Incorporating a Regional Architecture in the Planning Process:
Central Ohio Example

Population: 1.24 Million 41 Member Agencies Major Interstate Routes:

University
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
Prepared by:
The Mid-Ohio Regional Planning Commission285 East Main Street
Columbus, OH 43215
Central Ohio Regional ITS Architecture“ITS components that operate together and as part of a system will enhance safety and mobility and reduce the possibility of
costly incompatible systems in the future.”

ODOT’s Columbus Freeway Management System
Freeway Incident Response Service Team (FIRST)
AVL and APC systems for COTA
Columbus Signal System Upgrades
ITS in the Planning Process
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
Transportation Improvement Program
MORPC staff selected ITS projects from the draft TIP list and verified conformance of each project to the Regional Architecture
11 projects in the 06-09 ITS Project Listing, including:– Central Ohio Transit Authority (COTA) ITS– Columbus Signal System upgrades– Franklin County signal timing studies– Paving the Way (Traveler Information)
Columbus Signal System Example
MORPC has $14.9 M programmed for improvements to the system over the next 6 years
System currently does not conform to the Regional Architecture
Consultant hired to perform a technical and operational assessment of the system and develop a strategic plan that will bring the system into conformance with the architecture
Columbus Signal System Cont’d
Final report will include a section on architecture conformity, which will be used in final design of the new system
Functional Flow Diagrams outline how the signal system should integrate with other agencies in the region
“Because upgrades to the CTSS are fully funded through MORPC, the new system design must conform to the Regional ITS Architecture.”

Regional project that stemmed from the architecture
Study will target cross-jurisdictional corridors $600,000 for 200 intersections Shows that agencies are starting to look at
the region as a whole
Learning As We Go
Better education/outreach to: – our member agencies– other agencies included in the architecture (e.g.
Police/Fire, Event Promoters, Media)
In the future, project owner will demonstrate compliance rather than MORPC staff
The architecture is a dynamic document, always changing
