EXECUTIVE SUMMARY
The US 20 corridor between Chester and the Montana state is approximately 53 miles long and serves
multiple purposes that are of importance to the local, regional, and national economies. During the
summertime, thousands of tourists use the corridor while traveling to and from Yellowstone National
Park, the famous fly fishing destination of the Henrys Fork River, Harriman State Park, Henrys Lake State
Park, Mesa Falls, and other recreation destinations. In the winter, the corridor serves as an alternate
route to I-15 for commercial vehicle traffic traveling to and from I-90, the longest Interstate Highway in
the country. In fact, according to ITD staff, US 20 from Idaho Falls to Montana carries the greatest
amount of freight traffic of all non-Interstate Highways in the state of Idaho.
ITD has previously rebuilt US 20 south of Chester as a four-lane divided highway with a mixture of at-
grade and grade-separated intersections. However, north of Chester, US 20 is still a rural two-lane
highway. From 2010 to 2014, there were over 430 reported crashes on this rural section of highway,
resulting in an estimated economic cost of about $50 million. Further, summertime peak traffic is nearly
four times that of wintertime traffic volumes, leading to traffic congestion that only needs to be
mitigated for a couple months of the year.
This report builds on the US 20 Corridor Plan: Ashton to Montana State Line to lay out a vision for US 20
that will reduce crashes and peak traffic congestion without incurring the expense and impacts of
constructing a four-lane divided highway. This vision includes continuous alternating passing lanes in
both directions (also called a “2+1” configuration, see Figure EX 2) and wider shoulders, as shown in
Figure EX 1. Examples of sections of US 20 with passing lanes and shoulder are shown below.
Frequent Passing Lanes in Alternating Directions and Wider Shoulders is the Recommended Long-Term Configuration

When implemented, this configuration is expected to have two primary benefits:
1. Reduce crashes by approximately 25-30%, resulting in annual savings of $700,000 - $1.35 million
per year in crash costs (see Figure EX 3).

2. Long long-term efficient movement of motor vehicle traffic, resulting in people spending about
the same time following other vehicles 20 years from now, when traffic volumes are projected to
be 60% to 100% higher than they are currently, as they do today (see Figure EX 4).

INTRODUCTION
The approximately 53 miles of the US 20 corridor between Chester and the Montana state line serves
multiple purposes that are of importance to the local, regional, and national economies. During the
summertime, thousands of tourists use the corridor while traveling to and from Yellowstone National
Park, the famous fly fishing destination of the Henrys Fork River, Harriman State Park, Henrys Lake State
Park, Mesa Falls, and other recreation destinations. In the winter, the corridor serves as an alternate
route to I-15 for commercial vehicle traffic traveling to and from I-90, the longest Interstate Highway in
the country. In fact, according to ITD staff, US 20 from Idaho Falls to Montana carries the greatest
amount of freight traffic of all non-Interstate Highways in Idaho (Reference 1).
PROJECT PURPOSE AND BACKGROUND
Recognizing the importance of US 20, the Idaho Transportation Department (ITD) is evaluating how to
cost-effectively improve safety and provide for the long-term movement of people and goods along the
corridor. ITD has previously rebuilt US 20 south of Chester as a four-lane divided highway with a
mixture of at-grade and grade-separated intersections. However, north of Chester, US 20 is still a rural
two-lane highway. Given that existing and projected traffic volumes are lower north of Chester, a four-
lane roadway in this northern section may not be a cost-effective solution, while maintaining the
existing two-lane rural section may not meet future needs. Therefore, this study evaluates several
options for reducing crashes and providing for efficient long-term traffic flow that are likely to be less
expensive than building a four-lane divided highway along this section of US 20 shown in Figure 1
(approximately mileposts 353 to 406).
This report summarizes the traffic safety and operations elements of the Corridor Study Tasks 3 and 4
of the US 20 North Safety Corridor Planning Process. This study updates and expands upon the traffic
safety and operations evaluation conducted for the 2006 US 20 Corridor Plan: Ashton to Montana State
Line (Reference 2) and identifies potential improvements for the corridor to be considered in the future
Corridor Plan Tasks 5 and 6. The safety analysis completed for this report is data-driven, focusing on
solutions with known, quantifiable benefits and using analysis procedures from the Highway Safety
Manual (HSM, Reference 3) to the extent practical.
DATA COLLECTION
Data has been collected for this project in order to review the existing roadway characteristics, analyze
crash data using the predictive method from the Highway Safety Manual, and analyze traffic operations
along the corridor. All analyses conducted for this study are at a planning level and are not based on
detailed field measurements. Most data used in these analyses has been taken from ITD’s IPLAN
website (http://iplan.maps.arcgis.com/home/) or provided by ITD District 6 or Headquarters staff. Data
collected by KAI includes:

