EXECUTIVE SUMMARY
Knight E/A, Inc. (Knight) was retained by Encore Car Wash, LLC to prepare a traffic impact study for a
car wash to be located in the southwest corner of the intersection of US 30 with Spangler Road in
Plainfield, Illinois. The site is bounded by US 30 to the north, Spangler Road to the east, the Winding
Creek residential subdivision to the south, and the Crest Creek Plaza retail center to the west. The site is
proposed to provide one car wash tunnel with four pay stations/queuing lanes able to accommodate at
least 44 vehicles as well as provide 36 vacuum parking spaces and 12 regular parking spaces. Access to
the car wash will be provided via a right-in/right-out access drive off US 30, a full access driveway off
Spangler Road, and cross access to the Crest Creek Plaza. The Crest Creek Plaza access drive
currently provides outbound left- and right-turn lanes with a two-way left-turn lane on US 30. A portion of
this site will remain vacant for future development.
To understand and evaluate the traffic operations of the surrounding roadway network, the following
intersections were included in the study area.
US 30 with I-55 Frontage Road
US 30 with Spangler Road
US 30 with the Crest Creek Plaza Access Drive
Due to the COVID-19 Pandemic and “stay-at-home” order, Knight was unable to collect accurate data at
the study intersections. Vehicular, pedestrian, and bicycle traffic counts were obtained with IDOT and
Village permission from a previous traffic impact study for The Boulevard Development for the
intersection of US 30 with the I-55 Frontage Road. The unsignalized intersections were based on trip
generation data and adjusted 2020 traffic counts. Recommendations and vehicle trip generation from
The Boulevard traffic impact study were included in the analysis to reflect future conditions in the area.
Vehicle trips were then estimated for the car wash and distributed over the roadway network in order to
determine the projected traffic operations for the area.
The existing and projected traffic operations were analyzed using the Synchro/SimTraffic 10.0 traffic
capacity analysis and simulation software. Based on the results of the analysis and observations of the
study area, the following recommendations and conclusions were determined.
Due to the irregularities in traffic caused by the COVID-19 Pandemic and “stay-at-home” order,
the analysis utilized 2019 traffic counts and other methodology to reflect typical peak hour traffic
data.
Improvements/modifications recommended in the traffic impact study for The Boulevard
Development were utilized to analyze projected conditions. These resulted in acceptable Levels
of Service (LOS) and will adequately accommodate the projected traffic volumes in the area.
The previous recommendation to provide a southbound right-turn overlap phase at the
intersection of US 30 with the I-55 Frontage Road/Boulevard Access Drive (Village Boulevard)
conflicts with the need to accommodate U-turns during the eastbound left-turn protected phase.
In order to rectify this, the southbound right-turn overlap phase should be disabled or regulatory
signage ‘U-TURN YIELD TO RIGHT TURN’ (MUTCD R10-16) should be provided to require U-
turns to yield to right turning traffic.

June 2020
The provision of the two-way left-turn lane and platooning of traffic due to the coordinated signal
system along US 30 will improve the operations of unsignalized intersections under existing and
projected conditions.
Access to the site will be provided by a right-in/right-out access drive on US 30, a full access
drive on Spangler Road, and a cross-access connection to the Crest Creek Plaza full access
drive. All proposed access driveways will provide one inbound lane and one outbound lane with
outbound movements under stop sign control.
The access drives operate at acceptable levels of service. Benefits from dispersing the traffic
between its three access drives reduce delays and minimize queuing and blockage.
The site will accommodate approximately 44 queued vehicles within the staging area without
impacting internal circulation or the operation of any of the access drives. The site’s four pay
stations/queuing lanes will provide adequate capacity to prevent queues from spilling out onto the
internal circulation drives, US 30, or Spangler Road.
1.3 acres of the site west of the car wash will be developed at a future date. The assumed future
land use will be a 4,000 square-foot fast food restaurant. The traffic analysis shows that traffic to
and from the site can be accommodated. Should this vacant land be developed into another land
use other than a fast food restaurant, then further analysis should be considered.

