AN OVERVIEW OF KEY FINDINGS
The results from the 2017 I‐70 User Study Research Program are presented in the attached report.
This overview presents a summary of key findings from the study that are further documented in
the full report that follows. The full report provides a discussion of research results portrayed
using a series of graphs and charts. Further, notable comparisons to results from past studies are
highlighted.
The 2017 research was designed to allow comparisons to past research. Surveys were conducted
at the T‐Rex and Wooly Mammoth lots on dates in late January and early to mid‐February,
approximately the same weekends that were surveyed in 2014. Additionally, vehicle counters
were place at the Wooly Mammoth lot to measure traffic patterns across several weeks on a real‐
time basis which permits precise analysis of vehicles entering and exiting the lot by time of day.
The research also incorporates survey results from the RRC Front Range Snowsports Enthusiasts
Panel. The data provide input from a broad sample of Front Range winter visitors to mountain
resorts, and it included survey questions that allow comparisons to results from the 2014 Panel.
Notable findings from the intercept survey of T‐Rex and Wooly Mammoth lot users include:
The Dinosaur Lot users profile is predominantly male and young adult. The largest share of lot
users comes from the Denver ZIP Codes (31%), but Jefferson (23%), Boulder (12%) and
Arapahoe (11%) Counties are also strongly represented.
Overall, vehicle occupancy results are similar to prior years of the survey but data suggest
increased use of carpooling. The 2017 results point to a smaller share of drivers arriving at the
lot alone than in 2014 (56% in 2017 vs. 70% in 2014). This suggests that I‐70 travelers may be
starting the carpooling process even before getting to the lots.
Respondents cited an average of 3.0 different motivations for carpooling, highlighting that
there are multiple reasons why carpooling appeals to lot users. As in 2014 and 2012, the most
frequently identified motivation for carpooling was to “save on gas” (73%). Social/fun (55%),
reduce environmental impact (49%), and reduce traffic congestion (46%) were also of high
importance. The desire to reduce environmental impacts, reduce congestion, as well as saving
on resort parking all showed increases over 2014 results.
Respondents estimated using the Dinosaur Lots for roughly half of their winter mountain trips
(an average of 58% and a median of 50%). Meanwhile, just over a quarter of respondents use
the Dinosaur Lots for every single one of their trips to the mountains (27%). Respondents
estimated taking an average of 17.8 trips to the mountains this winter, up from 15.7 in 2014.

Trip destinations are relatively spread out, with no one location attracting a majority of
respondents. Winter Park and Keystone were most cited (18% each), followed closely by
Copper Mountain (14%), Vail (13%), Arapahoe Basin (10%), and Breckenridge (9%).
Results indicate an increased propensity for overnight trips among Dinosaur Lot users. Two in
five respondents (39%) did not plan to return to the parking lot on the day they were surveyed,
up notably from 2014 (24%). Lot users staying in the mountains overnight planned to stay a
median of two nights. As might be expected, lot users arriving Friday stay in the mountains
longer, on average, than those who arrive on Saturdays or Sundays.
Nearly two‐thirds of lot users (64%) indicated that they use I‐70 traffic information sources.
However, certain groups were more likely to use traffic information sources than others. For
one, visitors to Steamboat, Vail, and Beaver Creek are more likely to use information sources
than visitors to other destinations, suggesting that those who are going to more distant
destinations are more likely to engage in trip planning behaviors. Additionally, respondents
who have made 21 or more trips to the mountains are about twice as likely to use traffic
information sources as those who have made five or fewer trips.
Sources of information used by parking lot users. Among users of I‐70 information sources, 51%
indicated they use CoTrip.org, 48% use the CDOT mobile app, and 28% use GoI70.com, with
progressively smaller shares of respondents using other sources. This year, notably more respondents
indicated using CoTrip.org and GoI70.com than in 2014.
Commercial bus and van service was up at the T‐Rex/Wooly Mammoth lots over 2014. While a
small part of overall use, these modes saw increases.
Later returns to the lots were evident in 2017. While planned time of return overall is similar to
2014, lot users were more likely to return later in the evening in 2017. A notably higher share
of respondents planned to return after 7:00 PM (21% in 2017 vs. 11% in 2014), an indication
that some of the efforts to encourage later stays may be yielding positive results. The
percentage of day visitors planning to return after 3:00 PM was 83%, identical to 2014.
Just under one‐third of respondents have ever used the I‐70 Mountain Express Lane (MEXL)
(30%). Those that use it did so an average of 5.0 times. This is generally consistent, albeit
slighter higher than reported usage among respondents to the Front Range Snowsports
Enthusiasts Panel, 25% of whom have ever used the MEXL with an average usage of 2.4 times.

