Truck-mounted attenuators (TMAs) are especially important safety gear shielding workers and drivers in roadwork areas on high-speed Texas freeways. Effective operation of these devices depends on correct deployment. These seven excellent practices will help ensure proper usage and enhance road safety across the state via our TMA Best Practices on Texas Freeways.
TMA Best Practices on Texas Freeways
1. Thorough Site Evaluations
Examining the work zone carefully comes first before TMAs. To choose the suitable TMA model and placement, balance traffic volume, speed restrictions, and lane designs. Texas freeways range in traffic from rural paths with faster speeds to urban congestion; each situation requires a tailored approach. High-traffic cities like Houston or Dallas could need multiple TMAs for maximum safety, while rural locations may allow for longer buffer zones.
2. Best TMA Positioning
TMAs cannot be effective without proper placement. TMAs should be positioned far enough from the construction zone to absorb the full impact of a potential crash. On Texas freeways, where speed limits often reach 75 mph or more, TMAs should generally be located at least 150–200 feet ahead of the work zone. This buffer zone slows any stray vehicles before reaching workers. Always follow the Texas Department of Transportation (TxDOT) guidelines for placement and spacing.
3. Confirm Certified Operators
TMAs should be operated exclusively by certified and competent staff. Operators should be familiar with the equipment, including its proper deployment and maintenance. In Texas, where major infrastructure projects are frequent, ensuring every operator meets TxDOT training standards is essential. Operators must be able to quickly reposition TMAs in response to changing traffic or work zone conditions.
4. Customize for High-Speed Freeways
Many Texas freeways, especially in rural regions, feature high-speed limits. TMAs used on these highways must be rated for higher-speed crash impacts. Different crash ratings exist for TMAs, and using a unit designed for lower-speed urban roads on highways like I-10 or I-20 could result in suboptimal performance. Always verify the TMA’s crash rating to ensure it aligns with the freeway’s speed limits.
5. Efficient Inspection and Maintenance
Routine maintenance and inspections are essential for ensuring TMAs function at their best. Texas’s harsh weather—extreme heat, heavy rain, and dust storms—can wear down equipment over time. Regularly check for physical damage, hydraulic issues, or alignment problems. After any impact, thoroughly inspect the TMA before redeploying it to ensure it remains effective in the event of another crash.
6. Insert Clear Signs and Lighting
While TMAs are crucial for impact prevention, they work best when paired with clear signage and lighting. Use advance warning signs far ahead of the work zone on Texas freeways to alert drivers to upcoming roadwork. Ensure the TMA includes reflective elements and high-visibility lights for nighttime or adverse weather conditions. Clear visibility significantly reduces accident risks.
7: Adhere to Texas DOT Policies
TMAs must be used in compliance with TxDOT policies to ensure safety and legal protection. Texas regulates TMA deployment, installation, and maintenance. Non-compliance may lead to fines or safety hazards. TxDOT guidelines often specify buffer zone distances, required signage, and proper deployment for different road types. Staying updated with the latest TxDOT policies ensures effective and compliant TMA usage.
