OVERALL PURPOSE:
This research was designed to help guide the development
and formulation of a context-sensitive solution to managing congestion in the
I-66 Westbound corridor.
OBJECTIVES OF RESEARCH:
Describe and document trips Westbound along the I-66
corridor.
Identify and assess stakeholder perception of traffic
congestion in the Westbound I-66 corridor.
Assess relative appeal of four initial concept categories
that the Governor identified: bus or rail improvements, changing the
requirements for HOV and/or adding toll lanes, roadway widening, or do nothing.
METHODOLOGY:

Mode of Data Collection |
Telephone survey |

Completed Interviews |
501 |
|
Survey Population |
Residents along the I-66 corridor |
|
Survey Instrument |
Questionnaire administered by telephone interviewer |
|
Criteria for Participation |
Respondents had to live within a 10-mile long / 1-mile
wide corridor of I-66. All
respondents traveled Westbound at least 3 times per week, using either I-66,
Metro or other roads running parallel to I-66. |
SELECTED KEY FINDINGS:
Westbound
commuters along the I-66 westbound corridor believe that westbound traffic in
the corridor is becoming more congested.
Approximately 77% of commuters believe that Westbound
traffic in the I-66 corridor is becoming more congested.
Both
residents inside the Beltway (69%) and outside (88%) believe the I-66 corridor
is becoming increasingly congested.
Stakeholders
blame increased congestion on the number of cars on the road, not having enough
lanes on the road and population growth and development.
Approximately 38% of commuters believe the congestion is
the result of too many cars, and approximately 27% believe there are not enough
lanes for Westbound traffic.
Half of
commuters (52%) propose widening lanes to resolve traffic congestion. One-third (33%) of commuters propose
improving public transportation/expanding Metro to resolve traffic congestion.
Of four
concepts tested, the two most popular were:
make bus and/or rail transit improvements and roadway widening. Nearly half, 47%, of commuters selected bus
and/or rail transit improvements their first choice to reduce I-66 Westbound
congestion. About 37% of commuters
selected roadway widening as their first choice to reduce I-66 Westbound
congestion.
A
Concept Performance Index was calculated for the four concepts tested. On this index, bus and/or rail transit
improvements ranked highest among commuters (36 points out of a possible 100),
but this option was not overwhelmingly preferred over roadway widening (29
points) or changing the requirements for HOV and/or adding toll lanes (25
points).
Overwhelmingly,
residents want some kind of action - only 10% of commuters said that “doing
nothing” was their first choice.
From the perspective of stakeholders, making “bus and/or
rail improvements” should be adopted as a plan – or at least as part of a plan
– to reduce traffic congestion on Westbound I-66. Widening the roadway is also a strong contender and should be
included as part of a plan that is responsive to the needs and preferences of
stakeholders. Ideally, a plan that
involves both bus and rail improvements and widening the roadway would
be a context-sensitive solution.
