Florida Department of Transportation (FDOT) Express Toll Lane Modeling Workshop Peer Review Report

Appendix C Peer Review Panel Biographies

C.1 Scott Ramming (DRCOG)

Scott Ramming has over 20 years of experience developing and applying transportation models. He has experience estimating and using models in Saint Louis; the New York Metropolitan area; Boston; Hong Kong and Guangdong Province, China; as well as applications to high-speed airport access lines and privately-financed toll roads. His doctoral thesis at MIT developed the Path-Size Logit formulation for correcting for path overlap within a multinomial logit context.Path-Size Logit has been used for international applications to auto and transit paths, and is now a standard component of commercial transportation modeling software such as TransCAD. Scott developed a four-step trip-based model -- "from scratch" in some areas -- for the I-70 Mountain Corridor Programmatic EIS that covers roughly half the State of Colorado. The task included estimating mode choice models from stated-preference surveys for modes such as an Advanced Guideway System unlike anything currently in use in North America. Scott now works refining and adding functionality to DRCOG's activity-based model, Focus.

C.2 Matthew Kitchen (PSRC)

Matthew Kitchen was formerly the Program Manager for Development at the Pudget Sound Regional Council.

C.3 Kara Kockelman (University of Texas)

Professor of Civil, Architectural and Environmental Engineering at the University of Texas at Austin, Dr. Kockelman is a registered professional engineer and holds a PhD, MS, and BS in civil engineering, a Masters of City Planning, and a minor in economics from the University of California at Berkeley. She has received the NSF CAREER Award, U.C. Berkeley's University Medal, MIT's Technology Review Top 100 Innovators award, CUTC's inaugural Young Faculty Award, the Regional Science Association International's Hewings Award, and ASCE's Bartholomew Award and Huber Research Prize.

Dr. Kockelman's primary research interests include the statistical modeling of urban systems (including models of travel behavior, trade, and location choice), energy and climate issues (vis-â-vis transport and land use decisions), the economic impacts of transport policy, and crash occurrence and consequences. She has taught classes in transportation systems, transport economics, transport data acquisition and analysis, probability and statistics, design of ground-based transportation systems, and geometric design of roadways.  She has chaired TRB's Travel Survey Methods committee for several years and served on TRB's Transportation and Land Development, Transportation Economics, and Statistical Methods committees.

C.4 Yi-Chang Chiu (University of Arizona)

Yi-Chang Chiu, Ph.D., is an Associate Professor of Transportation at the University of Arizona. Dr. Chiu's research interests include dynamic traffic assignment, multi-resolution traffic assignment simulation modeling, mass evacuation network modeling, and urban system dynamic modeling, border security modeling, and intermodal transportation modeling. Additionally, Dr. Chiu is well-researched in critical infrastructure management and response, mesoscopic traffic flow theory, and telecommunication technologies in ITS applications. Dr. Chiu received his doctorate in Transportation Engineering from the University of Texas at Austin.

C.5 Eric Pihl (FHWA)

Eric is  a member of the FHWA Resource Center Planning team where he provides training and technical assistance to support the application of passenger and freight forecasting and analysis methods. A member of the TRB committee on Travel Behavior, he has contributed to national research projects focusing on technical methods for planning and project and instructs workshops on statewide, metropolitan, and operational planning methods. Eric holds an MS in transportation engineering and a Master of City Planning from Georgia Tech.

C.6 James Sturrock (FHWA)

C.7 Hugh Miller (CDM Smith)

Hugh Miller has over 40 years of experience in transportation planning and engineering, working in a variety of consulting and academic positions. His experience as consultant ranges from project management to the supervision of large, diverse professional groups. Hugh is a recognized expert in T&R studies, specializing in travel demand modeling, traffic engineering and project planning. His experience covers toll feasibility studies through investment grade T&R studies. Hugh has presented findings to rating analysts, bond insurers, investors and the FHWA (as part of TIFIA loan applications). For more than 20 years, he led the T&R Consultant at Florida's Turnpike Enterprise. He is now Vice President of CDM Smith, where he serves as Lead Practitioner and Discipline Leader of the Toll Services Discipline.

C.8 Bill Olsen (CDM Smith)

Bill Olsen has specialized in travel modeling using the Florida Standard Urban Transportation Model Structure since 1986.  He was a contributor to the development of FSUTMS Data Update Project (Methodology for Using Data in Standard Models) and Model Update Phase V Project (Improvements to the Florida Standard Urban Transportation Model Structure). His most recent experience with the forecasting of toll facility traffic for projects in Florida has included the Veterans, Suncoast Parkway, and Daniel Webster Expressways.  From 1969 to 1986 he served as Associate Professor with Florida State University's Department of Urban and Regional Planning and Director of the Transportation Planning Specialization.  Dr. Olsen is a Registered Professional Engineer in Florida and his Master's and Doctoral Degrees in Transportation Engineering were earned at Northwestern University

C.9 Peter Vovsha (PB)

Peter Vovsha has 28 years of experience in the development and application of transportation models. He has developed numerous models and computerized procedures for advanced discrete-choice models of travel behavior and integrated multi-modal network simulations. As a principal modeler, he has developed transport models for several large-scale regional model development projects in major cities such as Moscow, Tel-Aviv, Jerusalem, New York, Columbus, Montreal, and Ottawa. Peter is one of the leading experts in the development and application of the advanced tour-based and activity-based model systems in practice. He is pioneering in design of the new generation of advanced activity-based models that has been widely adopted in U.S. and worldwide (8 out of 12 activity-based models developed or being developed in practice in the U.S. were designed by him).

C.10 Jim Ely (HNTB)

Jim Ely is chairman of HNTB's national toll practice. Ely is based in the firm's Tallahassee, Fla., office and joined HNTB in 2010. He served as vice chairman of the toll practice. Prior to joining the firm, he worked for the Florida Department of Transportation for 36 years. During that time he served as executive director of Florida's Turnpike Enterprise for 21 years, overseeing one of the largest toll programs in the nation. Ely is well known within the transportation market, having served as past president of the International Bridge, Tunnel and Turnpike Association in 2007. He remains active in the organization, chairing committees and organizing programs. Ely is a founding member and currently serves on the board of directors of the Transportation and Expressway Authority Membership of Florida, also known as TEAMFL. The organization includes statewide expressway and transit authorities, the Florida Department of Transportation, the Florida Transportation Commission and private-sector transportation partners, who discuss issues important to Florida in an effort to develop high-quality roadway systems throughout the state.
