The Traffic Engineering and Operations Division maintains traffic control devices, regulates traffic and studies and analyzes traffic flow to ensure safety and efficiency, and follows the Manual on Uniform Traffic Control Devices (MUTCD) to determine the appropriate use of traffic devices. These guidelines require certain criteria to be met before Traffic Engineering and Operations can use a particular device, as well as ensure that motorists have consistency among different communities throughout the country.
