Introduction
The Motor Carrier Safety Improvement Act of 1999 (MCSIA), P.L. 106-159, mandated a study to
determine the causes of, and contributing factors to, commercial motor vehicle crashes. The U.S.
Department of Transportations (DOT) Federal Motor Carrier Safety Administration (FMCSA) and
National Highway Traffic Safety Administration (NHTSA) conducted a multiyear, nationwide study
of factors that contribute to truck crashes. The Large Truck Crash Causation Studys (LTCCS)
goal is to identify effective crash countermeasures.
The LTCCS was conducted at 24 data collection sites in 17 States by researchers from NHTSAs
National Automotive Sampling System (NASS) and State truck inspectors. Crash data were
coded in two NASS quality control Zone Centers and reviewed by FMCSA and NHTSA personnel
and national truck crash experts.
The LTCCS collected data on crashes from 2001 through 2003. An attempt was made to ensure
that each crash involved at least one large truck with a gross vehicle weight rating of more than
10,000 pounds, and resulted in at least one fatality or at least one incapacitating or non-
incapacitating but evident injury. Data were collected on up to 1,000 elements in each crash. To
get the highest quality data possible, the onsite investigations began as soon as possible after the
crash occurred. Data collection was performed at each crash site by a two-person team
consisting of a trained researcher and a State truck inspector. Researchers collected data at
crash scenes through driver, passenger, and witness interviews.
Subsequent to the crash, each truck and truck driver were subjected to a thorough inspection.
After leaving the crash scene, researchers collected additional interview data by telephone from
motor carriers responsible for the trucks and surrogate drivers of trucks and other vehicles when
the actual drivers could not be interviewed as a result of a fatal or serious injury. Researchers
also reviewed police crash reports, hospitals records, and coroners reports. In addition,
researchers often revisited the crash scene to make more accurate scene diagrams and search
for additional data.
Together the teams collected data on approximately 1,000 variables on each crash. Crash case
data were provided to NHTSA crash experts for coding, difficult cases were reviewed by NHTSA
and FMCSA headquarters staff, and finalized cases were sent to DOTs Volpe National
Transportation Systems Center for inclusion in the studys electronic database.

Programmers' Introduction to the LTCCS User's Manual and Data
Table Design
There are 1070 crashes documented in the Large Truck Crash Causation Study (LTCCS)
database. Each of these is assigned a unique CaseID. There were 2284 vehicles involved in the
study crashes, each of which is assigned a VehicleNumber (from 1 to 30). Any vehicle in the
database can be uniquely identified by CaseID and VehicleNumber. There are 3014 vehicle
occupants and 53 non-motorists in the study. Each occupant is assigned an OccupantNumber
(from 1 to 11). Each non-motorist is assigned a NonMotoristNumber (from 1 to 7). Occupants
can be uniquely identified by CaseID, VehicleNumber, and OccupantNumber, and non-
motorists by CaseID and NonMotoristNumber. The database further identifies 2777 distinct
events, each of which is one in a sequence of events which occur in the course of a crash. Each
of these events can be uniquely identified by CaseID and EventSequence.
When joining (i.e. merging) tables one must match those elements which uniquely identify
records in the table, e.g. joining the VehicleEvents table with the GeneralVehicle table
requires matching by common CaseID and VehicleNumber.
There is one crash-level table, Crash and each row in this table corresponds to a single crash.
This is the single most general, or "top-level" table. All other tables give finer levels of detail, with
multiple rows per crash. The level of detail of the rows of a particular table can be determined by
the introduction to the table given in the User's Manual. A description of the variables which must
be taken together to uniquely identify each record are also given there.
Variable Reference
The LTCCS database (LTCCS DB) is released in three formats, SAS, MS-Excel, and plain text.
Many of the values in the LTCCS DB are numeric codes corresponding to some meaningful value
description. These values are captured by the SAS version of the LTCCS DB, but not the MS-
Excel or text versions. To assist users of the study data, a LTCCS DB Variable Reference table
has been created for the Excel and text versions, which lists the LTCCS tables and variables with
their code values and descriptions. By using this Variable Reference one may determine the
meaning of a particular variable code value. This reference is automatically included in both the
MS-Excel and text format download packages.
Avoiding Difficulties
It is recommended that the User's Manual be consulted carefully, rather than relying on intuitive
interpretations of variable names. Most variables have integer values. In some cases these are
literal values, e.g. counts. In others, these values are codes representing some other value which
can be found in the variable reference. For example, the variable OCCFatality in dataset
Crash does not represent the number of fatalities in the crash, but rather, whether there were
any fatalities, as well as whether any fatalities were ruled due to disease rather than injury.
Vehicle body type is identified by GVEBodyType in the GeneralVehicle dataset. By the
methodology of the LTCCS large trucks are those with values for GVEBodyType = {60, 61, 62,
63, 64, 66, 67, 68, 69, 70, 74, 78}.