ROADWAY SUMMARY
This section of US 20 is generally a two-lane rural highway with paved shoulders varying in width from
approximately 0 to 8 feet. Passing lanes are provided in certain locations, typically as climbing lanes on
steep grades, as shown in Figure 1. There are about 13.4 miles of northbound passing lanes and 3.4
miles of southbound passing lanes, representing coverages of approximately 25% and 6% of the
corridor, respectively. Center-turn lanes are provided in some areas with higher access densities,
including through Ashton and commercial areas of Island Park.
Figure 1 also shows the approximate roadway grades throughout the corridor. The southern end of the
corridor (i.e., south of the Henrys Fork River at milepost 363 through Ashton to Chester) travels through
relatively level terrain. North of milepost 363, the highway climbs into the mountains where the terrain
is generally rolling as it passes through the Henry’s Fork and Island Park calderas. North of Henry’s Lake
the highway climbs again to the Montana border at the Continental Divide.
OTHER ONGOING PROJECTS
At the writing of this report, there are at least two other ongoing projects related to safety and traffic
operations on this section of US 20:
ITD District 6 Wildlife Study - This project is examining wildlife migration and vehicle crash
patterns along the same segment of US 20, as well as on State Highway (SH) 87 and
developing recommendations to mitigate animal crashes along the corridor.
US 20, Jct SH 87 to Montana State Line (Targhee Pass Concept Study) – This project is
evaluating design options for US 20 from its intersection with SH 87 to the Montana state
line. The early recommendation from a traffic study completed for this project is for an
eastbound climbing lane on US 20 (Reference 4).
ORGANIZATION OF THE REPORT
The remainder of this report is organized as follows:
Section 3 – Safety and Operations Analysis – Describes the existing roadway and crash
trends and the existing and projected future traffic operations.

SAFETY AND OPERATIONS ANALYSIS
This section summarizes the safety and operations analysis along the study section of US 20. Included in
this section are:
An analysis of traffic operations along the corridor under existing and future-year 2036
conditions
A review of historical crash data, including an analysis of the data using methods from the
Highway Safety Manual
TRAFFIC OPERATIONS
The traffic operations evaluation identifies the level of improvements that will be needed to
accommodate projected traffic growth on the corridor. Traffic operations were analyzed along US 20
using the two-lane highway analysis method from the Highway Capacity Manual 2010 (Reference 5).
Level-of-service (LOS) for two-lane highways is primarily based on the need for and availability of
passing opportunities (i.e., average travel speed and percent time spent following are the two
performance measures for US 20). The availability of passing opportunities was estimated for this
analysis using aerial imagery.
Existing Operations
Traffic volumes on US 20 are highly seasonal, as shown in Figure 2.
Figure 2 Year 2015 Traffic Volumes by Month (ATR #32 - Ashton)
This analysis captures the summer recreation period by analyzing the 30th highest hour. Volumes

IPLAN by using data from ITD’s automatic traffic recorder (ATR) #32 (Ashton), which is located on US 20
at approximately milepost 377. The results of this analysis are shown in Figure 3, along with the
location of existing passing lanes. Appendix “A” contains the volume data for each segment.
Projected Year 2036 Operations
Year 2036 traffic volume projections were provided by ITD staff. These daily volumes were converted to
estimated future 30th highest hour volumes using the same factors as in the existing conditions analysis.
The results of this analysis are shown in Figure 3.
Many segments that are projected to operate at LOS “D” or worse in the year 2036 lack passing lanes in
one or both directions. Adding passing lanes to many of these segments improves operations in most
cases to LOS “B” or “C.” These are the target levels of service for new arterial roadways in rural rolling
and rural mountainous areas, respectively, in the current ITD Roadway Design Manual (Reference 6).
Comparison to 2006 Study
The preliminary operations results summarized previously are similar or worse than the results from
the 2006 corridor study. This is likely due to two factors:
1. Traffic volumes have increased by about 30% on this section of US 20 since the previous study’s
analysis was completed.
2. The 2006 study used a lower volume than the 30th highest hour due to the seasonal nature of
the roadway. The analysis shown in this memorandum uses the 30th highest hour.

