Why Build Intelligent Transit Agencies?
To operate more efficiently, effectively and safely for customers and management.
How To Build Intelligence
• Collect real time data from:– Voice annunciators– Fare collection systems– Passenger counting systems– Vehicle location systems
• Use the data to improve operations:– “Next Arrival” information for customers– Vehicle and driver assignments– Bus Stop Location planning
• Repeat process, above.
Intelligence Tools
• Technology applications have been available for transit:– ITS Devices– Data Management Software– Geographic Information Systems– Wireless communications– Internet
The Technical Challenge
• However, integration of applications has been elusive, often resulting in “stovepipe” deployments requiring expensive, customized databases and equipment and data interfaces
The Institutional Challenge
• Transit often operates across jurisdictional lines– Each jurisdiction exercises discretion
in selecting applications, each with its own proprietary data and hardware interfaces
– Yet, many applications depend on data from other jurisdictions
Today’s Opportunity
With the recent establishment of a National ITS Architecture, supporting standards and protocols and institutional rules and policies, the goal of deploying interoperable automated systems, across jurisdictional boundaries, is now within reach.
Why Is Integration Important?

Critical Elements to Success
• Architectural Framework• Standards and Protocols• Institutional Processes
Architectural Framework
• The “architectural framework” helps define all the pieces and how they relate
Standards and Protocols
• The “standards and protocols” help ensure that all the pieces fit together
Institutional Processes
• Policies and regulations that help guide regions with multiple jurisdictions to integrate the deployment of technology in an “intelligent” way

Standards and Protocols
• IEEE 1488/1489 Data Dictionary and Message Set Template Standards
• IEEE ITS Data Registry
• SAE 1708/1587, CAN/J1939, Lonworks and other Bus VAN Standards and Protocols
• IEEE 802.11 Dedicated Short Range Communications Standard
Institutional Processes
• FTA Policy on the National ITS Architecture fosters integration of deployment of regional ITS systems by:– Requiring Regional ITS Architectures to
be adopted locally– Requiring federally funded ITS projects
to use USDOT adopted ITS standards

In Summary
• Use of integrated ITS data helps build “intelligent transit agencies”
• Major federal investments in Architecture, Standards/Protocols development and Institutional Policy and Rulemaking provide a strong foundation for ITS data integration