Examples
All Trucks, Simple Count
This algorithm obtains a simple, un-weighted count of the large trucks involved in the LTCCS. It
demonstrates how to use the GVEBodyType variable to identify a particular vehicle as a large
truck, and how to use the RATWeight variable to filter out invalid cases. Only cases with a
positive RATWeight are valid for the purpose of the study. Invalid cases were included for
purposes of qualitative analysis.
1) Access GeneralVehicle table.
2) Select only cases with values for GVEBodyType = {60, 61, 62, 63, 64, 66, 67, 68, 70, 74,
78}. Depending on the programming environment used this may be more easily implemented by
selecting cases where (GVEBodyType >= 60 & GVEBodyType <= 78 & GVEBodyType <> 65).
3) Select only cases with values for RATWeight > 0.
4) Count all remaining cases. This gives the unweighted number of large trucks in the LTCCS.
5) Sum all values for RATWeight. This gives the weighted number of large trucks involved in
serious crashes nation-wide.
There are 1123 large trucks in the LTCCS. There are an estimated 141,200 large trucks involved
in serious crashes nation-wide over the 33 month study period.
Trucks by Vehicle Configuration
The purpose of this table is to categorize large trucks involved in the LTCCS by vehicle
configuration type, e.g. single-unit or tractor-trailer, and to give unweighted counts of the number
of large trucks in each category. Single-unit vehicles are classified by their number of axles.
Combination vehicles by the number of trailers being towed.
1) Access TruckUnits table.
2) Mark all vehicles with at least one value of AxlesUsed = {7, 8, 9}.
3) Select only cases with values for RATWeight > 0.
4) Create variable AxleCt. If AxlesNotUsed <= 3 then set AxleCt = AxlesUsed +
AxlesNotUsed, else set AxleCt = AxlesUsed. Please note: values greater than three for
AxlesNotUsed are not valid counts of axles. They indicate that the axles were not inspected,
that this variable is not applicable, or that the count of axles not used is unknown.
5) Count number of axles for each vehicle by summing the number of axles for each unit
constituting that vehicle.
6) Perform inner join (i.e. merge) of results with Overview table.
7) Classify vehicles as follows:
a. Vehicles with a single unit, a value of OVEConfiguration = 'R', and AxleCt = 2 are
classified as "Single Unit - Two Axles",
b. Vehicles with a single unit, a value of OVEConfiguration = 'R', and AxleCt > 2 are
classified as "Single Unit - Three or More Axles",
c. Vehicles with a single unit, a value of OVEConfiguration = 'R', and the number of
axles is unknown (results from Step 2) are classified as "Single Unit - Axles Unknown",
d. Vehicles with a value of OVEConfiguration = 'Not Insp' are classified as
"Other/Unknown/Missing",
e. Vehicles with a value of OVEConfiguration = 'T' are classified as "Combo Truck -
Truck Tractor (bobtail)",
LTCCS Analytical User's ManualProgrammers' Introduction to the LTCCS User's Manual and Data  5