CRASH ANALYSIS
ITD provided crash data for the most recent five years for which data is available, 2010-2014, along US
20 and at select intersections. The crash data is summarized by segment in Appendix “A” and the raw
crash data provided by ITD is included in Appendix “B.”
Based on this data, the US 20 study corridor experienced an average crash rate of approximately 116
crashes per 100 million average vehicle miles traveled (AVMT) during this time period. This rate is
approximately 35 percent higher than the average rate for rural roadways in Idaho, which includes both
highways and local roads. It is also lower than the average rate in Idaho for US and State highways, but
those averages include urban and multi-lane highways, which are not directly comparable to this
corridor (Reference 7).
In order to identify the most effective improvement strategies, the analysis of the US 20 crash data
includes a review of existing crash data trends for the corridor, including at the selected intersections,
and an analysis of crash rates using the Highway Safety Manual.
Corridor-wide Crash Trends
Corridor-wide crash trends with respect to severity, road surface condition, and crash type are
summarized in the following sections.
Severity
Figure 4 summarizes crashes along the corridor by severity.
Figure 4 Crashes by Severity (2010 – 2014)
Just over one-quarter, approximately 27%, of all crashes on US 20 resulted in an injury or fatality. This
percentage is generally similar to, though slightly lower than, the statewide average of approximately
35% injury and fatal crashes for rural roads (Reference 7).
These crashes have a significant financial impact. Based on the economic cost of crashes contained in
ITD’s 2014 crash report (Reference 7), the estimated economic impact of all reported crashes along this
section of US 20 from 2010-2014 is approximately $50 million dollars.

Weather
Road surface conditions can be a contributing factor to crashes,
particularly in areas prone to winter weather. Slick road surfaces can
result in higher crash rates than would be expected and weather-related
crashes may be better mitigated by operational improvements (e.g.,
snowplowing, de-icing), as opposed to geometric improvements. Figure 5
summarizes crashes by reported road surface condition.
Figure 5 Crashes by Road Surface Condition (2010 – 2014)
Over half, approximately 55%, of all crashes are reported to have occurred when there was some type
of winter weather roadway surface (i.e., ice, snow, or slush).
Weather-related crashes can fluctuate based on changing weather conditions (e.g., a snowy year
compared to a dry year) and based on changes in maintenance practices, which we understand ITD has
done recently. Figure 6 shows the crashes by reported road surface condition for each study year.
Figure 6 Annual Crashes by Road Surface Condition
The number of crashes on winter weather road surfaces has decreased from over 70 crashes per year in
2010 and 2011 to fewer than 30 crashes per year in 2013 and 2014. The number of crashes occurring

on a dry roadway surface is more consistent. This number varies from a low of 28 crashes in 2010 to a
high of 39 crashes in 2012.
The variation in winter weather road surface crashes could
potentially be the result of changes in ITD snow and ice
removal practices implemented around 2012, yearly variations
in weather patterns, and/or a combination of the two (or other
unknown) factors. ITD provided data from the four road
weather information system (RWIS) stations it maintains along
the corridor: Fall River, Sheep Falls, Osborne Bridge, and
Henrys Lake. These stations record information regarding
weather and road surface conditions, including weather there
is snow or ice present on the road and the grip level of the
roadway.
Only one station, Henrys Lake, has data regarding the condition of the road surface before 2012. The
first complete year of road surface data at this station is 2011. Figure 7 summarizes the percentage of
time that this RWIS station reported ice or snow on the road surface or a grip level of less than 0.6,
which is ITD’s threshold for whether a road is considered slick. Given that this data sample is limited to
only four of five years and one of four stations along a corridor that is longer than 50 miles, it is difficult
to draw any conclusions from this data. It is presented here for information only.
Figure 7 Ice/Snow Conditions at Henrys Lake RWIS Station (2011 - 2014)
US 20, near Henrys Lake, had a grip level of less than 0.6 about 12-13% of the time during 2013 and
2014, compared to about 15-17% during 2011 and 2012. Winter weather related crashes were lowest in
2013 and 2014 when this station reported the lowest proportion of ice or snow covered roads.
However, winter weather related crashes were lower in 2012 than 2011, even though this particular
station reported ice or snow covered roadways a greater percentage of the time in 2012 than 2011.

ITD should consider additional analyses at other locations throughout the state to better understand
the impacts its maintenance practices may be having on crashes during the winter.
Crash Type
Figure 8 summarizes crashes by type.
Figure 8 Crashes by Type (2010 – 2014)
Overturn crashes are the most common reported crash type, with about 30% of all crashes being
classified as such. These crashes may or may not involve a vehicle leaving the roadway. According to the
crash data, about 90% of the overturn crashes involved someone leaving the roadway. Combined with
fixed object and other off-roadway crashes, these single-vehicle roadway departure crashes make up
nearly half of all crashes on the roadway and are a point of emphasis in ITD’s 2013 Strategic Highway
Safety Plan (SHSP, Reference 8).
Other key findings from a review of this data include:
Animal crashes make up nearly 20% of the reported crashes
along the corridor (i.e., 81 crashes).
The other types of lane-departure crashes, side-swipe and
head-on crashes, account for just over 10% of reported
crashes (i.e., 48 crashes).
Crashes that are likely related to intersections or other
accesses (i.e., angle, turning, and rear-end crashes) represent about 8% of reported crashes
(i.e., 35 crashes).
Most (i.e., 27 out of 49) “other” crashes were reported as jackknife crashes.

