ANALYSIS OF RELIABILITY OF ACCIDENT INFORMATION OBTAINED FROM OFF-THE-SCENE SOURCES, PT. 1

THE PRIMARY OBJECTIVE WAS TO TEST THE RELIABILITY OF RETRIEVING (OR DERIVING) SPECIFIC DATA ITEMS FROM EXISTING OFF-THE-SCENE SOURCES THROUGH THE USE OF CORE DATA ITEMS RECORDED ON-SCENE. A RELATED OBJECTIVE WAS TO ASSESS THE STATISTICAL SIGNIFICANCE OF ANY DIFFERENCE WHICH MIGHT OCCUR BETWEEN OFF-THE-SCENE AND ON-SCENE INFORMATION. THE RESULTS SHOW THAT RELIABLE OFF-SCENE SOURCES EXIST FOR A NUMBER OF ACCIDENT INVESTIGATION PROCEDURES. AREAS OF FUTURE RESEARCH INCLUDE EXTENSIONS OF RELIABILITY ANALYSIS TO OTHER OFF-SCENE SOURCES AND DATA ITEMS, AND A COST ANALYSIS OF THE ON-SCENE INVESTIGATION PROCESS. THE RESULTS WOULD PROVIDE ESSENTIAL INPUTS TO A COST-EFFECTIVENESS COMPARISON OF THE PRESENT AND PROPOSED ALTERNATIVE METHOD OF ACCIDENT DATA COLLECTION. /HSL/
