Objectives and Methodology
4
Objectives
  • Assess awareness of HOV lanes
  • Determine level of support and usage of HOV lanes
  • Assess perceptions and imagery of HOV lanes
  • Assess perceived benefits and importance of
    benefits of the lanes
  • Better understand HOV usage by comparing current
    users to commuters who could use the HOV lanes
    but do not
  • Assess perceptions of lane enforcement
  • Identify barriers to usage and ways that these
    barriers can be overcome

5
Methodology
  • A telephone survey was conducted among commuters
    in Northern Virginia who travel on the Dulles
    Toll Road, I-95, I-395 or I-66
  • Some respondents currently use the HOV lanes, and
    some do not use the HOV lanes but could
  • Non-users had to travel a sufficient distance for
    HOV lanes to be beneficial. Commuters on I-95
    and I-395 had to travel for at least 30 minutes
    to qualify. Commuters on DTR and I-66 had to
    travel for at least 20 minutes
  • For non users, HOV lanes had to be conveniently
    accessible to them
  • In addition, all respondents had to
  • Be aged 18 - 65
  • Commute at least 3 days a week during morning
    rush hour on DTR, I-95, I-395 or I-66

6
Methodology
  • 1,800 interviews were targeted for completion.
    These interviews were to include 200 HOV users on
    each of the corridors DTR, I-95, I-395 and
    I-66. The sample was also designed to include
    non HOV users 200 each on I-95 and I-395 and
    400 each on DTR and I-66.
  • 1,817 interviews were completed, distributed as
    follows

  • The typical morning commute for some commuters
    involves more than one of these corridors. Thus,
    some respondents are represented more than once
    in these categories.

Importance Index
  • Respondents who rideshare were asked their first
    and second most important reasons for
    ridesharing.
  • An Importance Index was created by assigning 2
    points for every first place mention and 1 point
    for every second place mention.
  • The points were totaled for each attribute (or
    reason). Then, the points for all attributes
    were totaled. The proportion of the total
    accumulated for each attribute represents that
    attributes Importance Index. This value
    represents each attributes relative importance
    in deciding to rideshare.

Conclusions and Implications
90
Conclusions and Implications
  • Conclusion Commuters on I-95 and I-395 are more
    likely than commuters on DTR and I-66 to select
    transportation alternatives that allow them to
    utilize the HOV lanes. In particular, they are
    more likely to commute in pre-arranged carpools
    with two or more others, to commute in informal
    carpools (slugs) and to commute in vanpools. In
    addition, these HOV users on I-395 and I-95 are
    more likely to work for the federal government
    and are more likely to work for employers that
    support HOV through incentive programs.
    Additionally, they are often commuting farther
    distances than non HOV users and are realizing
    greater time savings by using the HOV lanes.
  • Implication When numerous conditions that
    support or encourage usage of the HOV lanes come
    together or coalesce, the greater the
    likelihood that commuters will select a
    transportation alternative that allows them to
    use the HOV lanes. It may be that one of these
    factors acting alone e.g., distance traveled,
    time savings may be sufficient to increase the
    likelihood for using the HOV lanes. The combined
    effect of several factors, however, could bring
    the likelihood even higher. Explore ways of
    combining messages and incentives for using the
    HOV lanes to increase the likelihood of selecting
    a transportation option that allows the use of
    the HOV lanes.

91
Conclusions and Implications
  • Conclusion Commuters choose to HOV because it
    saves them time. When asked directly, in an
    open-ended question, why they use the HOV lanes,
    nearly 6 out of every 10 HOV users said that they
    HOV because it saves them time. No other answer
    was mentioned with this degree of frequency.
    Commuters also indicated that avoiding traffic
    congestion (11) and heavy traffic (7) and not
    having to drive (5) were important reasons for
    using the HOV lanes. Together, these reasons
    were more important than cost savings (11).
  • Implication Commuters have heard and responded
    to the message that the HOV lanes will allow them
    to save time on their commute. These commuters
    may be the easiest to convert and receptive to
    the saving time message. While this message
    may continue to convert additional commuters to
    HOV lane usage, it may be that future converts to
    HOV usage may respond better to other messages.
    These messages may include concepts related to
    less traffic congestion and reducing stress.
    Explore how new messages or messages in addition
    to save time can be used to persuade commuters
    to use the HOV lanes.

