The Traffic Signal Design group is responsible for providing traffic engineering services as needed by the Roadway Design Section, Division Offices, and the Construction Bureau. This group's scope includes the aspects of traffic signal design; review of project plans; providing cost estimates; composing specifications for the required materials of a proposed traffic signal installation; reviewing electrical for use on traffic signal installations; manage the traffic signal design services contracts and coordinates with consultant's design and payment; and coordinating statewide standardization.

The Intelligent Transportation System (ITS) group is responsible for projects that typically include fiber optic communications networks, traffic surveillance CCTV, and machine vision vehicle tracking, detection and classification systems. The ITS group provides statewide oversight of designs and plan reviews for these projects. This group is also responsible for the development and review of specifications for projects, development of ITS Regional Architecture, and statewide implementation of projects. When ITS projects are designed outside the department, this group coordinates and reviews the plans and ensures the implementation of projects is in accordance to the approved State & Regional Architectures.

The Roadway Lighting System group is responsible for providing electrical engineering services as needed by the Roadway Design Section, the Utility Section, the Maintenance Bureau, the Bridge Bureau, the Equipment Bureau, the Construction Bureau, consultants, and the divisions. This group's scope includes all aspects of the electrical portion of a project, including analyzing street lighting warrants for FHWA participation, laying out of lighting and power systems to meet current design standards, using computerized methods to predict characteristics of a proposed lighting system, composing specifications for the required materials and installation techniques used on a project. When lighting projects are designed outside the department, this group coordinates reviews and approves the plans and all lighting permits.materials proposed.