Traffic counts taken by RRC at the lots, as well as CDOT traffic counts at the Eisenhower Tunnel,
produced the following insights:
While the T‐Rex lot was observed to almost always be near or above its reported capacity, the
Wooly Mammoth lot had more variation but heavy use overall, and increases over 2014. The
Wooly Mammoth was at 100% of capacity on a Saturday morning and showed higher levels of
use throughout the study days than was observed in the past. Comparisons by day of week
and time‐periods indicate a consistent overall increase in the number of parked. Most notably,
the number of parked vehicles increased notably during the Friday 2:00‐4:00 PM time frame.
Traffic counters placed at the Wooly Mammoth entrances and exits reveal a consistent fill
pattern by day of week and hour of day. Saturday and Sunday inbound traffic both peak in the
6:00 AM hour, with Saturday having a larger overall volume of vehicles. On Saturdays,
outbound traffic peaks in the 2:00 PM hour, while on Sundays the outbound traffic volume is
slightly more spread out.
Traffic counters reveal a 6:15 – 6:30 AM outbound traffic peak from the Wooly Mammoth lot.
This is consistent with what CDOT’s traffic counters revealed in 2014; however, the peak is
even more pronounced and consistent in 2017.
CDOT Eisenhower Tunnel traffic counts and RRC Wooly Mammoth traffic counts align closely.
Morning westbound traffic peaks at the Eisenhower Tunnel are preceded by peaks at Wooly
Mammoth. However, the peaks are offset, typically by an hour or more. In the afternoon,
following an eastbound peak at the tunnel, Wooly Mammoth traffic spikes again.
The Front Range Snowsports Enthusiasts Panel generated even more insights around behaviors
and perceptions as they relate to I‐70 corridor travel:
A notable 69 percent of panel respondents reported that the frequency of their
skiing/snowboarding had been reduced because of I‐70 congestion. When asked to elaborate
on the specific ways in which their snowsports activity had been reduced, comments centered
around several major themes: avoidance of skiing/riding altogether, skiing/riding at locations
other than those along the I‐70 corridor, skiing/riding during the week instead of on the
weekends, skiing/riding fewer days, and taking overnight trips instead of day trips.
A vast majority of respondents make an effort to avoid the high congestion times on I‐70 (94
percent), up from 90 percent in 2014, and identical to 2012.
On average, panel respondents use a combination of three different strategies to avoid
congestion on I‐70. In 2017, the most common types of strategies involved avoiding weekend
travel (whether it be on Saturday or Sunday specifically, or weekends altogether). The next
most common strategy involved trying to beat peak travel periods by arriving or leaving early
or late.

Respondents who own a pass or lift ticket pack behave differently than those without one. As
was the case in 2012 and 2014, product holders are much more likely to arrive early and leave
early, most likely because pass ownership enables one to enjoy just a few hours of skiing or
riding, whereas those who pay for a full day lift ticket ski/ride longer to get more value out of
their trip to the resort.
Just over one‐third of respondents (36 %) think the new I‐70 MEXL has made a difference in
congestion during peak times. When asked if signage and other information pertaining to the
travel lane is adequate and easily understood, about two‐thirds (67%) said it was.
The major obstacles to using the I‐70 MEXL include cost, perceived danger, doesn’t seem to
save time, and not being open. These were the major themes that emerged in the survey
when the 75% of panel respondents who have not used the MEXL were asked “What keeps
you from using the lane?”
One‐third of panel respondents have used the Dinosaur Lots for carpooling. When asked to
comment on their experience, they were generally quite positive, noting the convenience and
ease of the lots for carpooling. However, some critiques around safety did appear in the
comments as well.

INTRODUCTION AND METHODOLOGY
During mid‐winter 2017, the I‐70 Coalition commissioned a study to investigate parking patterns at
the three Dinosaur parking lots in Morrison, CO. The study follows up on studies conducted during
mid‐winter 2012 and 2014, respectively, and seeks to obtain a greater understanding of lot usage,
carpooling patterns, and related traffic issues. The data collected provide a variety of insights
regarding carpooling patterns and I‐70 user behavior. Study dates and methodology were
designed to closely mirror the 2012 and 2014 studies in order to identify changes and potential
trends over time.

