Vision
To create a comprehensive, integrated, and connected road network, accomodat-
ing mulitple modes of travel, to support sustainable growth and development and
enhance quality of life.
Transportation Network
The 587-mile metropolitan area roadway network is the backbone of the transportation sys-
tem in the urbanized area. The arterial street network provides multi-modal access to neighbor-
hoods, commercial and industrial areas, schools, and parks. Arterial streets are the main routes
for commercial deliveries, emergency service vehicles, school buses, and public transit vehicles.
Local roads provide direct access to households, carry the lowest volume of traffic, have the low-
est speeds, and tend to be most popular with pedestrians and bicyclists.
Arterial Streets
The MPOJC Arterial Streets Map (see opposite page) reflects the metropolitan area arterial streets
including the U.S. Highway, State Highway, and Interstate System, and shows where future arteri-
al street extensions are expected (the exact location will be determined through the design and
engineering process). Future arterial corridors are identified by metro area entities. The Arterial
Streets Map is approved by the MPOJC Urbanized Area Policy Board coincident with the adoption
of the LRTP.
85% of respondents to the LRTP online survey
rated the overall transportation network as fair,
good, or very good. (551 responses)

There are two types of bridge
deficiencies. A bridge deficiency does not
imply a bridge is unsafe.
Structurally-deficient - A bridge having
deterioration to one or more major
components, but the bridge is not unsafe.
Functionally Obsolete– The geometric design
of a bridge does not meet the current design
standards.
Functional Classification
Functional classification is a tool used to define
the role of roadways within the larger transpo-
ration network. Each classification fits within a
hierarchy based on the level of mobility and ac-
cess that the particular roadway is intended to
provide.
Roadways with higher classifications better
serve mobility and provide less access to in-
dividual properties, whereas roadways with
lower classifications provide greater access to
individual properties but less overall mobili-
ty. Vehicles are able to move with the highest
speeds and least delay on higher-order road-
ways, such as interstates, while bicyclists and
pedestrians tend to move with the greatest
ease on lower-order streets, such as local, and
collector streets.
Classification of Metro Area Roadways
The MPO works with local jurisdictions, the
Iowa Department of Transportation (DOT), and
the Federal Highway Administration (FHWA) to
determine the federal functional classification
of metro area roadways. Approximately 33% of
the metro area roadways are classified on the
Federal Functional Classification map (see left).
This designation is significant as federal fund-
ing can only be spent on roadways functionally
classified as collector or higher. The metro area
can have no more than 35% of total roadways
classified.
Status of the Metro Area’s Bridges
The Federal Highway Administration (FHWA)
has developed condition ratings to describe
overall condition of bridges. Across the nation,
bridge condition is determined by the lowest
rating of National Bridge Inventory (NBI) con-
dition ratings for the bridge deck, superstruc-
ture, substructure or culvert. Bridge condition
is classified in terms of good, fair and poor as
noted in the table below.
Of the nation’s 618,456 bridges, 45% are in
good condition whereas 7.2% are in poor
condition. Iowa ranks #2 in the nation for the
percentage of structurally deficient bridges:
19.1%. Iowa ranks #1 in the nation for the total
number of structurally deficient bridges with
4,571.
The map on this page shows the location and
condition of the 121 bridges within the metro-
politan planning boundary. Of the 121 bridges;
53 are in good condition, 59 are in fair condi-
tion and 9 are in poor condition (strcuturally
deficient).
Two of the most traveled structurally deficient
bridges in Iowa are located in Iowa City:
Gilbert Street over Ralston Creek - 14,500
daily crossings [slated to be replaced in FY2022 with
$1,000,000 in Surface Transportation Block Grant – High-
way Bridge Program federal funding.]

Pavement Condition
The condition of our region’s infrastructure
is monitored using a numerical rating called
Pavement Condition Index (PCI). PCI is a metric
developed by the Iowa DOT that accounts for
a pavement’s ride quality and the amount of
cracking, faulting, and rutting present. PCI rates
the condition of the surface of a road network
from 0-100, where 0 is poor and 100 is good.

