Reference: Traffic Signal Warrant Analysis – Davis Lane & East Valley Center Road
Project No. 22396
Dear Mr. Bernard:
The purpose of this letter is to provide a summary of a traffic signal warrant study
that has been completed for the Davis Lane & East Valley Center Road intersection in
Bozeman, Montana. The signal warrant study was requested by MDT as part of their
SIAP approval process. Data used for the analysis included 24-hour turning
movement and pedestrian counts, intersection crash history, and other related
information presented in the Turnrow Development Traffic Impact Study (Sanderson
Stewart, 2023) as well as additional information provided by the developer for Phase
1.1 of Turnrow Development.
Existing Site Conditions
East Valley Center Road (U-1211) is an east-west route classified as a principal arterial
by the City of Bozeman and a minor arterial by MDT. It connects North 19th Avenue in
Bozeman to Jackrabbit Lane south of Belgrade. Adjacent to its intersection with Davis
Lane, East Valley Center Road has a single thru lane in each direction and a posted
speed limit of 60-mph. Davis Lane (L-16-716) is a north-south route classified as a
minor arterial by the City of Bozeman and a local street by MDT. It currently extends
between East Valley Center Road and West Oak Street with plans to construct
connections to Fowler Avenue and reach Huffine Lane in the near future.
The intersection of Davis Lane & East Valley Center Lane is currently stop-controlled
on the south leg (Davis Lane), which currently experiences a moderate level of traffic.
East Valley Center Road experiences an elevated volume of commuter traffic, and
once the adjacent Turnrow Development is completed, both roads will carry a higher
volume of vehicular traffic. Figure A on the following page depicts the study area.

Existing Traffic Volumes
Weekday AM and PM peak hour turning movement counts were collected at the Davis
Lane/East Valley Center Road intersection on Tuesday, October 11, 2022 in support of
the Turnrow Development TIS. The weekday peak hour periods were found to occur
from 7:30 to 8:30 AM and 4:45 to 5:45 PM. Raw count data was adjusted for seasonal
variation using MDT seasonal adjustment factors. Figure A also shows the resulting
calculated peak hour turning movement volumes. Detailed traffic count data
worksheets are included as an attachment.
Existing Intersection Capacity
Existing Conditions (2022) capacity calculations were performed using Synchro,
Version 11, which is based on the Highway Capacity Manual, 6th Edition
(Transportation Research Board, 2016) methodologies. The intersection currently
operates at LOS D on the northbound approach in the PM peak hour, with a 95th
percentile queue of four (4) vehicles. The AM peak hour operates at LOS C or better.
Table A below shows the results of the Existing Conditions (2022) capacity
calculations, and capacity worksheets are attached.

Crash History Analysis
Historical crash data was obtained from MDT for the 5-year period from January 1,
2015 through December 31, 2019. Three (3) crashes were reported at the Davis
Lane/East Valley Center intersection during that timeframe. Two (2) were right-angle
collisions and one (1) was a rear end collision. All three (3) crashes occurred with wet,
snowy, or icy pavement conditions, two (2) were in the dark with no lighting, and one
(1) crash cited glare as being a possible contributing factor.
Trip Generation
The Turnrow Development is anticipated to add a substantial volume of trips at the
Davis Lane/East Valley Center Road intersection. The previously referenced TIS
utilized Trip Generation, 11th Edition, published by ITE to estimate site-generated
traffic for the new development. Full buildout of the Turnrow Development is
projected to generate 9,514 new daily external trips and Phase 1.1 is projected to
generate 958 new daily external trips. Approximately 40 percent of Phase 1.1 trips are
anticipated to utilize the Davis Lane/East Valley Center Road intersection.
Future Traffic Volumes
It was assumed that Phase 1.1 of the development would be occupied in 2026 for the
purposes of calculating future volumes for analysis. Projections for Phase 1.1 (2026)
were calculated by combining site-generated traffic assignments with existing traffic
volumes grown to the future year by applying a yearly background growth rate of 2.0
percent and including trips from several adjacent developments with similar
buildout timelines. The background growth rate was determined after reviewing
historical MDT traffic data. These projections are also shown in Figure A.

Future Intersection Capacity
Phase 1.1 (2026) capacity calculations show that, under existing stop control, the
Davis Lane/East Valley Center Road intersection is projected to operate at LOS E on
the northbound approach during the PM peak hour with a 95th percentile queue of
eight (8) vehicles. The northbound approach is projected to operate at LOS C in the
AM peak hour. Table B below shows the results of the capacity calculations and
worksheets are attached.
Signal Warrant Analysis
Traffic signal warrants were evaluated using criteria outlined in the Manual on
Uniform Traffic Control Devices (MUTCD), which presents several warrants that can
be considered based on traffic volumes, school crossings, crash history, and others.
For the purposes of this analysis, Warrants 4, 5, and 9 (Pedestrian Volume, School
Crossing, and Intersection Near a Grade Crossing) were not evaluated because there
are no pedestrians, schools, or railroad crossings at or near the study intersection.
Additionally, satisfaction of the Peak Hour warrant alone should not be considered as
warranting a signal, as it is primarily meant for application at office complexes,
manufacturing plants, or other high-occupancy vehicle facilities that attract or
discharge a large number of vehicles over a short time.
Existing Conditions (2022) and Phase 1.1 (2026) signal warrant results are shown in
Table C on the following page, and the analysis worksheets are attached. A traffic
signal is very nearly met with Existing Conditions (2022) volumes; the required 8th
hour for Warrant 1 is one (1) vehicle from being met and the required 4th hour for
Warrant 2 is just below the warranting graphed line. In the Phase 1.1 (2026) scenario,
Warrants 1, 2, 3, and 8 (Eight-Hour Vehicular Volume, Four-Hour Vehicular Volume,
Peak Hour, and Roadway Network) are all projected to be met.