o The majority, (i.e., 24 out of 27), of the jackknife crashes occurred on reported ice,
snow, or slush covered roadways
Weather may be a contributing factor to the overturn crashes, as nearly all (i.e., 129 out of
131 crashes) are reported to have occurred on ice, snow, or slush covered roadways.
o Fixed object and other roadway departure crashes still make up approximately one-
third of all crashes on dry and wet roadways.
Intersection Crash Trends
Of the crashes on US 20, approximately 8 percent were located at intersections and other driveways.
This doesn’t include the crashes on the side streets. In order to evaluate the crash characteristics at
intersections along the corridor, crash data was obtained and reviewed for the following intersections
of US 20:
State Highway (SH) 87
Sawtelle Peak Road – Big Springs Loop Road
Big Springs Loop Road (southern intersection)
Yale-Kilgore Road
Mesa Falls Scenic Byway
SH 47
The number and severity of reported crashes at each intersection is summarized in Figure 9.

difficult to discern any patterns at individual intersections. All of the crashes at the three most northern

intersections (i.e., SH 87, Sawtelle Peak Road, Big Springs Loop Road) are reported to have occurred on
ice or snow-covered roads. The crashes at Yale-Kilgore Road and SH 47 are reported to have occurred
on dry roads. No crashes were reported at the Mesa Falls Scenic Byway intersection.
There was one fatal crash at SH 47 when an individual riding a motorcycle was struck by a person
driving a car and thrown from his vehicle. According to the report, he was not wearing a helmet.
Relative Highway Safety Performance
The following section takes a closer look at the crash data by examining where on the corridor crashes
are occurring. For the purposes of this analysis, the corridor has been divided into 49 relatively
homogenous segments of varying lengths to allow for analysis according to the Highway Safety
Manual’s predictive method for rural two-lane, two-way roadways.
Three measures are first examined to review the safety performance of the US 20 corridor:
Observed Crash Rate – This is the number of reported crashes per 100 million vehicle miles
traveled on each segment.
Expected Crash Rate – This rate is calculated using the Highway Safety Manual’s predictive
method and represents the crash rate expected to occur based on the geometric and traffic
characteristics of the roadway. It is calculated using national models calibrated to Idaho
data (Reference 9) and the observed crash data. This rate accounts for the random variation
that tends to occur in crashes, providing a more reliable estimate of the safety performance
of a segment.
Highway Safety Corridor Analysis (HSCA) Score – The HSCA score provides greater weight to
fatal and serious injury crashes than the above measures. It is calculated by ITD for the
entire State highway system and the resulting scores are a relative measure of how each
segment is performing compared to the remainder of the statewide system. The scores
used in this analysis are taken from IPLAN for the year 2014.
Figure 10 shows the performance of the US 20 corridor with respect to each of these measures. For the
purposes of this analysis, the crash rate measures are shown in three categories with an equal number
of segments in each category (i.e., a relative high/medium/low categorization). The HSCA scores are
shown according to their ITD classification (i.e., they are relative to the statewide system and not just
the US 20 corridor).
Generally, the three measures are in approximate agreement with respect to the relative performance
of each segment. There are some variations between the two crash rate measures as to the relative
performance of certain segments; however these are differences of one category (e.g., a “red” segment
in one measure may show up as “yellow” in another, but no red segments show up as “green” in the
other). The segments shown in red in the expected crash rate portion of the figure are where we would
expect the greatest potential for return on geometric related safety improvements.

Most of the corridor falls into the “medium” tier for its HSCA score. The two exceptions are the section
through Ashton, which falls into the “high” tier, and the southern end of the corridor south of milepost
357, which falls into the “low” tier.
Observed vs. Expected Crash Rates
The observed and calculated expected crash rates vary by differing amounts, as shown in Figure 11.
Differences in the two rates are most likely due to one of the following reasons:
Temporal variations in the observed crash rate – Crashes are random events and where they
occur varies from one year to another. As a result, the observed crash rate for any given site
is likely to be different depending on the years of crash data included. This can especially be
an issue on a rural highway, such as US 20, with lower traffic volumes where slight changes
in the number of reported crashes can result in large changes in the crash rate. The
calculated expected crash rate overcomes this fluctuation in data by estimating the long-
term average crash rate.
Factors not fully captured in the HSM models influencing crashes – The HSM model used for
this study is based on data from several states and has been calibrated to Idaho statewide
conditions. However, there are still localized conditions that could be resulting in variations
from the expected crash rate. For the US 20 corridor, two factors that may be resulting in
more crashes than expected include:
o Winter weather crashes – As previously noted, over half of the reported crashes
took place on winter weather road surfaces. While the model has been calibrated to
Idaho conditions, this was a statewide calibration effort, including highways in the
drier and warmer parts of the state.
o Animal crashes – Animals were involved in about 20% of all crashes along the
corridor and about 24% of all single-vehicle crashes. This is nearly twice as high as
would be expected based on the HSM data (about 12% of all crashes are animal
related) or Idaho statewide data (about 13% of single-vehicle crashes are animal
related, Reference 6).

