DEVELOPMENT OF A METHODOLOGY FOR ACCIDENT CAUSATION RESEARCH

The objective of this study was to fully develop and apply a methodology to study accident causation, which was outlined in a previous study. "Causal" factors are those pre-crash factors, which are statistically related to the accident rate for specific types of accidents, in specific pre-crash situations. To calculate accident rates, exposure measures matched to the pre-crash situations are needed. Data collection techniques to collect certain basic data by roadside observations were developed. A data collection design was developed, indicating when and where to collect data in Ulster and Schenectady Counties, New York. Data were collected, and exposure estimates for several pre-crash situations derived. Using police accident reports, accident rates were calculated for these pre-crash situations. The relations of these rates to various pre-crash factors and their interactions were studied. The general methodology is described in a separate "Manual for Accident Causation Research."
