Tasker Road/Marcel Drive Signal Warrant Study
Marcel Drive Warehouse Property Frederick County, VA

SUMMARY
Overview
The subject site is a portion of the previous Eastgate
proposed Revised Master Development Plan (RMDP) 12-07
from October 2007 allowing the zoning for M-1 and B-2 uses
south of Tasker Road. The property is an 8.11-acre
assemblage of 2 parcels (76-A-48B and 76-A-53C) zoned M-
1 and is proposed as warehouse/office and outdoor storages
uses for a single tenant building with one access to existing
Marcel Drive (Va. Route 787), approximately 450 ft from the
Tasker Road (Va. Rte. 642) intersection. The site is shown in
the aerial view from the Frederick County GIS.
This warrant study summarizes the derivation of future 2027
traffic volumes forecast with the proposed development for
the Tasker Road/Marcel Drive intersection to satisfy the
previous proffers that require any new development along
Marcel Drive to complete a traffic study as part of Frederick
County REZ 002-97 (Parcel 76-A-53C), and REZ 004-97
(Parcel 76-A-48B, Parcel 1). The Eastgate Properties Revised Master Development Plan
approved with REZ 002-07 indicates that signalization of the Tasker Road/Marcel Drive shall
be by others, i.e., not by properties within the Eastgate Commercial Center.
Notwithstanding, this warrant study is provided to assure state and local agencies that the warrants for signalization
are not achieved and signalization of Tasker Road is not required with this site. The traffic forecasts used for the
warrant study are developed from 13-hour intersection turning movement counts conducted in August 2022 with
Frederick County Public Schools in session and includes growth on Va. Route 642 and trip generation for the
proposed site use.
The warrant analysis does NOT justify the installation of a new signal with the proposed site development. The
analysis was conservative using volume thresholds based on only one lane for the mainline and side street
approaches, not the existing two lanes. For Tasker Road with separate left and right turn lanes, the MUTCD allows
the warrant to be assessed with the mainline approach as 2 lanes. However, Pennoni used only 1 lane on the
mainline which reflects the single through lane on Tasker Road at the subject intersection, which reduced the
MUTCD volume thresholds from 430 veh per hour to 350 vph (for Warrant 1A). Also, 100 percent of northbound
Marcel Drive right turns were removed from the analysis, since the existing right turn volumes are lower than the
left turns on Marcel Drive to westbound Tasker Road. This methodology is more conservative by reducing the
volume thresholds for the peak hour and multi-hour warrant comparisons, and the signal is still not required.
The study notes that the subject site does not add sufficient trips
to the subject intersection to include signalization as a
mitigation requirement. Based on the future conditions with
the site, the subject intersection will operate at acceptable LOS
for the peak hours with the site unsignalized, without additional
geometric improvements. The intersection has adequate turn
lanes on Tasker Road and Marcel Drive to accommodate existing
traffic, growth, and site trips. With the site trips associated with
the use conservatively estimated at less than 300 vehicles per
day, the need for signal control is not warranted with the subject site.

To assess the 2027 traffic conditions at the subject intersection, the warrant study was prepared consistent with
Standard 4.0 of the VDOT guidelines in IIM-TE-387.1 as revised through November 2019.
Proposed Land Use Activities
Based on the initial concept development plan, the site densities reflect a proposed 25,000 SF two-story “flex-
office” style warehouse building with 15,000 SF of warehouse uses and 10,000 SF of office/support uses , as
summarized in Table 1.

10,000 gsf
Included at 25% of trips
The final site plan is expected to have a smaller building footprint, and reduced parking, but allow for possible
expansion in the future. However, the warrant study is based on the larger building size, with added trips to account
for outdoor storage. This methodology is conservative to maximize the site trips, by using a blend of office and
warehouse uses which approximates the ITE Trip Generation Manual general industrial trip rates (LUC 110) to
reflect typical M-1 zoning uses. Warehouse trip rates per 1,000 sf are less than the general industrial uses and
outdoor storage trip rates are not included in the ITE Manual.
Site Trip Generation
A summary of the peak hour and Daily trip generation from the subject development is shown by land use in Table
2, derived to reflect a “flex-office” type of use with a mix of office, warehouse, and light industrial uses as allowed
under the existing M1 zoning. Effective trip rates for the warehouse also were increased to reflect the ITE trip rates
per employee, which yielded a higher peak hour trip count in relation to the calculated trip per 1,000 gsf, to be
conservative. The proposed trips also reflect an increase in traffic by 25 percent from the ITE rates to account for
the outdoor storage activities associated with the site plan. A detailed deviation of the trip rate ranges and traffic
sensitivity is described in the proposed site traffic section.

