BlinkerSign® Intersection Conflict Applications

BlinkerSign® Intersection Conflict Applications address conflicts at 2-way stop intersections by providing drivers (on both the major and minor roads) with real-time dynamic warnings of other vehicles approaching the intersection.

These systems consist of Vehicle Detectors on one or both roads triggered by approaching vehicles. Wirelessly triggered BlinkerSign® LED Signs or BlinkerBeacon™ signs then flash a real-time warning to signs visible by the drivers of the vehicles on both roads.

Major road traffic is warned with a flashing BlinkerSign™ or BlinkerBeacon™ indicating the potential for cross traffic (typically "Entering Traffic When Flashing" or "Watch For Traffic"). Motorists the minor road are alerted with flashing LEDs on BlinkerSign® R1-1 "STOP" signs.


  • Solar Powered/ Energy Efficient - Low cost
  • Combined effect of warnings to drivers on both roads provides drivers advance warning, reducing conflicts resulting in serious injuries or fatalities
  • Used by many state DOTs
  • Easy to install
  • Ideal for rural areas
