    The Traffic Standards Unit has a wide variety of expertise related to roadway signing, striping, traffic structures, traffic control plans, traffic signals, and illuminations. The unit's primary purpose is to develop and maintain standards for design and construction, review contract plans, provide training in design and construction inspection, and asset management of signs, signals, and traffic structures. The unit also provides standard drawings, special provisions, and specialized work as needed. This unit consists of five teams providing expertise in the following areas: Signing and Striping, Traffic Signals, Traffic Structures, Traffic Control Plans, and Illumination.
Traffic Standards Disciplines Traffic Standards Disciplines
Signs & Striping
SIGNING - Provides engineering expertise and maintains standards for all highway signs (see Sign Policy and Guidelines in Publications section). 

STRIPING - Provides engineering expertise and maintains standards for striping and pavement markings (see Traffic Line Manual and Striping Design Guidelines in Publications section).

Traffic Control Plans
Develops the traffic control plans for construction projects. When construction projects suspend the normal function of the roadway, a traffic control plan is developed to assure the safety of all road users, and the protection of workers. At the same time, the traffic control plan provides for continuity of the movement of motor vehicles, bicycle and pedestrian traffic while allowing for the efficient completion of the construction project.

Illumination
Information on Illumination design, specifications, design manuals and approved products can be found on this page.
Signals
Provides engineering expertise for temporary traffic signals, permanent traffic signals, flashing beacons, ramp meters and some portions of weigh stations. The team also develops specifications, maintains standard drawings, and maintains qualified products lists. The team also reviews local agency and developer agreements and plans for traffic control devices, reviews new products, maintains asset management databases, and provides annual training and certification for inspectors of traffic signal construction.
Structures
Provides engineering expertise and designs for sign bridges, cantilever sign supports, traffic signal poles, illumination poles, VMS supports and other miscellaneous traffic structures.
