National Motor Vehicle Crash Causation Survey (NMVCCS)

January 1, 2005 - December 31, 2007 Data

Version 29Oct08

Introduction

This code book documents data sets describing a sample of motor

vehicle crashes that occurred in the USA during calendar years

2005-2007. These sets represent the National Motor Vehicle Crash

Causation Survey distribution file dated October 29, 2008. The

data sets were generated by the Transportation Data Center at the

University of Michigan's Transportation Research Institute from

data collected by the National Center for Statistics and Analysis

(NCSA) of the National Highway Traffic Safety Administration

(NHTSA). The cooperation of NHTSA is gratefully acknowledged.

The 2005-2007 NMVCCS data represents a statistical sample of

motor-vehicle crashes whose collection methodology was designed to

assist in studies directed toward a determination of crash

causation. A primary requirement of the study was that NHTSA

investigators be on the scene of the crash.

Primary program requirements include:

The crash must have resulted in a harmful event associated with a vehicle in transport on a trafficway.

EMS must have been dispatched to the crash scene.

At least one of the first three crash-involved vehicles must be present at the crash scene when the NMVCCS researcher arrives.

The police must be present at the scene of the crash when the NMVCCS researcher arrives.

One of the first three vehicles involved in the crash was a light passenger vehicle that was towed.

A completed police accident report for this crash must be available.

NMVCCSD 2005-2007 Introduction

Version 29Oct08 ii

The data are a sample of 2005-2007 motor vehicle crashes for

which candidate crashes were chosen with varying probabilities

according to a scheme detailed in the Analytical User’s Manual.1

The Field Coding Manual2 provides detailed information on the

interpretation and coding protocol for each information element.

The relational data set supplied by NCSA contains twenty three

separate relational files describing each accident. A large

number of flat files can obviously be generated from this wealth

of complex relations. Users with a need for joins not represented

by the system data sets are encouraged to contact the Data Center.

Vehicle and Occupant data sets were generated by relational

joins of the corresponding record types. Injury data was not

collected during this study. Since a given vehicle is not, in

general, represented in all file relations, filler records are

substituted whenever one of the records is missing.

The characteristics of the system data sets that have been

developed are presented in the table below.

While every effort has been made to provide accurate, reliable

data, inconsistencies may arise from the source data or from the

reformatting procedures used. Consequently, the Data Center

cannot guarantee the accuracy of the data but will try to correct

any discrepancies that are found. Please notify the Center of any

errors or data inconsistencies that are uncovered, as well as any

suggestions or comments that you may have concerning the code book

by calling (734) 763-3230 or by emailing [email protected].

Flip-over 3Selected when the vehicle is rotated about its longitudinal axis by a ramp-like object may be in a yaw when it comes in contact with the ramp-like object. For example, if the vehicle traveling forward climbs the down turned end of a guardrail and rolls over about its longitudinal axis, use this code. To use this, the vehicle's roll need not begin on the ramp-like structure or object, For example, if the vehicle transverses the turned-down end of a guardrail, continues along the level portion, then rolls back toward the side of the guardrail from which it came, use this code.

Screen Name: Type of Rollover Initiation

General Vehicle

VEHICLE.ROLL_INIT_TYPEField Variable:

Turn-over (specify) :Selected when centrifugal forces from a sharply turning or rotating vehicle produce a rollover when resisted by normal surface friction. This type of rollover is more likely to occur in vehicles with a higher center of gravity than most passenger vehicles. The surface type includes pavement surfaces plus gravel, grass, dirt, etc. The distinction between Turn-over and Trip-over is that no furrowing, gouging, etc. occurs to the surface at the point of trip. In addition, see remarks for Fall-over below. When turnover is selected, the justification must be entered.This attribute does not include cargo shift; code cargo shift under cargo shift.

Turn Over:Centrifugal forces froma sharply turning or rotatingvehicle produce a rollovermoment when resistedby surface friction.

VEHICLE.ROLL_INIT_TYPEField Variable:

Climb-overSelected when a vehicle climbs up and over a fixed object such as a barrier or guardrail. The object should be high enough to lift the vehicle completely off the ground (i.e., the height should exceed the radius of the vehicle's largest diameter wheel). The vehicle must roll to the opposite side from which it approached the object.

