This letter is my request that you two commissions jointly request a traffic study by the
Montana Department of Transportation (MDT) to consider lowering the speed limit to 55 mph,
from 65 mph, on highway US 93 north of the intersection with Reserve Street.
Attached is a print of the guidelines that the MDT has for changing speed limit designations. It
starts with a request and support by City and/or County governments. (see highlighted portion
on page 4 of 5 attached.) I believe it appropriate that both governments address such a request
since sections of north US 93 are interspersed between City and County jurisdiction.
Since the new Costco store opened up, and the new signals at that intersection became
operational, traffic has slowed, and northbound traffic never reaches 65 mph by the Rose
crossing intersection, which also has traffic signals. The Tronstad intersection is scheduled for
traffic signals due to the new subdivisions in process north of Tronstad, between US 93 and
Whitefish Stage Road. That intersection will likely be realigned with Silverbrook Drive when the
signals are installed.
Just as traffic has slowed between Reserve and the Costco intersection, and it has slowed
between that intersection and Rose Crossing, it is reasonable to expect the traffic to also slow
from Rose Crossing to Tronstad/Silverbrook Drive when the new signals are installed.
Because southbound traffic from the Church Drive (a junior intersection) to Tronstad/Silverbrook
Dr will be subject to the control of future traffic signals at Tronstad, it is reasonable to expect
southbound traffic will also slow down.
Since north and south traffic is generally afforded the same speed limits, if the southbound
traffic from Church to Tronstad/Silverbrook is reduced to 55 mph the northbound traffic up to
Church should also be reduced to 55 mph.
A major consideration in the analysis of a speed study is the "85th percentile speed" (see page 3
of 5 in attachment) of existing traffic. Due to the addition of new traffic signals and the expected
traffic signals at Tronstad/Silverbrook the 85th percentile has undoubtedly been reduced. Yet,
with the current legal maximum speed of 65 mph, there are numerous drivers that are driving
well beyond the 85th percentile. And this is creating unsafe driving conditions.
If the speed limit is reduced to 55 mph, and a driver was lucky enough to hit every green light,
his total travel time from Reserve to Church would be increased 18 to 20 seconds (over 65
mph). This will not create a hardship nor even an inconvenience on any driver.
Attached are three graphs (data provided by MT DOH) showing # of accidents, # of vehicles involved
in those accidents and the number of personal injuries sustained on this section of roadway
from years 2000 to 2025. With increasing traffic projected, these numbers will undoubtedly
increase. Reducing the speed limit may well reduce future person injuries.
I ask each Commission to pass a resolution of support for the MDT to initiate a "Traffic
Investigation" to determine if a reduction of the speed limit on US 93 from Reserve to Church is
warranted.
Thank you all for your consideration.
Respectfully submitted,
Dennis Bar

Speed Limits
Speed limits are posted to protect the public by informing drivers of the authorized, allowable
speed. Common speed limits are typically statutory as stated in Montana Code Annotated
61-8-303. Speed restrictions.
Daytime speed limits are in effect from one-half hour before sunrise to one-half hour after
sunset. Nighttime speed limits are in effect at any other time.
The speed limits in Table 1 went into effect October 1, 2019. These speed limits apply
unless otherwise posted.

Speed limits are posted only after a traffic and safety engineering study has been conducted
and (where applicable) approved by the Transportation Commission.
Engineering Considerations
Before setting limits, a traffic investigator considers:
• the length and width of roadway,
• the roadway type and condition,
• the location of access roads and intersections,
• existing traffic control,
• sight distance,

To ensure a consistent approach to speed limits statewide, the traffic investigator also
considers nationally accepted principles.
Decisions about rational speed limits are based in part on something
called a speed study. During the speed study, data is collected at
select locations along the roadway. This data is then analyzed to
identify the 85th percentile —the speed at which 85 percent of the
people drove at or below during ideal conditions.
The 85th percentile speed is typically used as a starting point for
setting a rational limit and is considered to be the maximum safe
speed for that location.
"IF
orafific Investigation
An important part of a traffic investigation is the speed study. Drivers take into consideration
the conditions of the roadway environment when determining their comfortable driving
speed. Thus, the speed which the majority of the drivers consider prudent is an important
factor.
Roadway data is collected using automated traffic counters at select locations during ideal
driving conditions. A technical analysis is done to determine the 85th percentile. This 85th
percentile represents the speed of which people drive during ideal conditions. Experience
has shown that a posted speed limit near this value is the maximum safe and reasonable
speed most drivers will travel.

Concerns about posted speed limits are handled either by MDT or by your local city of
county governments. MDT handles requests when the roadway is state- or federally funded.
If you're not sure which agency has jurisdiction, you may contact MDT's Traffic and Safety
Bureau or your local District Office.

Kequesting a 5peeci 5tuay
All speed limit investigations are conducted in cooperation with local officials. The initial
request for a speed study may come from a concerned citizen, however MDT requires
individuals to work with their local government to demonstrate the Cif or County in question
sup1 p_ orts conducting a speed study.
Each request is placed on a list and processed in the order it was received unless a higher
priority is assigned to it.
How Long Does It Take?
The speed study typically takes 9-12 months to complete. This allows time for data collection
and a comment period before recommendations are presented to the Transportation
Commission for action (MCA § 61-8-309).
Frequently Asked Questions
If we put up_a reduced speed limit sign won't that slow traffic down?
Will raising the speed limit cause motorists to speed up?
Do local officials have any input on what speed limit(s) are set?
What areas are being studied?
