Data Subsystems and Data Management Plans for Traffic Management Systems

Traffic management systems (TMSs) are deployed in the United States to improve the efficiency, safety, and reliability of travel on designated portions of the surface transportation network. TMSs are typically large, complex systems, that consist of a number of subsystems (e.g., ramp metering, traffic signal control, dynamic message sign, data, traveler information, communication, software, hardware), as well as a range of components (e.g., dynamic message signs, detection devices/sensors, closed-circuit television cameras, signal heads, controllers, communication switches, servers, video wall, phones). TMSs capabilities could support different services, functions, tasks, or actions. For example, some TMSs manage only the vehicular traffic on freeways in each region, while others may manage the entire road network, which may include surface streets and freeways. TMSs may also have different roles and responsibilities (e.g., sharing roadway and traveler information) that involve sharing, coordinating, or making information available to other agencies, systems, or service providers (e.g., emergency services, transit). TMSs range in size (i.e., coverage area), functionality (e.g., incident management, ramp management), services (e.g., traveler information, managing traffic across institutional boundaries), and capabilities (e.g., whether or not the system includes a traffic management center, which can be used for sharing information). Significant changes have occurred with cloud options available to agencies to store data. TMSs have traditionally been designed with local servers and limited ability to modify or make changes. Technical options are available to support agencies making changes in the design, configuration, and technologies used to support a data subsystem (see Special Note A). Limited technical information and resources exist to help agencies assess the capabilities and evolving needs for TMSs data subsystems. There are limited resources to support agencies integrating the needs and requirements of data subsystems into the decisions made in planning and programming processes throughout the life cycle of a TMS (e.g., how to plan, design, or procure needed data storage and management capabilities). Agencies face challenges with systematically managing data as part of their TMSs operation. There are limited resources for agencies to use or to assist with data management (e.g., archiving, use, configuration, monitoring use), and issues with receiving, sharing or using data with third-party sources or within an agency (e.g., licenses, proprietary, sensitive information). Research is needed to help agencies better manage data in TMSs. The objective of this research is to develop two technical reports to support agencies' decision-making processes and frame the opportunities for agencies to consider when contemplating improvements to data subsystems and data management plans of their TMSs: (1) Report No.1, Data Subsystems for TMSs, and (2) Report No.2, DMP for TMSs.