Figure 11 Expected vs. Observed Crash Rate
Crash Location by Type/Contributing Factor
Figure 12, Figure 13, and Figure 14 map out the density of crashes by type or contributing factor. The
figures show a relative density range, with an equal number of roadway segments in each of the three
categories (i.e., green segments represent the lowest third of densities, yellow segments represent the
middle third, and red segments are the most dense third of segments). The observed crash frequency is
included in these figures for comparison purposes.
The crash types and contributing factors that are mapped out are:
Winter weather road surface conditions
Animal crashes
Roadway departure crashes
Sideswipe/head-on crashes
Angle, turning, and rear-end crashes (i.e., crashes potentially related to accesses)
Notable findings from this preliminary analysis include:
There is some consistency between the locations with the greatest density of winter
weather road surface crashes and the highest expected crash rates indicating that winter
weather may be exacerbating existing roadway conditions that make these areas more
likely to have crashes than other areas on the corridor.
Roadway departure crashes are generally higher in areas with higher expected crash rates,
which may indicate geometric conditions, such as narrow shoulders or curves are the
primary contributing factor(s) to roadway departure crashes, in addition to weather.

US 20: Chester to Montana Safety Corridor Plan November 2016 Safety and Operations Analysis
27 Kittelson & Associates, Inc.
Locations with a higher density of head-on and side swipe crashes are sometimes consistent
with the areas with a higher expected crash rate, but not to the same extent that roadway
departure crashes are.
Access density and the density of angle, turning, and rear end crash types are generally
correlated throughout the corridor, but not in all cases. This could be due to other access
related factors, in addition to density (e.g., volumes, spacing, sight distance).
Comparison to 2006 Study
The results described above were compared to the findings from the 2006 corridor study. This study
recommended access management, passing lanes, turn lanes, wildlife crossing studies/mitigation, and
widened shoulders, in addition to specific intersection projects. These recommendations are generally
consistent with the findings described above.
There are some notable differences between the crash data reviewed for this analysis and the crash
data included in the previous study:
Potential intersection and access related crashes (i.e., rear-end, turning, and angle crashes)
made up 25% of the crashes reviewed for the 2006 study, while they only make up about
8% of the crashes from 2010 to 2014.
Conversely, fixed object, overturn, and other loss of control type crashes made about 37%
of all crashes in the 2006 study, while they account for approximately 57% of all crashes
from 2010 to 2014.
The proportion of head-on and sideswipe crashes has also decreased from about 17% of all
crashes to 11% of all crashes.
The difference in the proportion of crash types could be due to random variations in crashes in general,
weather, projects implemented since the 2006 corridor study, changes in how crashes are reported,
other factors not listed here, or some combination of all of these factors.
SUMMARY
The following summarizes key observations regarding safety and operations on the US 20 corridor:
The crash analysis found relatively consistent trends with respect to the observed crash
rate, expected crash rate, and HSCA score.
Weather is a significant contributing factor to crashes on the corridor, with over half of all
crashes reportedly occurring on ice, snow, or slush covered roadway.
Roadway departure crashes are the most common crashes on the corridor, indicating a
potential to reduce crashes through countermeasures that lower the chance vehicles will
leave the roadway.
US 20: Chester to Montana Safety Corridor Plan November 2016 Safety and Operations Analysis
28 Kittelson & Associates, Inc.
The LOS is expected to be “D” or worse by the year 2036 on most of the corridor during the
peak summer period.
These findings are generally similar to the previous 2006 study; although the percentage of
crashes occurring at intersections has decreased while the percentage of overturn and fixed
object crashes have increased.
Section 4 Project Alternatives

PROJECT ALTERNATIVES
Based on the analysis presented in the preceding section, several different potential countermeasures
that to cost-effectively reduce crashes and/or improve traffic operations were identified and reviewed.
This section summarizes the treatments considered and the results of an analysis of their effectiveness.
PROJECT ALTERNATIVES CONSIDERED
The improvement alternatives considered treatments to add capacity and countermeasures to reduce
crashes. Sources of potential countermeasures include the Federal Highway Administration’s Proven
Safety Countermeasures (Reference 10), ITD’s SHSP, the Highway Safety Manual, and our experience
from previous safety and operations related work. We have identified the following improvements and
countermeasures that could potentially be deployed along the corridor systematically or at select
locations:
Capacity and Safety
Improvements/Countermeasures
o 2 + 1 Configuration (i.e.,
alternating passing lanes)
o Wider shoulders
o Access management
Safety Countermeasures
o Edgeline rumble strips
o Centerline rumble strips
o Safety Edge
o Enhancing clear zones
Each of the treatments listed above was evaluated with respect to its expected effectiveness at
reducing crashes along the corridor. The addition of passing lanes was also reviewed from an
operations perspective. This analysis is described in the following sections.
2 + 1 Configuration
Providing passing lanes in alternating directions
along two-lane highways can be a cost-effective
means to reduce crashes and improve traffic
operations without incurring the expense of
constructing a complete four-lane facility. This
pattern of alternating passing lanes is often
referred to as a “2 + 1” configuration, or, in Texas,
a “Super 2” configuration (Reference 11). Figure
15 provides a conceptual illustration of the 2+1
configuration. Today, travelers on US 20
infrequently encounter passing lanes. As
previously discussed, this is expected to contribute
to increased delay along the corridor as traffic
volumes grow. With the 2+1 configuration, passing

