Introduction and Executive Summary
This Intelligent Transportation Systems (ITS) Regional Architecture Plan was
developed in 2004 by the Metropolitan Planning Organization of Johnson County
(MPOJC), which provides transportation planning support for the Iowa City
Urbanized Area. The goal of developing a regional ITS architecture is to promote
consistency in information flows amongst the agencies operating our
transportation systems. The Iowa City Urbanized Area includes Iowa City,
Coralville, University Heights, Tiffin, North Liberty, and portions of Johnson
County within the growth area of these cities. The only “private” stakeholder is
the University of Iowa; although the University of Iowa is a public entity.
Since this plan was created in 2005, agencies and municipalities in the Iowa City
Urbanized Area have successfully organized a coordinated joint emergency
communications facility (JECC-EMA), which serves as an information and
communications clearing house for the region. Other agencies are planning for
technologies such as improved real-time passenger and professional information
systems, signal pre-emption for emergency vehicles, and integrated traffic
signals.
ITS Overview
Intelligent Transportation System Architecture is a framework for transportation-
related technologies and the sharing of technologies and information among
various transportation systems and authorities. ITS includes technologies such
as global positioning systems (GPS), interconnected signal systems, special
event traffic control strategies, along with many other computer-based
technologies. These technologies influence and improve the safe and efficient
flow of transportation within the community.
A regional architecture provides the framework and the basis for operational
agreements between agencies who share responsibility for the transportation
network. The two main components of an Intelligent Transportation System are
subsystem and information flows. Examples of a subsystem are technologies
such as Dynamic Message Signs and Automated Vehicle locator (AVL)
equipment. Information flows are data that is used to operate the subsystem and
to make informal decisions about transportation infrastructure. Examples of
information flows include real-time traffic flow information, crash data, event-
related traffic flows and bridge-ice data.
1. MPOJC Transportation Planning Boundary
The transportation planning boundary for the Iowa City MPO consists of the five
cities in the urbanized area plus each city‟s growth area. This includes Coralville,
Iowa City, North Liberty, Tiffin, and University Heights. The following map (Figure
Regional ITS Architecture for MPOJC Region

1) shows the transportation planning boundary. This planning area will be used
for ITS applications for MPOJC member governments.

A. Stakeholders
Stakeholders are those entities that are defined within the regional architecture
as public or private entities that have an interest in deployed ITS applications or
future ITS applications. These entities‟ interest may be the actual parties that use
or implement the ITS application or they may benefit by the ITS application. The
stakeholders identified for the MPOJC Urbanized Planning Area are:

B. How the Plan Was Created
MPOJC staff identified ITS stakeholders within the five area municipalities. Staff
held meetings with each city within the urbanized area, as well as the University
of Iowa and Johnson County in 2004 when the plan was originally developed. At
these meetings the existing ITS inventory, planned ITS projects, and future ITS
projects were identified for each entity within the urbanized area. Questions
asked of each entity can be found in the Appendix.
The first update to the Plan was conducted in late 2005. This document contains
the second plan update, which was completed in early 2014. During the summer
of 2014, feedback was sought from stakeholders to determine if any new ITS
technologies have been implemented, or are being considered, for each
respective organization. The findings and results of the update are incorporated
herein.
C. Urbanized Area Centers
The National ITS Architecture defined „Center‟ as the term used to identify an
area where ITS applications are managed or housed. Each City has its own
„Center‟ as identified below. The only current combined center is the Johnson
County Joint Emergency Communications Center.
The Metropolitan Planning Organization of Johnson County‟s urbanized area
centers are as follows:
Traffic Management Center- Iowa City Traffic Engineering, Coralville
Streets, North Liberty Streets
Emergency Management Center- Johnson County Joint Emergency
Communications Center, Iowa City Police & Fire, Coralville Police & Fire,
Johnson County Sheriff
Transit Center- Iowa City Transit, Coralville Transit, University of Iowa
Cambus, Johnson County SEATS
Fleet Vehicle Administration- Iowa City Streets Department, Coralville
Streets, University Heights, Tiffin, North Liberty Streets
Maintenance and Construction Management- Iowa City Public Works,
Coralville Public works, University Heights, Tiffin, North Liberty Streets

E. User Services/ Market Packages
User services define the role that ITS plays from the user‟s perspective. The
National ITS Architecture defines thirty-three (33) user services (See Table 1)
that are grouped into eight user service bundles. The US Department of
Transportation and ITS America jointly defined these user services and bundles,
using significant stakeholder input. The user service concept allows system or
project definition to begin by establishing the high level services that will be
needed to address stakeholders‟ problems and needs.