TABLE 2: PROPOSED SITE TRIP GENERATION
Projected Traffic Conditions
The 2027 traffic volume forecasts show that the intersection with existing geometry and traffic control has sufficient
capacity to support the proposed development. A detailed description of the adequacy of the turn lanes is provided
at the Tasker Road/Marcel Drive Operations section of the future conditions analysis.
2027 Peak Hour and Daily Traffic Volumes
The peak hour and Daily traffic volumes for the subject intersection in 2027 with the proposed development are
shown in Figure 1 on the left. The projected total Daily traffic on Marcel Drive is estimated at 2,110 VPD, with 227
VPD or 11% of the Daily trips on Marcel Drive associated with the proposed site. Compared to the total intersection
volumes, the daily site impact is only 2 percent. The AM and PM peak hour impacts are 21 percent and 22 percent,
respectively, of the traffic on Marcel Drive and 6 percent and 4 percent, respectively, of the total intersection
volumes.
2027 Traffic Operations
The peak hour operations for the intersection with the 2027 traffic with the proposed development are summarized
in Figure 1 on the right. LOS is shown for the AM and (PM) peak hours for the controlled movements with existing
geometry and unsignalized conditions based on Synchro LOS outputs for a side-street stop-controlled intersection.

With growth and the site, the Marcel Drive link approaching Tasker Road operates at a LOS “B” in the AM peak an
at a LOS “C” in the PM peak hour unsignalized.
2027 Multi-Hour Traffic Volumes
Pennoni developed projected 2027 hourly intersection turning movement volumes for a 13-hour weekday period
with the proposed development to compare to the volume thresholds for Warrants 1, 2, and 3 from Chapter 4 of
the Manual on Uniform Traffic Control Device (MUTCD). The volumes by movement are summarized in Table 3.

MUTCD Warrants
A summary of the MUTCD warrants is included in Table 4. The volume thresholds for Warrants 1, 2, and 3 are based
on the number of lanes on the approaches and major street speed. Although the approaches are two-lane, one-
lane approaches were assumed for lower volume thresholds. Each approach has two lanes but only one lane was
assumed for warrant review to reflect through traffic capacity of Tasker Road. The existing number of lanes on the
major and minor street approaches are two single-lane major and minor street approaches, an 85th percentile speed
on the major street of 45 mph or greater (the posted speed limit is 45 mph), and a 100 percent reduction of NB
Marcel Drive right turns. It should be noted that the major and minor streets are 2-lane approaches, and the
assumption of single-lane approaches is conservative (i.e., the volumes requirements are higher for a two-lane
approach versus one lane). For Marcel Drive, Pennoni used the left turns, which are higher for the total approach
and for the peak hours between 8- 10 AM and between 2 PM and 5 PM, For the side street, the right turns are
typically reduced for potential right turn-on-red-movements if a signal was to be considered.
The review of the warrants is described in the analysis section, but typically VDOT prefers to use the 8 hour or 4
hour warrants for new signal installation. The VDOT ADT option scenario in Warrant 1 is used for planning purposes
if 8 hour turning data is not available. In this case the Warrant 1 threshold, the Daily Estimate option is satisfied for
the Daily estimates based on the likelihood of satisfying Warrant 1B, or “the Interruption of Continuous Traffic” at
the 70% percent threshold and the “Combination Warrant” at the 56 % threshold. Pennoni does not recommend
signalization is justified based on the Warrant #1 Daily estimate alternative methodology, so the “Not Applicable”
box is checked since:
• The peak hour LOS is acceptable,
• 8-hour traffic data is available,
• The MUTCD suggests that Warrant 1 A+B “Combination” only be used when alternative remedial
solutions to a signal as assessed.

