Transportation Management Systems And Associated Control Devices


Transportation management systems and associated control devices encompass the hardware, software, firmware, and integration services that enable intelligent transportation systems (ITS).

The components, subsystems, and services used to design, install, operate, and maintain ITS include:

  • Dynamic message signs (DMS)
  • Portable traffic signal systems
  • Intersection (and other roadside device) controller hardware and software
  • NTCIP Communications interface devices
  • Traffic controllers and subassemblies, as well as associated software
  • Traffic cabinets, enclosures, load switches, and field terminals
  • Stationary and mobile traffic management centers
  • Transportation systems that sense vehicles (loops, video, and other technologies)
  • Environmental sensor systems

NEMA offers access to expanded markets through the adoption of performance-based Standards and a unified industry position for all aspects of ITS.