The research involved three primary sources of data collection:
1. On‐site intercept surveys, conducted with a random sampling of lot users to understand
carpooling motivations and behaviors. Surveyors interviewed users of the two lots (Wooly
Mammoth and T‐Rex) over three weekends (six total mornings) in late January and
February. In addition, surveys were collected on two Friday afternoons. A total of 519
interviews were completed, which has a percent confidence interval of approximately 4.3
percentage points calculated for questions at 50% response.
2. Traffic counters, placed by RRC at the entrances to the Wooly Mammoth lot for a period of
two weeks and covered two of the three study weekends. The data provide additional
insight regarding use of the lot at different times of the day and days of the week.
3. Online panel survey using the RRC Associates Colorado Snowsports Enthusiasts Panel.
Questions investigated the opinions and behaviors of Front Range skiers and riders as they
relate to I‐70 travel.
Each of these methods of data collection will be discussed in turn throughout the report.
INTERCEPT SURVEY RESULTS
The following discussion provides an overview of the Wooly Mammoth and T‐Rex survey results. It
addresses the following topics:
Demographics of lot users
Carpooling behaviors and motivations
Trip characteristics
Traffic information source awareness and usage
Ski/van bus and MEXL usage
Results from the intercept research are presented in overall summary form and in many cases are
also segmented by year, day of week, and/or travel destination (Keystone, Loveland, Copper
Mountain, etc.), particularly where notable differences exist.

Demographic Profile
Overall, responses indicate that Dinosaur Lot users fit a predominantly male, young adult profile.
Specifically, males (70%) significantly outnumber females (30%), which is roughly the same
male:female ratio identified in 2014 and 2012. The bulk of respondents are between the ages of
25‐34 (48%), with an average age of 35.9 years. The largest share of lot users comes from the
Denver ZIP Codes (31%), but Jefferson (23%), Boulder (12%) and Arapahoe (11%) Counties are also
strongly represented and in roughly the same proportions as in 2014 and 2012.

Carpooling Behaviors and Motivations
Number of people per vehicle. Results suggest that a typical winter weekend morning at the lots
involves between two and three vehicles meeting, with one departing from the lots while the
remaining vehicle(s) stay parked. On average, there were 1.9 persons per vehicle on trips to the
lots, with more than half of respondents driving alone (56%) or with one other person (23%). In
contrast, there was an average of 2.8 persons per vehicle on trips leaving the lots, with 86% of
vehicles containing two or more people.
Figure 3.
Persons per Vehicle on Trips to the Lots vs. Trips Leaving the Lots
Overall, results are similar to prior years of the survey. However, 2017 results point to a smaller
share of drivers arriving at the lot alone than in 2014 (56% in 2017 vs. 70% in 2014). This suggests
that I‐70 travelers may be starting the carpooling process even before getting to the lots or
traveling to the lots in larger parties.

There were also a few differences depending on where the respondent was traveling to that day,
the number of trips they have taken to the mountains this winter, and prior use of the MEXL:
When evaluated by where the respondent planned on visiting that day, results show that
there are a higher average number of people leaving the lot per vehicle for destinations
that are farther away (e.g., Vail, Beaver Creek, Steamboat).
The average number of people leaving the lot per vehicle is also higher among respondents
who have made more trips to the mountains this winter. This finding may suggest that
more avid mountain travelers have a consistent carpooling group.
Table 1.
People Per Vehicle Leaving the Lot by Number of Mountain Trips This Winter
Respondents who have used the MEXL also have a higher average number of people per
vehicle leaving the lot. Given that cost has been cited as a deterrent to using the MEXL
(see the section on the Front Range Snowsports Enthusiasts Panel later in this report), it
makes sense that those with more people in their vehicle would be more likely to use the
lane (to potentially split that cost).

Motivations for carpooling. As in 2014 and 2012, the most frequently identified motivation for
carpooling was to “save on gas” (73%). Social/fun (55%), reduce environmental impact (49%), and
reduce traffic congestion (46%) were also of high importance. Respondents cited an average of
3.0 different motivations, highlighting that there are multiple reasons why carpooling appeals to
lot users. As compared to 2014, respondents were more likely to cite the desire to reduce
environmental impacts and congestion as reasons for carpooling, as well as saving on resort
parking.
Figure 4.
Carpooling Motivations (Select All That Apply)
While saving on gas is the primary motivation cited among all respondents, there were some
differences in motivations noted when results are assessed by destination. Visitors to
Breckenridge, Copper, and Vail were more likely to cite saving on resort parking as a reason for
carpooling than visitors to other mountain destinations. Meanwhile, visitors to Keystone,
Loveland, Copper, and Winter Park were more likely to cite “social/fun” as a reason for carpooling
than other visitors.

Share of trips using the Dinosaur Lots. Respondents estimated the share of winter trips on which
they use the Dinosaur Lots for carpooling to the mountains. Results show that respondents use
the Dinosaur Lots for roughly half of their trips (an average of 58% and a median of 50%). This is
similar but slightly up from 2014, when respondents estimated that they use the Dinosaur Lots for
an average of 54% of their trips. Meanwhile, just over a quarter of respondents use the Dinosaur
Lots for every single one of their trips to the mountains (27%).
Figure 5.
On approximately what percent of winter trips do you use these Dinosaur Lots to carpool to the mountains?
Use of other carpool locations. One in five respondents (20%) use other Front Locations to carpool
to the mountains. This is down somewhat from 2014 (26%). Among respondents who indicated
using other locations, they use these other locations an average of 44% of the time and a median
of 50% of the time.

