2.11 Indiana Statewide ITS Architecture, Draft
Developed concurrently with the Indiana ITS Strategic Plan and this Indianapolis Regional ITS
Architecture, the Indiana Statewide ITS Architecture is a tool for planning, deploying, and
integrating transportation systems throughout the state. While the Indianapolis ITS Architecture
focuses on the Indianapolis Region, the Statewide Architecture has been developed to include all
modes of transportation and all roads throughout the state, focusing on statewide and interstate
systems like commercial vehicle operations and the Gateway Traveler Information System. A
goal of the Statewide Architecture is to provide “a vision of how each transportation agency’s
systems will work together in the future to share information and resources in an effort to provide
a safer, more efficient, and more effective transportation system for travelers in the state.”
It is important to note that the naming conventions and other related parameters of the
Indianapolis ITS Architecture have been closely coordinated with the Indiana Statewide ITS
Architecture to promote interoperability and consistency between the two.
3.0 Previous ITS Architecture Efforts
Building upon the Indianapolis Area ITS Early Deployment Plan, a pair of ITS workshops were
held in 2000 and 2001 to bring together stakeholders from key transportation agencies in the
region. These “Tier I” and “Tier II” workshops provided the stakeholders with an introduction to
ITS, and then encouraged their participation in the initial steps of architecture development.
Findings from the Tier II workshop were collected and recorded using Turbo Architecture, a
software tool sponsored by the FHWA for ITS architecture development.
Results from the Tier I and Tier II workshops provide a bridge between the Indianapolis ITS
Early Deployment Plan and the Indianapolis ITS Architecture. The stakeholders, systems,
services, interconnections, and standards identified during all previous ITS architecture efforts
provide a starting point for current inventory tasks. Below is a listing of the stakeholders
identified during the Tier I and Tier II efforts.
