Central Ohio Regional ITS Architecture History
1999 - MORPC created the “ITS Integration Strategy for Central Ohio” A good start, but lacking critical components
recognized by FHWA
2004 - MORPC adopted the “Central Ohio Regional ITS Architecture” TurboArchitecture 2.0 Incorporated FHWA recommendations from
Integration Strategy Updated triennially in conjunction with T-Plan

Step #1: Get StartedCentral Ohio Case Study
Original Need Increases in congested
travel & daily travel growth
Driven by numerous MPO funding requests
Declining member budgets
More reasons to update… Desire to incorporate
M&O activities in planning process (SAFETEA-LU)
Congested System (% of lane-miles)

Step #1: Get StartedCentral Ohio Case Study
Region & Timeframe MPO boundary/AQ conformity area 20 year horizon (T-Plan)
Identify (New) Stakeholders Build off established groups (housed
at MPO), then start adding… Active Outreach/Education with
stakeholders Identify Champion
MPO selected as champion Project champions

Columbus Traffic Signal System Assessment
City boundaries drive the need for close coordination with neighboring jurisdictions (15+) Poor cross-jurisdictional coordination Transit system desires traffic signal priority City and ODOT desire closer relationship between signal and
freeway management systems MORPC has $14.9 M programmed for improvements to
the system over the next 6 years Study will result in new design philosophy and will
conform to architecture standards
“Because upgrades to the Columbus System are fully funded through MORPC, the new system design must
conform to the Regional ITS Architecture.”

Step #2: Gather Data

11
Step #2: Gather DataCentral Ohio Case Study Inventory Systems/Plans
Existing / planned ITS systems ITS Studies
Determine Needs and Services ITS systems will provide Work with stakeholders to
determine Consensus building/visioning -
“What does the region need?” Work together to prioritize regional
projects
MPO’s can assist member govt’s get the information needed to make
informed planning decisions.
12
Step #2: Gather DataCentral Ohio Case Study
Develop Operational Concepts MPO to provide data on the possibilities ID roles and responsibilities of each stakeholder GET BUY IN!
Central Ohio Freeway Management System Example
Each update to the architecture offers a new regional visioning opportunity.

17
Step #4: ImplementationCentral Ohio Case Study
Define Project Sequencing Closely tied to the MPO Planning process Architecture process ensures that projects
are built in a logical sequence CM/AQ – Applications accepted on a 2 year
cycle TIP – 4 year schedule of transportation
improvements updated every 2 years T-Plan – 20 year horizon updated every 3
years
18
Step #4: ImplementationCentral Ohio Case Study
Develop list of Agency Agreements Existing and ID possible new
agreements Region okay with handshake
agreements - Only a few formal agreements in place: Joint ODOT & City operation of FMS 800 MHz radio system (33+ partners)
Projects have stalled or ended in the pursuit of developing MOUs

Why Develop (& Update) a Regional ITS Architecture?
Conclusions: Foundation for incorporating management and
operations into decision-making/planning (SAFETEA-LU emphasis area)
Continue to identify (and develop new) integration opportunities
Assist in identifying gaps in existing services (and finding solutions)
Efficient and effective project implementation structure
Tool to estimate funding needs (opportunity for new projects to get federal funding)
On-going educational opportunities