The major and minor street adjusted volumes for the 2027 analyses are summarized in Table 5, with comparisons
to MUTCD Warrants 1A, 1B, 1C, Warrant 2, and Warrant 3 volume thresholds/criteria. Note that for Warrants 1A,
1B and 1C (Combination), 8 hours of volume satisfaction is required. For the subject intersection only 1-4 hours
are meet. For the Warrant 2, 4 hours of volume satisfaction is required, and only 2 hours exceed the MUTCD
threshold.

Access Spacing
VDOT Access Management spacing requirements on Tasker Road as a major collector with a design speed of greater
than or equal to 50 MPH are 360 ft for partial access (Type 4), 445 ft for full access/directional crossover (Type 3),
660 ft for unsignalized/full crossover (Type 2), and 1,050 ft for signalized (Type 1). The subject location is currently
a T-intersection and would be considered Type 3. It should be noted that there is an entrance stub at the
intersection opposite Marcel Road for a potential 4th leg, which would give the intersection a Type 3 designation.
The distances to existing and potential future adjacent signalized and unsignalized intersections are greater than
the minimums, as summarized in Table 6. Therefore, if a signal is warranted, waivers of the VDOT Access
Management standards would not be required for implementation.

INTRODUCTION
Marcel Dr Property LLC has proposed to develop the site with a maximum 25,000 SF flex-office type warehouse
building. The site parcels are identified by Frederick County PIN #’s 76-A-53C and 76-A-48B totaling 8.11 acres. The
site is currently zoned for M1 (light industrial district).
The subject signal warrant analysis was prepared to satisfy proffers that require new site plan submissions on
Marcel Drive to assess the need for a signal at the subject intersection. The site location is shown in Figure 2.
Figure 2: Site Location
The relevant proffer requirements excerpts are noted below, as it relates to the subject site:
Parcel 76-A-53 C: REZ 002-97

For the subject intersection location, signal control was associated with the development of
residential and commercial uses north of Tasker Road as part of the Tasker Woods rezoning
approval in 2006 (Frederick Co #09-06), to accommodate left turns out of the possible Tasker
Woods commercial use to eastbound Tasker Road.

Pennoni reviewed the archived PHR+A file and noted that the PHR+A Traffic Study “letter to S Eddy; An Addendum
to A Traffic Study Impact Analysis of the Tasker Woods”, dated July 11,2006 did include signalization at the location
to achieve overall side street acceptable conditions with a 4-legged intersection at Tasker Road and Marcel Drive.
The projected traffic volumes south of Tasker Road were estimated at approxima tely 1,440 vpd in the 2007 study,
with turns at less than 40 vph.
Methodology
To provide the technical support to satisfy the proffer, Pennoni utilized the following resources to develop the
multi-hour traffic forecasts for VDOT review. Pennoni reviewed the general methodology with VDOT Edinburg
Residency and Staunton District TE staff via a conference call on July 28, 2022 , after VDOT suggested a warrant
study might be required to process the pending site plan. While the methodology follows the VDOT guidance for
traffic analyses, the following technical assumptions were included in the subsequent analysis:
• Existing volumes are based on 2022 turning movement counts,
• Link volumes are oriented to the full hour times for the warrant analysis, even though peak times on Tasker
Road vary at 6:45-7:45 AM and 3:45-4:45 PM. This simplifies the review of future volume forecasts.
• Future year volume included 6.0% annual growth for Tasker Road throughs.
• The total daily and AM and PM peak hour site trips were based on a mixture of warehouse (LUC 150), small
office building (LUC 712), and effective light industrial (LUC 110) uses, to reflect the envisioned “flex-office”
use for the site. The non-peak hour site trips reflect the hourly percentage of daily trips diurnal curve for
Warehouse uses (LUC 150) from ITE. Site trip distributions were determined based on existing AM peak
hour inbound and PM peak hour outbound counts.
• Per the ITE and VDOT guidance, the daily traffic volumes were checked for warrant thresholds, but
recommendations are derived from the 8-hour volume review.
• Crash history was evaluated, but the warrant recommendations are derived primarily from the projected
volumes. A detail crash report review was not initiated as only 2 incidents were reported near the
intersection since 2015, and both involved a deer, which would not be correctable with signal control.
• 85% speed conditions were not verified for the 45 MPH posted speed limit on Tasker Road. However, the
lower volume thresholds in the MUTCD were used.
Roadway Context
The public street network in the vicinity of the site is summarized below, with the existing characteristics and road
functional classifications (same for VDOT and County):
• Tasker Road (VA Route 642) is an undivided 2-lane major collector that connects US Route 522 (Front Royal
Pike) in the east with VA. Rte. 37 at Interstate 81 exit 310 in the west. The speed limit is 45 MPH in the site
vicinity. The VDOT AADT was 9,200 VPD in 2021, based on published data.
• Marcel Drive is an undivided 2-lane local road with an assumed statutory speed limit of 25 MPH. It provides
access to a 106,300 SF US Department of Justice building and a 73,000 SF wholesale/supply store (Special
Made Goods & Services) and ends in a cul-de-sac 900 ft from Tasker Road. The VDOT AADT was 1,400 VPD
in 2021, based on published data from 2020. The 2014 ADT for Marcel Drive was 1,800 VPD.

