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

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

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