Trip Characteristics
The trip characteristics of lot users were probed at the Dinosaur Lots. Respondents were asked to
provide a variety of information about their trip, including vehicle type, destination, and estimated
return time.
Vehicle type. A majority of respondents utilized cars/trucks for their transportation from the lots
(92%). The remaining 8% used commercial vehicles (buses or vans), up notably from 2014 (1%).
Of the three days of the week in which surveying took place, Saturday is the most common day for
commercial vehicle usage—particularly commercial buses. Commercial buses left exclusively from
the Wooly Mammoth Lot, while commercial vans split their departures between the T‐Rex and
Wooly Mammoth lots.

Trip purpose. By far, skiing/snowboarding at a resort was cited as the most common purpose for
the trip (89%), similar to 2014 (85%). While skiing/snowboarding at a resort is still the
predominant use of the lots, others use the lot for other types of recreation trips (8%),
work/business, shopping, and “other” purposes (2% each).
Trip purpose varies slightly by day of the week. For example, a higher share of respondents using
the lots for work/business on Fridays than on Saturday or Sunday. “Other recreation” includes
backcountry skiing, snowshoeing, snowmobiling, and biking, among other activities.

Trip destinations. Trip destinations are relatively spread out, with no single location attracting a
majority of respondents. Winter Park and Keystone were most cited (18% each), followed closely
by Copper Mountain (14%), Vail (13%), Arapahoe Basin (10%), and Breckenridge (9%). Results are
generally similar to 2014, with respondents slightly more likely to go to Keystone, Vail, Arapahoe
Basin, and Steamboat and less likely to go to Breckenridge or “other” destinations in 2017.

Will you return to the parking lot today? Two in five respondents (39%) did not plan to return to
the parking lot on the day they were surveyed, up notably from 2014 (24%). Results indicate an
increased propensity for overnight trips among Dinosaur Lot users.
(If returning today) return time: Day visitors planned to return after 3:00 PM (83%, identical to
2014). While planned time of return is overall similar to 2014, lot users were more likely to return
later in the evening in 2017. A notably higher share of respondents planned to return after 7:00
PM (21% in 2017 vs. 11% in 2014), an indication that some of the efforts to encourage later stays
may be yielding positive results. Conversely, fewer respondents planned to return to the lots
between 5:00 PM and 7:00 PM (31% in 2017 vs. 39% in 2014). These changes are consistent with
results from the Front Range Snowsports Enthusiast Panels findings (discussed later in this report),
which show that respondents are more likely to change their return times to avoid I‐70
congestion.
Interestingly, return times change depending on the day of travel. Saturday and Sunday users are
more likely to return in the early afternoon time frame, between 1 PM and 4 PM.
Figure 7.
Time of Return by Day of Week

(If not returning today) date returning to lot. Overnight visitors planned to return anywhere from
the next day to a week later. Overnight visitors planned to stay a median of two nights in the
mountains. As might be expected, lot users arriving Friday stay in the mountains longer, on
average, than those who arrive on Saturdays or Sundays.
Estimated number of trips to the mountain this season. Overall, results show that Dinosaur Lot
users are frequent mountain travelers. Respondents estimated taking an average of 17.8 trips to
the mountains this winter. This is up from 15.7 in 2014. Results show that 25% of respondents
reported 6‐10 trips, 38% said 11‐20 trips, and 24% said 21‐50 trips.
Traffic Information Source Awareness and Usage
Use of traffic information sources. Overall, 64% of respondents indicated that they use I‐70 traffic
information sources, which is down slightly from the 67% that reported using I‐70 traffic
information sources in 2014, but identical to 2012.
Certain groups were more likely to use traffic information sources than others. For one, visitors to
Steamboat, Vail, and Beaver Creek are more likely to use information sources than visitors to other
destinations. This finding suggest that those who are going to destinations farther away are more
likely to engage in trip planning behaviors than those frequenting the resorts closer to the Denver
metro area.
Respondents who have made more winter trips to the mountains are also more likely to use traffic
information sources. Respondents who have made 21 or more trips to the mountains are about
twice as likely to use traffic information sources as those who have made five or fewer trips. Given
that this is a more active group of skiers/riders, it would make sense they are more engaged in the
available sources of information for traveling the I‐70 corridor.
Respondents who have used the MEXL are also more likely to use traffic information sources. It
stands to reason that these respondents are more likely to take advantage of the MEXL because of
the traffic information they are receiving.

Sources used. Among users of I‐70 information sources, 51% indicated they use CoTrip.org, 48%
use the CDOT mobile app, and 28% use GoI70.com, with progressively smaller shares of
respondents using other sources. This year, notably more respondents indicated using CoTrip.org
and GoI70.com than in 2014. Conversely, they were less likely to report using the CDOT mobile
app or “other” information sources. Interestingly, respondents who have made at least 21 trips to
the mountains are twice as likely as other respondents to use GoI70.com and CDOT email alerts,
suggesting that the most active users of traffic information sources consider these sources the
most helpful.

