Mr. Chandler also developed multiple FTA external guidance documents related to all hazards, safety, security, and emergency preparedness. Mr. Chandler is well versed in state safety oversight (SSO) program development and operation of oversight activities from both the FTA and state perspectives. He supports the operation of the SSO program in multiple states. In the six years following the acts of terrorism on 9/11, Mr. Chandler led a team of security and emergency management experts to provide technical assistance to 25 of the largest 50 transit agencies in the United States. Mr. Chandler also has experience in supporting safety assessments for communications-based train control (CBTC) and positive train control (PTC) projects. He is an instructor for the Transportation Safety Institute Safety Management System curriculum, and has received the Transportation Safety and Security Program Certificate for Rail.
Mr. Ryan McKinley has 20 years of engineering and scientific research experience, including technical leadership and management of a number of programs involving development and safety analysis of concepts/technologies pertaining to railroads, heavy rail transit, automated people-mover (APM), monorail, and automotive systems. His primary focus is safety of processor-based control systems, including communications-based train control (CBTC), positive train control (PTC), interlocking control, and advanced train control technologies (ATC) in general. Safety standards/guidelines/regulations experience includes MIL-STD-882, AREMA Section 17, IEEE 1483, IEEE 1012, EN 50126, EN 50128, EN 50129, EN 50159, ISO 26262, IEC 61508, and 49 CFR Part 236 Subparts H and I, among others. He has worked with US Class I and passenger railroads for the past seven years generating FRA-required PTC implementation and safety plan documentation. He has acted as Independent Safety Assessor (ISA) program manager for New York City Transit CBTC programs and has generated and assessed safety case documentation for various advanced train control products and systems internationally, including Copenhagen Metro, WMATA, BART, LA Metro, PATH, Sao Paulo Metro, San Juan Tren Urbano, London Underground, and APMs in Munich, Minneapolis, Detroit and the Middle East. In addition to his transportation safety experience, Mr. McKinley has led and supported safety/risk programs for nuclear weapons maintenance systems, chemical demilitarization systems, servo and PLC-controlled US Air Force (USAF) C-17 training simulators, USAF OH-58F aircraft weapons systems, and CBRN terrorism.
Mr. Don Eldredge has over 35 years of experience leading a variety of technical programs for government and industry, including work performing safety analysis and audits of railway and aircraft control systems. He has extensive experience in rail transit operations procedures and planning for safety, security, and emergency management through work with FTA and State Safety Oversight (SSO) programs, as well as other transit agency-specific projects in security and emergency management. He has co-authored a number of guidance documents developed for FTA and was actively involved in the FTA’s Office of Safety and Oversight development of the MAP-21 processes, focusing on the development of Risk-Based Safety Management System (SMS) processes that will enhance transit agency, state, and FTA safety programs. Mr. Eldredge previously worked at the FAA Technical center in the Aircraft Certification Research Branch, where he developed Integrated Assurance methodologies to be used for certification of digital systems on aircraft.
Mr. Jonathan F. Luedeke is an industry leader in safety assessments of systems, equipment, technologies, and concepts for transit, railroad, high-speed rail, automotive, bus, people-mover, avionics, and defense industries. Assessments led and performed by Mr. Luedeke include safety analyses and safety audits of safety critical signaling/train control systems/equipment, including communications-based train control (CBTC) and Positive Train Control (PTC) technologies, as well as the development and assessment of safety assurance processes. Assessments are based on leading safety standards and regulations such as MIL-STD-882, AREMA (Section 17), IEEE 1483, IEEE 1012, Title 49 CFR 236 Subparts H and I, CENELEC, and others, as well as his experience and knowledge of current industry practice gained over his 34-year career in rail safety. He assessed safety V&V methodologies worldwide in the rail, defense and other industries and developed a practical safety V&V methodology for the Volpe National Transportation Systems Center and the FRA that served as basic information for the Railway Safety Advisory Committee (RSAC) in development of the FRA rule in 49CFR236 Subpart H. Much of the information in the associated report in that program was utilized in Section 17 of the AREMA standards. He also has experience assisting clients in cross-acceptance activities in which safety cases developed according to CENELEC standards were assessed against US safety standards and practice.
Denny R. Stephens, Ph.D., has over 35 years of experience in research, development, field deployment, testing and demonstration of new technologies that improve vehicle safety and mobility, such as connected vehicle and autonomous systems, as well as safety of vehicle energy storage systems such as natural gas, hydrogen and Li-ion batteries. Dr. Stephens has been a leader for decades in developing structured safety strategies for complex vehicle systems. Dr. Stephens is a respected leader in the development, field deployment, testing and demonstration of vehicle safety technology for the USDOT. He led a multi-contractor team, including vehicle manufacturers, in successfully integrating new and retrofit connected vehicle technology in commercial vehicles and in implementing them in the USDOT Safety Pilot Model Deployment. He recently led the successful integration, field deployment, testing and demonstration of Intelligent Network Flow Optimization (INFLO) connected vehicle mobility and safety applications with Washington State DOT along I5 in Seattle. Dr. Stephens assembled and led a multi-disciplinary research team in analyzing safety issues in Li-ion batteries and Li-ion battery vehicles. He developed a comprehensive map for the initiation and progression of Li-ion battery failures in vehicles. Dr. Stephens led and managed a five-year program for the U.S. Department of Transportation (USDOT) to assess safety performance of hydrogen fuel cell vehicle fuel systems under crash conditions similar to those prescribed in the existing Federal regulations. Dr. Stephens’ team generated data and performed research-oriented fuel system integrity testing of hydrogen vehicles, hydrogen fuel systems, and fuel system components such as storage containers , container assemblies, valves, pressure relief devices, and packaged fuel systems.
Mr. Josh Gearhardt has over 14 years of experience in the public and private sectors, providing leadership in the areas of program , operational , and financial management. Mr. Gearhardt has a detailed understanding of the inner workings of transit agencies from experience working directly in transit at the local and state agency levels.
