Abstract:This research project was focused on the transportation planning implications of automated/connected
vehicles (AV/CVs) on Texas highways. The research assessed how these potentially transformative
technologies can be included in transportation planning to assist the decision-making process. Researchers
completed seven tasks for the project. First, the research team briefly defined existing AV/CV technologies
and explored future technologies by conducting a literature review and drawing upon previous research.
Next, the research team examined potential changes that AV/CVs may have on travel behavior, urban form,
and other aspects of the transportation system. The research team also studied the potential effects of
automation on commercial vehicle transportation and freight. The research study analyzed how travel
modeling could be affected by AV/CVs and conducted some experimental model runs using a trip-based
model from the Austin, Texas, region. The project also included a statewide web-based behavioral
preferences survey and a series of three stakeholder workshops held in spring 2016. Based on the study
findings, this report presents the potential changes to the transportation planning process needed to address
AV/CV technology and inform the decision-making process, despite the many uncertainties about how
AV/CVs will impact the transportation system.