Likelihood of taking a ski van/bus in the future. Respondents were asked to indicate their
likelihood of taking a ski van/bus in the future. Interest was moderate, with 19% “very likely” to

were very consistent with levels of interest in both 2014 and 2012.
Usage of the eastbound I‐70 MEXL. New to the survey this year, respondents indicated if they
have ever used the MEXL. Thirty percent of respondents indicated they had. Respondents who
have used the MEXL indicated having used it an average of 5.0 times. This is generally consistent,
albeit slightly higher than reported usage among respondents to the Front Range Snowsports

will be informative to use this year’s results as a baseline to understand usage and motivations
around using the lane over time.
VEHICLE COUNTS
Counts of parked vehicles on selected winter dates. In 2017 as in 2014, interviewers conducted
periodic counts of the Wooly Mammoth and T‐Rex lots. At its observed peak in 2014, the Wooly
Mammoth lot reached 96% of capacity on a Saturday at 9:30 AM. On Saturday the 11th at 9:20 it
was full this year. As in 2014, The T‐Rex lot was almost always near or above its reported capacity
of 156 spaces, with exceptions occurring on one Friday evening (February 10th).
Table 6.

Counts of parked vehicles: 2017 vs. 2014. Though 2017 lot counts may not be directly comparable
to 2014, as they were taken on different dates at slightly different times, comparisons by weekday
and time period indicate a consistent overall increase in the number of parked vehicles. Most
notably, Friday lot usage saw the biggest jump since 2014 at both lots. At the Wooly Mammoth
lot, the number of parked vehicles increased 83% in the Friday 2:00‐4:00 PM time frame. At the T‐

Traffic counters: by hour. To provide additional insight into lot usage, traffic counters were placed
at both Wooly Mammoth entrances and exits. The traffic counters reveal a consistent fill pattern
by day of week and hour of day. Figure 10 below shows inbound, outbound, and overall vehicles
by hour of day. As shown, Saturday and Sunday inbound traffic both peak in the 6:00 AM hour,
with Saturday having a larger overall volume of vehicles. On Saturdays, outbound traffic peaks in
the 2:00 PM hour, while on Sundays the outbound traffic volume is slightly more spread out.
Although not the focus of this study, during the week a similar pattern is apparent, but with a
smaller volume of vehicles overall. On all days, inbound traffic is peaking around 6:00 AM, and
vehicles are mostly departing between 2:00 PM to 6:00 PM.

6:15 to 6:25 AM. On the President’s Day Saturday (February 18) the peak was less pronounced but
still evident. Sundays show less volume and slightly more variation in departure time, but the
peak still occurs at the same time.

THE FRONT RANGE SNOWSPORTS ENTHUSIASTS PANEL
Study Background
As a part of the 2017 I‐70 User Study, a series of customized questions was posed to a random
sampling of Front Range skiers/riders via the Front Range Snowsports Enthusiasts Panel. For the
past 16 seasons, RRC Associates has tracked Front Range resident (i.e., individuals residing in one
of the counties listed in the Figure below) generated visitation. This panel is made up of
individuals who have opted to participate in ongoing snowsports‐related research projects
throughout the 2016/17 season. As a part of the 2016/17 season panel survey effort, Front Range
skiers and snowboarders were asked a series of questions about traffic‐related topics on I‐70. This
survey was fielded during the first half of February 2017. Results, which are based on 1,088
completed surveys, were analyzed by age, income, household composition, area of residence
within the Front Range, pass or pack ownership, and year (where available). Segmented results
are shared throughout this section of the report in cases where they had a bearing on response
patterns.

Demographic Profile
Members of the Front Range Snowsports Enthusiasts Panel are generally representative of skiers
and snowboarders in the Front Range as a whole. Sixty percent of panel survey respondents are
male, which resembles the typical 60:40 male to female ratio observed across snowsports. Forty‐
four percent of panel members are from households with children living at home and the average
age of panel members is 38 years. Panel members also mirror the generally higher affluence of
skiers and riders in the Front Range, with 43 percent of respondents reporting annual household
incomes of $75,000‐149,999 and 35 percent reporting an income greater than $150,000. The
demographics of the 2017 panel are very similar to the demographics of the 2014 panel, though
incomes have risen among panel respondents in the last three years.

Panel members are broadly distributed across the Front Range; however, Denver Metro Counties
(Denver, Jefferson, Arapahoe and Douglas) collectively account for roughly half of panel
membership (52 percent). El Paso County (the Colorado Springs area) and Boulder County each
account for about 14 percent of responses. Throughout this section of the report, results are
often segmented by Northern (29 percent), Central (46 percent), or Southern (25 percent) Front
Range residence.