31 Kittelson & Associates, Inc.
lanes are provided in alternating directions as frequently as practical along the corridor.
Figure 15 Conceptual Illustration of 2+1 Concept Compared to Existing Conditions
Currently, one section of alternating passing lanes exists on US 20 from approximately milepost 390 to
392, where there is a northbound passing lane from about milepost 390 to milepost 391 and then a
southbound passing lane from about milepost 391 to milepost 392.
Figure 16 illustrates a potential configuration for how a 2+1 configuration might look on US 20. The
concept, as shown, includes about 26 new miles of passing lanes, which is about half the length of the
corridor. To develop this concept, passing lanes are proposed to be added to the existing 2-lane
sections using the following criteria:
Generally, the passing lanes are alternated from one side to the other side every mile
(including transition, so the lanes will be a bit shorter than a mile each).
o This length is based on reviewing previous research on the 2+1 concept in the US
and Europe, and best practices for passing lane design (References 11-14).
Exceptions to the mile spacing occur as follows:
o Transitions are avoided on curves
o The third lane will be a turn lane at major intersections where there is not already a
turn lane
o A third lane is maintained on the uphill side of any grade of 3% or greater
Further engineering analysis would be needed to determine the exact location and lengths of each new
passing lane.
Figure 17 shows the expected reduction in crashes as a result of implementing this proposed
configuration. Based on research summarized in the HSM, the 2+1 configuration is expected to reduce
crashes by approximately 25% wherever new passing lanes are added, which is shown on the figure as
about half of the corridor.
Another benefit of providing regular passing opportunities is improved traffic flow. Figure 18 and Figure
19 show how traffic operations would be improved by implementing the 2+1 concept under both
existing and projected year 2036 conditions. Notably, the level-of-service (LOS) in the year 2036 can be

expected to be “C” or better along much of the corridor, with a few sections of LOS “D,” and one
segment of LOS “E,” which is not affected by the 2+1 configuration. Whereas, without the additional
passing lanes, the LOS is expected to be “D” or “E” along most of the corridor by 2036.
Wider Shoulders
Wider shoulders have been proven to reduce crashes
on rural two-lane highways. This effect has been
quantified for shoulders up to 8 feet in width in the
Highway Safety Manual. Shoulder widths on the
corridor currently vary from 0 feet to 8 feet.
Figure 20 summarizes where shoulders on US 20 could
potentially be widened to 8 feet and what the
expected change in crashes would be if this were to
occur.
Nearly 40 miles of the corridor could benefit from
shoulders being widened to 8 feet. The expected crash
reduction benefit of widening shoulders depends on
the current width of the existing shoulders. On the US 20 corridor, based on the crash modification
factors in the HSM, the expected safety benefit of 8-feet wide shoulders ranges from approximately
13% to 33%, with the greater benefit expected where existing shoulders are the most narrow.
ITD’s current standard shoulder width is 6 feet (Reference 5). Widening shoulders that are narrower
than this standard to 6 feet would also have a benefit, though it would not be as great as widening to 8
feet. A comparison of widening shoulders to 6 feet versus 8 feet is included in Appendix “D.”

Edgeline Rumble Strips
Rumble strips are one of FHWA’s Proven Safety
Countermeasures that the agency is encouraging
jurisdictions to implement. While implementing edgeline
rumble strips on a systematic basis can be a cost-effective
means to reduce run-off-the-road crashes, there are
considerations that need to be accounted for:
Proximity to residences and lodging – The noise
created by a vehicle running over a rumble strip
can be heard from a distance and may disturb
surrounding residents. Our understanding is that ITD’s current guidance is to not install
rumble strips on highways when they travel through areas with residential uses.
Impacts to people bicycling – Rumble strips can also create a nuisance for people bicycling
on the shoulder. Providing wide shoulders (i.e., 6’-8’ wide) anywhere rumble strips are
installed can help avoid these conflicts.
Minimum shoulder width – ITD’s standard drawings (Reference 15) note that rumble strips
should be installed only when the width of the shoulder is 4’ or greater. For shoulder widths
of at least 2’, but less than 4’, rumble stripes, which are only 6” wide and include the
edgeline striping, may be installed.
Figure 21 illustrates candidate locations for edgeline rumble strips, taking into account the above
considerations, as well as the expected crash reduction benefit of providing them at these locations.
There are currently about 9 miles of edgeline rumble strips on US 20 and the figure includes
approximately 28 additional miles of rumble strips.
The expected crash reduction benefit of edgeline rumble strips is calculated using the crash
modification factor (CMF) contained in NCHRP Report 641 Guidance for the Design and Application of
Shoulder and Centerline Rumble Strips (Reference 16). This CMF calculates a reduction in single vehicle
run-off-the-road crashes, based on the observed frequency of these crashes, or if there is no observed
history, the expected proportion based on data contained in the HSM. Based on these calculations, the
expected safety benefit of edgeline rumble strips is a reduction in crashes of about 3% to 15% wherever
they are installed.

