Enhancing Active Transportation and Demand Management (ATDM) with Advanced and Emerging Technologies and Data Sources
Per the Federal Highway Administration (FHWA) Office of Operations, active transportation and demand management (ATDM) is defined as:
"…the dynamic management, control, and influence of travel demand, traffic demand, and traffic flow on transportation facilities. Through the use of available tools and assets, traffic flow is managed, and traveler behavior is influenced in real time to achieve operational objectives, such as preventing or delaying breakdown conditions, improving safety, reducing emissions, or maximizing system efficiency." (5)
ATDM solutions aim to leverage data sources and technologies to manage capacity and demand on facilities to reduce congestion and delay; respond to incidents and provide traveler information based on real-time data; and balance resources across active traffic management (ATM), active demand management (ADM), and active parking management (APM) for optimal solutions.
This document informs agencies of the technology and data sources available to modify and enhance their ATDM solutions from static/responsive management to truly proactive management. To identify emerging technologies and data sources, a detailed literature review was conducted. In addition, interviews with public agencies and private companies that implement ATDM solutions were conducted to determine what technologies and data sources are in use today. Listed below are the emerging technologies and data sources that are relative to the next-generation ATDM concepts and solutions.
Sample list of emerging technologies:

The literature search and interviews also provided information on what ATDM concepts agencies have planned for the future. ATDM implementations go through the same steps:
By incorporating the emerging technologies and data sources at each step, ATDM implementation will be improved. Use cases provide examples of how ATDM is accomplished now and what can be enhanced using new technologies and data sources.
Planning for ATDM implementation is a complex process and involves advanced planning. This report provides information for planning an ATDM implementation:
For the planning to be successful, design and deployment elements need to be considered. Data management, system platforms, and infrastructure need to be considered. Technology testing and public outreach are also important considerations. Operations and maintenance (O&M) are also an integral component in planning for ATDM enhancements. It is necessary to consider such items as cybersecurity, performance monitoring, costs, and future proofing.
This document concludes with several case studies that exemplify the use of ATDM solutions in conjunction with emerging technologies and data sources.
