About Us

The U.S. DOT Volpe Center’s Systems Safety and Engineering Division conducts original engineering research and analysis to improve transportation safety, capacity, and resiliency. We also provide program management, monitoring, and technical assistance services for federal multi-billion-dollar capital improvement programs throughout the United States.

Our Capabilities

Systems and Infrastructure Modernization and Optimization

• Provide technical oversight of federal investments in capital improvement projects, which includes technical, analytical, and project management in the planning, development, operation, and evaluation of federal infrastructure grants (e.g., Amtrak, Transportation Investment Generating Economic Recovery (TIGER)/Better Utilizing Investments to Leverage Development (BUILD), Consolidated Rail Infrastructure and Safety Improvements (CRISI), State of Good Repair (SOGR), etc.).
• Provide technical expertise on major projects for FHWA and FRA, transportation performance management and asset management, enterprise risk management, infrastructure emergency relief funding, and strategic management support for the FHWA Federal-Aid Highway Program.

Engineering and Technology Deployment to Enhance Transportation

• Conduct innovative research, development, and demonstration activities to examine engineering, education, and enforcement methods that can be used to reduce casualties at grade crossings and due to trespassing on railroad and transit right-of-way, including Highway-Rail Grade Crossing Safety and Trespass Prevention Program Research and Connected Vehicle at Highway-Rail Grade Crossings Research.
• Conduct risk analyses, network capacity modeling, fire safety and emergency preparedness studies, data management, program planning and energy, and environment and engine technology research to address system-wide research challenges facing FRA and the rail industry.

Safety and Security Assessments

• Support fire safety and rail grade crossings research and development (R&D), as well as Americans with Disabilities Act of 1990 (ADA) station assessments.
• Review transportation safety regulations, and support standards development and implementation.

Applied Data Science

• Support innovative rail safety solutions to reduce casualties on railroad and transit systems and enable performance-based decision-making for the FHWA Federal-Aid Highway Program.
• Leverage artificial intelligence (AI) and unmanned aircraft system (UAS) technologies to support our R&D portfolio.

Knowledge Transfer and Capacity Building to Maximize Impacts

• Provide technical assistance and training on regulatory compliance, safety assurance, and strategic infrastructure management.
• Integrate the dissemination of research results and sharing of peer knowledge within stakeholder communities throughout our body of work.

She previously served as the deputy chief of the Transportation Planning Division, one of the U.S. DOT Volpe Center’s largest divisions.

Maloney serves as the U.S. DOT Volpe Center’s Grants Portfolio manager. Previously, she led the U.S. DOT Volpe Center’s technical merit review team of 50 staff for TIGER/BUILD/RAISE infrastructure grants from 2018 to 2022. From 2014 to 2020, she served as the Transportation Performance Management technical lead, coordinating support to FHWA and FTA.

Maloney is a skilled facilitator and recently served as implementation advisor for the FHWA Global Benchmarking Program's Building Information Modeling team. She also supports various U.S. DOT Volpe Center internal change management initiatives. Prior to joining the U.S. DOT Volpe Center, she worked at NASA in the Office of Space Science. Maloney has a Bachelor of Arts degree in Government from Skidmore College, has a Master of Science degree in International Affairs from the Georgetown University School of Foreign Service, and is a graduate of the Presidential Management Fellows Program.

William Baron

Computer Engineer

William Baron has been a computer engineer at the U.S. DOT Volpe Center since 1987, and during this time has conducted analyses and development in every mode of transportation. He has developed technological systems to enhance security and efficiency in transportation systems at the nation’s borders, at the U.S. Capitol and at military facilities at home and abroad. Baron has developed secure portals for transit tunnels and systems for tracking military cargo and vehicles. He has conducted assessments of systems to enhance railroad and highway safety and has implemented intelligent transportation technologies at national parks.

Baron has developed security plans for FAA telecommunications, State Department freight transportation, and for the reconstruction of New York’s World Trade Center complex. He served as the DOT representative on the National Science and Technology Council’s Subcommittee on Biometrics and Identity Management. He developed entry point screening systems for the U.S. Army and the U.S. Special Forces, and he piloted automated inspection systems for pre-screened travelers at U.S. ports of entry. Baron has assessed cybersecurity in the aviation, maritime, transit, and pipeline environments. Currently, he is studying the use of drone technology and photogrammetry for modeling railroad grade crossing profiles, and he is managing cybersecurity for U.S. Air Force air traffic control systems. In March 2020, Baron was named the U.S. DOT Volpe Center’s Technology Transfer Outreach Program Coordinator. Baron holds a BS in Management Engineering from Worcester Polytechnic Institute and a MS in Management Information Systems from Northeastern University.
