IMPROVING THE RESEARCHER'S EFFECTIVENESS: HOW READABILITY AND INFORMATION FACTORS AFFECT COMPUTERIZED ACCIDENT DATA ANALYSIS

THE RESULTS OF TWO NIGHTTIME ROADSIDE SURVEYS MEASURING BLOOD ALCOHOL CONCENTRATIONS (BAC) IN DRIVERS IN MECKLENBURG COUNTY, NORTH CAROLINA, AND WASHTENAW COUNTY, MICHIGAN ARE COMPARED. THE PERCENTAGES OF DRIVERS AT EACH BAC LEVEL WERE SIMILAR IN BOTH SURVEYS. BOTH STUDIES INDICATED THAT DIVORCED AND SEPARATED DRIVERS WERE MORE LIKELY TO HAVE BEEN DRINKING; THAT THE PERCENTAGE OF DRINKING DRIVERS WAS HIGHEST DURING THE EARLY MORNING HOURS; AND THAT, WITHIN THE NIGHTTIME DRIVING POPULATION, DRINKING WAS NOT A FUNCTION OF EDUCATIONAL LEVEL. THE MECKLENBURG STUDY SHOWED A LARGER DIFFERENCE BETWEEN WEEKEND AND WEEKDAY DRINKING AND DRIVING THAN DID WASHTENAW COUNTY.