PCI for State and Federal Highways:
Pavement condition data for state and federal
highways in Iowa is collected by the Iowa DOT
and is shown on the map to the left. The pave-
ment condition of all state and federal high-
ways in the metro area averages (77), which
means roads are generally in good condition.
This is up from the 2014 average of 70.

This analysis used 2020 PCI data to
identify the condition of the region’s
pavement.
Within the Metro Area, 97% of State and Federal High-
ways are in fair to excellent condition; 3% are are in
poor or very poor condition.
PCI for Local Federal Aid Routes:
Pavement condition for local roads, eligible for
federal aid, is collected through the Institute
for Transportation at Iowa State University (In-
Trans) and is shown in the map to the right.
The pavement condition of all Federal Aid eligi-
ble roadways is in fair condition averaging 34.
Within the metro area, 60% of local Federal Aid
routes are classified as being in fair or good
condition; which can be attributed to the re-
gion’s continued investment in the repair and
maintenance of our roadways. The region’s
pavement condition will be tracked over time
in order to measure performance and help pri-
oritize improvements.
Information on pavement condition by community
and for local streets can be found in the Supporting
Documents section of this plan.
NOTE: The PCI numbers obtained from the Iowa DOT
and inTrans are not comparable values as they are
derived from different equations.

Travel Demand Model
Travel demand models (TDM) simulate existing travel patterns and forecast future travel patterns
based on existing, committed, and planned system improvements and socio-economic data.
TDMs support the development of the long range transportation plan and provide an objective
tool for evaluating major infrastructure projects, traffic volumes, and delay. TDM’s are nationally
recognized tools used by nearly all MPO’s and DOT’s across the United States.
The Metropolitan Planning Organization of Johnson County (MPOJC), along with assistance of the
Iowa DOT, developed a TDM for the 2050 Long Range Transportation Plan. The MPOJC TDM was
built using the Iowa DOT’s Iowa Standardized Model Structure (ISMS).1 ISMS provides a standard-
ized yet scalable travel demand modeling architecture for use by all MPOs in Iowa. The MPOJC
TDM utilizes TransCAD as the software that performs the four-step modeling process of trip
generation, trip distribution, mode choice, and traffic assignment.
1. Trip Generation
Trip generation is the process of estimating the number of trip productions and attractions in
each transportation analysis zone (TAZ) based on the socio-economic activity within the zone.
The model relies on data about economic activity (housing units, building area, and land use
area) to predict transportation decisions and trip generation. This process is conducted inde-
pendently by type of trip purpose (school, work, etc.) and done for each discrete time period.
Input Data
Model development began with the preparation of socioeconomic and network data for the en-
tire metropolitan area. A few of the primary elements of the TDM include:
• Parcel data (housing units, building area, and land use area)
• U.S. Census data (housing and demographic data)
• Network data (lanes, posted speeds, status of roadway improvements)
Trip Purposes
Travel characteristics vary depending upon the reason the trip is being made. Some types of trips
can only fulfill the intended purpose of that trip at very specific locations, such as schools. Other
types of trips are less sensitive to the distance between the origin point and the choices of desti-
nation, such as work trips. As such, trips were simplified into 3 basic categories:
1. Home-based work – a trip between one’s home and workplace
2. Home-based non-work – a trip between one’s home and a location other than work, such
as shopping.
3. Non-home based – a trip that does not begin or end at home, such as a trip from work to
shopping
Time Period
Daily person trip activities and various network elements are subdivided into four time periods,
AM (6:00-8:59), Mid-day (9:00 AM – 2:59 PM), PM (3:00-5:59) and off-peak (6:00 PM – 5:59 AM).
Weekday and weekend travel are modeled individually.
Transportation Analysis Zones
A transportation analysis zone (TAZ) represents the geography within which economic activity oc-
curs that results in the movement of people and freight. Each TAZ includes base year population
and land use data. Local planners were asked to assign their jurisdictions’ anticipated population
and employment growth (reference land use maps/ pop growth pg) to the TAZs for years 2018
and 2050. TAZ boundaries are typically roads included in the network or natural features, such
as the Iowa River.
There are 850 TAZs ranging in size from individual blocks in the more densely populated areas
to several square miles near the periphery of the planning boundary. There are also 35 external
zones located where roads cross the planning boundary. The external zones are intended to
represent the traffic passing through the metropolitan area.
Person Trip Generation – Productions and Attractions
Each trip has two trip ends. The trip generation mode calculates trip ends separately: one end
is classified as a trip production and the other end is a trip attraction. When trips start or end
at home, the home end is defined as the production end and the other end is defined as the
attraction end.
Transportation Network
The model network includes all Federal Functional Classification (FFC) roads in the metropolitan
area as well as some additional local roads that are critical for connectivity. Roads are categorized
based on their capacity, speed of travel, number of travel lanes, existence of turn lanes and sur-
rounding land uses. Transit routes and stops were also included in the transportation network.
The model network is then used to simulate trips between the production and attraction pairs
of traffic analysis zones.
Transportation improvements (road and bridge infrastructure projects) not included in the 2018
base model were also stored in the transportation network file. MPO staff coordinated with local
entities to develop the list of projects to be included in the long-range transportation plan. The
improvements include anything from new roadways, additional or reduced capacity change, etc.

