This study aims to enhance understanding of the impact of new and emerging technologies on travel behavior/demand for the state of Georgia, and, thus, potentially contribute to improving transportation planning and demand forecasting for Georgia residents. In this project, the research team designed and implemented a wide-ranging travel survey that explores people’s opinions about travel-related issues, together with how they use new mobility technologies and services, and travel in general. The study employed two sampling frames: (1) address-based stratified randomly sampled households, and (2) Georgia residents who participated in the 2017 National Household Travel Survey (NHTS) and agreed to be contacted for further surveys. The data were collected across about six months. The study explores five main themes: general travel behaviors, commute and work patterns, general opinions and attitudes, new and emerging technologies and services, and future transportation, with a specific focus on autonomous vehicles. Some findings include: despite the low levels of current ownership of alternative- fuel vehicles (2.2% of primary vehicles are hybrid/electric), respondents exhibit considerable interest in having such vehicles (59%); more than 5% “commute” by working at home, compared to 3% who use transit; overall, ridehailing services seem to have more substitution effects than complementarity and generation effects, including both car-for-car substitution and net reductions in the use of active transportation and public transit modes; and half of respondents (51%) said they are likely or very likely to own a self-driving car, whereas 27% and 12% are likely or very likely to use a driverless taxi alone/with others and with strangers, respectively. Based on results, the study provides some implications for policy.
