The Power of a Layered Approach: Reducing Roadside Injuries by 80%

Learn how a layered safety approach combining TMAs, traffic systems, and the Metrolla Lightship Proximity Alert System delivers an 80% reduction in roadside work zone injuries and fatalities.

Roadside work zones remain among the most dangerous environments for workers. The inherent risks of operating near moving traffic and heavy machinery demand comprehensive safety solutions. While traditional measures like truck-mounted attenuators (TMAs), traffic lights, and digital signs address specific risks, new technologies like the Metrolla Lightship Proximity Alert System are transforming worksite safety, delivering an 80% reduction in injuries and fatalities.

Understanding the Layered Approach

The layered approach to roadside safety combines multiple systems to address distinct aspects of work zone risks. Each layer plays a vital role:

Truck-Mounted Attenuators (TMAs): Reduce crash severity by absorbing impacts.
Traffic Lights and Signs: Improve driver awareness and compliance.
Proximity Alerts: Provide real-time hazard detection, addressing dynamic risks.

When combined, these systems deliver significantly better outcomes than individual measures.

Year-Over-Year Trends in Work Zone Safety

Data from the Federal Highway Administration (FHWA) highlights troubling trends in roadside injuries and fatalities:

Year	Fatalities	Year-Over-Year Change	Key Notes
2018	754	Baseline	Increased traffic density and infrastructure projects.
2019	842	+11.7%	Growth in construction activity.
2020	863	+2.5%	Reduced traffic, but higher crash severity due to speeding.
2021	774	-10.3%	Improved safety protocols contributed to reductions.
2022	891	+15.1%	Post-pandemic rebound in construction activity.

These statistics emphasize the need for advanced safety systems that can adapt to changing conditions in work zones.

The Role of the Metrolla Lightship

The Metrolla Lightship Proximity Alert System addresses worker-specific risks by focusing on near-misses and hazardous proximity. Key features include:

Real-Time Alerts: Provides workers with ~6 seconds to react to potential hazards.
Lidar Detection: Tracks objects in Cartesian space for precise hazard identification.
Local Data Logging: Allows on-site analysis for optimizing worksite safety layouts.
Rugged Design: Weather-resistant and built for demanding environments.

Proven Effectiveness of a Layered Approach

By combining TMAs, lights, digital signs, and proximity alerts, the layered approach reduces residual risks that individual measures cannot fully address. This synergy leads to an 80% reduction in injuries and fatalities.

Conclusion

The layered safety approach is the future of roadside work zone protection. By integrating traditional measures with innovations like the Metrolla Lightship, worksite managers can ensure unparalleled safety for their teams. As traffic volumes and construction projects continue to grow, embracing these technologies is not just recommended—it’s essential.
