Venigalla for his patience, motivation, and continuous support throughout my Ph.D. study. His guidance helped me to improve my technical writing skills, made me think innovatively and turned me into a real researcher. I would also like to thank rest of the dissertation committee members: Dr. Shanjiang Zhu for his help in the design of the survey questionnaire and other technical aspects of the research study, Dr. Behzad Esmaeili for his kindness, thoughtful and invaluable feedback, Dr. Rajesh Ganesan for his insightful comments and suggestions throughout my Ph.D. I gratefully acknowledge the funding sources that made my Ph.D. work possible. I was funded from the research grant from the Office of Provost at George Mason University for three consecutive summers. I am indebted to Sid and Reva Dewberry Department of Civil, Environmental and Infrastructure Engineering for funding me for three consecutive years during my research study. Also, partial funding of the research was obtained from District Department of Transportation and US Department of Transportation’s University Transportation Centers research program. I would like to express my gratitude to the project panel at the District Department of Transportation, especially to Ms. Kimberly Lucas, Ms. Stephenie Dock, and Dr. Stefanie Brodie for their invaluable guidance, input, and support. My time at Mason was made more enjoyable due to my friends who became part of my life. I will always cherish my memories I spent with them for the rest of my life. I would also like to thank all the undergraduate and graduate students who helped me in the collection of survey data at various bikeshare stations. I am very much indebted to my loving husband Surya, who supported me in every possible way to see the completion of this work. Lastly, I would like to thank my parents and brother who trusted and supported me in all my pursuits. iii TABLE OF CONTENTS Page List of Tables
