Smart Crosswalk In-Roadway Warning Light (IRWL) System

Smart Crosswalk™ helps keep pedestrians safe

Welcome to LightGuard Systems®. For over twenty five years Smart Crosswalk™ has helped transform neighborhoods, towns, cities and schools into safer places for pedestrians − and more walkable communities!

Over 70% of pedestrian accidents occur in the dark, which makes any busy crossing a potentially hazardous one. Our federally-approved lighted crosswalk systems help save lives by alerting motorists of pedestrians in a crosswalk.

Our best known products include In-Roadway Warning Lights (IRWLs), flashing LED signs, and other advanced traffic calming measures − and are the most effective roadway safety solutions available today.

Look through our products, and if you have a need for a lighted pedestrian crosswalk or other traffic calming solution, please contact us. We are here to help!

What is a Lighted Crosswalk System?

A lighted crosswalk system is a federally designated In-Roadway Warning Light (IRWL) system that we call Smart Crosswalk™. Smart Crosswalk™ is proven to significantly lower the chances of pedestrian crossing accidents. With Smart Crosswalk™, a strong street crossing safety measure is established. Smart Crosswalk™ ensures pedestrian safety with embedded in-pavement LED signal lights and optional yellow flashing LED warning signs.

Depending on the number of lanes in the roadway, a predetermined number of in-roadway warning lights are placed across the roadway ahead of the crosswalk lines. The lights automatically activate and begin blinking as a pedestrian enters the crosswalk zone. The lights are aimed directly at the line-of-sight of approaching drivers, alerting them that the crosswalk zone is occupied.

Manual on Uniform Traffic Control Devices (MUTCD)

Beginning in 1994, numerous stringent third party studies and testing procedures using LightGuard System® product. These studies successfully culminated in the acceptance of IRWL enhanced crosswalk lighting systems being adopted and incorporated into section 4L of the Millennium 2000 Edition of the Federal Highway Administration MUTCD.  They have subsequently also been adopted as a standard across the United States.

Invention and History of IRWL Systems

In 1992, Michael A. Harrison, CEO of LightGuard Systems Inc.®, a former pilot, invented IRWL enhanced crosswalk lighting systems after a friend was involved in a pedestrian accident. As the IRWL product pioneers and category creators, we received the Federal Highway Administration’s authorization to begin conducting IRWL experiments in 1993, and in 1994, incorporated the company. In May of 2002 our flagship Smart Crosswalk™ system received U.S. Utility Patent #6,384,742 B1 for a “system of lights that are embedded in the roadway at crosswalks.” We also hold two additional in-pavement signal lights patents for railroad crossings and signalized traffic intersections.

Our Mission

To reduce needless crosswalk accident, injury and death caused by driver inattention or limited visibility conditions.
