    SUPPLEMENTARY INFORMATION:
        Title: Motorcycle Crash Causation Study and Pilot Motorcycle Crash
    Causes and Outcomes Study.
        Background: In 2004, 4,008 motorcyclists were killed and 76,000
    were injured in traffic crashes in the United States, increases of 8
    percent, and 14 percent respectively from 2003. Per vehicle mile
    traveled in 2003, motorcyclists were about 32 times more likely to die,
    and 6 times more likely to be injured in a motor vehicle crash than
    were passenger car occupants. Per 100 million miles traveled, in 2003,
    motorcyclist fatalities were 57 percent higher than they were in 1993.
    This compares with a decrease of 17.8 percent in fatality rates for
    occupants in passenger vehicles over the same period. These data show
    that the motorcycle crash problem is becoming more severe.\1\
    ---------------------------------------------------------------------------

        \1\ More detailed information on motorcycle crashes can be found
    in Traffic Safety Facts--Motorcycles, published by NHTSA and
    available on its Web site at: http://www.-nrd.nhtsa.dot.gov/pdf/nrd-30/NCSA/Rpts/2006/810606.pdf
    .

    ---------------------------------------------------------------------------

        Congress has recognized this problem and directed the Department of
    Transportation to conduct research that will provide a better
    understanding of the causes of motorcycle crashes. Specifically, in
    Section 5511 of the Safe, Accountable, Flexible, Efficient
    Transportation Equity Act: A Legacy for Users (SAFETEA-LU) Pub. L. 109-
    59, Congress directed the Secretary of Transportation to provide grants
    to the Oklahoma Transportation Center (OTC) for the purpose of
    conducting a comprehensive, in-depth motorcycle crash causation study
    that employs the common international methodology for in-depth
    motorcycle crash investigation developed by the Organization for
    Economic Cooperation and Development (OECD).\2\ SAFETEA-LU authorized
    $1,408,000 for each of fiscal years 2006 and 2007, but provided for an
    equal match by the Grantee (Sections 5511 and 5101). The Secretary
    delegated authority to FHWA for the Motorcycle Crash Causation Grants
    under Section 5511 (71 FR 30831).
    ---------------------------------------------------------------------------

        \2\ The OECD methodology may be obtained by sending a request to
    jtrc.contact@oecd.org
    .

    ---------------------------------------------------------------------------

    Coordination of FHWA Main Study and NHTSA Pilot Study

        Prior to the SAFETEA-LU directive by Congress to administer a full-
    scale study of motorcycle crash causes, NHTSA awarded a contract to
    conduct a pilot study of Motorcycle Crash Causes and Outcomes. The
    intent of this pilot study is to examine appropriate applications of
    the OECD methodology to motorcycle crashes in the United States. This
    pilot test is needed before any full-scale study could be conducted
    because the OECD methodology has not previously been implemented in the
    United States, and also because this methodology incorporates some
    options for collecting crash and control sample data that are affected
    by logistical and budget constraints.
        The authorization of funds by Congress for a full-scale motorcycle
    crash study provided an opportunity for the NHTSA pilot study to become
    closely coordinated with the FHWA main study. As a result, the pilot
    study will test the procedures FHWA will consider using as it
    implements the OECD methodology. Additionally, it may be possible for
    the pilot study to transition directly into the main study, thereby
    allowing the main study to avoid many startup costs (e.g., site
    selection, training, coding manual development, data form development,
    etc.) that it otherwise would have incurred. This will allow the main
    study to capture a larger sample of crashes with the available funding.
    Recognizing these advantages, the Department of Transportation intends
    to submit a single request to OMB for approval of both of these
    studies. This notice is the first step in that combined approval
    request.

    Project Working Group Guidance

        A project working group consisting of representatives from the
    motorcycle industry and from the motorcycle community was formed to
    provide input into the study design. A working group meeting was held
    in Denver on June 15-16, 2006. At this meeting, consensus was reached
    that all the relevant OECD variables would be captured in both the
    NHTSA pilot and FHWA full-scale studies, that some of these variables
    would need to be modified to conform to U.S. requirements, and that
    other variables would need to be added to provide necessary data
    related to the U.S. roadway environment.

