The Right Equipment for Optimum Traffic Control Services in Seattle

Having the right equipment is critical to high-quality traffic control services in Seattle. They are an extension of the flaggers, supervisors, and traffic controllers responsible for the safety of a project site along with all the workers, pedestrians, and vehicles affected by it.

Know Your Traffic Control Equipment

Here are just some of the basic equipment that should govern traffic on any worksite and how they are used.

  • Traffic Barricades
    This device can be fixed or portable. It can have one to three rails, and must have the correct markings. Traffic barricades help control traffic by delineating, closing, or restricting right-of-way for vehicles.

    Traffic barricades are further divided into three types:

    • Type I: Usually used on traditional city streets and roads
    • Type II: Have more visibility due to two sets of reflective tape
    • Type III: Installed on roads that are closed, either temporarily or permanently, and can encompass the entire road
  • Traffic Cones
    One of the most recognizable traffic equipment on the road, traffic cones should be placed on areas of immediate danger such as construction zones. They are vital for dividing opposing traffic lanes, dividing traffic lanes, and providing utility and maintenance work for a short term.
  • Barrels or Traffic Channelizer Drums
    Made from flexible, lightweight, and malleable materials, barrels are used primarily on highways and other high-speed driving areas.

    General guidelines for traffic control in Seattle state that channelizer drums should be a minimum of 36 inches in height plus at least 18-inch wide so they are clearly visible to drivers going at high speeds.

  • Advance Warning Signs
    Work zone warning signs are installed when the road construction requires a higher level of driver caution. These are used to attract attention to a specific hazard and warn the drivers and pedestrians of higher than normal potential risk.

    • Rigid signs must be mounted at least five feet above grade; retro-reflected rigid signs are used for night work
    • Flexible signs are installed at least one foot above grade

    Keep in mind that all warning signs must face at approximately right angles to on-coming traffic. This is to avoid reflecting sun glare into the driver’s eye.

  • Candle Sticks or Delineator Tubes
    These are skinny and tall channelizers available in different colors. They are also marked by alternating white segments for maximum visibility during night time and in all weather conditions.

    Unlike other traffic control equipment, these posts are most appropriate in places with minimal or low vehicle traffic. Their primary purpose is to define zones that are restricted to pedestrians, or to warn drivers of the low-speed requirement.