Person Trip Generation – Productions and Attractions

is classified as a trip production and the other end is a trip attraction. When trips start or end
at home, the home end is defined as the production end and the other end is defined as the
attraction end.
2. Trip Distribution
Trips are distributed across the region by way of a standard gravity model process. The gravity
model assumes that the amount of travel between TAZs is based on the relative attractiveness
between the origin and the destination.
3. Mode Choice
Includes specific transit route details, including each transit route, route stops, route headways
and access modes to and from transit.
4. Traffic Assignment
Traffic or route assignment is the process of estimating the traffic flows on a network. The pro-
cess evaluates the impedance along the possible combination of links to connect each trip’s
origin and destination, then assigns the trips to those links.
Model Validation, Calibration, and Reasonableness Checking
Each step in the ISMS recommended model architecture includes guidance on model calibration,
validation and reasonableness checks. Model validation is the comparison of a model to ob-
served data not directly used in the model development. Model calibration is the adjustment of
model constants to better replicate observed results. Model reasonableness is comparing model
outputs to expected results.
Limitations of the Travel Demand Model
Travel Demand Models (TDMs) are
best used for general indications of
traffic patterns. Traffic forecasts are
generated with the best information
available, but no model software can
predict future political, cultural, and
economic decisions including:
• Local decisions related to annex-
ation and zoning patterns;
• Private sector decisions on
where to locate high traffic
generation land uses;
• Cost of fuel; and
• Individual decisions of preferred
transportation mode.
Level of Service
Capacity needs for the Iowa City Urbanized Area were evaluated based on current conditions
(base year 2018) and anticipated future conditions (horizon year 2050). Level of Service (LOS)
was used to evaluate the delay vehicle drivers experience. The Iowa DOT and MPOJC have adopt-
ed LOS E as the design capacity for the purposes of vehicular traffic modeling and planning. LOS
E represents the “ultimate theoretical capacity” of roadways. As traffic approaches LOS E, drivers
experience congestion and delays, and some begin to divert to adjacent, less congested routes.
LOS uses qualitative measures that characterize operational conditions within a traffic stream
and perception of these conditions by motorists and passengers. The descriptions of individual
levels of service (A-F) characterize these conditions in terms of factors such as speed and travel
time, freedom to maneauver, traffic interruptions, and comfort and convenience.