1 – INTRODUCTION
Knight E/A, Inc. (Knight) was retained by Encore Car Wash LLC to prepare a traffic impact study for a
proposed car wash to be located on a portion of the vacant parcel in the southwest corner of the
intersection of US 30 (Lincoln Highway) and Spangler Road in Plainfield, Illinois. This development will
provide one car wash tunnel with four pay stations/queuing lanes able to accommodate at least 44
vehicles. It will also provide 36 vacuum parking spaces, and 12 regular parking spaces. Access to the car
wash will be provided via a right-in/right-out access drive off US 30, a full access driveway off Spangler
Road, and cross access to the Crest Creek Plaza. The Crest Creek Plaza access drive currently
provides outbound left- and right-turn lanes with a two-way left-turn lane on US 30. A portion of this site
will remain vacant for future development.
The purpose of this study is to determine the projected impacts on traffic operations and identify any
necessary improvements/modifications to the roadway network or traffic control. As a part of this study,
the existing roadway network surrounding the site was observed, quantified, and analyzed to determine
the operation at the study intersections during the weekday morning, weekday evening, and Saturday
midday hourly peak traffic volumes. New trips generated based on the size and characteristics of the car
wash were determined and assigned to the roadway network to evaluate future traffic conditions. This
report presents and documents the existing data utilized for the analysis, summarizes the evaluation of
traffic conditions on the surrounding roadway network, details the potential impact of the projected traffic
on the adjacent roadway network, and identifies recommendations to mitigate operational issues.
A map of the study location is presented in Exhibit 1.1 while Exhibit 1.2 shows an aerial of the study
area and identifies the intersections included in the analysis.

2 – EXISTING CONDITIONS
The study area and adjacent roadways were evaluated through field data collection and traffic counts.
Information regarding the characteristics and operation are based on field investigation, observations,
and published data. A detailed summary of the findings are as follows.
2.1 Study Area
The study area is generally located between the southbound I-55 ramps and Lily Creek along US 30 in
the Village of Plainfield. The US 30 corridor is primarily occupied by commercial uses and to the south of
the site is the Winding Creek residential subdivision. Immediately adjacent to the site is a Mobil gas
station and the Crest Creek Plaza retail center. In addition to multiple vacant units, Crest Creek Plaza
contains the following uses.
Absolute Integrated Health Center
Country Financial
Crest Rent-A-Car
Integrity In-Home Senior Care
Tax Service
The Plainfield 2491 Moose Lodge/Family Center
Hometown Pet Grooming
Med Spa
Immediately to the north of the site is the future site of the mixed use development known as the
Boulevard. This development will extend between US 30 and Renwick Road and contain a Costco, multi-
family residential, hotel, and other retail/dining uses. The Costco is currently under construction and
could potentially be completed by November 2020.
2.2 Existing Roadway Characteristics
A description of the existing roadway system within the study area is explained below and is illustrated in
Exhibit 2.1.
US 30 (Lincoln Highway) is an northwest-southeast principal arterial roadway generally providing two
lanes in each direction separated by landscaped medians, exclusive left-turn lanes, or a two-way left-turn
lane. It is under traffic signal control at its intersections with the I-55 Frontage Road and has a posted
speed limit of 35 mph. Spangler Road is under stop sign control at its intersection with US 30. US 30 is
under the jurisdiction of the Illinois Department of Transportation (IDOT). It should be noted that this
segment is not designated as a Strategic Regional Arterial (SRA). According to the 2019 data published
by IDOT, it carries an Average Annual Daily Traffic (AADT) volume of 22,400 vehicles.
I-55 Frontage Road runs parallel to I-55 between US 30 and Canton Farm Road. It generally provides
one lane in each direction with left-turn lanes at major intersections. At its signalized intersection with US
30, the Frontage Road provides a U-turn/left-turn lane and dual right-turn lanes. It has a speed limit of 35
mph, is under the jurisdiction of the City of Joliet, and carries an AADT of 10,600 vehicles.
Spangler Road is a northeast-southwest local roadway providing access to the Winding Creek residential
subdivision with one lane in each direction. At its intersection with US 30, a raised median restricts
movements to right-in/right-out only. Spangler Road is under the jurisdiction of the Village of Plainfield.