f. Vehicles with a value of OVEConfiguration = {'RF', 'RO'} are classified as "Combo
Truck - Truck Pulling Trailer(s)",
g. Vehicles with a value of OVEConfiguration = {'TO', 'TS', 'TSA'} are classified as
"Combo Truck - Tractor pulling Trailer",
h. Vehicles with a value of OVEConfiguration = {'TSAS', 'TSCS', 'TSF', 'TSXS'} are
classified as "Combo Truck - Tractor pulling Two Trailers",
i. Vehicles with a value of OVEConfiguration = {'ISS', 'ROO'} are classified as
"Other/Unknown/Missing" (please note that the two cases included here, one instance of
ISS and one instance of ROO may appear to fall under specific categories, but a review
of the case discussion, CrashDiscussion.Discussion, shows them both to be
unique and unusual cases and therefore valid instances of 'Other').
8) Sum vehicle counts in each classification and calculate percentage for each classification
by dividing its count by the total number of large trucks (1123).
Results are given in table 1 below.
Table 1. Trucks by Vehicle Configuration
Vehicle Configuration Unit Count Percentage
Single Unit - Two Axles 124 11.0%
Single Unit - Three Axles or more 157 14.0%
Single Unit - Axles Unknown 2 0.2%
Combo Truck - Truck Tractor  Bobtail 29 2.6%
Combo Truck - Truck Tractor(s) 40 3.6%
Combo Truck - Tractor pulling Trailer 697 62.1%
Combo Truck - Tractor pulling Two Trailers 54 4.8%
Other/Unknown/Missing 20 1.8%
Total 1123 100.0%
Trucks in Single-Vehicle Crashes by Critical Reason
These crashes involved only a single vehicle. In every case that vehicle was a large truck; no
passenger vehicles were involved in any of these crashes. The critical reason (ACRReason in
table CrashAssessment, and OVEReason in table Overview) is the immediate reason for the
critical event, which is the event that made the crash inevitable.
The numbers in the second column represent the rounded estimates of how often these factors
would be coded for all 141,200 estimated trucks involved in fatal and injury crashes that occurred
during the 33-month period of the study. When the program is run, it will provide unrounded
estimates. The numbers in this table have been rounded to the nearest 1,000 because they are
National estimates and subject to sampling and nonsampling errors. The percentages in the last
column are based on the unrounded estimates divided by 141,200 which is the unrounded
estimate of trucks involved in fatal and injury crashes during the 33 months.
1) Perform join (i.e. merge) of two tables, CrashAssessment and Crash using the CaseID
variable.
2) Select only cases with VehicleCount = 1.
3) Select only cases with values for RATWeight > 0. Please note: this step is optional.
Including this step will filter out large trucks which have zero weighting. There were 107 such
cases, which were surveyed as part of the study but given a weight of zero because they did not
meet the study criteria for one reason or another. These cases were still included in the study
dataset, however, as additional qualitative data.
LTCCS Analytical User's ManualProgrammers' Introduction to the LTCCS User's Manual and Data  6

4) For each value of ACRReason compute the sum of the values for RATWeight, i.e. group
cases by values of ACRReason and take the weighted counts. Calculate percentage by dividing
the weighted count by total weighted count.
Results for step 4 are rounded and given in Table 2 below.
5) Take results of 3) and take weighted counts of cases for each value of ReasonCat.
Calculate percentage for reason category by dividing its count by the total number of large trucks.
Results for step 5 are given in Table 3 below.

One Truck/One Passenger Vehicle Crashes, Associated Factors
One type of crash of particular interest to many investigators is the one truck/one passenger
vehicle (PV) crash. These include any crash in which the first two vehicles to collide were a large
truck and a passenger vehicle. This algorithm ignores vehicles involved in follow-on collisions.
Only the first two vehicles to collide are of interest here.
This algorithm describes compilation of a table showing the number of large trucks and
passenger vehicles in one truck/one PV crashes by five associated crash factors, 1) prescription
drug use, 2) traveling too fast for conditions, 3) braking system problem, 4) driver fatigue, and 5)
weather.
Two-vehicle crashes are included in this example only if one vehicle was a large truck, and the
other a passenger vehicle. One example of a two-vehicle crash not included in this example is a
two-vehicle crash involving two large trucks. Another example of a two-vehicle crash not included
in this particular example would be a two-vehicle crash involving a large truck and a motorcycle.
Additionally, multi-vehicle crashes are included in this example if and only if the first two vehicles
to collide are a large truck and a passenger vehicle. In such a crash, only those two vehicles are
included. Other vehicles involved in the pile-up are excluded from this particular example. The
complexities of this example require that the vehicles to be used in the example be selected in
two groups. The first group of vehicles are those involved in two-vehicle crashes. They are
identified in steps 1 - 5. The second group of vehicles are those involved in multi-vehicle crashes.
They are identified in steps 6 - 32. Step 33 merges these two groups of vehicles.
The primary tasks involved in compiling this table are, 1) Classification of the vehicles involved in
each event, 2) Identification of the two vehicles involved in the first collision, 3) Identification of
one truck/one passenger vehicle crashes, and 4) Identification and summation of the associated
factors relevant to all vehicles by vehicle type (i.e. truck versus passenger vehicle).
1) Join (i.e. merge) the GeneralVehicle and Crash data sets.
2) Select only cases for which VehicleCount = 2, TruckCount = 1, and CarCount = 1.
3) Classify vehicles as follows:
a. If 1 <= GVEBodyType <= 22, or 28 <= GVEBodyType <= 48, the vehicle is a Passenger
Vehicle (PV),
b. If 60 <= GVEBodyType <= 78 and GVEBodyType <> 65, the vehicle is a Truck,
c. All other vehicles are classified as Other.
4) Assign classifications to new variable called VehicleClass.
5) Save results keeping only CaseID VehicleNumber VehicleClass and RATWeight.
6) Join (i.e. merge) tables Events and GeneralVehicle by CaseID and VehicleNumber.