Market Packages represent slices of the architecture that address specific
services like surface street control. A market package collects together several
different subsystems, equipment packages, terminators, and architecture flows
that provide the desired services. For the MPOJC Regional ITS Architecture, the
following Market Packages were selected to provide the user services desired.
Travel and Traffic Management
Incident Management and Traffic Monitoring. Stakeholders have expressed
the need to identify and verify incidents along the major travel corridors using
video cameras. CCTV cameras were suggested as one alternative where
Regional ITS Architecture for MPOJC Region
13
incidents can be remotely viewed and managed from a traffic management
center. In addition, the sharing of the images from the cameras by other parties
involved with an incident can assure that a quicker response and proper
resources and actions are taken for incident management. Incident information
obtained via cameras and sensors can be distributed to motorists en-route via
permanent and portable message signs. Portable message signing was noted to
be useful to supplement permanent signing and to aid in diverting traffic around
incidents and providing guidance back to the original travel route.
Weather events can significantly affect travel in the Johnson County area.
Severe weather events (e.g. high winds, severe downpours, ice, snow, etc.) are
fairly common to the area. Stakeholders stated the specific need to merge
weather collection and reporting operations to gain a more comprehensive view
of real-time weather conditions. Much of this information is now available from
the Iowa „511‟ program.
Pre-Trip and En-Route Information. Stakeholders stated the need to increase
the distribution of pre-trip and en-route travel information. Pre-trip information can
be used to assist travelers in making mode choices, travel time estimates, and
route decisions prior to trip departure. This information includes (but is not limited
to) roadway environment (e.g. weather, visibility) and surface conditions (e.g. ice,
snow). En-route traveler information will be especially important to guide
travelers in, through, and around incidents along major travel corridors and other
impacted areas.
Much of this information is now available from the Iowa „511‟ program. Radio and
television traffic reports were also mentioned. Limited traffic reporting services
exist in the area today but may be expanded with the availability of information
on traffic conditions along major travel corridors.
Traffic Control and Highway-Rail Intersection. Stakeholders expressed
significant interest in enhancing signal coordination along and between major
travel corridors, including across the major jurisdictions in the Region. In addition,
providing signal pre-emption capabilities for emergency vehicles and key transit
vehicles was cited as a priority. Signal coordination and signal pre-emption
capabilities exist along some portions of the Region. However, cross-
jurisdictional issues are considerable and would need to be addressed.
Many highway- rail crossings near signalized intersections have railroad signal
pre-emption capabilities. At more remote locations, advanced warnings systems
are proposed to improve the safety of the crossings.
Public Transportation Operations
Public Transportation Management, En-Route Transit Information, Public
Travel Security. Transit stakeholders in the Region provide transit and traveler
Regional ITS Architecture for MPOJC Region
14
information to patrons in real-time conditions. These services may be provided
via kiosks or message boards at transit centers, via smartphone applications,
websites, as well as en-route (using annunciators and other tools).
To improve security of transit patrons (at transit centers, pickup/drop-off points,
and on-bus), the use of on-board security cameras is implemented.
Emergency Management
Emergency Notification and Personnel Security. The implementation of the
Joint Emergency Communications Center has streamlined emergency
management coordination efforts in the Region.
Emergency Vehicle Management. In responding to key or major incidents, the
monitoring of emergency vehicle availability and progress in reaching the incident
was cited as a major need for the Region in 2004. Since then, the use of AVL in
all levels of emergency vehicles has been progressing. Signal pre-emption for
emergency vehicles has also been implemented in some areas.
Information Management
Data Mart and Archived Data Function. Significant data and information are
needed to efficiently monitor and operate the Region‟s transportation system.
These data include: traffic volumes, vehicle classification data, vehicle speed
data, weather conditions, etc. They are used for planning purposes as well as for
daily operation of the facility. Several stakeholders collect this data for use in the
planning and development of future ITS technologies.
Maintenance and Construction/Work Zone Management
Maintenance and Construction/Work Zone Operations. Maintenance of the I-
80 and other major travel Corridors in an efficient manner, minimizing impacts to
traffic as well as enhancing safety to maintenance personnel was stated as a key
function within the Region by the stakeholders. Providing proper maintenance
equipment and resources as well as guaranteeing the safety of maintenance
personnel were stated as vital items.
