  2. Your Session Leaders HOST: Pamela Kordenbrock Architecture Implementation Program Manager Office of Transportation Management FHWA Office of Operations (Washington, DC) PRESENTER: Mac Lister ITS Specialist Operations Technical Service Team FHWA Resource Center (Olympia Fields, IL) National ITS Architecture and ITS Standards

  3. Learning Objectives You will be able to: • Describe in general terms the National ITS Architecture, the need for it, and associated benefits • Explain the connection between the National Architecture and ITS standards National ITS Architecture and ITS Standards

  4. System Architecture System architecture is a conceptual frameworkthat: • Supports system planning, definition, and integration • Describes how system components interact and work together to achieve the system goals • Describes the system operation, what each component does, and what information is exchanged among the components National ITS Architecture and ITS Standards

  5. What does an ITS Architecture do? • Provides a framework for an intelligent transportation system • Functionally defines • The pieces of the system • The information that is exchanged between them National ITS Architecture and ITS Standards

  6. Traffic Traveler Info No Delays Thru Exit 56 road network conditions request for road network information Transit Emergency Services ITS Architecture Involves Agencies, Systems, Communications, and Information Exchange National ITS Architecture and ITS Standards

  7. The National ITS Architecture: FRAMEWORK and TEMPLATE for use in the development of ITS ARCHITECTURES National ITS Architecture and ITS Standards

  8. National ITS Architecture Components Requirements The National ITS Architecture National ITS Architecture and ITS Standards

  9. User Services National ITS Architecture and ITS Standards

  10. User Services • 33 transportation services describing what, from the user’s perspective, the system should do • NOTE: A selected subset of all possible transportation services • Each User Service has associated User Service Requirements National ITS Architecture and ITS Standards

  11. Focuses and Relationships National ITS Architecture User Services Logical Arch Physical Arch Focus onNeeds Focus onProcesses Focus on Systems The “How” The “What” The “Where” National ITS Architecture and ITS Standards

  12. PHYSICAL ARCHITECTURE LOGICAL ARCHITECTURE National ITS Architecture and ITS Standards

  13. Logical Architecture Processes Data Flows National ITS Architecture and ITS Standards

  14. current position map data destination selected route Select Route Direct Driver directions traffic conditions current position The Logical Architecture Defines: • Functions to be performed • Data that flow between functions USER SERVICE: Route Guidance PROCESSES National ITS Architecture and ITS Standards

  18. Subsystems are Composed of EQUIPMENT PACKAGES A subsystem can be subdivided into implementable pieces called equipment packages. Transit Vehicle Subsystem On-board Transit Security On-board Transit Security On-board Transit Fare and Load Management National ITS Architecture and ITS Standards

  19. Info. Svc. Provider: Traffic Mgmt. Subsystems Can Be Aggregated and Replicated Big City TMC Info. Service Provider: Traffic Mgmt. Regional TMC Info. Service Providers: Traffic Mgmt. Emergency Mgmt. Small City TMC TMC = Traffic Management Center EMC = Emergency Management Center National ITS Architecture and ITS Standards

  20. ITS Subsystems Terminators Physical EntitiesTerminators Terminators Define the Architecture Boundary Four Types of Terminators: • Human • System • Environment • “Other System” National ITS Architecture and ITS Standards

  21. Other TMC Physical EntitiesTerminators National ITS Architecture and ITS Standards

  22. Physical ArchitectureArchitecture Flows Architecture Flows: Exchanges of information between subsystems and between subsystems and terminators in the Physical Architecture that collectively result in an integrated system National ITS Architecture and ITS Standards

  23. Physical ArchitectureConnecting Physical Entities: Architecture Interconnects National ITS Architecture and ITS Standards

  24. Architecture Interconnects:The Telecommunications Backbone • Fixed-point to Fixed-point • Wide-Area Wireless (Mobile) • Dedicated Short-Range Communications (DSRC) • Vehicle-to-Vehicle National ITS Architecture and ITS Standards

  25. Implementation Strategy Market Packages National ITS Architecture and ITS Standards

  26. Physical ArchitectureMarket Packages • Identify the pieces of the Physical Architecture that are required to implement a particular transportation service • Are tailored to fit real-world transportation problems and needs • Collect together several different: • Equipment packages • Architecture Flows National ITS Architecture and ITS Standards

  27. Example-Market PackageTraffic Management Service Area This is a subsystem This is an equipment package This is a terminator National ITS Architecture and ITS Standards

  28. Standards Standards National ITS Architecture and ITS Standards

  29. RELATION BETWEEN THENATIONAL ITS ARCHITECTURE AND ITS STANDARDS • The National ITS Architecture defines a common framework for ITS integration • The ITS standards define how the system components operate within the framework • Use of non-proprietary ITS standards facilitates interoperability within a system and between systems • ITS devices within an agency • ITS devices between regional agencies National ITS Architecture and ITS Standards

  30. What is a “Standard”? standard, n. “something established by authority, custom, or general consent as a model” Why are standards needed? X National ITS Architecture and ITS Standards

  31. Transportation Standards: Examples Transportation systems already use standards in traditional settings in order for the industry to operate safely and efficiently: • Manual on Uniform Traffic Control Devices (MUTCD) • Highway Capacity Manual 2000 • Rail gauges • Pavement marking standards National ITS Architecture and ITS Standards

  32. ITS Standards & the National ITS Architecture • ITS standards define Interfaces between Physical Architecture Entities • Subsystem to Subsystem • Subsystem to Terminator Traffic Management Subsystem incident information Emergency Management Subsystem ITS Standards are mapped to Architecture Flows National ITS Architecture and ITS Standards

  33. ITS StandardsInterface Implementation Options • Closed • Not available for after-market enhancements • Controlled by a single vendor for profit • Proprietary • License fee often required for use • Controlled by a single vendor for profit • Open • Consensus-based process • Controlled by a standards development organization • Open technology available to any vendor National ITS Architecture and ITS Standards

  34. ITS StandardsOpen Standards Lead to... • Interoperability - different types of devices on the same communications channel • Interchangeability - multiple brands of a device on the same communications channel • Expandability- add future devices or upgrade current standard CD Player Receiver Future Device Audio Standards CD Player Cassette Player Future Device National ITS Architecture and ITS Standards

  35. US DOT ITS STANDARDS PROGRAM • Working toward widespread use of ITS standards to encourage interoperability within and between transportation modes • Cooperative agreements with seven standards development organizations (SDOs) • Accelerated development of ITS standards that are: • Non-proprietary, consensus-based • Developed with input from public sector transportation professionals National ITS Architecture and ITS Standards

  36. ITS StandardsDevelopment Status National ITS Architecture and ITS Standards

  37. ITS StandardsAre Standards Required? • NO. A standard is not required unless it is adopted through US DOT rulemaking • Rulemaking is an option but not the US DOT’s preferred way of getting standards into ITS deployments --rather, quality standards combined with technical assistance • If rulemaking takes place, likely the standard would have already been considered the de facto standard National ITS Architecture and ITS Standards

  38. GUIDANCE for STAKEHOLDERS On the Use of ITS Standards • US DOT strongly urges agencies to use ITS standards • The Standards Program offers many resources to agencies • Technical Assistance through ITS Specialists • Peer-to-Peer Assistance • Individual, intensive support through Standards Field Support Team (SFST) • Visitwww.standards.its.dot.gov National ITS Architecture and ITS Standards
