Traffic Management Centers (TMCs) are the "brains" for most freeway and arterial management systems. TMCs monitor and manage the traffic flow and the transportation network, as well as provide traveler information through the deployment of various Intelligent Transportation System (ITS) technologies and proactive management strategies. A TMC also functions as the technical and institutional hub that facilitates interagency coordination and integrates a wide range of traffic management strategies to achieve the collective goal of providing safer, more efficient and sustainable transportation infrastructure to meet the mobility needs. The success of a TMC directly influences the efficiency of the transportation network, the economic competitiveness of a region in moving people and goods, and the quality of life for the communities. The intent of this research is to review the state-of-the-practice in TMC operations in order to increase the understanding of the common features that have led to their success. This benchmarking process will help in establishing a general standard in TMC performance, and provide the opportunity for information exchange and sharing among the agencies that will lead to improved performance and services. This research will add to the literature by providing an updated and comprehensive scan of current practices in TMC operations. The results of this study will help agencies assess their practices, learn from others' experiences, improve the performance and services of the centers, and eventually contribute to the efficient management of the transportation network and effective implementation of technologies in responding to traffic conditions and emergencies (such as incidents, special events, and other recurring and non-recurring delays). |
