Our advanced communications network is at the core of everything we do at the Traffic Operations Center. Macomb County's use of technology is critical to monitoring real-time traffic flow, signal operations, and managing emergency responses to incidents on the roadways.
The Macomb County Communications and Technology Center (COMTEC) is a 25,000-square-foot state-of-the-art facility at the Department of Roads that monitors road conditions for the department, residents, motorists and first responders. It is equipped to monitor, manage and respond to everything from a routine traffic crash to an escalating emergency event. The Department of Roads is equipped to deliver a safe, efficient, informative, and reliable traveling experience to the motoring public.
The mission of the MCDR Traffic Department is to provide traffic engineering expertise and leadership for providing safe and efficient transportation in Macomb County. The Department is supervised by John Abraham, Director of Traffic and Operations. One of the primary responsibilities for the Traffic Department is to oversee the installation and maintenance of all traffic control devices in Macomb County. Traffic control devices include traffic signs, traffic signals and pavement markings. The Traffic Department performs traffic studies covering a wide range of issues from installation of stop signs, speed limits and parking restrictions to the installation of traffic signals. The purpose of traffic control devices is to promote safety and efficiency by providing for the orderly movement of all road users on streets and highways in the County. All traffic control devices are installed after careful engineering study using the Michigan Manual of Uniform Traffic Control Devices.
The Traffic Department works closely with the Engineering Department to ensure that new roadways are built with roadway safety in mind using appropriate curvature and lane configurations.
The Sign Department works under the direction of our Traffic Department installing and maintaining all the traffic control signs, guardrail installation and pavement markings. The Sign Department oversees painting of all of the roads maintained by the Department of Roads. Currently, the Sign Department maintains approximately 60,000 traffic control signs. When critical signs (such as stop signs) are knocked down, the Sign Department's emergency crews are dispatched to re-install the sign immediately. To report a down or damaged sign, contact 586-463-8671, 24-hours a day.
The Signal Department is also under the direction of the Traffic Department and maintains all of the approximately 1,000 electrical traffic control devices in the county. We currently maintain all of the traffic signals in Macomb County, including all of those that are located on local and State roads.
To report problems with a traffic signal, contact 586-463-8671, 24-hours a day. The Signal Department routinely changes all of the light bulbs in traffic signal once a year to prevent bulbs from burning out unexpectedly. Many signal indications are now LED and do not require annual replacement. We also perform routine maintenance and operation checks at each intersection to ensure that all of the equipment is operating properly.
