The True Cost of Substandard Highway Barriers: A Financial and Safety Analysis
A comprehensive analysis of total cost of ownership for highway barrier systems reveals that substandard installations can cost agencies 3-5x more over a 20-year lifecycle when accounting for crash repairs, liability exposure, DOT audit remediation, and accelerated replacement cycles.
MASH vs NCHRP 350: Understanding Modern Crash Testing Standards and What They Mean for Your Project
With the FHWA mandate requiring MASH-compliant hardware on all new installations and full replacements on the National Highway System, understanding the differences between MASH and its predecessor NCHRP 350 is critical for every DOT engineer and project manager. This guide breaks down test levels, vehicle specifications, evaluation criteria, and the compliance verification process.
High-Tension Cable Barrier Systems: 10 Years of Performance Data and Lessons Learned
Analysis of over 3,200 miles of high-tension cable barrier installations across eight states reveals a 92-97% reduction in cross-median fatalities, with annual maintenance costs averaging $1,850 per mile — making cable barrier the most cost-effective median safety treatment available for divided highways.
Work Zone Safety: Temporary Barrier Selection, Placement, and Management Best Practices
Work zone fatalities have increased 47% over the past decade despite improvements in vehicle safety technology. Properly selected, placed, and maintained temporary barrier systems are the single most effective countermeasure for separating workers from live traffic — yet too many projects rely on channelizing devices that offer zero structural protection.
Bridge Rail Systems: Meeting TL-4 and TL-5 Containment Requirements on Modern Infrastructure
Bridge rail systems operate under fundamentally different engineering constraints than roadside barriers. This whitepaper examines MASH TL-4 and TL-5 containment requirements, concrete and steel bridge rail profiles, approach transitions, deck anchorage design, and retrofit strategies for existing structures.
Post-Installation Inspection and Maintenance of Steel Beam Guardrail: A Field Guide
Steel beam guardrail protects motorists only when it is properly installed and maintained. This field guide covers post-installation inspection checklists, common installation defects, crash damage assessment criteria for repair versus replacement decisions, component-level inspection of W-beam, posts, blockouts, and end terminals, and a practical seasonal maintenance schedule for DOT crews.
Impact Attenuator Selection Guide: Matching Crash Cushion Technology to Site-Specific Hazards
Impact attenuators are the last line of defense at gore areas, bridge piers, toll plazas, and fixed-object hazards. This guide examines MASH test level requirements, redirective vs. non-redirective vs. gating system types, sand barrel arrays, water-filled and steel cartridge technologies, site constraint analysis, and lifecycle cost considerations for crash cushion selection.
Median Barrier Cost-Benefit Analysis: A Decision Framework for State DOT Engineers and Planners
Cross-median crashes represent the most severe collision type on divided highways, with fatality rates 5 to 8 times higher than same-direction crashes. This whitepaper presents a comprehensive cost-benefit framework for median barrier decisions, including AASHTO warrants, crash cost calculations using FHWA values, barrier type comparisons across median widths, terrain-adjusted installation costs, long-term maintenance projections, and HSIP funding strategies.
Wildlife-Vehicle Collision Mitigation: Fencing Design, Crossing Structures, and Corridor Planning
Wildlife-vehicle collisions cause 1 to 2 million crashes per year in the United States, resulting in approximately 200 human fatalities, 26,000 injuries, and over $8 billion in economic losses annually. This whitepaper examines the integrated approach to WVC mitigation, including exclusion fence design, wildlife crossing structures, escape mechanisms, monitoring and effectiveness data, and multi-agency corridor planning strategies.
