Improved highway safety analysis saves lives with better data and methods.
The article discusses how to improve highway safety analysis by ensuring accurate and complete data availability. Linking data from various sources can enhance safety analysis. Coordinated data collection helps avoid duplication. Trained professionals should assess countermeasure effectiveness, not operations personnel. Experimental designs are crucial, and simple before/after evaluations have limitations. Empirical Bayesian statistics, incremental effectiveness, and interpretation of analysis results are important for evaluating highway safety.