7) Classify vehicles as follows:
a. If 1 <= GVEBodyType <= 22, or 28 <= GVEBodyType <= 48, the vehicle is a Passenger
Vehicle (PV),
b. If 60 <= GVEBodyType <= 78 and GVEBodyType <> 65, the vehicle is a Truck,
c. All other vehicles are classified as Other.
8) Assign classifications to new variable called FirstVehicleClass.
9) Rename VehicleNumber to FirstVehicleNumber.

11) Access table Events.
12) Select only cases for which EVEObjectContacted <> 0 and
EVEObjectContacted <= 30.
13) Delete variable VehicleNumber.
14) Rename EVEObjectContacted to VehicleNumber.
15) Join (i.e. merge) results with table GeneralVehicle by CaseID and VehicleNumber.
16) Classify vehicles as follows:
a. If 1 <= GVEBodyType <= 22, or 28 <= GVEBodyType <= 48, the vehicle is a Passenger
Vehicle (PV),
b. If 60 <= GVEBodyType <= 78 and GVEBodyType <> 65, the vehicle is a Truck,
c. All other vehicles are classified as Other.
17) Assign classifications to new variable called SecondVehicleClass.
18) Rename VehicleNumber to SecondVehicleNumber.
19) Save results.
20) Join (i.e. merge) results of step 10) and step 19) by CaseID and EventSequence.
21) Select only cases with positive values for both FirstVehicleNumber and
SecondVehicleNumber.
22) Filter cases by selecting only the minimum value of EventSequence for each value of
CaseID.
23) Join (i.e. merge) results with Crash table.
24) Select only cases with values for RATWeight > 0. Please note: this step is optional. Including
this step will filter out large trucks which have zero weighting. There were 107 such cases, which
were surveyed as part of the study but given a weight of zero because they did not meet the
study criteria for one reason or another. These cases were still included in the study data set,
however, as additional qualitative data.
25) Select only cases for which VehicleCount > 2.
26) Select only cases in which one vehicle is of type Truck and the other vehicle is of type
Passenger Vehicle.
27) Save results.
28) Rename variable FirstVehicleClass to VehicleClass and rename
FirstVehicleNumber to VehicleNumber.
29) Save results keeping only CaseID VehicleNumber VehicleClass and RATWeight.
30) Access results from step 27).
31) Rename variable SecondVehicleNumber to VehicleNumber and rename variable
SecondVehicleClass to VehicleClass.
LTCCS Analytical User's ManualProgrammers' Introduction to the LTCCS User's Manual and Data  9

32) Save results keeping only CaseID VehicleNumber VehicleClass and RATWeight.
33) Concatenate results from steps 5), 29) and 32).
34) Join (i.e. merge) results with DriverDecisionAggression table by CaseID and
VehicleNumber.
35) Create variable TooFast. If Speeding = 1 or Speeding = 2 or Speeding = 3, then set
TooFast = RATWeight, else set TooFast = 0.
36) Save Results.
37) Access DriverDrugs table. Select only cases with DrugType = 1. This table consists of
one row per drug used by the driver prior to the crash. For some cases there are multiple
instances of prescription drug use by a driver. Eliminate repeat rows, i.e. there must be at most
one row with value of DrugType = 1 per driver.
38) Join (i.e. merge) results with results from step 36) by CaseID and VehicleNumber.
39) Create variable PrescripDrug. If DrugType = 1, then set PrescripDrug = RATWeight,
else set PrescripDrug = 0.
40) Perform join (i.e. merge) of results with FactorAssessment table by CaseID and
VehicleNumber.
41) Create variable BrakeFactor. If BrakeFailure = 1 or BrakesOutOfAdjustment = 1 or
BrakesInoperative = 1 or BrakesSystemDeficiency = 1, then set BrakeFactor =
RATWeight, else set BrakeFactor = 0.
42) Create variable WeatherFactor. If WeatherCount >= 1 and WeatherCount <= 6, then
set WeatherFactor = RATWeight, else set WeatherFactor = 0.
43) Join (i.e. merge) results with DriverAssessment table by CaseID and VehicleNumber.
44) Create variable DriverFatigue. If Fatigue = 1, then set DriverFatigue = RATWeight,
else set DriverFatigue = 0.
45) Group cases by VehicleClass. The weighted number of large trucks or passenger vehicles
in one truck/one passenger vehicle crashes that were speeding - or more specifically, traveling
too fast for conditions - is the sum of the variable TooFast. Similarly, summing PrescripDrug
yields the number of drivers taking prescription drugs. Summing BrakeFactor yields the
number of vehicles with faulty brakes. Summing WeatherFactor yields the number of vehicles
for which inclement weather was a factor (and as expected the number is the same for large
trucks and passenger vehicles). Summing DriverFatigue yields the number of vehicles driven
by fatigued drivers. Results are given below.
46) Note that results are rounded to nearest 1000. Percentages are calculated by dividing the
weighted count of vehicles per factor, by the total number of each type of vehicle involved in one
truck/one PV crashes (i.e. 65460.17).

