The goal of the Federal Highway Administration (FHWA) Expert Systems for Crash Data Collection Program was to use expert system technology to improve the accuracy and consistency of police-reported data. The program included the development and evaluation of three systems: (1) Seat Belt Use 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 were evaluated dring 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 system.