2.3 Traffic Count Data
Due to the irregularities in traffic caused by the COVID-19 Pandemic, Knight was unable to collect
accurate data at the study intersections. The following describes the sources and methodology for
collecting traffic data at each of the study intersections. Calculations are provided in the Appendix.
2.3.1 US 30 with I-55 Frontage Road
Permission was granted by IDOT and the Village of Plainfield to utilize existing traffic data from a
previous study in the area. Vehicle, pedestrian, and bicycle traffic data was obtained from the 2019 traffic
impact study completed for The Boulevard mixed-use development. This data was collected by KLOA,
Inc. on Tuesday, February 26, 2019 during the weekday morning (7:00 to 9:00 A.M.) and evening (4:00
to 6:00 P.M.) peak periods as well as on Saturday, February 23, 2019 during the midday (12:00 to 2:00
P.M.) peak period.
2.3.2 US 30 with Spangler Road
Traffic counts using Miovision Scout Video Data Collection Units were conducted at the intersection of
US 30 with Spangler Road on Thursday, May 12, 2020 and Saturday, May 9, 2020. The counts were
conducted during the weekday morning (7:00 to 9:00 A.M.) and evening (4:00 to 6:00 P.M.) peak periods
as well during the Saturday midday (12:00 to 2:00 P.M.) peak period. Since the pandemic has decreased
the amount of traffic on the roadways, particularly typical peak period commuting traffic, these counts
were increased proportionally and balanced to match the 2019 US 30 mainline traffic.
2.3.3 US 30 with Crest Creek Plaza Access Drive
Since most retailers are closed due to the state-wide “stay-at-home” order, traffic to and from the Crest
Creek Plaza was observed to be minimal. None of the uses within the Plaza were observed to be open.
In order to analyze this intersection, traffic was generated using the Institute of Transportation Engineers
(ITE) Trip Generation Manual, 10th Edition. The number of trips are estimated according to a vehicle trip
generation rate dependent on the size of each business. Given the variety of uses, Land Use Code 820:
Shopping Center was utilized. Table 2.1 shows the traffic estimated for the Plaza access drive. Traffic to
and from the access drive was assigned to the driveway in accordance to Exhibit 2.2, which is based on
existing traffic patterns and population density.

Note: ITE Trip Generation Manual used to estimate traffic for the approximately 25,000–s.f. Crest Creek Plaza access drive
based on the 10th Edition ITE Land Use Code 820: Shopping Center (Average Rate).
2.3.4 Overall Peak Hours
The result of the traffic counts indicate that overall peak traffic conditions of the roadway network take
place from 7:00 A.M. to 8:00 A.M. during the morning peak hour, 4:30 P.M. to 5:30 P.M. during the
evening peak hour, and 1:00 P.M. to 2:00 P.M. during the Saturday midday peak hour. It should be noted
that the pedestrian and bicycle traffic in the area was minimal. The existing weekday morning and
evening and Saturday midday peak hour traffic volumes are illustrated in Exhibit 2.3.

3 – PROPOSED REDEVELOPMENT AND PROJECTED CONDITIONS
This section of the report outlines the proposed redevelopment, summarizes site-specific traffic
characteristics, and identifies other characteristics impacting the analysis of future conditions.
3.1 Proposed Site and Development
The development will occupy the vacant parcel located in the southwest quadrant of the intersection of
US 30 with Spangler Road. As proposed, the site will contain a single car wash tunnel with four pay
stations/queuing lanes as illustrated in Exhibit 3.1. It will also provide 36 vacuum parking spaces, five
spaces for vehicle prep prior to the car wash, and seven regular spaces primarily for staff parking. In
addition, approximately 1.3 acres will be available on the west side of the site for an additional
development at a later date (not part of this development).
3.2 Site Access, Circulation, and Queuing
Access to the site will be provided via a right-in/right-out access drive off US 30, a full access drive on
Spangler Road, and cross-access to Crest Creek Plaza. The existing curb-cut located in the northwest
corner of the site will be removed. The Plaza Access Drive provides left- and right-turn lanes and one
inbound lane and will provide the only access for entering westbound traffic. Since Spangler Road and
the right-in/right-out access drive are restricted to right-turns only, outbound traffic exiting to the west
must do so via the cross-access or utilize the protected U-turn/left-turn phase at the intersection of US 30
with the I-55 Frontage Road. All access drives will provide one inbound lane and one outbound lane with
outbound movements under stop sign control. The cross-access will intersect the Plaza access drive
approximately 60 feet south of US 30 to minimize queuing conflicts and will result in a loss of
approximately four parking spaces from the Plaza parking lot.
Internal circulation drives will be provided along the exterior of the site. To minimize the impact of queued
vehicles on the site and surrounding area, the entrance to the car wash tunnel will be limited to the west
side of the site allowing for ample queuing space on site. Between the entrance of the tunnel and the
four pay stations, approximately 100 feet is provided for vehicles to queue without blocking the pay
stations. Beyond the pay stations, a staging area providing four queuing lanes just over 300 feet each
will accommodate approximately 44 total vehicles. Should an instance occur where queuing exceeds the
staging area, internal circulation will not be significantly impacted and will not conflict with US 30 mainline
traffic.

