Expert Systems for Crash Data Collection: Final Report
This report provides information on the development and testing of expert systems to improve the completeness, consistency, and quality of police–reported crash data. The systems were developed with input from police officers, a vehicle safety engineer, a crash reconstructionist, a crash investigation trainer, and a highway safety analyst. State agencies that have police officers using pen–based computers to collect State–reported crash data can integrate the expert systems with their computer software.

There is a demand by the highway safety community for better quality crash data to meet a variety of needs. The goal of the Federal Highway Administration
(FHWA) Expert Systems for Crash Data Collection Program was to use expert systems technology to improve the accuracy and consistency of police–
reported data. The program included the development and evaluation of three expert systems: (1) Seat Belt Use of Derivation; (2) Vehicle Damage Rating,
including Extent of Deformation; and (3) Roadside Barrier Problem Identification.
Police officers used pen–based computers, containing the expert systems, to collect on–scene crash data. Embedded in the expert systems are
data collection knowledge derived from experts in crash data collection and analysis. The expert systems use this knowledge to intelligently select the
data to collect and assign values to elements. This knowledge is also included in on–line help screens that aid the officer in accurately identifying
the physical characteristics of the crash scene.
The expert systems were evaluated during two field tests. The field test results showed that the expert systems: (1) were well accepted by the officers,
(2) were validated by experts in the expert system domain areas, and (3) the officers collected data on an average of approximately 2 minutes per expert
