What was once a futuristic concept, often associated with pop culture, is not only possible, but is coming very soon to a roadway near you. Autonomous cars are precisely what the term “disruptive technology” describes. It is technology that will fundamentally change much of what we know about personal transportation—changing our habits, our preferences, and our opportunities, and nothing will be more impacted by these changes than our cities. As city planners, we must be on the forefront of understanding this technology and how we can prepare for the potential impacts. This presentation will include modeled scenarios for potential impacts to roadway networks, neighborhood development, and site design. Specific planning tasks such as comprehensive planning and zoning code revisions will be discussed as well, as they will be instrumental in preparing for, and adapting to, this emerging technology.
