT T 3 § Describe the integration of the National ITS Architecture, version 7. 1 with the Connected Vehicle Reference Implementation Architecture (CVRIA) § Illustrate how ARC-IT relates to the National ITS Architecture v 7. 1 and CVRIA § Tour the Website § Describe the tools—what they are, what they are used for, and who should use them in planning for deployment § Discus how ARC-IT fits into the deployment process and where to find out more § Presenters: □ Steve Sill, US DOT ITS Joint Program Office □ David Binkley, Iteris □ Kingsley Azubike, FHWA Office of Operations U. S. Department of Transportation ITS Joint Program Office 2

ARCHITECTURE EVOLUTION

National ITS Architecture is a “Living Document” §Continuing evolution of the architecture over 20+ years §Version 6. 1 continues support for User Architecture ITS technical evolution and Services Published HRI Version 2. 0 1993 deployment 1996 1997 ADUS V 3. 0 1998 1999 Transportation MCO Security Version Ver. 4. 0 2002 Ver. 5. 0 2003 6. 0 2007 Version 6. 1 7. 0 2009 2012 CVRIA V 7. 1 2015 ARC-IT 8. 0 2017 U. S. Department of Transportation ITS Joint Program Office 4

History Has Led Us Here § Both the National ITS Architecture and CVRIA support needed activities in ITS § Version 8 merges both architectures to support all of the stakeholders’ needs National ITS Architecture U. S. Department of Transportation ITS Joint Program Office 5

ARC-IT Scope ARC-IT National ITS CVRIA Architecture § ARC-IT combines services of National ITS Arch with connected vehicle content of CVRIA U. S. Department of Transportation ITS Joint Program Office 6

Combined/Merged Architecture § Continue to support regional planning and project implementation Monitoring & Evaluation Operations & Maintenance Transportation Planning Funded Projects Project Development Implemented Projects U. S. Department of Transportation ITS Joint Program Office 7

Merging Architectures § Layers Views U. S. Department of Transportation ITS Joint Program Office 8

ARC-IT Structure and Organization § Defined around 4 views: □ Enterprises to carry out services □ Functions to implement services □ Physical objects to implement that functionality □ Communications protocols required for implementation § Organized by Service Packages U. S. Department of Transportation ITS Joint Program Office 9

ARC-IT Service Packages § Service Packages grouped by Area Traffic Management Public Safety Data Management Public Transportation Parking Management Support Maintenance and Construction Commercial Vehicle Operations Vehicle Safety Traveler Information Sustainable Travel Weather U. S. Department of Transportation ITS Joint Program Office 10

ARC-IT Physical View § Depicts: □ Physical objects that interact to deliver services □ Interfaces and flows of information between those physical objects § Identifies options for… □ Interfaces to support ITS services □ Allocation of functionality □ Security safeguards U. S. Department of Transportation ITS Joint Program Office 11

Physical View- Physical Objects § Organized into 5 Classes U. S. Department of Transportation ITS Joint Program Office 12

Physical View- Interconnect Diagram U. S. Department of Transportation ITS Joint Program Office 13

Service Package Example – Transit Signal Priority U. S. Department of Transportation ITS Joint Program Office 14

ARC-IT Communications View § Depicts: □ Layered communications protocols that support communications between physical objects § Identifies options for each interface □ Appropriateness of protocols at all layers □ How these protocols ensure or support: ▪ Security ▪ Privacy □ Status of protocols as standards and the implications of their use U. S. Department of Transportation ITS Joint Program Office 15

ARC-IT Communications View Example U. S. Department of Transportation ITS Joint Program Office 16

Using ARC-IT: Framework for ITS Standards § Interfaces defined in ARC-IT identify what to standardize □ Many ITS standards documents contain a section mapping their outputs to the interfaces of ARC-IT § Use of Architecture as a framework for standardization continued with CVRIA and connected vehicle standards § ARC-IT pulls all of these standardization efforts into one common framework § ARC-IT is compatible with current international standards harmonization efforts U. S. Department of Transportation ITS Joint Program Office 17

ARCHITECTURE TOOL SET

ARC-IT Tool Suite § Two free downloadable software tools available to apply ARC-IT to regions and projects □Regional Architecture Development for Intelligent Transportation (RAD-IT) □Systems Engineering Tool for Intelligent Transportation (SET-IT) U. S. Department of Transportation ITS Joint Program Office 22

What is RAD-IT? § Formerly known as Turbo Architecture § Supports ARC-IT § To create and maintain ITS architectures § Includes conversion utilities for current regional architectures § Free tool available at www. arc-it. net (select Resources / Tools) § Training available under Resources / Training U. S. Department of Transportation ITS Joint Program Office 23

RAD-IT – new Look & Feel, familiar steps U. S. Department of Transportation ITS Joint Program Office 24

RAD-IT includes all of ARC-IT U. S. Department of Transportation ITS Joint Program Office 25

What is SET-IT? § Systems Engineering Tool for Intelligent Transportation (SET-IT) § Originally to support tailored CV project architecture development (using CVRIA) § Expanded to include all ITS § Creation of diagram based project architectures covering the Physical, Enterprise and Communications Viewpoints § SET-IT Training at www. arc-it. net (select Resources / Training). U. S. Department of Transportation ITS Joint Program Office 26

Purpose of SET-IT § Support project’s systems engineering analysis § Develop project architectures for ITS deployments, pilots, and test beds U. S. Department of Transportation ITS Joint Program Office 27

SET-IT – visually customize a project’s architecture U. S. Department of Transportation ITS Joint Program Office 28

Scope of Tools § RAD-IT focuses on regional planning and the development of Operations Concepts, □ Stakeholders, Physical Objects, Service Packages, Interfaces for the region § SET-IT is project-focused □ scope specified in the regional architecture □ graphical tool, ▪ providing visual feedback and tools to manipulate service package diagrams ▪ develop communications stack templates, specify standards at all protocol layers, □ Outputs – documents, diagrams, tables U. S. Department of Transportation ITS Joint Program Office 29
