Explanation

Roadway safety issues are addressed through work zone protection (C) and vehicle counting and classification (E). Work zone protection directly reduces hazards in active construction or maintenance areas by deploying barriers, signage, and traffic control measures that shield workers and drivers alike. Vehicle counting and classification identifies traffic composition - including heavy or oversized vehicles - enabling authorities to detect safety-critical conditions like weight-limit violations or dangerous congestion patterns before incidents occur.

Why the distractors are wrong:

• A (Dynamic message sign automation) - Automating signs is an operational efficiency measure; the signs themselves aid awareness, but automation of their management doesn't directly resolve a safety issue.
• B (Vehicle weight assessment) - Weight monitoring supports infrastructure protection and enforcement, but it is a subset of vehicle classification rather than a standalone safety-addressing method.
• D (Workflow automation and enforcement) - This is a broad administrative concept with no specific roadway safety mechanism tied to it.

Memory tip: Think "Construction zones + Counting cars = Core safety." The two correct answers both involve direct observation or control of the physical roadway environment, while the wrong answers are about automation, administration, or narrower data collection tasks.