CDCCrush Data Set
The CDCCrush data set contains the variables CaseID, PSU, PSUStrat, RATWeight,
VehicleNumber, EventNumber and ImpactNumber. EventNumber identifies a particular event in
a sequence in the accident. ImpactNumber identifies each particular impact in the crush profile
for a vehicle. CaseID, VehicleNumber, EventNumber and ImpactNumber uniquely identify each
record in this data set. (Each record can also be uniquely identified by CaseID, VehicleNumber,
EventNumber and PositionNumber.) CaseID and EventNumber should be used to merge the
CDCCrush data set with the Events data set. CaseID and VehicleNumber should be used to
merge the CDCCrush data set with vehicle level data sets. CaseID, VehicleNumber and
PositionNumber should be used to merge the CDCCrush data set with the TruckUnits data set.
This data set also contains the following variables:
Position Number
Definition: This variable identifies the unit number on the vehicle associated with a CDC/TDC.
For example, a truck-trailers power unit would be Position Number 1, and the first trailer would
be Position Number 2. A passenger vehicle would be assigned Position Number 1.

Crash Type
Definition: This variable is used in categorizing the collisions of drivers involved in crashes. A
collision is defined here as the first harmful event in a crash between a vehicle and some object,
accompanied by property damage or human injury. The object may be another vehicle, a person,
an animal, a fixed object, the road surface, or the ground. If the first collision is a rollover, the
impact is with the ground or road surface. The collision may also involve plowing into soft ground,
if severe deceleration results in damage or injury. A road departure without damage or injury is
not defined as a collision. This variable encompasses the Configuration variable, which is a
component of this variable. Cases where the crash type is No Impact include fire and
immersion.

Crash Configuration
Definition: This variable is used in categorizing the collisions of drivers involved in crashes. A
collision is defined here as the first harmful event in a crash between a vehicle and some object,
accompanied by property damage or human injury. The object may be another vehicle, a person,
an animal, a fixed object, the road surface, or the ground. If the first collision is a rollover, the
impact is with the ground or road surface. The collision may also involve plowing into soft ground,
if severe deceleration results in damage or injury. A road departure without damage or injury is
not defined as a collision. This variable is part of the larger variable Crash Type. The Crash
Type variable is actually broken down into three components: the crash category, the crash
configuration, and the accident type. This variable only deals with the configuration of the crash.

Definition: This variable documents whether or not the driver exhibited aggressive behavior in
terms of exceeding the speed limit by a minimum of 5 MPH (8.05 kmph) and the vehicles speed
has a bearing on subsequent crash events. A degree of caution is required when assigning this
element. Specifically, to be considered as a valid aggressive driving element, the act of speeding
should pose some risk to surrounding traffic. If, for example, the driver is speeding in a stream of
traffic, this act poses a risk to surrounding traffic. On the other hand, a driver who is speeding late
at night, on a rural highway with no surrounding traffic, does not pose a risk to others and should
not be considered as driving aggressively. (This variable was originally an attribute choice under
the variable Aggressive Driving Behavior.)

JackknifeAssessments Data Set
The JackknifeAssessments data set contains the variables CaseID, PSU, PSUStrat, RATWeight,
and VehicleNumber. CaseID and VehicleNumber uniquely identify each record in this data set
and should be used to merge the JackknifeAssessments data set with other vehicle level data
sets. This data set also contains the following variables:
Source: All variables in this table are determined by Case Reviewer using all available
information inputs. Primary sources include the scaled schematic, police report, driver interviews,
witness interviews, and vehicle inspection results.
Type Of Jackknife Event
Definition: This variable establishes the type of precrash jackknife event that is experienced by
the subject vehicle. In general, the type of jackknife event is determined by the unit of the
articulated combination that begins to rotate first. For example, if the tractor/cab unit is the first
unit to begin rotating, the event is generally considered a tractor jackknife. If, on the other hand,
the trailer unit is the first unit to begin rotating, the event is generally considered to be trailer
swing.