GRIDLOCK
Bicycle and Pedestrian Level of Service
Level of Service (LOS) criteria for vehicles are
different from those for bicycles and pedestri-
ans. The LOS criteria for bicycles and pedestri-
ans considers conditions including pavement
width, number of travel lanes, traffic speeds,
average daily traffic (ADT), delay, presense of
heavy vehicles, corner circulation area, and the
presense of pavement markings.
MPOJC evaluates bicycle and pedestrian LOS at
the request of our member entities. This allows
for comparison of the experience of drivers,
pedestrians, and bicycles simultaneously.

transportation network by the year 2050. Un-
der these conditions, many roads across the
metro would be congesting or congested (6%
AM peak hour/ 9% PM peak hour).
During the AM peak hour, the corridors with
the greatest congestion include Hwy 218, In-

of Forevergreen Road.
Congestion occurs along the same corridors

If federal funding continues to be distributed to
the metro area for investment in the transpor-
tation network as expected, and planned road/
capacity improvement projects are able to be
completed, peak hour congestion in the metro
area would decrease.
The degree to which congestion is lessened is
marginal considering the metro area will con-
tinue to add people, jobs, and homes. This
growth contributes to increased vehicle miles
travelled on the major metro area roads.
As less than half of the committed and planned
projects (proposed to be completed by 2050)
are capacity or expansion related projects,
many of the major roads across the metro will
remain at their existing capacity levels but will
serve an increased number of vehicles.

Road and Bridge Infrastructure Successes 2018-2021
Between FY2018 and FY2021 over $19,725,000 in Federal Surface Transportation Program funds
were distributed through the MPO and invested in the metropolitan area road network.
Complete Streets
MPO communities have embraced the benefits of the adopted Complete Streets Policy. Road
projects now include sidepaths (8- to 10- foot sidewalks) to accommodate bicycle and pedestri-
ans and desinged with enhanced crossings at major intersections. Where right-way widths and
topography allow pedestrian bridges and overpasses allow for easy crossing of major roadways
such as I-80 and Hwy 965. Iowa City has expanded its on-street facilities with buffered bike lane-
sand turning boxes.
Roundabouts
To date, Coralville has constructed twelve roundabouts and anticipates a future roundabout
at 1st Avenue and Oakdale Boulevard. Both Iowa City and North Liberty have constructed five
roundabouts. Roundabouts are increasingly viewed as a safer and more efficient alternative to
traditional intersection traffic control such as stop signs or traffic signals. Roundabouts have
been proven to reduce collision fatalities by 90 percent and injury collisions by 75 percent at in-
tersections (FHWA & Institute for Highway Safety) while reducing the amount of delay that vehicle
drivers experience as it is not required to come to a complete stop unless a conflicting vehicle is
present.

Vehicle Miles Travelled Decreased in 2019
As the metro population increases, VMT is also expected to increase but that was not the case in 2019. Metro
Vehicle Miles Travelled (VMT) increased between 2016 and 2018 with a substantial increase between 2016 and
2017 (49,602 miles travelled). In 2019, VMT decreased from 705,937 to 702,664, which is the first decrease in
VMT since 2016 when VMT decreased by 9,968 as compared to 2015. While the decrease is marginal, it may
be a result of multiple factors such as people utilizing alternative modes of transportation (transit, walking, and
bicycling) or there being more direct routes between origins and destinations.
Coordination of Traffic Signals
The following metro arterial corridors received refreshed timings/cordination plans based on current traffic
patterns.:
• 2nd Street – Coralville
• Dubuque Street – Iowa City
• Highway 1/ Highway 6 – Iowa City
• Dodge Street – Iowa City
• Riverside Drive – Iowa City
• 1st Avenue - Coralville
This is an ongoing effort to reduce vehicular travel time and delays, especially during peak periods.
Pedestrian overpasses and underpasses like this one that
allows the sidepath on Oakdale Blvd. pass under Coral Ridge
Avenue help to make busy corridors more accessible to
bicyclists and pedestrians.
Roundabouts, like this one in Coralville, improve safety, promote lower speeds, reduce conflict points, and lead to improved
operational performace.

