Mobile roadside construction is one of the most hazardous industries, where workers are exposed to constant dangers from moving traffic, heavy equipment, and challenging environmental conditions. Despite decades of safety improvements, construction zones remain high-risk areas, with workers frequently being injured or killed in preventable incidents. As infrastructure demands increase globally, the safety of these workers has become a critical issue that requires innovative solutions.

To address this challenge, Metrolla has introduced Lightship, an advanced safety product that leverages state-of-the-art LiDAR technology to detect imminent hazards in real time. By combining predictive collision warnings, enhanced visibility, and wearable alerts, Lightship empowers workers to proactively avoid danger, setting a new standard for safety in dynamic roadside environments.

Understanding the Risks in Roadside Construction

Statistics on Worker Injuries and Fatalities

Roadside construction sites are among the most dangerous workplaces. According to the U.S. Federal Highway Administration (FHWA), over 800 fatalities occur annually in construction zones, with 50% of these involving workers struck by vehicles. Globally, road construction accidents account for thousands of injuries and deaths each year. In 2021, work zone fatalities reached a 16-year high, underscoring the urgent need for better safety measures.

In addition to fatalities, non-fatal injuries also pose a significant challenge. Workers often face long-term physical and psychological consequences from accidents, while companies bear the costs of medical expenses, lawsuits, and project delays. These incidents result in billions of dollars in annual economic losses worldwide.

Common Causes of Accidents

Several factors contribute to the high risk of accidents in roadside construction zones. Understanding these causes is key to implementing effective safety solutions:

• Distracted Driving: With smartphones, in-car entertainment, and navigation systems, driver attentiveness has declined significantly in recent years. This distraction is a leading cause of construction zone accidents.
• Low Visibility: Nighttime work and adverse weather conditions, such as fog or rain, often reduce drivers’ ability to see workers and equipment in time to avoid collisions.
• Unpredictable Traffic: Vehicles frequently speed through construction zones, ignore lane markings, or fail to heed warning signs, creating dangerous conditions for workers.
• Worker Mobility: Unlike stationary equipment, workers often move between different locations, increasing their exposure to moving vehicles.

The Role of Collision Attenuators

Collision attenuators, also known as crash cushions, are a critical component of roadside safety. These devices are designed to absorb the force of an impact, reducing the severity of injuries for both workers and vehicle occupants. In mobile applications, attenuators are mounted on specialized trucks, allowing them to move with workers as they perform tasks across various locations.

While attenuators provide essential protection, they are inherently reactive, mitigating the consequences of an impact rather than preventing it. This makes them an important but incomplete solution. Lightship complements these devices by introducing a proactive element to safety, providing early warnings to both drivers and workers to avoid collisions altogether.

Traditional Safety Measures: Why They Are No Longer Sufficient

High-Visibility Clothing and Signage

For decades, high-visibility vests, reflective signs, and traffic cones have been the primary tools for roadside worker safety. These measures are designed to increase awareness among drivers, helping them identify work zones and spot workers in their path. However, these methods rely heavily on drivers' attentiveness, which is becoming increasingly unreliable due to distractions like smartphones and in-car technology.

Additionally, these passive safety measures are often less effective in low-visibility conditions, such as during nighttime operations or adverse weather. Despite their widespread use, high-visibility clothing and signage alone are not sufficient to prevent accidents in modern work zones.

Collision Attenuators: Effective but Limited

Collision attenuators are indispensable for protecting both workers and drivers in the event of an accident. These systems absorb the energy of a collision, significantly reducing the risk of severe injuries or fatalities. In mobile setups, attenuators are mounted on vehicles that accompany workers, offering continuous protection as the work zone shifts.

However, attenuators are primarily designed for stationary or near-stationary impacts, and their effectiveness diminishes when dealing with high-speed or unpredictable traffic patterns. Furthermore, they do not address the root causes of accidents, such as distracted driving or low visibility. This highlights the need for complementary technologies like Lightship, which proactively detect and mitigate risks.

The Case for Real-Time Hazard Detection

As construction projects become more complex and traffic volumes continue to rise, the limitations of traditional safety measures have become increasingly apparent. Reactive solutions, while valuable, are no longer enough to ensure the safety of roadside workers. Advanced systems that provide real-time hazard detection and early warnings are essential to addressing the root causes of accidents and protecting workers in dynamic environments.

Metrolla’s Lightship bridges this gap by integrating LiDAR technology with a suite of alert mechanisms to proactively safeguard workers. By detecting potential collisions before they occur, Lightship enables workers to respond in time, preventing accidents rather than merely mitigating their impact.

Introducing Metrolla’s Lightship: A New Era in Safety

What is LiDAR and Why Is It Better Than Video?

Understanding LiDAR: Light Detection and Ranging

LiDAR, or Light Detection and Ranging, is a remote sensing technology that uses laser pulses to measure distances. By emitting thousands of laser pulses per second and analyzing the reflected light, LiDAR creates highly accurate 3D maps of the surrounding environment. This level of detail enables precise detection and tracking of objects, even in complex or dynamic settings.

LiDAR vs. Video Systems

While traditional video systems rely on cameras to capture 2D images, they have significant limitations when it comes to roadside safety:

• Depth Perception: Video systems struggle to accurately determine the distance and speed of approaching vehicles, especially in low-light conditions. LiDAR, on the other hand, provides precise 3D data that eliminates guesswork.
• Environmental Conditions: Fog, rain, and glare can obstruct video systems, rendering them ineffective. LiDAR operates reliably in all weather conditions, ensuring consistent performance.
• Real-Time Analysis: LiDAR processes data faster and more accurately than video, enabling real-time hazard detection and predictive analytics.

These advantages make LiDAR the ideal choice for dynamic safety applications like roadside construction, where accuracy and reliability are paramount.