92
Conclusions and Implications
  • Conclusion Commuters who do not use the HOV
    lanes have slightly different perceptions of the
    lanes particularly in terms of benefits than
    do those who use the HOV lanes. Those who do not
    use the HOV lanes are less likely to believe that
    HOV lanes get commuters to their destinations
    faster, that they lower transportation costs,
    that they move more people in fewer vehicles,
    that they improve air quality, that they relieve
    traffic congestion, and that the HOV lanes are
    safer.
  • Implication Commuters who do not use the HOV
    lanes have resisted belief in the benefits of the
    HOV lanes or have resisted the messages about
    the benefits of the HOV lanes. Explore ways of
    making the benefits of using the HOV lanes more
    persuasive. Assess the extent to which emotional
    rather than rational messages or some
    combination of both emotional and rational can
    be used to convince additional commuters in
    Northern Virginia to use the HOV lanes. For
    example, a message about time savings save 15
    minutes on your commute tends to be rational.
    Develop ways to communicate this message in more
    emotional ways.

93
Conclusions and Implications
  • Conclusion In general, commuters do not believe
    that the HOV lanes are enforced regularly. Only
    41 of those who do not use the HOV lanes and 37
    of those who do HOV believe that the lanes are
    enforced regularly.
  • Implication Lack of perceived enforcement of
    the HOV lanes may lead commuters to believe that
    the lanes not supported by VDOT or legal
    authorities and, hence, not important. This
    perception could prevent adoption of
    transportation that would allow usage of the HOV
    lanes. Lack of enforcement may also convince non
    users that not using the HOV lanes is justified
    because it allows them to rationalize their
    decision not to HOV. As long as those who do not
    use the HOV lanes believe that the restrictions
    are not enforced, they will be difficult to
    convert to transportation options that allow them
    to use the HOV lanes.

94
Conclusions and Implications
  • Conclusion There is no clear understanding
    among commuters about the penalty for violation
    of HOV restrictions. One-third of commuters
    (34) said simply that they did not know what the
    penalty is. Non HOV users are slightly more
    likely to indicate that they do not know what the
    penalty is. Some commuters believe there is a
    fine or ticket for violation, but do not know the
    amount. Others think the fine ranges from 25 to
    500.
  • There is support for more strict enforcement of
    the HOV lanes, particularly among those who
    already use the HOV lanes. Nearly three-fourths
    (72) of current HOV users believe the lanes
    should be enforced more fully. Six out of ten
    (59) commuters who do not currently use the HOV
    lanes also support more strict enforcement of the
    lanes.
  • Implication In order for penalties for
    violation of the lanes to be effective to
    attract more qualified users and discourage
    illegal usage commuters must know that there
    are penalties for violation, what the penalties
    are, and that they are enforced. Consider a
    campaign or specific messages that communicate
    the penalties for HOV lane violation. Since
    there is already support for more strict
    enforcement of the lanes, a message clarifying or
    reiterating the penalties would be welcomed by
    many.

95
Conclusions and Implications
  • Conclusion Commuters who do not use the HOV
    lanes are aware of the lanes. Approximately 98
    of all commuters who do not use the HOV lanes
    currently are aware of the lanes. However, not
    all non HOV users are familiar with the lanes.
    Only about 75 of the non users said that they
    are familiar with the HOV lanes in terms of
    knowing the hours of operation and the location
    of the exits and entrances.
  • Implication Lack of awareness is not preventing
    usage of the HOV lanes. Lack of understanding
    and hence lack of comfort and ease of usage may
    be preventing usage of the HOV lanes. An
    important role of communications is education.
    Explore ways to educate commuters about the HOV
    lanes in ways that make the lanes seem easy to
    use and increase the commuters comfort with
    using the HOV lanes.

