This study intends to provide a thorough review of existing literature focusing on AV technologies, with respect to (1) the potential impacts of AVs on travel behavior and the transportation network; and (2) public perceptions toward AVs. Potential impacts of AVs were categorized into long-term impacts on location choices, urban development, and land use; mid-term lifestyle choices, such as auto ownership; and short-term daily travel choices, such as activity participation. Public perceptions can be viewed from several aspects, including technology adoption and willingness to pay, perceived benefits and concerns, and the perception of technologies. Besides discussing the trends in AV studies, several research gaps were recognized including the need for applying psychological models in perception analysis, taking advantage of advanced survey models like implicit association test instead of self-reporting surveys, and the necessity to use integrated land use and demand model with realistic assumptions to improve the predictions’ reliability.