Variable Definitions and Codes - Occupants Data Set
Seat Belt Pretensioners Present
Definition: This variable identifies whether or not a seat belt pretensioner is present for a
manual belt. Pretensioners are designed to take up the slack in the seat belt during a crash of
sufficient deceleration. When the vehicle is involved in a collision of sufficient force, a
microprocessor causes current to flow through the seat belt deployment loops to the initiator.
Current passing through the intiator ignites the material in the canister, producing a rapid
generation of gas. The gas produced from this reaction deploys the seat belt pretensioners and
shortens the seat belt pretentioner height, which removes all of the slack in the seat belts. The
seat belt pretensioners will deploy immediately before the frontal initiator (air bag) modules
deploy.
Source: Researcher determined  primary source is vehicle inspection; secondary sources
include the interview and manufacturers data.

Vehicle Model Year
Definition: This variable establishes the model year that the vehicle was manufactured.
Source: Primary source is the VIN during vehicle inspection; secondary sources include the
police report and interviews.
Cross Reference: Identical to GeneralVehicle.GVEYear. Congruent with
GeneralVehicle.VINYear, values will differ due to VIN vs. Researcher determined values. Related
to TruckUnits.ManufactureDate if TruckUnits.TUNPosition =1 when applicable.

Truck Configuration
Definition: This variable provides a summary of the configuration of the rig. Letter codes are
strung together (listed from left to right) to represent the order of equipment in the rig. For
example, a tractor pulling two trailers connected by an A-dolly would have a configuration of
TSAS.
Source: Researcher determined  primary source is the vehicle inspection; secondary sources
include police or other vehicle photographs.

Pre-Event Movement
Definition: This variable establishes the subject vehicles pre-critical event movement pattern.
The pre-event movement pattern is usually described as the point that both precedes the critical
precrash envelope and that precedes vehicle motions that place the involved vehicle(s) on an
imminent collision path.
Source: Determined by the Case Reviewer using all available information inputs. Primary
sources include the scaled schematic, police report, driver interviews, and witness interviews. It
should be noted, however, that this may be a subjective decision based on the preponderance of
available evidence.
Cross Reference: Identical to CrashAssessment.PreEventMovement.

Critical Precrash Event
Definition: This variable identifies the event which made the crash imminent (i.e. something
occurred which made the collision inevitable). A precrash critical event is coded for each vehicle
in the crash and documents the circumstances leading to this vehicles first impact in the crash
sequence.
Source: Determined by the Case Reviewer using all available information inputs. Primary
sources include the scaled schematic, police report, driver interviews, witness interviews, and
vehicle inspection results. It should be noted, however, that this may be a subjective decision
based on the preponderance of available evidence.

Critical Reason For The Critical Precrash Event
Definition: This variable establishes the critical reason for the occurrence of the critical event.
The critical reason is the immediate reason for this event and is often the last failure in the causal
chain (i.e. closest in time to the critical precrash event). Although the critical reason is an
important part of the description of crash events, it is not the cause of the crash nor does it imply
the assignment of fault.
Source: Determined by the Case Reviewer using all available information inputs. Primary
sources include the scaled schematic, police report, driver interviews, witness interviews, and
vehicle inspection results. It should be noted, however, that this may be a subjective decision
based on the preponderance of available evidence.
Cross Reference: Identical to CrashAssessment.ACRReason. Elaborates on

Pre-Impact Stability
Definition: The purpose of this variable is to assess the stability of the vehicle after the critical
event. The stability of the vehicle prior to an avoidance action is not considered except in the
following situation: A vehicle that is out of control (e.g. yawing clockwise) prior to an avoidance
maneuver is coded Other vehicle loss of control only if an avoidance action was taken in
response to an impending danger. Thus, the variable focuses upon this vehicles dynamics after
the critical event.

