Intelligent Transportation Systems
What is a Concept of Operations?
A Concept of Operations is a high-level description of what the major system capabilities will be – it attempts to answer the Who, What, When, Where, Why, and How for the system in general terms for all participants

Intelligent Transportation Systems
Concept ofOperations
How: WhatResources do we
need to design andbuild the system?
Who: Who arethe Stakeholdersinvolved with the
system?
Where: What arethe geographical andphysical locations of
the system?
Why: What doesyour organization
lack that thesystem willprovide?
When: What isthe time-
sequence ofactivities that willbe performed?
What: What are theknown elements and
the high-levelcapabilities of the
system?
Components of the Concept
Intelligent Transportation Systems
Why Now?
Hasn’t the NaviGAtor system been in place for over 10 years?
Yes, but:– No formal Concept of Operations– Changes in the ITS landscape– New services offered– Many unanswered questions
Intelligent Transportation Systems
Questions
How will the system be expanded?
What is the role of GDOT and
local agencies?
What future services will
NaviGAtor support?
Will signals be integrated into NaviGAtor??

Results of Stakeholder Interviews
• Local governments are in the business of operating signals
• ITS can enhance their ability to operate signals (move traffic on the arterials)
• Almost all local agencies are pleased with the level of support they get from GDOT in signal operations and maintenance
Intelligent Transportation Systems
Results of Stakeholder Interviews
• Most all local agencies plan to have a traffic control center
• Most local agencies see a need to staff their TCC, but do not have the resources
Intelligent Transportation Systems
Stakeholder Interviews
• GDOT should set the vision and communicate it to the local agencies
• GDOT should develop flexible specifications
• Coordination with the Construction and Bridge Departments is a challenge
• ITS maintenance is a challenge – would like GDOT’s support
Intelligent Transportation Systems
Stakeholder Interviews
• Most all agencies see the value in a centralized transportation management system which lets GDOT and agencies share data
• Almost all agencies support the idea of GDOT providing both signal and TCC software
• NaviGAtor software adds little value to local agencies when compared to the cost and effort to maintain
• Most all agencies see a need to integrate status and some control aspects of ACTRA into NaviGAtor