Impact of Congestion on Skiing/Snowboarding
A new question asked respondents if the frequency of their skiing/snowboarding has been
reduced because of I‐70 congestion. A notable 69 percent of all respondents reported “yes,” it
had. Respondents who don’t own a season pass were more likely to be deterred from
skiing/snowboarding (71 percent) than their pass‐holding counterparts (67 percent). Furthermore,
respondents who live in the Central Front Range were more likely to reduce the frequency of their
snowsports activity (76 percent) than those in the Northern (69 percent) or Southern Front Range
(55 percent), presumably because of access to ski areas not located along the I‐70 corridor.

QUALITATIVE INSIGHTS
All comments are provided under separate cover and should be evaluated for the breadth and depth of respondent opinions. However, some key insights garnered from the robust set of open‐ended comments will be presented throughout this section of the report. Respondents were asked, “In what specific ways has the frequency of your skiing/snowboarding been reduced?” Several themes emerged from the comments, including:
Avoid skiing/riding altogether o “Have decided to avoid skiing all together. I ski too few days to justify a lift
pass, the individual day pass prices are outrageous and I REFUSE to sit in heavy traffic to get to a resort.”
o “I had a season pass for 16 straight years. The I‐70 corridor ruined the fun. Plain and simple, I will not drive I‐70!”
o “Avoiding it altogether. Too expensive, too much traffic. Just too much hassle in general.”
Skiing/riding at locations other than those along the I‐70 corridor o “We no longer go to the main Front Range resorts on weekends; we ski
Eldora instead.” o “More time in Steamboat, probably won't go back to Copper because the
tunnel to Georgetown traffic is terrible. Winterpark is a little better” o “I avoid I‐70 altogether. I ski at Crested Butte more than other resorts now
despite it being further away.”
Skiing/riding during the week instead of on the weekends o “I avoid weekends. I even changed jobs partially to ski during week.” o “I try to do more backcountry in non‐I70 areas, like Indian Peaks. If I do
take I70, it’s on a weekday” o “Avoiding the weekends, which is difficult with a typical weekday work
schedule.”
Skiing/riding fewer days o “Fewer trips. Depart earlier and return earlier.” o “Fewer days. Going twice in the same weekend is just too much with all the
traffic. Sundays going home in particular can be rough.” o “Fewer days; Would ski 2‐3 weekends per month if drive were a reliable 2
hours each way.”
Taking overnight trips instead of days trips o “Avoid I‐70 trips unless I have free lodging.” o “Avoiding day trips if we are unable to stay overnight due to busy schedule.
Unpredictable travel time makes it too hard to do a day trip.” o “Fewer days on the mountain and avoiding I‐70 on the weekends. Overnight
trips only.”

Another new question on the 2017 survey asked respondents to indicate if they are taking more
overnight skiing/snowboarding trips because of the I‐70 congestion. Fully, a little more than one‐
third of respondents (37 percent) reported that they were taking more overnight trips. In
particular, season pass holders (42 percent) and couples without children (45 percent) were more
likely to increase their number of overnight trips.

A vast majority of respondents make an effort to avoid the high congestion times on I‐70 (94
percent), up from 90 percent in 2014, and identical to 2012. While the majority of all respondents
make an effort to avoid periods of congestion, there was some variation noted among certain
groups of respondents. Northern Front Range respondents are more willing to accept delays as
part of their trip (11 percent), than those from the Central (5 percent) or Southern (1 percent)
Front Range. Furthermore, respondents who are single and without children are notably more
likely to accept congestion (16 percent) than couples, households with children, or empty nesters
(1 to 3 percent).