Road and Bridge Infrastructure Challenges
Aging Infrastructure
As the metropolitan area continues to grow, the transportation network must be con-
tinuously maintained and modernized. The emphasis on expansion of the road network
during the last half of the twentieth century overlooked the necessary to replace and
rehabilitate aging facilities and equipment. As population increases in the metropolitan
area, there is a higher demand placed on the roadway network, especially in outlying
areas. The challenge is to provide adequate capacity to provide a reasonable Level of
Service for vehicular traffic while also keeping the system in a state of good repair.
Bridges in the metropolitan area continue to age with 61% of bridges being built prior
to 1980. As bridges continue to age, they became a detriment to the greater transporta-
tion system causing delays and safety issues. Identifying funding to maintain the metro
area bridges in acceptable condition is an ongoing challenge.
Safety
Improving the safety of our transportation network is priority. Overall metro colli-
sions increased in the last five years (2016-2020) as compared to the 5 prior years,
though fatalities and serious injuries have decreased (156 between 2016-2020 and
181 between 2011-2015). The rate at which fatalities and serious injuries occur per
100 million vehicle miles traveled (HMVMT), has fluctuated between 4.1 at the lowest
(2013) and 6.2 at the highest (2012). As compared to the State, the rate of fatalities
and serious injuries per HMVMT has been lower on average (comparing 2011-2017).
In the Iowa City Urbanized Area, approximately 56% of collisions occurring between
2015 and 2019 involved a driver younger than 24. Comparatively, approximately 16%
of collisions occurring during the same time frame involved a driver over 65 years of
age. This accounts for 72% of all collisions. However, these two demographics have
drastically different driving behaviors and transportation safety needs.
Climate Change
Climate change should be considered from two different perspectives relating to transpor-
tation – how climate change affects the transportation network and how transportation con-
tributes to climate change.
How Climate Change Affects the Transportation Network
Climate change poses an immediate and long-term threat in terms of increased extreme
weather events that affect the reliability and capacity of the local transportation network. Cli-
mate change is likely to damage transportation infrastructure through higher temperatures
and more severe storms and flooding, affecting the reliability and capacity of the transporta-
tion system while also increasing the cost. [EPA Link Below].
The metropolitan area has been significantly affected by flooding of the Iowa River and its
tributaries in recent years, including a major flood in 2008 and several smaller flood events
in years following. Flooding results in road closures, damage to infrastructure, disruption of
traffic patterns, and an increase in travel times and VMT. The expectation is that the area will
continue to experience both small and large scale flooding events.
How Transportation Contributes to Climate Change
Besides being affected by climate change, transportation systems also contribute to changes
in the climate through emissions. Burning fossil fuels such as gas and diesel, release carbon
dioxide into the atmosphere. This build-up of carbon dioxide and other greenhouse gases
cause the earth’s atmosphere to warm and subsequently impact the climate.
Transportation activities are the largest source of emissions, accounting for 29 percent of to-
tal U.S. greenhouse gas emissions in 2019. From 1990 to 2019, transportation CO2 emissions
from fossil fuel combustion rose by 24 percent due in large part to increased demand for
travel. [Inventory of US Greenhouse Gas Emissions and Sinks: 1990-2019 – Data Highlights]

Fuel Costs and Revenues
The cost of fuel directly affects many facets of the transportation industry. For exam-
ple, when the cost of fuel fluctuates noticeably, driving behavior changes and creates
an immediate impact on the transportation system through variations in number of
miles driven and changes in mode of travel. As mentioned in the Passenger Trans-
portation chapter, the level of transit ridership in the metro has historically been cor-
related with the cost of gasoline. Annual ridership increased to more than 7 million
trips per year during the 2008 recession as gas prices rose to over $3 per gallon.
Such changes in behavior can also have more far-reaching impacts, as notable in-
creases or decreases in travel can affect transportation-related revenues such as
those derived from fuel taxes. Iowa fuel taxes make up approximately 45% of the
state Road Use Tax Fund (RUTF).
Fuel tax revenues are declining due to increaces in fuel efficiency and the growth in
the electric vehicle market. In December 2018, the Iowa DOT provided a report1 to
the state legislature on the potential impacts to the RUTF. DOT estimates predicted
a decrease in tax revenue of $7 million to $45 million by the year 2040. The DOT has
proposed a number of strategies to mitigate the loss of fuel tax revenue, including
surcharges on the purchase and/or increased registration fees for electric or plug-in
hyybrid vehciles. These fees and taxes would be structured to recoup comparable
charges to what vehicle owners/users would otherwise pay in fuel tax.

