• Abstract:
  The metal cabinets that house traffic signal ; controllers are a common sight at most ; intersections in Florida. Traffic engineers use them ; to time signal changes and facilitate the flow of ; traffic through an intersection. At the core of this ; device is the actuated signal controller (ASC), ; commonly known as a traffic signal controller, ; which takes in a variety of information and adjusts ; the timing of traffic signals. Prior to use, traffic ; controllers must be tested to verify that they ; are working as designed and as programmed. ; However, many different companies manufacture ; traffic controllers, and testing them requires an ; individualized protocol for each manufacturer, ; which makes testing them complex and timeconsuming. ; Fortunately, standards for traffic ; controllers have recently been developed as part ; of the National Transportation Communications for ; Intelligent Transportation System Protocol (NTCIP) ; which allowed the development of a test tool that ; could automatically test any traffic controller, ; regardless of their proprietary protocol, as long as ; the controller conforms to the NTCIP.
