Transportation Technology

In the late 1990s, Liddell began installing Intelligent Transportation System (ITS) equipment and related structures, and the company has incorporated this specialty into its portfolio of roadway contracting projects. Our experience includes the construction, installation, integration, and testing of a wide range of ITS and related communications equipment, such as:

  • Changeable message signs, including travel time displays
  • Highway cameras
  • Ramp meters
  • Bluetooth readers
  • Radar vehicle detectors
  • Tolling equipment
  • Hardwired central and field communications equipment, including fiber optic and wireless systems

Today, the Technology Division within the company provides construction, maintenance, and consulting services for ITS, communications, and technology projects.
