Boosting Work Zone Safety with AFADs: Smart, Efficient, and Protective

Work zones are some of the most dangerous environments for both drivers and road workers. Every year, thousands of crashes occur in construction zones, with distracted driving and limited visibility often to blame. That’s why agencies across the country are turning to Automated Flagger Assistance Devices (AFADs) — an innovation that combines technology, safety, and efficiency.

At Transportation Solutions & Lighting (TS&L), we provide state-of-the-art portable traffic signals and AFAD systems designed to protect workers, reduce risks, and keep traffic flowing smoothly.

What Are AFADs?

AFADs (Automated Flagger Assistance Devices) are portable, remotely operated traffic control systems designed to take human flaggers out of harm’s way. Instead of standing in an active traffic lane with a STOP/SLOW paddle, a trained flagger can operate the AFAD remotely, often from a safe location inside a work truck or behind a barrier.

There are two common types of AFADs:

• STOP/SLOW Paddle AFADs – These use a motorized STOP/SLOW sign, mounted on a trailer or cart, that can be controlled remotely.
• Red/Yellow Lens AFADs with Gate Arm – These systems look and operate like a small traffic signal. A red lens and gate arm require vehicles to stop, while a yellow flashing signal warns drivers of upcoming lane closures.

Both types are fully recognized in the Manual on Uniform Traffic Control Devices (MUTCD) and are increasingly being adopted by DOTs and contractors nationwide.

Why AFADs Matter for Work Zone Safety

AFADs aren’t just about convenience — they save lives.

• Protect Workers – By removing flaggers from live traffic, AFADs reduce the chances of flaggers being struck by vehicles.
• Increase Driver Compliance – Studies have shown that drivers are more likely to obey AFAD signals than traditional flagger paddles.
• Reduce Speeds – Research from Missouri DOT found that vehicles approached AFAD-controlled work zones at lower speeds than zones with human flaggers.
• 24/7 Reliability – Solar-powered AFADs can run continuously with minimal maintenance.

At a time when roadway fatalities and work zone crashes are rising, AFADs provide a much-needed layer of protection and consistency.

Regulatory Standards and Best Practices

AFADs are covered under MUTCD Section 6E.04 and must meet specific requirements for deployment. Here are key points:

• Crashworthiness – All AFAD units must comply with NCHRP 350 / AASHTO crash standards.
• Use Case – AFADs are intended for single-lane, two-way traffic control on short to intermediate duration projects (typically up to three days).
• Operator Control – AFADs must always be controlled by a trained human flagger, even when automated. Remote operation does not eliminate the need for trained personnel.
• Traffic Volume Considerations – Many states allow AFADs on roadways with 8,000 vehicles per day or fewer, though some DOTs extend this threshold.
• Placement – AFADs must be positioned in accordance with MUTCD spacing, taper length, and sign placement standards.
  ‍

In short: AFADs are safe, compliant, and effective — but they must be deployed correctly.

Benefits of AFADs for Contractors and Agencies

1. Enhanced Safety

The number one reason to use AFADs is worker safety. Instead of standing in traffic, your crew can control the system from a safe location.

2. Cost Savings

By reducing the number of on-site flaggers required, AFADs can lower labor costs — while still meeting safety standards.

3. Improved Traffic Flow

Unlike human flaggers, AFADs provide consistent, predictable signaling to drivers. That means less confusion, smoother traffic, and fewer delays.

4. Flexibility

Modern AFADs are solar-powered and trailer-mounted, allowing for quick setup, relocation, and 24/7 operation.

5. Public Trust

When drivers see high-visibility AFADs with LED lights, gate arms, and flashing signals, compliance improves. This directly reduces the chance of crashes in work zones.

AFAD Use Cases in the Southeast

Here in the Southeast, AFADs are increasingly deployed for:

• Bridge maintenance projects on two-lane rural highways.
• Utility work requiring short-term lane closures.
• Emergency repairs following storms or hurricanes.
• Haul road intersections near construction sites.

For DOTs, counties, and contractors across Florida, Georgia, Alabama, Tennessee, and beyond, AFADs are proving to be one of the most effective tools for balancing safety and efficiency.