User Service Mapping
User needs were mapped as closely as possible to the user services
documented in the National ITS Architecture. The mapping process ensures that
the stated user needs are supported by the National ITS Architecture. In many
instances, a user need may not always map directly to a user service in the
National ITS Architecture. New or updated user services may be added to the
National Architecture over time.

F. Functional Requirements
Functional Requirements are a description of the tasks or activities that are
performed by each system to provide the selected user services. The functional
requirements for the Region are defined and located in the Turbo Architecture
files submitted to the Iowa DOT.
G. Regional Architecture
The Appendix illustrates the MPOJC Regional ITS Architecture. The architecture
is based upon the inventory and Concepts of Operations identified in the
previous sections. Greater detail of the Architecture is provided electronically in
the MPOJC Regional ITS Corridor Turbo Architecture files submitted to the Iowa
DOT.
H. Maintenance Plan for ITS Architecture
The MPOJC Regional ITS Architecture Plan has been developed to ensure
comprehensive, cooperative, and continuing transportation planning activities
related to the implementation of intelligent transportation systems or ITS. It is
one component of the transportation planning process. As technologies develop
and evolve, so does this plan. This section outlines how the regional ITS
architecture plan is used and maintained.
Integration into Planning Process
The purpose of the MPOJC Regional ITS Architecture Plan is to outline both
technical and institutional linkages for the integration of transportation
technologies into the multi-modal transportation system. Ultimately, use of ITS
will reinforce the Region‟s vision of providing a safe, secure transportation
Regional ITS Architecture for MPOJC Region
17
network with seamless choices and services to the users, the traveling public or
meeting the needs of commerce.
The MPOJC Area Long Range Transportation Plan discusses ITS at the highest
level. Subsequently, the MPOJC Regional ITS Architecture Plan provides a
more complete definition of project requirements and enables the integration of
transportation technologies into network improvements. The regional ITS
document is viewed as a conceptual plan offering a framework for greater detail
these projects move toward implementation. This is similar to identification of
roadway projects in the Long Range Transportation Plan which require detailed
engineering analysis prior to construction. This ITS plan operates similarly where
project level architectures will be developed to refine details and specifications
conceived in this document. The project architecture will provide a concise
project description and identify dependence and relationships to other projects
and activities. Based on this analysis, the project scope will be refined to avoid
duplication and show project sequencing.
As projects develop from the regional ITS plan, potential funding sources are
identified and programmed for projects. ITS may be a component in the
evaluation and prioritization of projects vying for funds. If Federal funding is
used, the project moves into the Transportation Improvement Program then
proceeds toward implementation. The project will be identified in the
Transportation Improvement Program under plan justification as a documented
part of the MPOJC Regional ITS Architecture Plan.
Plan Maintenance Process
The regional ITS plan is a dynamic document. It will require changes with project
implementation, technology innovations and redirection of area goals and needs.
Formalizing plan maintenance will assure the ITS architecture for the MPOJC
Region is current and relevant. This will allow ITS stakeholders to effectively use
the document as a technical and institutional reference when implementing
specific ITS plans.
Plan maintenance relies on three critical elements:
Identification of maintenance roles and responsibilities;
Determination of maintenance schedule or cycle and process; and
Selection of sections or parts of the Plan to be maintained.
Roles and Responsibilities. ITS stakeholders in the MPOJC Region, with
facilitation by MPOJC, will be responsible for periodic updates of the regional ITS
architecture. As ITS evolves in the MPOJC Region and broadens
responsibilities, plan approval may need to be taken to the MPOJC
Transportation Technical Advisory Committee (TTAC) and the Urbanized Area
Regional ITS Architecture for MPOJC Region
18
Policy Board (UAPB) for approval as technologies begin to be planned and
deployed in the metropolitan area. MPOJC as the MPO will be responsible for
maintaining the MPOJC Regional ITS Architecture Plan document.
The TTAC board is responsible for reviewing changes and making updates to the
region‟s ITS architecture. The board‟s membership and function are outlined as:
Membership – Intelligent Transportation System (ITS) Stakeholders
(engineers, public works, public safety, planners) in Iowa City, Coralville,
North Liberty, University Heights and Tiffin along with the smaller Johnson
County communities, Johnson County, the University of Iowa, and
representatives of the Coralville, Iowa City, University of Iowa, and Johnson
County transit systems.
