Florian Fessel, PhD

Florian specializes in market research for transit agencies with expertise in behavioral research of transit customers. He has conducted dozens of research projects related to attitudinal surveys, customer satisfaction studies, origin-destination studies, stated preference studies, focus groups, and qualitative research. In his role, he manages these projects from start to finish, including designing and developing methodologically sound surveys and experimental research, supervising the fielding effort, conducting statistical analyses, and communicating the results and implications. He has managed such projects for the Port Authority of New York & New Jersey, NY MTA, Chicago's RTA, Chicago Transit Authority, Pace Bus, Utah Transit Authority, Triangle Transit Authority, and Charlotte Area Transit System.

Outside of RSG, Florian enjoys exploring cities, eating out, and brushing up on his rudimentary French. He lives with his husband, Luke, and English Bulldog, Fritzi, in Burlington, Vermont.

Colin Smith

Colin leads RSG’s freight model development projects. He has worked in transportation planning since 1999, with an emphasis on using survey data, discrete choice models, and network modeling tools to understand aspects of travel behavior such as freight movement, long distance passenger travel, airport choice, and airport ground access; to model the greenhouse gas emissions from transportation; and to forecast demand for new transit services and highway capacity. Colin is currently engaged on projects for the Transportation Research Board, Federal Highway Administration, and various state departments of transportation and metropolitan planning organizations.

Prior to joining RSG in 2003, Colin worked for Symonds Group, Ltd. in London in the Transport Planning team, where he consulted on demand forecasting and transportation planning projects in the UK and Europe.

Colin lives in New Hampshire with his family and enjoys spending time with his kids, hiking, trail running, cycling, gardening, and gradually renovating his old house.

Michelle Lee, GISP, PMP

Michelle Lee leads RSG’s transportation behavior research work and has extensive experience managing statewide and regional household travel survey programs. Her background in geographic information systems (GIS) and global positioning system (GPS) technologies was essential to the development of RSG’s industry-leading smartphone-based GPS travel survey app, rMove™. Michelle applies logical thought processes to develop creative, data-driven solutions for RSG's clients.

Michelle has more than 20 years of project management experience. In that time, she has managed dozens of transportation, technology, survey, planning, environmental, health, and physical activity projects. Michelle began her career at the Center for Geographic Information Systems (CGIS) at Georgia Tech before transitioning to work for private sector consulting firms.

A graduate of Michigan State University, Michelle serves on the Alumni Advisory board for the MSU Department of Geography. She returned home to Florida in 2017 and currently resides on Florida’s Space Coast with her family. Michelle enjoys watching rockets launch and manatees swim from her backyard.

Margaret Campbell

Since joining RSG in 2004, Margaret has specialized in market research studies for transit agencies. She has significant expertise in onboard origin-destination studies, customer satisfaction studies, attitudinal surveys, qualitative research projects, and stated preference studies for agencies nationwide. Margaret has recently managed market research projects for NY MTA, Chicago’s RTA, Chicago Transit Authority, Metra, Pace Bus, Sound Transit, NJ TRANSIT, Northeast Corridor Commission, Utah Transit Authority, GoTriangle, and the Charlotte Area Transit System.

Prior to joining RSG, Margaret studied survey research methods and social psychology. She now strives to bring these methods and theories into practice on transit market research projects. Margaret’s expertise in survey methods, project management, and analytics allows her to design creative, cost effective, and methodologically sound studies that produce actionable results for her clients.

Margaret enjoys cooking and lives in Miami, Florida with her husband, daughter, and French Bulldog, Elmer.

Greg Spitz

Greg Spitz is a transportation economist, planner, and project manager with both domestic and international experience. His focus is researching transit using multiple types of transit surveys: origin-destination (O-D), stated preference (SP), customer satisfaction, and market analysis. From these surveys, he estimates demand models to create travel market forecasts. As part of his daily efforts, Greg manages projects, designs and develops surveys, moderates focus groups, conducts descriptive and multivariate statistical analyses, and reports and presents the results of his studies.

Greg has been interested in public transportation issues for a long time. His first attempt to make a living in the field was starting a bicycle rickshaw business in Chicago using Indonesian pedicabs. It was a fantastic job that paid the rent, provided plenty of exercise, and also left him some beer money. However, it didn't provide for much else (especially during Chicago's winters), so Greg looked for something more in the field of transportation.

Before joining RSG in 1996, Greg worked at Louis Berger International as an international transportation consultant on large infrastructure projects, primarily in Southeast Asia (where he traveled around again via Indonesian pedicabs, but this time as a passenger).

Thomas Adler, PhD

Thomas Adler is a founding leader of the RSG team and continues to guide the company through influential project work, innovative research and strategic direction. He has personally directed over 250 major projects and has more than 40 years of experience in developing and applying advanced models to client challenges. His project work ranges from feasibility studies for large infrastructure development, to marketing strategy studies for Global 100 companies, to detailed planning studies for both public and private sector initiatives.

Before cofounding RSG in 1986, Tom was a professor at Dartmouth College, teaching courses in consumer choice modeling, operations research, computer science, and engineering. He also served as director of the graduate program in resource policy at Dartmouth, and was the principal investigator for several large, federally-sponsored research projects. He continues this research today as principal investigator and task leader for six National Academies studies.

Tom enjoys skiing, skating, bicycling and hiking in Vermont and, with his wife of 40 years, visiting his three daughters (all management consultants, in London, New York, and Cambridge) and grandchildren.
