Traffic Operations Unit

The Traffic Operations Unit provides TSMO support for traffic signs, pavement markings, and work zone activities, and ensures that the traffic control devices are in compliance with the federal Manual on Uniform Traffic Control Devices. Traffic Operations is made up of three teams: Traffic Investigations Team, Business Sign Control Team, and the Work Zone Traffic Management Team. 

Frequently Asked Questions


Traffic Investigations works to increase travel time reliability and to improve safety for everyday travel, planned events, and unplanned incidents.  This group manages the state-owned pavement markings and over 70,000 state owned traffic signs through projects and work orders, making sure that they communicate essential information to drivers so that they arrive safely at their destination.  They also perform engineering studies for speed limits and other traffic regulations in support of the Traffic Committee, assist towns with sign, line, and road safety questions, and perform road safety reviews.  This team also assists with developing traffic management plans for long duration incidents and planned events, and contingency plans for short term incidents. 

The Business Sign Control team is responsible for administering the state’s Official Business Directional Sign (OBDS) program, maintaining travel information plazas located throughout the state, and providing staff support to the Travel Information Council (TIC).  This team also coordinates the activities of the Agency’s maintenance districts and the TIC to control illegal signs as defined by state law.

Work Zone Traffic Management works to minimize traffic impacts caused by highway construction activities.  This is accomplished by supporting the Agency’s Project Delivery Bureau, districts, and developers in developing sound Traffic Management Plans (TMP), supporting the Agency’s Construction & Materials Bureau with the implementation of those TMP’s, and playing a leadership role with Agency work zone related policies, guidelines, standards, and specifications.
