Abstract:Transportation management centers serve as the technical and institutional hubs that facilitate interagency coordination and integrate a wide range of traffic management strategies to achieve the collective goal of providing safe, efficient and sustainable transportation infrastructure. This report presents a study aiming at providing a nationwide scan on best practices in TMCs with a focus on ITS in terms of innovative tools, technologies, methods, and policies. A web-based survey was conducted focusing on current applications as well as new methods and tools in various aspects of TMC operations and services. The survey covers five major areas of interest - current tools and applications used in TMC operations, practices in data collection and information sharing, potential enhancements with new technologies, staffing and skill needs, and incident management performance measures. The questionnaire consists of both fact-finding and opinion-seeking questions. The former helps to shed light on the state-of-the-practices, while the latter provides a channel to understand the preferences and attitudes toward the implementation of emerging technologies and tools in TMC operations. The survey was conducted during March and April 2014. Initial recruit emails with link to the survey website were sent to over 80 TMC contacts around the nation. A total of 42 responses from twenty-five different states were received and analyzed. In terms of current applications by function area, the survey results indicate that TIM and Traveler Information are the two areas that are well developed where most of the tools received wide applications among the TMCs. In terms of practices in data and information sharing, a majority of the agencies exhibit positive attitude towards emerging methods and technologies and the associated applications in TMC services, such as integrated corridor management, and connected vehicle. Data gathering through external or alternative data sources shows potential for future growth, and many agencies indicated the desire to obtain data from other agencies such as arterial traffic conditions, transit information, parking availability information, etc. Regarding the trend and potential of advanced technologies, various applications in automation tools and advanced wireless technologies are being considered very useful to TMC operations. The most important strategies for facilitating the application of advanced technologies are documentation on all systems, fostering an embracing agency culture, and following system engineering processes. The results provide valuable insights for policy makers and developers in understanding the potentials of the various applications and how to best incorporate them to enhance TMC operations.
