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
