The Traffic Engineering Division ensures that safe, efficient traffic control measures are standardized throughout the State Maintained Highway System. It is responsible for the development of programs to add, upgrade or revise existing traffic control devices. This task compels studies to determine and recommend appropriate speed zones as well as the development and distribution of policies for the application of traffic control devices in accordance with established guidelines.

Traffic Engineering Division directs the State-wide Intelligent Transportation Systems (ITS) efforts. This includes operation of the central Traffic Management Center (TMC) in Jackson, assisting with emergency and incident management, operation of the Advanced Traffic Management Systems (ATMS) system, and ongoing expansion of these systems in the Jackson Metro area, Gulf Coast, Hattiesburg, and Desoto County (Metro- Memphis area).

The in-house manufacture and distribution of MDOT erected signs is also under the direction of the Traffic Engineering Division. Personnel travel statewide to install and maintain signs and signals on assigned sections of state maintained highways.