Strategies for Congestion Avoidance
Most respondents indicate they use some mix of strategies in order to avoid congestion on I‐70.
On average, respondents use a combination of three different approaches. In 2017, the most
common strategies include arriving early at the resort and leaving early (51 percent), avoiding
skiing/snowboarding on Saturdays (38 percent), and avoiding skiing/snowboarding on Sundays (36
percent). Respondents were more likely to adopt each of these tactics this year as compared to
2014—particularly, the avoidance of weekend skiing/snowboarding. This year, respondents were
notably less likely to stay overnight, check CDOT for real‐time information, or arrive at the resort
later and stay later.
Figure 18. Strategies for Congestion Avoidance by Year
I-70 User Study—Final Results March 2017
RRC Associates 30
Assessed another way, the efforts adopted to avoid I‐70 congestion may be grouped into key
strategies. In 2017, the most common types of strategies involved avoiding weekend travel
(whether it be on Saturday or Sunday specifically, or weekends altogether). The next most
common strategy involved trying to beat peak travel periods by arriving or leaving early or late.
While arriving early and leaving early appears to be the most popular of these strategies, a notable
share of respondents will also arrive early and leave later. Diverting or modifying travel, staying
overnight, and using CDOT real time information are also relatively used approaches, but not as
frequently used as avoiding weekend travel or altering travel times.
Figure 19. Strategies for Congestion Avoidance by Year
I-70 User Study—Final Results March 2017
RRC Associates 31
Strategies also differ when evaluated by Front Range area of residence. While all groups are most
likely to arrive early and leave early, this is a particularly popular strategy among residents of the
Central Front Range (60 percent). Central Front Range residents are also more likely to avoid
skiing/snowboarding on weekend days, stay overnight, and divert to the frontage road system. In
fact, Central Front Range respondents were more likely to select a number of strategies (3.4 on
average), as compared to Northern (2.4) and Southern (2.3) Front Range residents. These results
suggest that Central Front Range residents are particularly impacted by congestion on I‐70.
Respondents who modify their travel patterns to take other roads were asked to identify these
alternate routes: Northern Front Range respondents reported that they will use Highway 6 and
frontage roads; Central Front Range respondents will often take 285 or a combination of 40 and 6;
Southern Front Range respondents will often rely on Highway 24.

Analyzing strategies for congestion avoidance by age provides additional insight into tactics
adopted by key demographic groups. Older respondents are more likely to arrive later and stay
later at the resort and equally likely to avoid weekend travel as their younger counterparts.
Meanwhile, younger respondents are more likely to try each of the other methods more so than
older respondents. They are particularly more likely to arrive early and stay later, arrive early and
leave early, and to stay overnight near the resort.

RRC Associates 33
Respondents who own a pass or pack behave differently than those without one. As was the case
in 2012 and 2014, product holders are much more likely to arrive early and leave early, most likely
because pass ownership enables one to enjoy just a few hours of skiing or riding, whereas though
who pay for a full day lift ticket want to get more value out of their trip to the resort. Ultimately
pack and pass holders were much more likely to adopt each of the strategies for congestion
avoidance.

I-70 User Study—Final Results March 2017
RRC Associates 34
Strategies for congestion avoidance also varied by the income of respondents. As in prior years,
higher income households are more likely to stay overnight, although the use of this strategy is
down by all respondents overall. Lower income respondents are more likely to arrive early and
leave early, arrive early and leave later, arrive later and leave later, and avoid skiing/snowboarding
on Saturdays. Respondents within the $75,000 to $149,999 income category are more likely than
respondents from the other income brackets to avoid skiing/snowboarding on Sundays, avoid
weekend travel, check CDOT, divert to the frontage road, and modify their travel patterns to take
other roads.

I-70 User Study—Final Results March 2017
RRC Associates 35
As might be expected, life stage impacts the strategies used to avoid congestion on I‐70. Singles
are much more likely to arrive early at the resort and stay later. Couples without children (as well
as households with children) are most likely to arrive early and leave early. Couples without
children are also more likely than the other segments to avoid skiing/snowboarding on Saturdays
and Sundays, stay overnight, check CDOT, and use the frontage road. Households with children
are more likely than the other groups to modify their travel patterns. Finally, empty nesters are
least likely to engage in each these strategies, except for being relatively likely to avoid weekend
travel, instead opting to ski/board on the weekdays. Given that there are a higher share of
retirees in this group, this strategy is likely more available to them than to respondents in the
other household categories.
Figure 24. Strategies for Congestion Avoidance by Household Composition
I-70 User Study—Final Results March 2017

Given that respondents will behave differently depending on household composition, it’s worth
taking a closer look at these strategies by household group. In the graph below, couples without
children and empty nesters are grouped together, as they behave most similarly. While all groups
are most likely to arrive early at the resort and leave early, their other top strategies differ slightly.
Singles (28 percent of all respondents) are more likely to arrive early and stay later or stay
overnight. Couples without children (28 percent of all respondents, including couples without kids
or empty nesters) are slightly more likely to avoid skiing on one weekend day. Households with
children comprise 44 percent of the sample, and are much more likely to arrive early and leave
early. They are less likely to employ other strategies, but are slightly more likely to avoid
skiing/snowboarding on a Saturday than a Sunday.

I‐70 MEXL Usage and Perceptions
About one‐quarter of all respondents have ever used the eastbound I‐70 MEXL. These
respondents have used the MEXL 2.4 times, on average. Usage of the MEXL is higher among those
who don’t own a season pass (although season pass holders have used it more times on average –
likely because they have an overall higher frequency of travel on I‐70). Higher income households
and respondents who live in the Southern Front Range are also more likely to have used the MEXL.
Figure 26.

Just over one‐third of respondents (36 percent) think the new lane has made a difference in
congestion during peak times. When asked if signage and other information pertaining to the
travel lane is adequate and easily understood, about two‐thirds (67 percent) said it was.