Eastern Iowa Electric Vehicle Readiness Plan
Electric vehicle (EV) technology and deployment have advanced dramatically in recent
years, creating opportunities to directly reduce emissions from the transportation
sector while providing additional economic and energy security benefits. Recognizing
the role that local and regional governments can take in enabling an electrified trans-
portation future, an increasing number of communities across the United States are
defining strategies to achieve a greater level of readiness for EVs, with a focus on
charging infrastructure to support these vehicles.
The Eastern Iowa Electric Vehicle Readiness Plan (EVRP) is a collective effort
of cities, counties, and metropolitan planning organizations (MPOs) of East-
ern Iowa. Its goal is to increase zero-emission vehicles as one of the available
solutions to while meeting the mobility needs of the region and donig so eq-
uitably.
Representatives from Cedar Falls, Cedar Rapids, Davenport, Dubuque, and
Iowa City (including MPOJC) served on the steering committee that worked
with ICF Consultants of Cambridge, Massachusetts to complete the plan. The
plan establishes:
• Strategies for increasing and leveraging local and regional investment
in electric vehicles and charging infrastructure, with a focus on equity.
• Best practices for education, outreach, and addressing barriers to elec-
tric vehicles adoption.
• Actions, policies, and programs that municipalities can enact at the local
level.
• Regional coordination strategies.

Alternative fuels
More than a dozen alternative fuels are in production or under development
for use in alternative fuel and advanced technology vehicles. Government and
private-sector vehicle fleets are the primary users for most of these fuels, but
individual consumers are increasingly interested in them. Using alternative
fuels and advanced vehicles instead of conventional fuels and vehicles helps
the United States conserve fuel and lower vehicle emissions. In Iowa, there
are 932 fueling stations that offer alternative fuels.
https://afdc.energy.gov/fuels/
[US Department of Energy; Office of Energy Efficiency and Renewable Energy]
The MPO assists with regional coordination for EV and au-
tonomous vehicle, and other advanced transportation tech-
nologies. MPO staff serve on regional and state committees
to ensure the successful adoption of these technologies.

