In-Roadway Warning Light (IRWL) System — Santa Rosa, CA — Lightguard Systems

Congratulations on taking the first step towards significantly reducing pedestrian accidents and injuries with a LightGuard Systems Smart Crosswalk. An investment in a Smart Crosswalk heralds a safer environment for pedestrians and motorists by increasing visibility of pedestrians during high traffic, nighttime, and in sub-optimal, or obscured visibility conditions.


Smart Crosswalk is an ideal pedestrian enhancement for applications such as public crosswalks, school zones, airports, trail crossings hotels and casinos, corporate and college campuses, shopping malls, parking facilities, and hospitals.


Smart Crosswalk In-Roadway Warning Lights (IRWL)

LIGHTGUARD's IRWL systems are MUTCD compliant and a proven method of increasing driver awareness up to 95%. A typical system is comprised of:

  • Lightstar M11 in-roadway warning lights installed on both sides of the crosswalk
  • Durable base plates, 10” composite or 14” steel
  • Automatic activation bollards or push-button activation method
  • Solar or A/C power source (wireless option available)
  • Controller, battery back-up, and lockable weatherproof cabinet
  • Flashing LED warning signs or RRFBs

Selecting the Right Components for a Lighted Crosswalk System

  • How Many In-Roadway Warning Lights?

    • The number of Lightstar™ M11 in-roadway warning light fixtures needed depends on the number of lanes in the roadway. A typical two-lane road requires five lights embedded into the roadway on each side of the crosswalk—for a total of ten lights, plus ten base plates.
    • The placement of the lights in the roadway faces away, outward from the crosswalk’s center, to alert oncoming motorists in either direction. Similarly, a typical four-lane road requires seven lights facing outward in each direction for a total of fourteen lights plus fourteen base plates. 
  • Base Plate Options

    Base Plates protect and house the in-roadway warning lights—and are purposefully designed for durability and resistance. Our proprietary Debris-Free Self Clearing™ feature is built into the base plate. This design compresses the air so vehicle tires “jet out” the accumulated rubble through the fluted air channels. (See Figures 3 and 4)


    Standard 10” Composite Base Plate 

    • Our 10” x 1.5” standard composite base plate model is made of ultra-high-strength composite material. It is designed to be permanently embedded into the roadway.

    Steel Snow Plow Resistant 14” Base Plate

    • For regions where snowplows clear roadways, we offer a 30 lbs., 14″ x 1 1/2″ steel base plate designed to protect against a snowplow blade striking the base plate. 
  • Activation Methods

    • Smart Crosswalk™ activates in one of two ways: automatically via bi-directional infrared sensors (bollards) that are passively triggered as a pedestrian enters the crosswalk from either end; or by manual push button.

    • Each activation method has its benefits. However, the combination of both bollard and push-button activation is recommended to ensure optimal safety—as some pedestrians are more familiar and compliant with pushing a button, while others are not. 

    • If only one activation method is used, we recommend our T6 or long range T6L Automatic Activation Bollard. Infrared sensors are encased inside a set of bollards (free-standing columns) installed at both entrances to the crosswalk. In addition to providing optimal pedestrian safety, bollards also offer an attractive and easily recognizable visual entry point that features a NightGuide™ courtesy lamp/light—which gently illuminates the crosswalk entrance and invites the pedestrian to cross the street at the safest place.

    • Bollards come in standard white color. Custom colors are also available.

    • Bollards have standard Lightguardian NightGuide™ graphic.  Custom graphics also available.
  • Type of Power

    • Driven by your project’s power source location, budget, sun exposure, and other considerations, Smart Crosswalk™ can be configured to work with an existing A/C power source, solar power—or both. At locations where the cost of bringing a standard power supply to the Flashing controller is too high, solar power may be the best option.

    • Power source selection, either A/C or solar, is often determined by the distance between the IRWL system to the power source. Should costs related to bringing a standard power supply to the Power Control Unit (PCU) location be excessive, solar is a good alternative. Be aware, however, that in places where solar systems will encounter shade conditions, a decrease in solar charge to the batteries will occur.

    • Solar powered systems: LightGuard staff will be glad to assist you in assuring proper system operation and recharge for your location using our LGS – SolarCalculatorTool™.
  • System Controllers

    The Flashing Controller (UC) functions as the “brain” of your lighted crosswalk system. It allows the user to set up/activate the timing of the IRWL flashing lights, monitor the system, and capture data. A fail-safe feature automatically warns users of any system malfunction. We offer:


    Universal Controller (UC)

    • The advanced Universal Controller can monitor and store data such as time, date, and movement in each crosswalk direction. It can be programmed to turn on automatically at a specific time and then revert to standby mode for regular operation. 

    • The UC can monitor and store data such as time, date, and movement in each crosswalk direction. It can be programmed to turn on automatically at a specific time and then revert to standby mode for regular operation. It contains instantaneous battery backup power in the event of a power failure. The advanced controller can accommodate additional pedestrian safety features such as the use of flashing beacons, simultaneous yet independently activated crosswalks, remote communication, and other custom-based applications. 

    • The UC can also accept inputs from non-typical activation methods – motion sensor, radar, loop detectors, wireless radio transceivers, etc.  The 4 Solid State outputs can be custom programmed for almost any type of flashing output requirement which visually alerts motorists to the presence of pedestrians inside, or about to enter, the crosswalk.  The flashing output duration is factory preset & is field adjustable to allow pedestrians adequate street crossing time.  The programmable logic controller user interface consists of keypad + LCD.  LightGuard Systems’ proprietary software provides effective, reliable operation allowing the user to adjust the system parameters.  All outputs are software controlled and configured by the factory.
  • Flashing LED Pedestrian Warning Signs

    • Flashing LED Warning Signs complement our Smart Crosswalk™ system. They offer an additional level of safety by reinforcing existing traffic control measures.

    • A typical Smart Crosswalk™ configuration includes LED signs on both sides of the street. For an enhanced level of visibility, and depending on the street configuration, you may consider our back-to-back sign option (for a total of four signs).

    • LED warning signs are available in a variety of standard sizes (30″, 36”, and 48”), as well as customized sizes. All LightGuard’s signs can be powered via A/C and/or solar power sources, including solar wireless.