Centerline Rumble Strips
Centerline rumble strips are deployed primarily to reduce crossover
type crashes, such as head-on collisions and run-off-the-road left
crashes. Similar to edgeline rumble strips, the potential noise impacts
on surrounding development should be considered before selecting a
location to install them. ITD also recommends that centerline rumble
strips should not be installed when the combined lane and shoulder
width is less than 12’ or where two-way left-turn lanes are present
(Reference 5). Figure 22 illustrates potential candidate locations along
the corridor for centerline rumble strips, taking into account these
considerations. It includes approximately 46 miles of potential center
rumble strips. The figure also summarizes the expected crash
reduction benefit of providing them at these locations, which is about a
9% reduction in all crashes based on the CMF in NCHRP Report 461
(Reference 16).
Enhancing Clear Zones
Removing trees and other fixed objects from the roadside can
provide additional clear zones for vehicles that leave the
roadway. Removing roadside trees also has the additional
benefits of providing for more sunlight on the roadway during
winter, which can result in faster snow/ice melt, and providing
a greater viewing area for seeing wild animals that may enter
the roadway. Figure 23 shows the locations along the US 20
corridor where the immediate clear zones could potentially be
improved and the expected crash reduction benefit of
improving them, based on the expected decrease in the
roadside hazard rating described in the Highway Safety
Manual.
Access Management
Access points introduce turning movement conflicts to the highway. Reducing the number of accesses
and/or restricting certain movements at specific locations can reduce access-related crashes. Any type
of potential access modification needs to be considered within the context of how it may affect
adjacent development served by the access and the implications of focusing more traffic at other
intersections and driveways. The 2006 corridor study recommended access modifications in a few
specific locations. Figure 24 illustrates these locations and the expected crash reduction benefit
associated with those access modifications.

Other Considerations
Other treatments that were considered as part of this study or by one of the ongoing projects
previously referenced include:
Safety Edge
Roadside tree clearing
Animal crash reduction strategies
These treatments are discussed below.
Safety Edge
Safety Edge is a tool that is used when paving the edge of a roadway. It provides an approximately 30-
degree tapered angle at the end of the road and helps reduce run-off-the-road crashes. Safety Edge is
also one of FHWA’s Proven Safety Countermeasures. This treatment could potentially be applied to
most sections of US 20 without guardrail. The expected reduction in crashes wherever this treatment is
installed is about 6% (Reference 17).
Roadside Tree Clearing
The benefits of removing trees immediately adjacent to the road to provide adequate clear zones were
previously discussed in the Enhancing Clear Zones section above. However, there may also be benefits
to removing trees further out from the highway in order to provide:
More sun on the roadway during the winter to aid in snow and ice melting
Greater viewing area of wildlife approaching the road
For the above reasons, ITD previously removed all trees within approximately 100’ of the centerline of
US 20 from approximately milepost 369 to milepost 377. According to a solar model run by ITD staff,
this tree removal project should have provided up to 4 hours of additional direct sunlight in the winter.
Figure 25 illustrates other locations that may be candidates for similar treatment. These locations were
identified based on a survey of existing tree stands within 100’ of the highway using aerial imagery. Not
all of these locations were previously identified for enhanced clear zones because the trees may be
located on hillsides adjacent to US 20 and/or behind guardrail in several locations. Additional modeling
would need to be conducted to identify how much additional sunlight could be gained at these
locations. ITD has already completed this analysis for Targhee Pass (i.e., approximately milepost 402 to
milepost 406).
Priority areas for further analysis would include those areas where both winter weather and animal
crashes are highest, as also shown on Figure 25 (i.e., mileposts 393 to 394, 386 to 384, and 366 to 367).

