TraxAlert™ Advanced Grade Crossing IRWL Warning Light System

TraxAlert™ Advanced Grade Crossing IRWL Warning Light System

TraxAlert RR Grade Crossing Safety System

TraxAlert™ applies in-roadway warning lights (IRWL) – a proven traffic calming method that’s shown to significantly increase motorist stopping yield rates and reduce pedestrian crosswalk injuries – to RR grade crossing.

According to the US Department Of Transportation, there are 240,528 at-grade highway-rail crossings in the United States. Even with gates and signal lights, nearly 50% of vehicle-train collisions occur at crossings with these types active warning devices.

TraxAlert™ features & benefits:

  • Advanced warning light system specifically designed for Railway Crossings
  • Improves drivers’ attention and awareness via flashing IRWL’s and LED enhanced signs
  • Reduces accident-injury rates resulting from downstream intersections and crossing backups
  • Enhances overall rail grade crossing system effectiveness with the use of LightGuard’s IRWL system controller
  • Can be synced-up (via our controller) with existing gates and alarm systems, or interfaced into existing signalized downstream queuing.
  • Defines where vehicle stops
  • Provides a safe vehicle buffer zone


  • Quiet zones
  • Metro tram rail crossings
  • Dark country railroad crossings
  • Intermodal railroad terminals
  • Commercial facilities
  • Train yards

How the system works:

Red and amber colored LightStar™ 9X LED in-roadway warning light fixtures are embedded across the roadway in front of the railroad tracks. The LGS-9X light fixture is housed in our rugged case-hardened 14″ Steel Snow Plow Resistant base plates.

The row of amber lights are located at the stop bar line; this defines where to stop, providing a safe buffer zone to motorists.

The IRWL fixtures flash upon train activation. First, the red lights flash in a quick strobe pattern, then stay solid on until the train clears the track crossing zone. The amber lights flash continuously for the duration of the train’s crossing.

When optional flashing high-intensity LED cross buck railroad signs are used, they are simultaneously activated in combination with the advance warning amber IRWLs. Although the TraxAlert™ system can be a standalone product, it is typically used in conjunction with pre-existing railroad grade crossing alarm systems.

Featured Installation – 2017 Elk City Study

On Monday, September 18, 2017, LightGuard Systems’ TraxAlert™ ‘Lit Up’ the 7th St. RR Grade Crossing in Elk City, Oklahoma. A demonstration was held with representative from several agencies, including Volpe National Research Center, Farmrails, City of Elk City and the Oklahoma Department of Transportation (ODOT). This illuminating event commemorates the first installation and study of TraxAlert™ LED in-roadway warning lights (IRWL) used at a RR Grade Crossing in the state of Oklahoma. Funded by the USDOT Volpe National Research Center, the study will evaluate traffic behavior and motorist stopping yield rates before and after the IRWL installation. Results will be available in early 2018.
