TOWARD IMPROVED HIGHWAY SAFETY ANALYSIS

This article outlines some of the major obstacles in current practice to improved highway safety analysis, and suggests methods for improvement. The ready availability of accurate and complete data is of paramount importance to improved highway safety analysis. Safety analysis uses data from a variety of sources and file linkage of these data allows opportunity for improved highway safety analysis. Coordinated data collection avoids duplication. Problems with safety information is considered. It is noted that trained professionals should determine countermeasure effectiveness instead of operations personnel. Experimental designs, and the dangers inherent in simple before/after evaluations are discussed. Empirical Bayesian statistics, incremental effectiveness, interpretation of analysis, and applicability of evaluation results are also discussed.
