## National ITS Architecture Overview

## 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

## What is an ITS Architecture?

**What is an ITS Architecture?**

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

## ITS Architectures Provide a Framework for Integration

**Travelers**

**Emergency**
**Service Providers**

**Transit**

**Traffic**

## 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

**National ITS Architecture**

**Architecture Products**

- Available on
- CD-ROM
- Website
- Contains
- Hypertext
- PDF docs
- Databases

## 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

## Subsystem Diagram

## Terminators Define the ITS Boundary

**ITS**
**Subsystems**

**Terminators Define the ITS Boundary**

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

## Market Packages

**Market Packages**

**Transit**
**Vehicle**** **

**Transit**
** ****Management**** **

_**Market Packages**_

- Contain pieces of the architecture
- that provide a particular
- transportation service

_**Architecture**_

- Framework spanning all of ITS

## “Architecture Flows” Define Information Exchanged

## National ITS Architecture Version 6.0 Update

## Turbo Architecture Version 4.0 Update

## What Turbo Does

***Turbo***** is a software tool that automates**
**use of the National ITS Architecture.**

**Notes:**
Takes this national framework that described above and personalizes it and customizes it for a specific region or project.  In this example, we take 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. 

## Turbo Version 4.0

**Turbo Version 4.0**

- Comprehensive Upgrade will include
- Support for Version 6.0 of the National ITS Architecture
- Enhancements that focus on improving project definition based on a regional ITS architecture
- Bug fixes to ensure trouble-free operation

## Version 4.0 Project Enhancements

- Version 4.0 is the first Turbo upgrade to focus on project definition capabilities
- Focus on Regional ITS Architectures until now
- Project definition interface will be revamped to make it more intuitive
- New features will be added to make project definition more useful and powerful

## Improved Project Interface

**Improved Project Interface**

- Modify Turbo interface to make project definition more intuitive

## Improved Project Interface

**Improved Project Interface**
