Many of the same places have extensive, although not always well maintained or efficiently operated, transit and Commuter Rail systems. Ridership has plateaued or declined on many of these systems, highlighting their currently limited attractiveness as a modal choice. Metropolitan Boston serves as a case study into what measures would be effective in inducing a meaningful level of mode shift from automobiles to rapid transit (rail) options. In 2019 four new reports identified Metro Boston as having some of the most congested roads in the nation. Motorists nevertheless continue to drive on these highly congested roads while a developed Commuter Rail, subway and bus transit system exist across the region. This thesis uses a standardized online questionnaire distributed to motorists across Massachusetts and Rhode Island to understand individual attitudes toward mode shift, and specifically using Rapid Transit instead of driving for their regular daily commute. It targets motorists on the 10 most congested corridors in Massachusetts. 402 completed questionnaires were received from ZIP Codes across Massachusetts and Rhode Island revealing individuals’ attitudes and feelings towards shifting to transit for their commute. Specific demographic considerations, other than geographical spread and origin and destination data, were not considered in this study. The findings indicate that the high level of free or subsidized parking provided across the study area draws Metro Boston commuters away from transit and that 63.7% of respondents would consider shifting to Rapid Transit if the cost of driving went up substantially (50% higher cost). Respondents further indicated that access & network limitations of the MBTA rail transit system, travel time by transit combination (including all legs of the trip), the transit system reliability, frequency of trains on a number of Commuter Rail routes and relatively high fare prices are considered factors preventing significant mode shift to transit.

I wish too to thank Dr. Anson Stewart, the senior reader of this thesis for making countless useful comments, suggestions and improvements to the research and writing, particularly with software choice and usage. I also wish to thank readers Professor Jinhua Zhao and the indomitable Fred Salvucci, former Massachusetts Transportation Secretary for giving input on readings, on the results and further areas for research. My thanks to the Jen Greenleaf, Kai Smith and the Rotch and MIT Interlibrary Loan staff for their assistance in finding texts and journals. Outside of the MIT family I wish to also acknowledge the help and assistance of the Central Transportation Planning Staff of the Boston Region Metropolitan Planning Organization for their assistance with data, advice and access to their reports. Finally I wish to thank the friends, family and classmates who have supported me in this endeavor. 3 Contents List of Figures ............................................................................................................................ 5 List of Tables .............................................................................................................................. 6 Terms and Definitions ............................................................................................................... 7 1.