Exhibit 3.1 – Proposed Site Plan
US 30 / Spangler Road Car Wash Page 13
June 2020
3.3 Trip Generation, Distribution and Assignment
In order to determine the number of vehicles that will be generated by the redevelopment of the site, data
from the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition, was utilized.
The number of trips are estimated according to a vehicle trip generation rate based the use and size of
the car wash. To generate trips for the site, the ITE land use for Automated Car Washes (Land Use Code
[LUC] 948) was utilized based on the footprint of the car wash tunnel. However, since ITE does not
provide a morning peak hour trip generation rate, the number of trips for the time period are based on
one-half of the evening peak period rate.
Note that a number of the vehicle trips to and from the car wash will be from vehicles already traveling in
the area, particularly on US 30. These trips, known as pass-by trips, account for drivers attracted to the
site while already en route from one destination to another. They are particularly common during the
morning and evening peak periods when most drivers are commuting between home and work and can
stop at an additional destination without deviating from their existing route. While these trips will be
accounted for at the access drives, they will not add to the mainline traffic volumes.
Surveys of vehicle-related uses like gas stations typically result in average pass-by trip percentages of
60 percent or higher. Since ITE does not provide information for a car wash, a 50 percent pass-by
reduction was assumed to account for these types of trips already within the roadway network. Table 3.1
summarizes the trip generation and pass-by traffic anticipated for the car wash facility.

The existing traffic counts and proposed roadway network were utilized to determine the trip distribution
to and from the car wash for the projected trips, as previously described and shown in Exhibit 2.1. The
new trips were then assigned to the study intersections in accordance with the trip distribution, as shown
in Exhibit 3.2, while Exhibit 3.3 illustrates the pass-by traffic for the site.

3.4 Projected Traffic Conditions
The following describes factors that will impact the traffic operations in the future and the modifications to
the analysis to represent them under projected conditions.
3.4.1 Adjacent 1.3-Acre Site
To the west of the proposed car wash will be approximately 1.3 acres to be developed at a later date. In
order to more-accurately represent future conditions, additional traffic was generated for this site. Given
the size and current zoning of the site, it was assumed that a fast food restaurant would occupy this
space in the future. Traffic was generated for a 4,000-square-foot fast food restaurant with drive-thru (ITE
Land Use Code: 934) and assigned using the trip distribution (Exhibit 2.2). Similar to the car wash, fast
food restaurants also experience a substantial amount of pass-by trips so a 50 percent pass-by trip
reduction was taken, as seen in Table 3.2. Traffic to and from the potential restaurant is shown in
Exhibit 3.4.

Note: Restaurant size assumed to be 4,000 s.f., which is consistent with typical fast food restaurants.
3.4.2 The Boulevard Mixed-Use Development
As previously discussed, The Boulevard mixed-use development is currently under construction. A traffic
impact study (prepared by KLOA, Inc.) was performed in April 2019. Access to the development will be
provided to and from US 30 via its signalized intersection with the I-55 Frontage Road and a right-
in/right-out access approximately 600 feet west of the frontage road. The study analyzed the weekday
morning, weekday evening, and Saturday midday peak hours under existing and projected conditions.
Table 3.3 shows the traffic to be generated by the total development. Future traffic volumes were
projected to the Year 2026.