RRC Associates 39
While only 13 percent of respondents noted that they are more likely to travel I‐70 more
frequently at peak times because of the MEXL, this still represents a large share of I‐70 travelers
overall. It will be important to use these results as a baseline moving forward in order to
understand the ways in which the new express lane impacts I‐70 travel patterns over time.
Furthermore, certain groups indicate they are more likely to travel I‐70 more frequently during
peak times as a result of MEXL. As shown below, respondents who make between $75,000 and
$149,999 per year indicate they are more likely to travel I‐70 more frequently (20 percent), as are
households with children (17 percent) , and those who reside in the Southern Front Range (slightly
more likely).

QUALITATIVE INSIGHTS Respondents who have not used the MEXL were asked, “What keeps you from using the lane?” The major obstacles reported include:
Cost o “It's already expensive to ski and park.”
Not perceived to save much time o “It is overpriced for such a short distance. Essentially it has little impact on
total travel time”
Seems dangerous o “It seems dangerous. There's no shoulder to navigate wrecks or for wrecks
to get off the I‐70.”
Not open o “There were a couple of times I wanted to used it, but it was closed (red X)
due to accidents.” Respondents were asked if they had any other comments on the MEXL. A variety of responses were provided, but there were some recurring themes:
Doesn’t appear to help congestion o “Doesn't seem to have improved travel times.”
Interest in a westbound lane o “Make another one for westbound travelers.”
Interest in the lane being open more often o “Please open it 7 days a week!!! Why did you build it if you weren't going
to have it open???”
Lack of understanding around how the lane works (e.g., cost, when open) o “Don't understand why it's only open at certain times. There have been
times of heavy traffic heading towards Denver and the lane is close. So frustrating!”
Lane should be less expensive, especially for HOVs o “Make it cheaper or free for HOV 3+”
Notice misuse of the lane o “People are consistently going over the solid white lines and no patrol is
there to stop them. We avoid the express lane as we're nervous someone is going to hit us coming over.”
Positive impact on congestion avoidance o “I took it last weekend and felt that it did actually save me some time. I
took it because I had a whole car load of people and moving really helps the mood in the car. If I was by myself I would probably not have spent the $5.”

Dinosaur/Morrison Parking Lots Usage
A notable one‐third of respondents have used the Dinosaur/Morrison parking lots for carpooling
either this season or last season. Respondents who own a season pass or pack are more than
twice as likely to have used the lots as those without a pass or pack. Furthermore, those within
lower income brackets, younger respondents, singles and couples without children, and those who
live in the Northern and Central Front Range are more likely to have used the lots.

QUALITATIVE INSIGHTS Respondents who have used the Dinosaur/Morrison Parking Lots for carpooling were asked, “Do you have any comments on your experience using these lots?” Responses were generally quite positive:
o “Access is very easy and convenient” o “Convenient location. Always plenty of spaces available” o “Love these lots!! Crucial for carpooling.”
However, there were several critiques/suggestions offered:
o “Entry into various lots is confusing the first time, and verifying that you are in the correct section to meet your friends.”
o “Great opportunity. More lighting would be nice, my girlfriend's car got broken into. A porta potty would be good, people just go anywhere in the lot.”
o “Lots of litter and broken glass from car break‐ins.” o “Surprised lot was nearly full Saturday morning at 5:30am”

Carpooling
While there was a small dip in the share of respondents aware of resort carpooling incentives (22
percent in 2017 vs. 26 percent in 2014), those who are aware are more likely to take advantage of
these incentives (53 vs. 46 percent).

Traveling During Off‐Peak Periods
Similarly, there were fewer respondents aware that I‐70 corridor businesses offer incentives to
travel at off‐peak times in 2017 than in 2014 (9 vs 16 percent). However, among those who are
aware, they are more likely to check out these deals on I‐70 (32 vs. 29 percent). However, they
are less likely to actually take advantage of peak time deals –only 1 percent of respondents say
they have, which may indicate that these deals are not considered as attractive among those
familiar with them.

Ideas for Improving Traffic Flow Along the I‐70 Corridor
QUALITATIVE INSIGHTS A final question to the survey asked respondents, “What idea do you think has the most potential to improve traffic flow along the I‐70 corridor?” Again, a wide variety of ideas were proposed and should be read in full. However, the most common suggestions include:
Add more lanes o “Widen road in more areas to add lanes”
Enhance promotion/marking around incentives and options o “Promote the carpooling incentives! I did not know about them.”
Offer public transportation options o “A ski train to Summit County at least. Maybe all the way to Vail/ Beaver
Creek. Everyone I know would take it. More driving lanes are just a bandaid. We need a long term solution.”
Restrict commercial vehicles o “Limit semi trucks during peak times!”