Mitigation Alternatives
Sanderson Stewart evaluated traffic signal operations at the Davis Lane/East Valley
Center Road intersection and found that all approaches are projected to operate at
LOS B or better in the Phase 1.1 (2026) scenario with a traffic signal. It was assumed
that the lane configuration with a traffic signal would include separate northbound
left-turn and right-turn lanes, as well as a dedicated westbound left-turn lane. It was
also assumed that the speed limit on East Valley Center Road would be lowered to 55-
mph or less due to the installation of the traffic signal. The HCM does not recommend
that traffic signals are installed where speed limits are above 55-mph. The signalized
capacity results are shown in Table D below, and calculation worksheets are attached.

Conclusions and Recommendations
The preceding analysis has shown that traffic volumes at the Davis Lane/East Valley
Center Road intersection very nearly meet traffic signal warrants in 2022 and a traffic
signal is projected to be warranted after construction of Phase 1.1 of the Turnrow
Development in 2026.
Capacity is projected to deteriorate to LOS E on the northbound approach during the
PM peak hour in the Phase 1.1 (2026) scenario when evaluated with existing stop-
control. A traffic signal is projected to operate at LOS B or better on all approaches
during both peak hours in the Phase 1.1 (2026) scenario.
Based on the Existing (2022) and projected (2026) capacity and traffic signal warrant
analysis presented in this letter, it is recommended that a traffic signal should be
installed prior to or concurrently with development of Phase 1.1 of the Turnrow
Development. The speed limit on East Valley Center Road should also be lowered to no
more than 55-mph, as it is not recommended for signals to operate on roadways with
speeds higher than that.

This warrant is intended for application where the fact that school children (elementary through high school
students) cross the major street is the principle reason to consider installing a traffic signal. This warrant shall
not be applied at locations where the distance to the nearest traffic control signal along the major street is less
than 300 feet, unless it can be shown that the proposed traffic signal would not restrict the progressive movement of traffic.
Is the number of adequate gaps in the major crossing traffic steam during the primary crossing
period less than the number of minutes in that crossing period?N/A
Do 20 or more students cross at this location during the highest crossing hour?N/A
Warrant 5 Satisfied?N/A
Are any adjacent traffic signals located so far away that they do not provide a necessary degree of
platooning and/or progressive operation?No
Warrant 6 Satisfied?No
This warrant is intended for application where the severity and frequency of crashes are the principal reasons to
consider installing a traffic control signal
Have adequate trials of alternatives failed to reduce the crash frequency?N/A
Have at least one of the following conditions apply to the reported crash history:
1. Do the number of reported angle crashes and pedestrian crashes within a 1-year period
equal or exceed the threshold number in Table 4C-2 for total angle crashes and pedestrian
crashes?
2. Do the number of reported fatal-and-injury angle crashes and pedestrian crashes within a
1-year period equal or exceed the threshold number in Table 4C-2 for total fatal-and-injury
angle crashes and pedestrian crashes?
3. Do the number of reported angle crashes and pedestrian crashes within a 3-year period
equal or exceed the threshold number in Table 4C-3 for total angle crashes and pedestrian
crashes?

This warrant is intended for application where installation of a traffic signal could be justified in order to
encourage concentration and organization of traffic flow on a roadway network
Do two or more of the intersecting routes at this location have at least one of the following
characteristics:
A. It is part of the street or highway system that serves as the principal roadway
network for through traffic flow; or
B. It includes rural or suburban highways outside, entering, or traversing a City; or
C. It appears as a major route on an official plan.
Yes
Does this intersection have an existing or immediately projected total entering volume of a least
1000 vehicles during a weekday typical peak hour and have a 5-year projected traffic volume that
meets one or more of Warrants 1, 2, and 3 during an average weekday?No
Does this intersection have an existing or immediately projected total entering volume of at least
1000 vph for each of any 5 hours of a Saturday or Sunday?N/A
Warrant 8 Satisfied?No
This warrant is intended for application where none of the conditions described in the other eight traffic signal
warrants are met, but the proximity to the intersection of a grade crossing on an intersection approach controlled
by a STOP or YIELD sign is the principal reason to consider installing a traffic signal.
Does a grade crossing exist on an approach controlled by a STOP or YIELD sign whereby the
center of the track nearest to the intersection is within 140 feet of the stop or yield line?
No
During the highest traffic volume hour during which the rail traffic uses the crossing, does the
plotted point representing vehicles per hour on the major street and the corresponding vehicles
per hour on the minor-street approach that crosses the track fall above the applicable curve in
Figure 4C-9 or 4C-10 (whichever is applicable) for the existing combination of approach lanes