    Proposed Data Acquisition Methodology

    Use of Parallel and Complementary Procedures

        The OECD describes two complementary procedures to be performed for
    acquiring the data needed to understand the causes of motorcycle
    crashes. The first of these is the traditional in-depth crash
    investigation that focuses on the sequence of events leading up to the
    crash, and on the motorcycle, rider, and environmental characteristics
    that may have been relevant to the crash. The second procedure, known
    as the case-control procedure, complements the first. It requires the
    acquisition of matched control data to allow for a determination of the
    extent to which rider and driver characteristics, and pre-crash factors
    observed in the crash vehicles, are present in similarly-at-risk
    control vehicles.
        Such a dual approach offers specific advantages to the
    understanding of crashes and the development of countermeasures. The
    in-depth study of the crash by itself allows for analysis of the events
    antecedent to the crash, some of which, if removed or altered, could
    result in a change in subsequent events that would have led to a non-
    crash, or reduced crash severity outcome. For example, an in-depth
    crash investigation may reveal that an automobile approaching an
    intersection was in a lane designated for straight through traffic
    only, but the motorist proceeded to make a left turn from that lane
    into the path of an oncoming motorcycle. That finding can, by itself,
    be used to develop countermeasures, and does not require matched
    control data. However, acquiring matched control data from similarly-
    at-risk riders and drivers provides additional critical information
    about crash causes that cannot be obtained if only crashes are
    examined. The main purpose of acquiring matched data is to allow for
    inferences to be made regarding risk factors for crash causes. A brief
    explanation is provided here so that those less familiar with case-
    control procedures will understand the

    [[Page 67954]]

    advantage of acquiring controls.\3\ Consider a hypothetical situation
    where it is observed that the proportion of motorcycle riders involved
    in crashes that have a positive Blood Alcohol Content (BAC) is the same
    as the proportion of matched (similarly-at-risk) control motorcycle
    riders not involved in crashes. And assume that the proportion of
    passenger-vehicle motorists who crash with motorcycles at a positive
    BAC is greater than matched control passenger-vehicle motorists. These
    data considered together would suggest that for crashes involving
    passenger vehicles and motorcycles, alcohol is a bigger risk factor for
    passenger vehicle drivers than it is for motorcycle riders. That is,
    the relative risk of crash involvement attributable to alcohol in
    motorcycle-automobile crashes is greater for passenger-vehicle
    motorists than for motorcyclists. Other risk factors for crashes (i.e.,
    age, gender, riding and driving experience, fatigue level) for both
    motorcyclists and motorists can also be examined in this manner. If
    scaled interval measurements of risk factor levels are obtained (for
    example, if the level of alcohol is measured, not just its presence or
    absence), then it becomes possible to calculate functions showing how
    risk changes with changes in the variable of interest. Such risk
    functions are highly useful in the development of countermeasures.\4\
    ---------------------------------------------------------------------------

        \3\ This being a study of crashes involving motorcycles, data
    will be acquired from both crash-involved motorcycles and also motor
    vehicles involved in those crashes as countermeasures may be
    developed separately for each that could lead to a reduction in
    crashes involving motorcycles. Similarly, when control data are
    acquired, data from similarly-at-risk motorcycle rider controls and
    similarly-at-risk automobile driver controls will also be acquired.
    This way a balanced picture of the causes of crashes involving
    motorcycles and other vehicles will emerge.
        \4\ Certainly other outcomes besides the one presented are
    possible, and other comparisons are of interest. For example, it
    would be useful to compare crash-involved motorcyclists to non-crash
    involved motorcyclists and crash-involved passenger vehicle
    motorists to non-crash involved passenger-vehicle motorists. These
    comparisons would allow for estimates of changes in relative risks
    for riders and drivers independently.
    ---------------------------------------------------------------------------