Comprehensive Plan
The Land Use Plan in the County 2035 Comprehensive Plan, adopted November 10, 2021, envisions the site parcels
as Mixed-Use Industrial/Office, consistent with the existing zoning. As part of the Comprehensive Plan, the
Frederick County Road Plan envisions Tasker Road as a 4-lane divided improved major collector roadway and a 2-
lane undivided minor collector roadway on the opposite side of Marcel Drive that would meet Macedonia Church
Road to the north. The Frederick County Road Plan designations are shown in Figure 3A in the study area.

VDOT Functional Road Plan
The VDOT Functional Plan for this portion of Frederick County is excerpted in Figure 3B, which shows Tasker Road
as a Major Collector in the study area vicinity. The functional plan designation establishes the VDOT Access
Management requirements for median crossovers and traffic control.
Figure 3B: VDOT Functional Plan
Multi-Modal Access
At the subject intersection, no pedestrian access is provided. Bike lanes are not included in the existing roadway
sections. A 10 ft. wide ‘hiker-biker trail’ was proposed with Eastgate Commerce Center along the north side of
Tasker Road in lieu of sidewalks to connect with the future trail proffered as part of the Tasker Woods application.
No sidewalks exist on Tasker Road or Marcel Drive.
Future Transportation Improvements
No programmed improvements are envisioned at this location. The warrant study is done with T-configuration
without the planned Tasker Woods development by others to the north and without the Tasker Road widening to
a 4 lame divided section as planned.
EXISTING CONDITIONS
Traffic counts were collected for Pennoni on Tuesday, August 23, 2022, from 6 AM to 7 PM. The AM peak hour was
from 6:45 to 7:45 AM and the PM peak hour was from 3:45 to 4:45 PM. The traffic counts are included in Appendix
A to this warrant study. The hourly volumes are summarized in Table 7.
Total Trips for the 13 hours on Marcel Drive total slightly less than 1,100 vehicles, and link volumes on Tasker Road
are 6,170 vehicles for the 13 hour study period. 52 percent of the Marcel Drive volumes are oriented to the west.
Based on an assumption default of 80-85 percent of the total traffic occurring between 6 AM and 7 PM, the August

2022 counts with Frederick County schools in session would equate to approximately 1,300 VPD on Marcel Drive
and 7,700 vpd on Tasker Road west of Marcel Drive.

PROPOSED SITE TRAFFIC
The site development is proposed as a 25,000 SF “flex-office” type warehouse building in the M1 Light Industrial
district. The concept development plan shows 54 total parking spaces, loading docks, and assumes 14 employees
for the parking calculations as applied to the warehouse uses. The plan concept is anticipated to be reduced in
footprint for the final site plan, but the larger density was used for this analysis, to be conservative, and recognize
outdoor storage for the site.

