Mission Statement: The mission of the Traffic Management Systems Section is to increase the effectiveness of the existing transportation infrastructure and provide real-time information to motorists through research, and the development and deployment of advanced surveillance, detection, communications, information processing, data management, and traffic systems.
Motto: "Moving North Carolina Through Innovative Technology"
|
| | |
| Every aspect of our lives is touched by the rapid progress of technology, including transportation. The North Carolina Department of Transportation realizes the need to improve highway operations,increase the effective capacity of the highway system, and enhance motor vehicle safety through increased utilization of our existing infrastructure. |
| |
| The Traffic Management Systems Section was established in 1993 to address these issues by the implementation of intelligent transportation systems (ITS) on the State Highway System. ITS technology can create a fundamental change in the way traffic engineers address our transportation system. |
| |
| One example of ITS is an advanced traffic management system (ATMS). This technology links the vehicle, driver, and highway into an integrated traffic control system that allows for two-way, real-time communications between the vehicle operators and the highway making traffic safer, more efficient, and environmentally sound. |
| |
| An example of this technology is: When cars collide on a freeway, a sensor will detect drastic changes in speeds, and the Traffic Operations Center will be alerted through the communications system. A closed circuit television (CCTV) camera scan is initiated, the accident is viewed by the traffic operator, and the appropriate emergency response is dispatched. Concurrently, the changeable message signs and highway advisory radios transmit detour messages to motorists. Thus, traffic flow is maintained with minimal interruption, secondary accidents are decreased, and vehicle emission pollutants are reduced. |
| |
| The Traffic Management Systems Section is responsible for preparing the detailed plans, functional specifications, and estimates for the implementation of all intelligent transportation systems installed on the State Highway System. These systems may include freeway management traffic surveillance, incident detection, fog detection and early warning, and reversible lane systems. |

Central Computer Based Traffic Signal Systems - The Section is responsible for planning, designing, and implementing central computer based traffic signal systems installed within municipalities. These systems simultaneously monitor and control traffic signal operations and displays for signalized intersections within urban areas. Central computer based systems allow the central computer to select a predetermined traffic signal timing plan which is best suited to the current traffic conditions. The systems range in size from 70 signalized intersections to over 400 signalized intersections.
|
|
Utility Make-Ready Plans - Utility make-ready plans are prepared for use by utilities to secure proper clearance separation for all communications cable installed on projects which are designed by the Section. This requires investigating existing utilities and determining the adjustments needed to meet the requirements of the National Electrical Safety Code.
|
|
Closed-Loop Traffic Signal Computer Systems - The Section works closely with the Signals & Geometrics Section in preparing construction plans and specifications for closed-loop traffic signal computer systems which are implemented on corridors.
|
|
Evaluating Technology - The Section continually evaluates analog and digital communications media and equipment, traffic applications software, CCTV camera equipment, and other advanced electronic technologies to determine the most appropriate and cost effective application.
|
| The Traffic Management Systems Section interacts extensively with the Congestion Management Section in scoping and planning projects to determine the cost-effective utilization of ITS technologies. The Section is the source for technical guidance and assistance to the Construction Branch during the construction phase. |
| The Section strives to demonstrate effectiveness and reliability of ITS technologies and promote their widespread implementation. With central computer-based signal systems, incident detection systems, traffic surveillance systems, and traveler information systems networked together, traffic engineers have a far more effective "box of tools" than separate, stand-alone systems. |