96
Conclusions and Implications
  • Conclusion The most frequent reason given for
    not using the HOV lanes is that commuters do not
    know of anyone going my way. Over one-fourth
    (28) of commuters who do not use the HOV lanes
    said that they do not HOV because they know of no
    one going the same way.
  • Implication Communications should not neglect
    the importance of a message about the
    availability of resources to help commuters find
    other commuters who might HOV with them.
    Emphasize the ease and speed with which these
    services can be used.

97
Conclusions and Implications
  • Conclusion Among commuters who currently SOV,
    there is interest in commuting in a carpool or
    vanpool for a monetary incentive. Nearly
    one-fourth (22) of commuters would be likely to
    carpool if paid .50 a day. Commuters on I-95
    are most interested in carpooling under these
    conditions. Twenty-nine percent (29) of this
    group would be likely to carpool if paid .50 a
    day. Slightly fewer, 19, would be likely to
    vanpool if paid .50 per day. Commuters on I-95
    (27) are also more likely to respond to this
    .50 incentive to vanpool than commuters on DTR,
    I-395 or I-66.
  • Implication Potentially, nearly one-fourth of
    SOV commuters could be converted to carpooling or
    vanpooling with monetary incentives. Recognize
    that not all who say they will carpool or vanpool
    actually will. Explore ways to best convert
    these potential HOV commuters to actual HOV
    commuters through optimal messages and
    operational logistics (e.g., how money is paid).
    Start with SOV commuters on I-95 where the
    potential is greatest.

98
Conclusions and Implications
  • Conclusion HOV users (68) are more likely than
    non HOV users (52) to be aware that there is a
    Park-n-Ride lot convenient for them to use. This
    pattern holds constant across all corridors in
    Northern Virginia DTR, I-95, I-395, and I-66.
  • Implication The awareness of the availability
    of Park-n-Ride lots is positively related to
    usage of the HOV lanes. It is important to have
    Park-n-Ride lots conveniently available, and it
    is important for commuters to be aware of and
    familiar with Park-n-Ride lots. Continue to
    inform commuters about Park-n-Ride lots,
    including raising awareness and understanding of
    the lots.

99
Conclusions and Implications
  • Conclusion Currently, about 20 of commuters
    telework whether they also HOV or not. Among
    those who do not currently HOV or telework, there
    is interest in teleworking in the future. Those
    who currently do not use the HOV lanes are
    significantly more likely to say that they will
    telework in the future than are those who
    currently use the HOV lanes, 47 likelihood among
    non HOV users and 32 likelihood among HOV users.
  • Implication Multiple solutions are necessary to
    ease traffic congestion in Northern Virginia.
    Some non HOV users may never HOV. Nevertheless,
    they might opt to telework. Some current non HOV
    users may chose to both telework and HOV. Find
    ways to target messages about the opportunity and
    process of teleworking to current non HOV users.
    Develop finely tuned messages to convert these
    commuters who are already interested in
    teleworking.

Conclusions and Implications
  • Conclusion Commuters on DTR, I-95, I-395, and
    I-66 are aware of and rely on multiple sources of
    information for help in navigating through the
    traffic of Northern Virginia. They are most
    aware of television news reports, radio news
    reports and newspaper articles. They also rate
    these sources of information about HOV lanes to
    be most helpful primarily because these sources
    keep them updated and provide traffic reports.
    Although fewer commuters are aware of the HOV
    website, it receives highly favorable ratings in
    terms of the usefulness of the information
    provided by the site.
  • Implication Continue to use multiple media to
    reach commuters in Northern Virginia, layering
    media vehicles and messages to achieve maximum
    effectiveness. Explore ways to raise the level
    of awareness of the website a particularly
    effective way to communicate with the
    internet-savvy commuters of Northern Virginia.