The plan concept is anticipated to be reduced in footprint for the final site plan, but the larger density was used for
this analysis, to be conservative, and recognize outdoor storage for the site.
Trips are summarized in Table 8, based on the equations and averages in the ITE Trip Generation Manual, 11th
Edition (2021).

TABLE 8: SITE TRIP GENERATION
The trip table highlights the range of trips for the site noted that the average ITE rates for general industrial uses
would result in 122 Daily trips, with peak hour trips at 19-20 vehicles. The ITE Land Use Code (LUC) 110 is a general
rate which is the default rate for uses in the M-1 District. For this site, Pennoni looked at the individual
office/warehouse components, which would equate to 136 VPD using the ITE average LUC 150 (warehouse) and a
small office building (LUC 712). However, the warehouse trips were increased to the effective trips with 14
employees in the warehouse, per the parking tabs, to test sensitivity and increase the ADT to approximately 181
vpd. Additionally, to account for the outdoor storage space, Pennoni added a 25 percent increase to the proposed
site trips for the trips associated with the 2.5 acres outdoor storage area. Outdoor storage is not included in the
ITE Trip Generation Manual, so this additional traffic is shown in Table 4 as general industrial and would increase
peak hour trips by 9 vehicles and approximately 50 vehicles per day. The resultant Daily traffic of 227 VPD with 37-
43 peak hour trips would equate to approximately 85 percent of the Daily trips i the 25,000 sf building were
assumed as a small office (LUC 712).
Heavy Vehicle Trips
Given the proposed warehousing uses, trucks were assumed to comprise a significant portion of the site traffic,
which have different impacts on the study intersections than passenger vehicles. Therefore, truck percentages from
the ITE Trip Generation 10th Edition Supplement (February 2020) for the use with the highest percentages, which
was for the Warehouse use (LUC 150) at 13% in the AM peak hour, 15% in the PM peak hour, and 27% daily. The
truck percentages were applied to the capacity analysis. For the warrant analysis, the truck traffic is included in the
total assignments.

2027 CONDITIONS
PROJECTED 2027 CONDITIONS WITH SITE
Future 2027 base traffic volumes represent the future traffic in the study area, to reflect local through growth and
site traffic.
Ambient Growth
An annual growth percentage of 6.0% for Tasker Road was applied to the 2022 volumes and the additional through
hourly volumes projected in 2027 are summarized in Table 9. As part of the scoping , Pennoni has suggested a
robust 5 percent growth rate be used for the analysis, pending the review of the historical trends. However, the
published VDOT historical trends from 2011 through 2021 on Tasker Road average 6.1 percent per year with annual
growth averaging 6.5 percent per year in the last decade, with AADT changing from 5,100 in 2011 to 9,300 in 2021.

based on the derived AM and PM peak hour trip generation for the site as a mix of warehouse, office, and light
industrial uses to reflect the “flex-office” use envisioned for the site. Office uses have a larger spike in traffic during
the AM and PM peak rush times, due to their high proportion of employment trips, compared to warehouse uses
that have lower spikes and a more even distribution throughout the day. Therefore, using the office peak hour trips
for the AM and PM peak hours is conservative, while using the warehouse diurnal percentages during the non-peak
hours continue to represent the warehousing portion uses. Using the office peak hour trip generation results in 22
more trips (18 in, 4 out) during the 7-8 AM peak hour and 26 more trips (8 in, 18 out) during the 4-5 PM peak hour.
The ITE warehouse diurnal percentages used for the non-peak hours are shown in Table 11A. The hourly site trips
used in the analysis are shown in Table 11B.