Crash Configuration
Definition: This variable is used in categorizing the collisions of drivers involved in crashes. A
collision is defined here as the first harmful event in a crash between a vehicle and some object,
accompanied by property damage or human injury. The object may be another vehicle, a person,
an animal, a fixed object, the road surface, or the ground. If the first collision is a rollover, the
impact is with the ground or road surface. The collision may also involve plowing into soft ground,
if severe deceleration results in damage or injury. A road departure without damage or injury is
not defined as a collision. This variable is part of the larger variable Crash Type. The Crash
Type variable is actually broken down into three components: the crash category, the crash
configuration, and the accident type. This variable only deals with the configuration of the crash.

Appendix A: LTCCS Sampling and Analytical Issues
Sample Design
The selection of crashes for the LTCCS was accomplished in two stages, using the infrastructure
of the National Automotive Sampling System (NASS) Crashworthiness Data System (CDS). The
first stage is the selection of geographic areas called primary sampling units (PSUs). The United
States has been divided into 1,195 PSUs where each PSU is comprised on a large city, a large
county, or a group of counties. The PSUs are grouped into 12 categories or strata described by
geographic region (northeast, midwest, south, west) and degree of population (central city, large
county, and group of counties). PSUs were selected for the sample in 1986 based on probabilities
proportional to the number of fatal and injury crashes in that PSU in 1983. The more crashes in a
PSU, the greater the likelihood that PSU would be included in the sample. The four geographic
regions are:
Northeast
New Jersey  Ocean County
New York  Kings County (Brooklyn)
New York  Ulster County
Pennsylvania  Allegheny County (except Pittsburgh)
Pennsylvania  Montgomery County
Pennsylvania  Philadelphia
Midwest
Illinois  Chicago
Indiana  Lake County
Michigan  Genesee County
Michigan  Muskegon County
Michigan  Washtenaw County
Nebraska  Douglas County
South
Alabama  Bibb and Tuscaloosa Counties
Florida  Fort Lauderdale and Hollywood
Maryland  Charles and Prince Georges Counties
North Carolina  Wake County
Tennessee  Knox County
Texas  Dallas
West
Arizona  Gila, Graham, and Greenlee Counties
Arizona  Yuma and La Paz Counties
California  Los Angeles
Colorado  Gilpin and Jefferson Counties
Washington  King County (except Seattle)
Washington  Seattle
In the second stage, researchers were notified of truck crashes within their PSU. To qualify for
the LTCCS, a crash had to involve a large truck and at least one fatality that could be classified
LTCCS Analytical User's Manual Appendix A: LTCCS Sampling and Analytical Issues  509

as K, or at least one injury that could be classified as A or B on the KABCOU scale defined
as:
K = Killed
A = Incapacitating Injury
B= Non-Incapacitating Injury
C= Possible Injury
O=No Injury
U = Unknown
In most PSUs the goal was to research all qualifying crashes. However, due to notification
difficulties the crashes sampled were in reality a subset of the crashes occurring in the PSU. The
difference is accounted for in the sampling weights. Also, researchers sometimes responded to
crashes that didnt qualify for the nationally representative sample. If such cases were
researched, they remain in the LTCCS files for anecdotal analysis with weights of zero (see
Sampling Weights).
Sampling Weights
Each LTCCS case has a value in the variable RATWEIGHT (Ratio Weight). This variable gives
the statistical sampling weight of the case for national representation. RATWEIGHT should be
used as the weighting variable in all statistical analyses.
The LTCCS case weights sum to NHTSAs NASS General Estimates System (GES) estimate of
in-transport large truck crashes of maximum injury severity K, A or B nationwide from April 1,
2001 to December 31, 2003 inclusive. The GES was used because it covers all types of crashes
regardless of vehicle type. The CDS focuses only on those crashes in which at least one
passenger vehicle was towed due to damage.
In each PSU, within-PSU weights were derived as the ratio of qualifying GES cases listed during
the period of the study to qualifying sampled LTCCS cases in the PSU over the entire period of
the study. The resulting weights were then multiplied by the CDS PSU weight (the inverse of the
PSU probability of selection) for the respective CDS PSUs. Use of the GES PSU weights would
not have been valid as PSU weights because the GES has 60 PSUs whereas the truck study was
only performed only in the 24 CDS PSUs.
In a final step, the weights resulting from the above steps were post-stratified to GES national
estimates by PSU region and researched maximum injury severity (see below). This was
conducted by applying to the unadjusted weight a ratio equal to the ratio of the GES estimate of
the number of qualifying crashes to the unadjusted LTCCS estimate of the number of qualifying
crashes by region and researched severity. The 24 CDS PSUs are evenly distributed among four
NASS geographic regions of the United States, so that each region contains six PSUs. The post-
stratification was applied to remove biases that could occur toward higher injury levels due to the
notification process.
Weighted Injury Severity
The LTCCS case weights sum by maximum injury severity to the GES estimates by maximum
injury severity if and only if the following variables are used for maximum severity:
Crash file CRASHRESSevCode
General Vehicle File GVERESSevCode
NonMotorists file ANMRESSevCode
LTCCS Analytical User's Manual Appendix A: LTCCS Sampling and Analytical Issues  510