    Issues Related to Sampling

    Characteristics of the Crash Sample
        To properly acquire in-depth crash data, it is necessary to find a
    location in the country that experiences the full range of motorcycle
    crash types that occur under a wide range of conditions and with a wide
    range of motorcycle rider characteristics. The location must also have
    a sufficiently high frequency of motorcycle crashes to allow
    acquisition of the crash data in a reasonable amount of time. It is
    anticipated that it will be possible to find a single location meeting
    these requirements.
        It is not necessary that the crash types observed (or other
    composite indices or parameters of interest) be drawn from a nationally
    representative sample, because it is not the intent of FHWA to make
    projections of the national incidence of the causes of crashes
    involving motorcycles from this study. Rather, the focus will be on
    identifying the antecedents and risk factors associated with motorcycle
    crashes. If it is deemed necessary, FHWA and NHTSA may utilize their
    alternative databases that incorporate certain of the key variables
    that will be acquired in this study, and those databases could be used
    in conjunction with this study's data to make national estimates of
    population parameters of interest.\5\
    ---------------------------------------------------------------------------

        \5\ There is a lengthy precedent for studying crashes using
    case-control methods including the Grand Rapids study, (Borkenstein,
    R.F., Crowther, F.R., Shumate, R.P., Ziel, W.B. & Zylman, R. (1974).
    The Role of the Drinking Driver in Traffic Accidents (The Grand
    Rapids Study). Blutalkohol, 11, Supplement 1), and of course the
    Hurt study, (Hurt, H.H., Jr., Ouellet, J.V., and Thom, D.R. (1981).
    Motorcycle Accident Cause Factors and Identification of
    Countermeasures Volume I: Technical Report).
    ---------------------------------------------------------------------------

        In addition, the crash investigations will be conducted on-scene,
    while the involved operators and vehicles are still in place. This
    provides access to physical data that is less disturbed by rescue and
    clean up activities. It also facilitates the collection of interview
    data while memories are unaffected. This quick-response approach is
    most effective when a census of applicable crashes is selected for
    inclusion.
    Characteristics of the Control Sample
        While the occurrence of a crash involving a motorcycle in the study
    site is sufficient for it to be selected into the study, selecting the
    similarly-at-risk controls is not as straightforward. The OECD
    recommends several options for acquiring matched controls including
    interviewing motorcyclists who may be filling up at nearby gas
    stations, taking videos of motorcyclists who pass the crash scenes, and
    interviewing motorcyclists at the location of the crash location at the
    same time of day, same day of week, and same direction of travel. The
    first of these methods suffers from the shortcoming that a rider or
    motorist filling his fuel tank is not presented with the same risks, in
    the same setting, as is the crash-involved rider and motorist. To
    illustrate, consider a motorcycle rider who is hit from the rear by a
    passenger vehicle motorist on a Friday night at 1:00 a.m. There is a
    reasonable chance that alcohol is involved in this crash, but to
    estimate the relative risk it will not help to measure the BAC of
    passenger vehicle motorists (and motorcyclists) at a nearby gas
    station. Passenger-vehicle motorists and motorcyclists will need to be
    sampled at the location of the crash on the same day of the week, at
    the same hour, and from the same travel direction. Even if the
    suspected risk factor is not alcohol, but some other variable (e.g.,
    distraction associated with cell phone use), it is still highly
    advantageous to acquire the comparison data at the crash locations
    (matched on time and direction), rather than somewhere else.
        Using the second method mentioned above, acquiring the risk sample
    by taking video at the crash scenes provides a similarly-at-risk pool,
    and it also allows for many controls to be acquired at low cost. Its
    chief disadvantage is that it does not allow capture of some of the key
    risk factors for crashes (e.g., BAC), while others (e.g., fatigue) may
    be very difficult to capture. However, some risk factors could be
    acquired later by contacting the riders and drivers if license tag
    numbers are recorded, and so this method could be used to supplement
    the safety zone interview (described below).
        The final method, the voluntary safety research interview, involves
    setting up a safety zone at the crash location, one week later at the
    same time of day, and asking those drivers and motorcyclists who pass
    through to volunteer in a study. With this method, Certificates of
    Confidentiality are presented to each interviewed driver and rider and
    immunity is provided from arrest. The main advantage of this method is
    that the key variables that are thought to affect relative crash risk
    can be acquired from drivers and riders who are truly similarly-at-
    risk. A final decision on the means of acquiring control data has not
    been made.