Function – To coordinate ITS planning and other transportation improvement
plans, and deploy these plans in the MPOJC Region.
Schedule and Process. On-going plan maintenance is important. The ITS
Architecture Plan may be reviewed as necessary to determine a need for
modifications or plan revisions. This plan maintenance process may occur off-
cycle of the Transportation Improvement Program (TIP) to identify projects that
may be moving forward into an annual element of the TIP. The MPO is also
responsible for plan maintenance, including review of upcoming deployment
activities, review of technology innovations, and status of area goals and needs.
The administrative procedures for initiating changes to the MPOJC Regional ITS
Architecture Plan will be classified as either an amendment or an administrative
revision. An amendment is the addition, deletion or significant modification of an
ITS stakeholder, ITS project or ITS project sequencing. An amendment relates to
a new ITS project that is expected to use Federal transportation dollars. An
administrative revision is a minor modification of an existing ITS stakeholder, ITS
project or ITS project sequencing or simple correction. In either case, the
requested change will be submitted in writing to MPOJC staff. An amendment
will be published and advertised consistent with the public involvement plan for
the TTAC.
Maintenance of Plan Content. Sections of the plan may be more dynamic than
others. The regional profile and geography may be less dynamic than the ITS
Inventory or Implementation Strategy. The MPOJC Regional ITS Architecture
Plan 2005 and associated Turbo-Architecture files will be used as the baseline
condition. Changes to the ITS Plan document, including the text, tables or Turbo
database files, including the 2014 update, will be identified as they occur.
Maintenance Summary. Plan Maintenance is summarized as follows:
Regional ITS Architecture for MPOJC Region
19
Revisions or amendments to the ITS Plan will be directed to the MPO and
will be facilitated by the TTAC;
Review of revisions and amendments to the ITS Plan will be reviewed by
for consistency, standardization and intergovernmental impacts/
coordination;
Revisions will be made at the recommendation of the TTAC and
amendments or significant plan revisions will be approved by the MPO
Board or at the time when the plan geography expands beyond the
metropolitan area.
Changes to the document and database (Turbo files) will be processed by
MPOJC as part of a formal update of the document.
I. Agreements
The list of agreements below was developed during the 2006 update to this
document. Any existing agreements for ITS applications, such as the GPS
agreement between the University of Iowa, Iowa City and Johnson County will
remain in place.
Agreement for Operation of Virtual TMC during off hours:
The Iowa DOT Oakdale Maintenance office will need to have an
agreement with the Joint Emergency Communications Center. This
agreement will include allowing Johnson County Sheriff‟s office access to
the Iowa DOT‟s ITS system to perform TMC operations during off hours.
Agreement for Access to the Camera Images:
The Iowa DOT Oakdale Maintenance office will need to have agreements
with the local communities that request access to the camera images from
the Iowa DOT‟s ITS system. This agreement will allow the local
communities to tie into the Iowa DOT‟s ITS system as it is designed at
their own expense.
Agreement for Use of ICN fiber optics:
The Iowa DOT will need to have an agreement with the Iowa
Communications Network (ICN) to allow joint use of existing ICN conduits
and/or use of fiber optic cable. This agreement may also allow the Iowa
DOT to access and splice into existing ICN conduit and fiber optic cables.
Agreement for Use of Local fiber optics:
The Iowa DOT Oakdale Maintenance office will need to have agreements
with the local communities that have requested access to the Iowa DOT‟s
ITS system for access and joint use of the local communities existing fiber
optic systems. This agreement will allow the local communities to have
access to the Iowa DOT‟s ITS system.
Regional ITS Architecture for MPOJC Region
20
Rapid Removal/Recovery Program Memorandum of Understanding
(MOU):
The Iowa DOT will need to have an MOU between all local agencies in
support of the Rapid Removal/Recovery Program.
In addition, new agreements for ITS projects will be handled on an as-needed
basis between stakeholders. Assistance may be provided by MPOJC staff.
J. Standards
There are numerous ITS Standards that may be employed to guarantee
interoperability and interchangeability of ITS equipment and processes used by
the stakeholders in the region. A list of applicable standards for assistance with
implementation of the outlined architecture is provided in the Turbo Architecture
files. Several of these standards have been approved and are being used
effectively. Others are dynamic and currently in review and update. It is the
intention of MPOJC that its member entities will adhere at the time planning and
implementation to the applicable standards set forth in the National ITS
Architecture.