Explanation
Each LTCCS case contains two different variables assessing the showing the maximum injury
severity that was recorded on the PAR for the case. However, the truck cases were weighted to
the GES estimate of similar cases nationwide. In the GES, coders overrule the PAR severity if
the PAR narrative disagrees with the PAR severity. Therefore, a similar coding procedure was
undertaken for the truck cases. Experienced NASS injury coders reviewed each vehicle narrative
and occupant injury coding for each vehicle in each truck case, and recorded the maximum injury
level by vehicle. The coders also reviewed all non-motorist injuries. If initial reviews were not in
agreement, the case was re-examined until consensus was reached. If no information was
available except the PAR assessment, the PAR assessment was migrated into the researched
assessment.
The results of the researched severity assessment were coded into the variables
GVERESSevCode at the vehicle level and ANMRESSevCode for non-motorists. The crash level
CRASHRESSevCode was derived from GVERESSevCode and ANMRESSevCode by taking the
highest researched severity in a crash in either the GeneralVehicle or NonMotorists file.
Cases of Weight Zero
Of 1070 truck cases in the files, 963 have weights greater than zero. These 963 are the
nationally representative sample of in-transport large truck cases with maximum injury severity K,
A, or B occurring between April 1, 2001 and December 31, 2003. LTCCS cases not belonging to
that universe of cases have weights of zero. Zero-weight cases have not been removed from the
truck database so that may be available for clinical analysis and anecdotal data. However, they
should not be included in analyses for national representation. Note that in any software package
with a weight statement, using the weighted data will result in omission of any cases with weight
zero. Zero-weight cases fall into at least one of the following categories:
Crashes Occurring Before April 1, 2001
These cases are considered pilot cases and do not occur in every PSU. During this time,
procedures were being tested and finalized. Seventy-five cases fall into this category.
Crashes Where Maximum Researched Injury Severity Is Not K, A, Or B
These cases are not part of the universe represented by the weighted cases. These cases
include those where the maximum researched injury severity was C (5 cases), O (11 cases), U (1
case), or where the only non-C/O/U injury was a fatality ruled as occurring prior to the crash
(three cases). To weight these cases to GES cases of the same maximum injury level would
change the universe of the weighted LTCCS, and would also be impractical given their very small
sample sizes.
Crashes Where The Only Involved Large Truck Was Not In Transport
Crashes where the only involved large truck was not in transport (for instance parked on
shoulder) are not part of the universe represented by the weighted cases. Twelve non-pilot
LTCCS cases fall into this category. Their case ID (variable name CASEID) numbers are:
207003882, 333006634, 333006859, 806004774, 806005979, 807005027, 808004521,
811005122, 812004811, 816005021, 817005068 and 821003827.
Analysis Issues
Standard Errors
The LTCCS employed a complex sample design involving stages of sampling. Therefore,
statistical analyses involving variances or standard errors (or procedures that use them, such as
hypothesis testing and confidence intervals) should be conducted using a software product that
can take the sampling stages into account, such as RTIs Survey Data Analysis (SUDAAN). The
nesting variables to use in such an analysis are PSUSTRATA and PSU. The weight variable is
LTCCS Analytical User's Manual Appendix A: LTCCS Sampling and Analytical Issues  511

RATWEIGHT. Using regular SAS procedures will give standard errors that treat the sample as a
simple random sample and are likely to be underestimated.
Time Period
Due to the small sample size, it is strongly recommended that the truck sample be used as a
whole rather than broken down into years, months, weeks, days of the week or time of day.
Estimates or trends based on years, months, weeks, days of the week or time of day will not be
valid.
Injury Severity
Weighted and unweighted counts for maximum injury severity as measured by PAR vs.
researched assessment will not necessarily match. The researched severity assessments 
CRASHRESSevCode, GVERESSevCode and ANMRESSevCode - should be used for any
weighted analysis involving severity. The PAR severity variables (CrashPARSevCode,
GVEPARSevCode, ANMPARSevCode) should not be used for weighted analyses involving
severity.