    Information Proposed for Collection

        The OECD protocol includes the following number of variables for
    each aspect of the investigation:

    Administrative log: 28
    Accident typology/configuration: 9
    Environmental factors: 35
    Motorcycle mechanical factors: 146
    Motorcycle dynamics: 32
    Other vehicle mechanical factors: 9
    Other vehicle dynamics: 18
    Human factors: 51
    Personal protective equipment: 34
    Contributing environmental factors: 8
    Contributing vehicle factors: 13
    Contributing motorcycle factors: 57

    [[Page 67955]]

    Contributing human factors: 50
    Contributing overall factors: 2

        Note that multiple copies of various data forms will be completed
    as the data on each crash-involved vehicle and person and each control
    vehicle and person are acquired. This increases the number of variables
    above the sum of what is presented above. There are also diagrams and
    photographs that are essential elements of each investigation that are
    entered into the database. In prior OECD implementations, about 2,000
    data elements in total were recorded for each crash.

    Estimated Burden Hours for Information Collection

        Frequency: This is a one time study.
        Respondents: This study will be based on all crashes occurring
    within the sampling area; however, this burden estimate is based on
    what we know about fatal crashes. The plan calls for data to be
    captured from up to 1200 crashes with motorcycle involvement, and for
    all surviving crash-involved riders and drivers to be interviewed. Two
    control riders will be interviewed for each crash-involved
    motorcyclist, and one rider and one driver will be interviewed for each
    rider and motorist in multi-vehicle crashes. Passengers accompanying
    crash-involved riders and passenger-vehicle drivers will also be
    interviewed. The following table shows the sampling plan and estimated
    number of interviews assuming 1200 crashes are investigated.\6\
    ---------------------------------------------------------------------------

        \6\ The final crash sample size will depend on the rate at which
    crashes can be acquired in the selected site(s) and other matters
    related to logistics and the final budget. However, the study will
    acquire crashes on a sample size that exceeds the requirements of
    the OECD methodology, and will be of sufficient size to meet the
    goals of the study.
    ---------------------------------------------------------------------------

        Maximum total crashes to be investigated is 1200.

    Crash Interviews
        Single vehicle motorcycle crashes = 540
        Multi-vehicle (2-vehicle) motorcycle crashes (660*2) = 1320
        Passenger interviews motorcycle (.10* 540 + .10*660) = 120
        Passenger interviews cars (.68*660) = 449
        Total Crash Interviews (540+1320+120+449) = 2429
    Control interviews
        Controls for single vehicle motorcycle crashes (2*540) = 1080
        Controls for multi-vehicle motorcycle crashes (1*660 + 1*660) =
    1320
        Passenger Interviews = 0
        Total Control Interviews = 2400
    Grand Total Crash plus Control Interviews (2429+2400) = 4829

        Estimated Average Burden per Interviewee: Crash interviews are
    estimated to require about 15 minutes per individual interviewed To the
    extent possible, crash interviews will be collected at the scene,
    although it is likely that some follow-ups will be needed to get
    completed interviews from crash involved individuals. Control
    individuals' interviews will be completed in a single session and are
    expected to require about 10 minutes per individual.
        Estimated Total Annual Burden Hours: Burden hours estimates are
    based on the total of 2,429 crash interviews to be conducted at an
    average length of 15 minutes each and 2,400 control interviews to be
    conducted at an average length of 10 minutes each for a total one-time
    burden on the public of 60,435 minutes or 1007.25 hours.
        Public Comments Invited: You are asked to comment on any aspect of
    this information collection, including: (1) Whether the proposed
    collection is necessary for FHWA's and NHSTA performance; (2) the
    accuracy of the estimated burden, (3) ways for the FHWA and NHTSA to
    enhance the quality, usefulness, and clarity of the collected
    information; and (4) ways that the burden could be minimized, including
    the use of electronic technology, without reducing the quality of the
    collected information. The agency will summarize and/or include your
    comments in the request for OMB's clearance of this information
    collection.
