Which method is often used for prioritizing safety improvements on roadways?

• A. Cost-benefit analysis
• B. Performance-based measures
• C. Network screening method
• D. Empirical Bayes method

Answer: (C)

The network screening method is a systematic approach used to prioritize safety improvements on roadways by identifying locations with a higher likelihood of crashes or incidents. This method combines historical crash data with specifics of the roadway environment to determine which locations exhibit unsafe conditions, thus enabling targeted interventions. By analyzing various parameters like traffic volume, road geometry, and past accident records, the network screening method helps identify high-risk areas that warrant immediate attention. This prioritization is essential for effective allocation of resources, ensuring that safety measures are implemented where they will have the greatest impact on reducing accidents. This method is advantageous as it provides a clear and focused framework for decision-making, often leading to more efficient and effective safety improvements compared to general approaches that may not specifically target the most dangerous locations.