Animal Crash Reduction Strategies
The ongoing ITD District 6 Wildlife Study is developing recommendations for treatments along seven
different segments of US 20. Expected benefits of the treatments are also being calculated as part of
this project. Draft recommendations from this project include a number of strategies, including wildlife
under/over-passes, wildlife fencing, warning systems, lower speed limits, and sight distance
improvements.
Section 5 Recommendations
US 20: Chester to Montana Safety Corridor Plan November 2016 Recommendations
48 Kittelson & Associates, Inc.
RECOMMENDATIONS
This section provides a comparison of the project alternatives reviewed in the previous section and
summarizes the recommended long-term configuration of this section of US 20 and the expected
benefits of this configuration.
COMPARATIVE SUMMARY OF ALTERNATIVE TREATMENTS
Figure 26 provides a summary of the overall expected change in crashes with each of the proposed
treatments and Figure 27 and Figure 28 summarize the expected change in the crashes resulting from
each of the proposed treatments along the corridor.
Figure 26 Crash Frequency on US 20 Corridor with Potential Treatments
Both the calculated expected crash frequency and the observed crash frequency from the crash data
reviewed for this study are shown in Figure 26. As was noted before, the expected crash frequency
provides, in theory, a more reliable estimate of the long-term average crash frequency. At the same
time, there may be factors on this corridor that are influencing crashes that are not accounted for in the
HSM’s models (e.g., weather, animal migration patterns). Therefore estimates based on both measures
are included in order to show the likely range of crash frequencies with each treatment.
As shown in the figures, the 2+1 configuration and widening shoulders to a uniform 8’ width are
expected to provide the greatest reductions in crashes. Further, the 2+1 configuration is expected to
provide for long-term traffic operations, without the expense of constructing a four-lane highway, as
was previously shown in Figure 19.

US 20: Chester to Montana Safety Corridor Plan November 2016 Recommendations
51 Kittelson & Associates, Inc.
RECOMMENDED LONG-TERM CONFIGURATION OF US 20
Given the above findings, our recommendation is that the 2+1 configuration with 8’ shoulders should
be adopted as the long-term vision for the US 20 corridor between Chester and the Montana State line.
Additionally, other less significant treatments, such as the other alternatives evaluated here (i.e.,
rumble strips, Safety Edge, enhancing clear zones, and access management), should still also be
considered in a case-by-case basis as the roadway is reconstructed. These treatments can often be
implemented at a low-cost as part of another project and are not dependent on the ultimate
configuration of the highway being built.
Figure 30 illustrates where passing lanes could potentially be added and shoulders widened to 8’ along
the US 20 corridor, as noted in the previous section. Appendix “E” contains example photos of areas
recommended treatment.
Expected Benefits of Recommended Configuration
The recommended configuration provides both safety and operational benefits, which are described in
the following sections.
Safety Benefits
Figure 30 also summarizes the expected reduction in crashes along the corridor, while Figure 29
summarizes the expected safety performance of the recommended configuration compared to existing
conditions for all crashes, as well as crashes by severity. This summary is provided based on applying
the CMFs for the treatments to both the calculated expected crash frequency and the observed from
historical data crash frequency.
Figure 29 Safety Performance by Crash Severity - Existing vs. Recommended Configuration
In total, the recommended configuration is expected to reduce all crashes on the corridor by 25-30%,
fatal/injury crashes by about 20-25%, and property damage only (PDO) crashes by 25-30%. This results
in an economic benefit of approximately $700,000 to $1,350,000 per year in crash cost savings, or $14

million to $27 million over a 20-year design life, depending on whether the expected or observed crash
frequency is used as the basis.
Operational Benefits
Providing frequent and regular passing opportunities will improve traffic flow on the corridor by
reducing the amount of time people spend following slower vehicles. Figure 18 and Figure 19 previously
summarized the expected level-of-service of the corridor with the 2+1 configuration under existing and
projected year 2036 conditions. Figure 31 summarizes the overall operational performance of the
recommended configuration compared to the existing conditions.
Figure 31 Operational Performance - Existing vs. Recommended Configuration
As previously noted, the 2+1 configuration is expected to provide for a LOS of “C” or better along much
of the corridor in the year 2036. It is also expected to reduce the percentage of time that people spend
following from an average of 73% in the year 2036 to 63%, during peak conditions in the peak direction.
The percent time spent following will be lower in the off-peak direction and during most of the year.
Next Steps
The recommended configuration requires widening the existing highway as little as 2 feet (i.e.,
widening the shoulder from 6 to 8 feet) and by as much as 16 feet (i.e., adding a 12-foot passing lane
and widening the shoulder by 4 feet). An engineering evaluation of the level of effort that would be
required to perform this widening was not completed for this study. Further engineering analysis will be
needed to determine the exact location and lengths of each new passing lane, as well as the level of
effort that will be required to widen the highway to accommodate the additional passing lanes and
shoulder widths. This subsequent analysis should estimate the costs of implementing the concept so
that a benefit-cost ratio can be calculated to verify the cost-effectiveness of the proposed projects.