The traffic generated by the development and the following improvements/modifications identified in the
April 2019 traffic impact study were incorporated into this study.
US 30 with I-55 Frontage Road/Boulevard Access Drive (Village Boulevard)
o Modify intersection and traffic signal/timings to accommodate the fourth (southbound) leg.
o Restripe the eastbound approach to provide dual left-turn lanes and the northbound
approach to provide a through lane.
o Southbound approach will provide a six-lane cross-section striped to provide two inbound
lanes, dual left-turn lanes, a through lane, and a right-turn lane.
US 30 with Right-In/Right-Out Access
o Access will provide one inbound and one outbound lane with outbound movements under
stop sign control.
o The westbound approach will be restriped to provide an exclusive inbound right-turn lane
extending to the signalized intersection.
3.4.3 Background Traffic Increase
To account for traffic increases outside the study area not attributed to any specific development,
background traffic projections were developed for a “build plus five” design horizon year (per standard
practice). Based on Year 2050 forecasting from the Chicago Metropolitan Agency for Planning (CMAP),
a compounded growth factor of approximately 1.25 percent per year was applied to the 2026 projected
traffic volumes along all roadways within the study area. Therefore, existing traffic volumes were
increased by approximately nine percent.
3.4.4 Total Projected Volumes
Given the substantial provisions necessary to accommodate The Boulevard development, this study
replicated the Year 2026 projected conditions with and without the development of the subject site. Year
2026 No Build Conditions were determined by increasing existing traffic by the background growth factor
and adding the traffic and improvements/modifications recommended for The Boulevard in the previous
study, as shown in Exhibit 3.5. The new and pass-by projected traffic volumes from the proposed car
wash and potential fast-food restaurant use were then added to determine the Year 2026 Build
Conditions, as illustrated in Exhibit 3.6.

4 – TRAFFIC ANALYSIS AND RECOMMENDATIONS
This section of the report summarizes the process and results of the traffic analysis for the existing and
projected conditions during the weekday morning, evening peak hours and Saturday midday peak hour.
It will also provide recommendations to mitigate/improve upon conditions in the future.
4.1 Analysis Procedure
Traffic volume data was analyzed with the Synchro/SimTraffic 10.0 traffic capacity analysis/simulation
software in order to determine the quality of operation in the existing and proposed roadway networks.
Operation is characterized according to the amount of control delay at each approach and quantified into
a level of service (LOS). The LOS grades shown below, which are provided in the Transportation
Research Board’s Highway Capacity Manual (HCM), quantify and categorize a driver’s discomfort,
frustration, fuel consumption, and travel times experienced as a result of intersection control and the
resulting traffic queuing. A detailed description of each LOS rating can be found in Table 4.1. Table 4.2
presents the range of control delay for each LOS rating as detailed in the HCM. Because signalized
intersections are expected to carry a larger volume of vehicles and stopping is required during red time,
note that higher delays are tolerated for the corresponding LOS ratings. In order to accurately analyze
the signalized intersection, signal timings for each intersection were acquired. Based on the HCM
methodologies, capacity results for the existing and proposed signalized intersection are summarized in
Tables 4.3. Table 4.4 through 4.6 summarize the results for the unsignalized intersections.

