Different transportation organizations have collected various data related to walk and bike trips. However, few studies have investigated various aspects of walk and bike trips among different races and different household income groups. The main goal of this study is to explore the number of walk trips, number of walk trips for exercise, number of bike trips, number of bike trips for exercise, and bike share program usage among different household income groups and different races. To conduct the statistical analysis, the research team used the latest National Household Travel Survey (NHTS) dataset, which is the largest and the most valid national transportation-related dataset in the United States. The novelties of this study are to investigate the newly walk-related and bike-related attributes in the 2017 NHTS, and focus on different household income groups and different races. The primary contribution of this study is to provide a deeper insight into bike-travel and bike-travel behavior among different household income groups and different races in the U.S., which can assist the authorities and transportation planners in prioritizing investment in bike infrastructure. |
