Appendix C Peer Review Panel Biographies
Richard E. Walker is the manager for the Modeling and Forecasting Division at Metro Portland, the MPO for Portland, Oregon. He manages all programs related to travel forecasting: including data collection, model development, and model applications. His areas of expertise include multimodal, freight, transit, and air quality conformity modeling. He has previously participated in the peer review of metropolitan travel forecasting models in Santa Cruz, Salt Lake City, Las Vegas, Anchorage, Phoenix, and Philadelphia. In Oregon, Mr. Walker is a past chair of the statewide Modeling Steering Committee and the Modeling Program Coordination Committee. As a recipient of a BS degree in civil engineering from Montana State University, he has been a member of the modeling profession for over 35 years.
Elizabeth Sall is the Deputy Director for Technology Services at the San Francisco County Transportation Authority. She has previously worked as a consultant for various travel analysis studies around the country. She has a B.S. and M.S. in Civil Engineering from North Carolina State University and the University of Texas at Austin, respectively. Her research interests include integrated dynamic network modeling and representing alternative transit service and non-motorized modes in travel models. Elizabeth has been active in a variety of Transportation Research Board committees and currently serves on the Planning Applications and Metropolitan Policy and Practices standing committees.
Chris Johnson is a principal planner at the PSRC responsible for the development and improvement of the regional travel demand models. He has a BS and MS in Urban and Regional Planning from the University of Wisconsin. He has over 18 years of modeling experience in the public and private sectors and has completed projects in several states. He is currently leading the PSRC's transition from a trip-based to an activity-based travel demand model. In total, development and deployment of the activity-based model will span 4 to 5 years and have a consultant budget of nearly $1 million.
Michael Mahut is a Senior Scientist at INRO Consultants, where he leads the company's research on dynamic traffic assignment (DTA) and traffic simulation, as well as providing modeling expertise on consulting projects involving the application and calibration of simulation-based DTA. Michael has a doctoral degree in Operations Research and Computer Science from the University of Montreal, and is an associate member of the Interuniversity Research Centre on Enterprise Networks, Logistics and Transportation (CIRRELT). Michael is also an active member of the TRB committees on Network Modeling and Traffic Flow Theory and Characteristics.
Stacey Bricka, Ph.D., is a Research Scientist with the Texas A&M Transportation Institute. Her research focuses on all aspects of travel behavior, travel survey methods, and the application of survey data to travel demand modeling and emerging uses, such as understanding long distance travel and electric vehicle usage. She has more than 20 years of experience in designing, conducting and analyzing travel surveys, having managed travel surveys in more than 35 metropolitan regions across the country, including the 1998 TRPC survey. She is an experienced user of the National Household Travel Survey data series, and currently serves as chair of the TRB Task Force on Understanding New Directions for the National Household Travel Survey. She is a member of the TRB Committees on Travel Survey Methods and Travel Demand Forecasting.