Screen Name: Type of Rollover Initiation

General Vehicle

VEHICLE.ROLL_INIT_TYPEField Variable:

Fall-overSelected when the surface the vehicle is traversing slopes downward in the direction of movement of the vehicle's center-of-gravity such that the vehicle's center of gravity becomes outboard of its wheels. The distinction between this and Turn-over above involves the negative slope of the traversed surface. If the rotation and/or the surface friction causes the trip, then use Turn-over, however, if the slope is so negative that a line straight downward through the vehicle's center-of-gravity (as shown in the illustration ) would fall outside the vehicle's track, then use this attribute. For example, if a vehicle goes off the road and encounters a substantial surface drop off because of the elevated nature of the road in relation to its environment (e.g., cliff, ditch, etc.), then use this attribute.

Screen Name: Type of Rollover Initiation

General Vehicle

VEHICLE.ROLL_INIT_TYPEField Variable:

Bounce-overSelected when a vehicle deflects off of a fixed object (such as a guardrail, barrier, tree, or pole) or a not-in-transport vehicle such that the vehicle's rotation causes it to overturn. The deflection momentum contributes to a rollover. To use this attribute, the rollover must occur in close proximity to the object from which it deflected. For example, if a vehicle strikes a center median barrier and rotates across two traffic lanes prior to the vehicle rolling over, then Trip-over or Turn-over would apply.

Bounce-Over:Any case where the vehiclerebounds off a fixed object(such as a guardrail) and overturns as a consequence.

Collision with another vehicleSelected when an impact with another vehicle causes the rollover. The rollover must be the immediate result of the impact between the vehicles (e.g., intersection crashes where a vehicle is struck in the side and the momentum of the struck vehicle results in the rollover, or offset end-to-end type crashes when one vehicle will vault over the tapered end of another vehicle resulting in a rollover). Otherwise use attributes above. For example, if a vehicle is struck in the side and the vehicle rotates and does not produce any wheel/rim gouges or furrows in the surface nor encounters any prominent raised objects (e.g., a high curb) and overturns in close proximity to the point of impact, then use this attribute.

8

Other rollover initiation type (specify) :Selected when this vehicle's rollover initiation type cannot be described above. Whenever this is used, the researcher is required to specify the type of rollover which occurred.

9

Cargo shiftThis attribute is used only when there is definitive evidencs that cargo shift is the predominant cause of the rollover. The cargo shift must occur prior to the rollover event. Coding of this attribute requires very careful questioning of the driver or occupants of the rollover vehicle.

10

End-over-endSelected when the rollover is mainly end-over-end. This attribute is used when a rollover is a combination of a side-to-side and end-over-end roll and it cannot be determined which type of rollover is most prevalent.This attribute will be automatically entered in the electronic system when the "Direction of initial roll" is end-over-end.

11

Unknown rollover initiation typeSelected when the type of rollover initiation is unknown.

Sideswipe/Angle: Straight Ahead on Left

Crash Configuration: Sideswipe/Angle

The two vehicles are involved in an impact involving the side of one or both vehicles.

The following four codes, "44" (Sideswipe/Angle, straight ahead on left), "45" (Sideswipe/Angle, straight ahead on left/right), "46" (Sideswipe/Angle, changing lanes to the right), "47" (Sideswipe/Angle, changing lanes to the left), identify relative vehicle positions (left versus right) and lane of travel intentions (straight ahead versus changing lanes). From these four codes, four combinations are permitted. They are:

1. "44" and "45" 2. "46" and "45" 3. "45" and "47"4. "46" and "47".

When used in combination, these codes refer to a sideswipe or angle collision which involved a vehicle to the left of a vehicle to the right where:

1) 1. neither vehicle (codes "44" and "45") intended to change its lane;2) 2. the vehicle on the left (code "46") was changing lanes to the right, and the vehicle on the right (code "45") was not intending to change its lane;3) 3. the vehicle on the left (code "45") was not intending to change its lane, and the vehicle on the right (code "47") was changing lanes to the left; and 4) 4. the vehicle on the left (code "46") was changing lanes to the right, and the vehicle on the right (code "47") was changing lanes to the left. In addition, when:

1) 1. the right sides of the two vehicles impact following a 180 degree rotation of the vehicle on the right, or 2) 2. the left sides of the two vehicles impact following a 180 degree rotation of the vehicle on the left.

Select the appropriate combination depending upon:

- their positions (i.e., left versus right) and - the intended lane of travel (straight ahead versus changing lanes) of their drivers.