Emerging Technologies
Autonomous and connected vehicles are still emerging technologies with their own challenges
and opportunities related to vehicle safety and efficiency. According to their Iowa in Motion Plan,
the Iowa DOT plans to develop an implementation-ready platform for connecting and guiding
automated vehicles. This platform will be based on high-definition dynamic mapping, predictive
travel modeling, and a cloud-based communication network. The effort will initially deploy tech-
nologies supporting autonomous vehiclesin the Iowa City-Cedar Rapids area. Additional deploy-
ments are planned for the Des Moines-Ames metropolitan areas, as well as I-35 and I-80 across
Iowa. MPOJC will be a part of these conversations and planning processes as they relate to the
corridors in the Iowa City metropolitan area.
Connected Vehicles (CV)
Intelligent transportation systems that use cooperative dedicated, short-range spectrum (also
known as vehicle-to-everything or V2X communications) provide the potential to prevent a sig-
nificant number of crashes and enhance the safety of our nation’s transportation system. When
integrated into a vehicle (cars, buses, trucks, bicycles, motorcycles, wheelchairs, etc.) or into in-
frastructure, this V2X communication capability offers a powerful 360-degree sensor of threats
and hazards along our roadways.
[https://www.transportation.gov/research-and-technology/how-connected-vehicles-work]
Automated Vehicles (AV)
Automated vehicle (AV) technologies have the potential to significantly re-
shape the transportation landscape. AVs use a combination of light detection
and ranging (LIDAR), global positioning systems (GPS), optical cameras, and
processing power to analyze the roadway and make decisions for the driver.
Fully autonomous cars and trucks will integrate onto U.S. roadways by pro-
gressing through six levels of driver assistance technology advancements in
the coming years (see image to the right).
Iowa has taken a leadership role in assisting with the study of AV technologies.
In 2016, the Iowa DOT agreed to transform the heavily used I-380 corridor,
between the Cedar Rapids and Iowa City metro areas, into a test site for AV
technologies
The National Advanced Driving Simulator (NADS) at the University of Iowa,
with the help of key partners in the public and private sector, is researching
how partially automated vehicles can provide transportation options for peo-
ple who may not be able to drive themselves, such as the elderly or those with
mobility or visual impairments. A partially automated vehicle will be travelling
along a set route through Hills, Riverside, Kalona, and Iowa City.
Potential benefits of automation include:
• Safety – Removing human error from the crash equation;
• Economic and societal – Reducing or eliminating vehicle crashes, thus
reduceing the associated financial costs ;
• Efficiency and convenience – Smoothing traffic flow and reduced conges-
tion, which in turn reduces the time people spend commuting;
• Mobility – Expanding mobility options for people with disabilities.
The U.S. Department of Transportation’s
Connected Vehicle program is work-
ing with state and local transportation
agencies, vehicle and device makers, and
the public to test and evaluate technol-
ogy that will enable cars, buses, trucks,
trains, roads and other infrastructure,
and our smartphones and other devices
to “talk” to one another. Connected ve-
hicles have the potential to significantly
reduce the number of fatalities and seri-
ous injuries caused by accidents on our
roads and highways.

CoViD-19 impact
Traffic Trends
The onset of COVID-19 impacted travel patterns and mode
choice in the Iowa City Urbanized Area beginning in March
2020 through May 2021 when traffic patterns began to nor-
malize. The Iowa Department of Transportation (Iowa DOT)
recorded traffic counts at their more than 120 automatic
traffic recorders (ATRs) across the state and the data showed
fewer cars travelling on all types of roads. Between March
2020 and August 2021, Iowa City municipal street and prima-
ry roads saw an average decrease in traffic of 15% as com-
pared to a 12% decrease on all State muncipal street and
primary roads. In May 2021, traffic volumes on Iowa City mu-
nicipal street and primary roads began to normalize or reach
levels pre-COVID-19, with traffic volumes being 3% lower
than the same month in 2019.

Project Selection
To determine what projects to include in the MPOJC 2050 Long Range Transportation Plan, MPO
Staff asked entities to submit capital transportation infrastructure needs (projects) for the years
2022-2050 to be considered for inclusion in the Plan. Communities were asked to include any
projects for which they anticipate potential use of federal funds. Communities did not include
highway or interstate projects in their jurisdiction (which the Iowa DOT would typically fund), proj-
ects that would be developer driven and funded, or projects expected to be exclusively locally
funded. Upon receiving each community’s list of priority projects, staff completed a preliminarily
screen of the projects to determine if they were eligible for inclusion using the following criteria:
• Is the project eligible to receive Federal funds such as Surface Transportation Block Grant
(STBG), Transportation Alternatives Program (TAP), and/or Federal Transit Administration
funding?
• Does the project comply with the adopted MPOJC Complete Streets Policy?
• Is the project located within the adopted MPOJC Planning Boundary?
• Is the community committed to providing necessary matching funds for the project?
Once all projects were screened, staff hosted a series of public input opportunities where the
public was invited to comment on the projects submitted. Opportunities included virtual meet-
ings and an online interactive map detailing each project with the opportunity for the public to
comment.
The projects were subsequently scored by staff using the Urbanized Area Policy Board approved
scoring criteria [reference or include here]. The scores and public input were then provided
to the Transportation Technical Advisory Committee (TTAC) and Urbanized Area Policy Board
who were responsible for ensuring the final project list was fiscally constrained using the MPO’s
forecasted federal transportation infrastructure budget for years 2022-2050. The final fiscally
constrained project list is available starting on page x.
