Central Reserve / Median Safety Barriers

This report explores the selection of central reserve and median safety barriers, challenging the common perception that concrete barriers are always the safest and most effective solution. Drawing on historical guidance, industry studies, current standards, and real-world performance data, it examines the strengths and limitations of both steel and concrete vehicle restraint systems.

The report highlights how modern high-containment steel barriers can deliver comparable safety performance to concrete systems while offering potential advantages in accessibility, maintainability, flexibility, installation, and carbon reduction. It concludes that barrier selection should be evidence-based and driven by project-specific requirements, rather than assumptions about material type alone.

Read the report to discover the facts behind central reserve barrier selection and why a performance-led approach is key to delivering safer, more efficient road infrastructure
