NHTSA’s State Data SystemExpansion Effort
A collection of crash data received directly from the 21 participating states.
The data consists of all state-reported crashes. Census data received annually.
The primary use of state data is for specialized internal studies.
SDS
SDS
State data are converted into a standard SAS format—the data structure is similar to FARS.
State variable attributes are retained. No recoding or standardization of attributes is done in SDS.
State annual Traffic Facts are used to ensure that data is processed correctly.
Data files are sanitized:All personal identifiers are removed during
creation of the SAS data files. VINs are truncated to 12 characters to protect
vehicle owners.General information may be retained, for
example:• State of Vehicle Registration• Driver Zip Code
Data Confidentiality
Internet access to state raw data files is strictly prohibited.
Internet access to NHTSA’s SAS data files is strictly prohibited.
If state chooses to allow its crash statistics to be published, statistical summary information may be posted on the Internet.
Internet Access
Rollover Analysis:Firestone/Ford Explorer rollover analysis. Implementation of rollover ratings in NHTSA’s New Car
Assessment Program. Supports NHTSA’s Office of Defects
Investigation. Useful for evaluating state voluntary
implementation of MMUCC. Useful for linkage to injury outcome data in
CODES.
How SDS Data are Used
Useful for evaluating the effectiveness of vehicle safety equipment and safety campaigns:Safety belts.Anti-lock braking systems.High mounted stop lamps and daytime running
lights.Alcohol awareness campaign.Moving young children to the back seat.
How SDS Data are Used
Crash Data Report: 1990-1999 available for downloading. Includes descriptive stats in tables and charts.
New York—Concerns over losing data sales revenue, data publication pre-emption, data misinterpretation, and lack of resources to reconcile discrepancies between NHTSA and state totals.
Rhode Island—Concern over data misinterpretation and incomplete nature of RI data files.
Vermont—"No compelling reason to join".
Two Levels of SDS Membership
1. State permits dissemination of state-specific summary information via publications and other methods.
2. State prohibits dissemination of state-specific summary information. For research purposes, the data is aggregated, making it impossible to determine the state’s contribution to the analysis pool.
US DOT researchers outside of NHTSA do not have access to SDS data files unless written permission is obtained from state.
During the approval process, state is advised of the specific intended use of state data by the requesting US DOT modality.
US DOT Data Access Policy
Public access to SDS data files is prohibited unless the researcher obtains written permission from state.
During the approval process, state is advised of the specific intended use of state data by the researcher.
Public Data Access Policy
Where Do We Go From Here?
Are the current SDS marketing materials sufficient for state solicitations?
Should we continue SDS presentations at TRCC meetings?
What additional assistance is needed by Regional staff to help with Dr. Runge’s data initiative?
MODEL MINIMUM UNIFORM CRASH CRITERIA
MMUCC 2nd Edition (2003), published June 2003.
Standardizes state crash data to generate the comprehensive information needed to improve highway safety within each state and nationally.
Facilitates inter- and intra state comparisons.
MMUCC FORMAT
Data element name, definition, set of attribute values.
Based on existing standards (ANSI D16.1, ANSI D20.1, FARS, NASS and FMCSA).
Data elements collected at scene, derived, or obtained through linkage.
Voluntary implementation. No MMUCC police!!
REPORTING THRESHOLD
Death, personal injury or property damage of $1,000 or more.
All involved persons (injured and non-injured).
Consistent and uniformly implemented statewide.
BENEFITS OF MMUCC
Facilitates inter- and intra state comparisons.
Standardizes population-based data to identify national trends and issues.
MMUCC incorporated into TraCS software Next revision in 2007; publication in 2008Assistance to be available:
web-based trainingmarketing materialsroll call video for law enforcementsurveys of state implementationbest practices guides, etc.
NEXT STEPS
29 CODES States funded. Fifty percent or more of the states in nine
of the 10 NHTSA Regions.41% of CODES states also part of
SDS.Goal is to add all CODES states.
CRASH OUTCOME DATA EVALUATION SYSTEM
PURPOSE OF CODES
Expands crash data so that all components of highway safety can be evaluated in terms of death, injury, injury severity and total inpatient charges.
CODES MODEL
Links injury outcome to:
specific person, vehicle and event characteristics for all persons, injured or uninjured, involved in crashes statewide.
CRASH DATA LINKED TO:
Injury Data• EMS, ED, Inpatient, Trauma Registry• Death Certificate, Medical Examiner
Insurance Claims (health or vehicle) Other Traffic Records
