Slide 3: National ITS Architecture Overview

Slide 4: What is ITS?

  • Intelligent Transportation Systems (ITS) include the electronics, communications or information processing used singly or integrated to improve the efficiency or safety of surface transportation
  • Examples:
    • Traffic signal controllers
    • Traffic Management Centers
    • "511" (traveler information)
    • Electronic toll-tagging

Slide 5: What is an ITS Architecture?

  • Framework for Developing Integrated Transportation Systems
  • Identifies:
    • Organizations
    • Systems operated
    • Functions performed
    • Communications
    • Information exchanged

Slide 6: ITS Architectures Provide a Framework for Integration

[This slide is titled "ITS Architectures Provide Framework for Integration." It shows data flows between Traffic, Travelers, Transit, and Emergency Service Providers.]

Slide 7: What is the National ITS Architecture?

  • HIGH-LEVEL national framework, "blueprint", used to help guide ITS deployment and transportation planning
  • Based on 33 transportation related ITS User Services:
    • Physical Entities – Subsystems/Terminators
    • Logical Architecture – Processes, Data Flow
    • Interfaces – Information Flows
    • Deployment oriented Market Packages

Slide 8: Architecture Products

Available on

  • CD-ROM
  • Website

Contains

  • Hypertext
  • PDF docs
  • Databases

Slide 9: Subsystems

  • Part of the overall Intelligent Transportation System
  • Identify major systems, functionality
  • Identify major interfaces
  • Define key standardization points
  • 4 Categories
    • Centers
    • Field
    • Vehicles
    • Travelers

Slide 10: Subsystem Diagram

[This slide is titled "Subsystem Diagram." This slide displays a top-level Architecture Interconnect diagram. The diagram is sometimes called the "sausage" diagram and shows subsystems in the National ITS Architecture. The subsystems are: travelers; Centers; Vehicles, and; Field.]

Slide 11: Terminators Define the ITS Boundary

  • Entities outside of ITS
  • Define interfaces but not functionality
  • Four types of Terminators
    • Environment
    • Human
    • System
    • Other System

Slide 12: Market Packages

Architecture
Framework spanning all of ITS

Market Packages
Contain pieces of the architecture that provide a particular transportation service

Slide 13: "Architecture Flows" Define Information Exchanged

[This slide it titled "Architecture Flows Define Information Exchanged." This slide displays an example of an Architecture Flow where information is exchanged. In this example, an Event Promoter sends event plans information to a traffic management center, which in turn sends information to an emergency management center.]

Slide 27: Turbo Architecture Version 4.0 Update

Slide 28: What Turbo Does

[This slide is titled "What Turbo Does," referring to Turbo Architecture software program. The slide shows an example of how the software approaches creating a regional architecture by personalizes it and customizes it for a specific region or project. In this example, the slide shows an image of a general interface between a traffic management subsystem and a transit management subsystem and use that as a template to define the interface between a city PWD and city Transit. ]