Tasker Road/Marcel Drive Operations
Under existing conditions, the inbound lefts operate at LOS “A” and the outbound approach operates at LOS “B”
for the AM and PM peak hours. The left turn outbound operates at LOS “B” during the AM peak hour and at LOS
“C” during the PM peak hour while the right turn outbound operates at LOS “A” during the AM peak hour and at
LOS “B” during the PM peak hour. There is adequate storage for all 95th percentile queues during the AM and PM
peak hours, with all being less than 1 car-length (25 ft).
Under 2027 conditions with the proposed development, all the movements are projected to continue operating at
LOS “C” or better during the AM and PM peak hours and there will continue to be adequate storage for all 95th
percentile queues with the largest queue at less than 2 car-lengths (50 ft) for the AM and PM peak hours.
The LOS are shown graphically in Figure 1, for the 2027 operations with the Synchro analysis, attached as Appendix
B.
The geometry of the existing intersection is outlined in Table 14 below, with the future operations satisfying the
VDOT Road Design Manual (RDM) Appendix F turn lane criteria in Figure 3-1 of the RDM for the proposed traffic
conditions. The lengths of storage are adequate for rural design at 50 MPH higher, the turn volumes do not
approach the minimum criteria of 240 vehicles, and the left turn operation are at LOS “C” or better with the site
unsignalized. The right turn tapers for both direction on Tasker Lane are at approximately 150 feet, while 200 feet
is suggested for design speeds of 35 MPH or higher. However, with the longer storage length for the rights at 250
feet, the square footage of right turn lane + taper pavement at approximately 3,600 feet is equivalent to the current
VDOT guidelines. The Marcel Drive sections is widened to 2-lane outbound with over 375 foot storage, and
approximately 325 feet striped for a separate left turn lane, which is adequate for the maximum 2 car queue (1.3
vehicles) at LOS “C” in the PM peak.

2027 WARRANTS WITH PROPOSED SITE
The intersection volumes by hour for the warrant review is summarized in Table 3, with RTOR volumes adjusted
from the total volumes in Table 13.
MUTCD Volume Warrants
The MUTCD volume warrants are compared based on the number of vehicles per hour for the side street and the
total number of trips on the mainline volumes and compared to minimum thresholds. Table 15 below summarizes
the volume thresholds and the hours satisfied of volume thresholds for the 8-hour, 4-hour, and peak hour warrants.
The volume from Table 13 for the 13 hours of weekday data are compared to the MUTCD thresholds for 3 8 hour,

• Warrants based on 50 MPH mainline design speed.
• Warrant #2 and Warrant #3 are based on curves per number of lanes, assume 1 for major street and 1 for minor
street. Side street only include left turns on Marcel Drive for volumes.
MUTCD Warrant 1, Eight-Hour Vehicle Volume: Not Satisfied. The subject intersection was evaluated in accordance
with the guidance provided in MUTCD, Section 4C.02. Thresholds established for one lane of moving traffic on the
Major Street and for one lane on the Minor Street were applied to be conservative. Hourly volumes for Millwood
Pike were compared to the 70% thresholds established by MUTCD guidance based since posted speed at 45 MPH
would qualify for a reduction. An 85th percentile speed analysis was not performed. For the stand-alone warrant
under Condition A (Minimum Vehicular Volume), zero (0) analysis hours satisfies the criteria. For the stand-alone
warrant under Condition B (Interruption of Continuous Traffic), 2 analysis hours satisfy the criteria. The warrant is
met when either warrant condition is satisfied. Either warrant condition is met when eight (8) analysis hours satisfy
the criteria.
Further evaluation under this warrant allows for consideration of Condition A and Condition B in combination at a
20% reduction in volume thresholds. When analyzed under these criteria, one (1) analysis hour satisfies the
combination of Condition A or Condition B. The MUTCD notes that the combination warrant is only applicable after
adequate trial of other remediation measures.
The MUTCD Warrant 1 analysis thresholds are shown in Figure 4.

MUTCD Warrant 3, Peak Hour: Not satisfied. The subject intersection was evaluated in accordance with the
guidance provided in MUTCD, Section 4C.04. This guidance states that the peak conditions are only applicable for
installations in unusual cases that attract or discharge large numbers of vehicles over a short time. None of the
analysis hours out of the 13 available satisfy the criteria. The warrant condition is met when one (1) analysis hour
satisfies either category:
Category A. Stopped delay (not met)
• Total stopped time delay for minor street exceeds 4 vehicle hours on a single lane approach or 5 vehicle
hours for a two-lane approach (not met),
• Volume on the minor street exceeds 100 vehicles per hour on a one-lane approach or 140 vph for two-
lanes (not met),
• Total entering volumes exceed 650 vph for the 3-legged or 800 vph for 4-legged approach (not met); or
Category B. Volumes (not met)
• Volumes exceed applicable curve from MUTCD Figure 4C-3.
For the Future Year 2027 conditions with the Site activities, the peak-hour warrants are summarized in Figure 6 for
the subject intersection for the 4 busiest hours in terms of volumes for the second category. Warrants not satisfied