4.2 Discussion of Operations
The results of the capacity analysis for existing conditions in the study area show that all intersections
operate at acceptable levels of service (LOS) and observations in the area generally reaffirmed these
results. Given the proximity of the traffic signals and platooning created along US 30 due to the Frontage
Road and Lilly Cache Road, turning movements at the unsignalized intersections often experience
minimal delay. The provision of a two-way left-turn lane at the intersection of US 30 with the Crest Creek
Plaza Access Drive reduces delay for outbound vehicles as well as the impact on US 30 mainline traffic.
Under No Build projected conditions, the provisions along US 30, particularly at its intersection with I-55
Frontage Road/Village Boulevard, will continue to adequately accommodate traffic through the
intersection while providing acceptable levels of service to the development traffic. Turning movements
may experience delay since they are protected-only phasing as well as the long cycle length and limited
green time. It should be noted that analysis of these conditions show that the protected westbound left-
turn movement operates at LOS E or F while the previous study cited LOS D or E. This is likely due to
the difference in study area and analyzed intersections. The previous study included the I-55 ramps to
the east of the Frontage Road, which would improve progression along US 30 at this intersection and
allow coordination with the off-ramps to improve delay for westbound traffic.
A modification is required to the projected conditions for the eastbound U-turn/left-turn. Given the need to
continue to provide U-turns at this intersection, a southbound right-turn overlap phase would conflict with
the U-turn/left-turn protected phase. To correct this, the right-turn overlap phase can be disabled or a ‘U-
TURN YIELD TO RIGHT TURN’ sign (MUTCD R10-16) must be provided. This would require U-turn
movements to yield to the southbound right-turn movement during the protected phase. Due to
limitations in analysis software, this intersection was analyzed without the right-turn overlap phase.
Requiring U-turns to yield would ultimately reduce capacity and increase delay for the U-turn/left-turn
movement.
Year 2026 Build Conditions add the proposed car wash and potential restaurant traffic, resulting in
minimal increases of delay and queuing. The multiple ingress and egress alternatives to the site allow
access drives to adequately accommodate traffic to and from the site and does not significantly impact
the existing operation of Spangler Road or the Crest Creek Plaza Access Drive. The operation of the
Plaza Access Drive is improved given the ability to perform U-turns at the signalized intersection,
particularly during peak periods. Queuing at the Plaza Access Drive will not regularly impact the
operation of the internal cross-access intersection given the northbound 95th Percentile Queue is less
than two vehicles.
4.3 Proposed Circulation and Queuing
Overall, the proposed driveways will provide adequate access to the car wash site. As previously
described, the development will provide queuing for a total of 44 vehicles. The staging area will be
accommodated internally to the site without conflicting with the internal circulation or impacting
operations on the surrounding public roadways and will adequately accommodate the typical demand at
the site. Appropriately-located vacuum and prep parking spaces will minimize the congestion within site.

5 – CONCLUSIONS AND RECOMMENDATIONS
Based on Knight’s review of the proposed car wash as well as the existing and future traffic conditions in
the area, the following conclusions and recommendations are provided.
Due to the irregularities in traffic caused by the COVID-19 Pandemic and “stay-at-home” order,
the analysis utilized 2019 traffic counts and other methodology to reflect typical peak hour traffic
data.
Improvements/modifications recommended in the traffic impact study for The Boulevard
Development were utilized to analyze projected conditions. These resulted in acceptable Levels
of Service (LOS) and will adequately accommodate the projected traffic volumes in the area.
The previous recommendation to provide a southbound right-turn overlap phase at the
intersection of US 30 with the I-55 Frontage Road/Boulevard Access Drive (Village Boulevard)
conflicts with the need to accommodate U-turns during the eastbound left-turn protected phase.
In order to rectify this, the southbound right-turn overlap phase should be disabled or regulatory
signage ‘U-TURN YIELD TO RIGHT TURN’ (MUTCD R10-16) should be provided to require U-
turns to yield to right turning traffic.
The provision of the two-way left-turn lane and platooning of traffic due to the coordinated signal
system along US 30 will improve the operations of unsignalized intersections under existing and
projected conditions.
Access to the site will be provided by a right-in/right-out access drive on US 30, a full access
drive on Spangler Road, and a cross-access connection to the Crest Creek Plaza full access
drive. All proposed access driveways will provide one inbound lane and one outbound lane with
outbound movements under stop sign control.
The access drives operate at acceptable levels of service. Benefits from dispersing the traffic
between its three access drives reduce delays and minimize queuing and blockage.
The site will accommodate approximately 44 queued vehicles within the staging area without
impacting internal circulation or the operation of any of the access drives. The site’s four pay
stations/queuing lanes will provide adequate capacity to prevent queues from spilling out onto the
internal circulation drives, US 30, or Spangler Road.
1.3 acres of the site west of the car wash will be developed at a future date. The assumed future
land use will be a 4,000 square-foot fast food restaurant. The traffic analysis shows that traffic to
and from the site can be accommodated. Should this vacant land be developed into another land
use other than a fast food restaurant, then further analysis should be considered.

Most (if not all) businesses within the approximtely 25,000-s.f. Plaza are closed due to Pandemic. Therefore, traffic was
generated using the ITE Trip Generation Manual, 10th Edition to replicate traffic in and out of the Crest Creek Plaza
Access Drive.
Note: ITE Trip Generation Manual used to estimate traffic for the approximately 25,000–s.f. Strip Mall Driveway based on
the 10th Edition ITE Land Use Code 820: Shopping Center (Average Rate).
