Which of the following are field activities that can be used to diagnose safety issues on a roadway?

Both a Roadway Safety Audit and a Traffic Conflict Study are essential field activities used to diagnose safety issues on a roadway.

A Roadway Safety Audit involves a comprehensive review of a roadway or intersection to identify potential safety issues based on engineering and safety principles. It encompasses evaluating the design, operational performance, and safety of the road to propose measures that could enhance safety for all users.

A Traffic Conflict Study, on the other hand, assesses the interactions and potential conflicts between different road users, such as vehicles, pedestrians, and cyclists. By observing and analyzing these interactions, safety professionals can identify critical areas where improvements or interventions are needed to reduce the likelihood of accidents.

Using both methods provides a robust approach to understanding and diagnosing safety issues, allowing for a more thorough and effective response to enhancing roadway safety. This combination emphasizes the importance of an integrated approach in addressing safety problems, leading to well-informed decision-making and ultimately safer roadways.