MUTCD Warrant #4, Pedestrian Volume: Not satisfied. Pedestrian activity is anticipated to be minimal at the
intersection with no pedestrian linkages on Tasker Road or Marcel Drive. Therefore, since pedestrian volumes need
to satisfy 75 total crossings per hour for four hours, or 93 crossings in a peak hour (with the 70% speed reduction),
the pedestrian activities will not satisfy MUTCD thresholds. The warrant is also not applicable within 300 feet of
alternative crossing, which is not applicable on Tasker Road.
MUTCD Warrant #5, School Crossing: Not applicable since the applicable warrant trigger is the trips generated by
the proposed development and total volume at the subject intersection. The nearest schools, Armel Elementary to
the north on US 522 and Robert E. Aylor Middle to the southwest on White Oak Road, are approximately a mile and
half a mile away, respectively (further by car). There is minimal residential development that would have to traverse
the subject intersection if walking to school. The great majority of residential developments are to the west on the
west side of White Oak Road.
MUTCD Warrant #6, Coordinated Signal System: Not applicable since the operations at the adjacent signals are not
part of the proffered warrant requirement. The distance between the adjacent signals is approximately 4,300 ft
and are not assumed to be coordinated and therefore, platooning between the intersection is not a concern.
MUTCD Warrant #7, Crash Experience: Not satisfied. Review of the Virginia Crash Data maps by Jurisdiction and by
route note only one incident in the influence area of the intersection since at least 2014. The incident was deer
related and resulted in property damage only. Crash data is summarized in Table 16, which shows that there are
not 5 or more crashes annually of the type susceptible to correction by traffic signal control. Alternative intersection
options and enforcement are suggested first to verify if crash frequency can be reduced.

MUTCD Warrant #9, Intersection Near A Grade Crossing: Not applicable, since no railroad crossings within 140 feet
of the intersection and volumes/distance combination plots from MUTCD 4C-9 /4C-10 not achieved.
ITE Daily Warrants
Based on Virginia Supplement to the MUTCD, the application of the Institute of Transportation Engineers' (ITE)
Manual of Traffic Signal Design, Daily warrant was checked for the future conditions. Pennoni has evaluated the
average daily traffic link volumes. An adjustment was made for speeds on Tasker Road for 45 MPH or greater for
70 percent volume threshold. NB Marcel Drive right turns were also discounted 100 percent to get 11,030 vpd for
the main street and 1,510 vpd for the minor street.
The results are included in Figure 9, which show that the continuous daily Condition B and the combination of
warrants A and B at 56% are satisfied. As noted in the chart, the Average Daily warrant should only be used for
when traffic counts ae not available, such as a future intersection. The results are not suggested as justification for
the recommendations at the subject intersection. Like the 8 hour warrants, the Daily warrant thresholds as a
combination of Warrants A and B (boxed in Orange) should only be used after consideration of other remedial
measures are considered.
Although not applicable since the intersection is existing, the future volumes satisfy daily Warrant 1B. However,
since the detailed 13 hour volumes are only satisfied for 2 hours (out of 8 minimum house) of future traffic
conditions with the site, the application of the Daily warrant threshold is not recommended for this intersection.

CONCLUSIONS
This warrant study has been prepared to satisfy the proffer requirements for the proposed subject
office/warehouse development as part of the overall Eastgate commercial/employment uses. The analysis reviews
the multi-hour, peak hour, and daily traffic volumes. Based on the forecasts, proposed geometry, operating
conditions, the future conditions do NOT satisfy signalization, based on the MUTCD warrants. With the site traffic
comprising only 4-6 percent of the total traffic counts at the Tasker Road intersection and peak hour operations are
acceptable with the site with the existing geometry with separate turn lanes, the site plan should not be required
to provide additional improvements.
