This Blueprint outlines a vision for cities in a future where automated transportation is both accepted and widespread as part of the built environment. It is a human-centered vision for the potential of city streets, intersections, and networks-one in which automation is harnessed to serve the goals of safety, equity, public health, and sustainability. As a vision, it sets out to inspire policymakers and practitioners to challenge basic assumptions of design, traffic operations, and engineering and to project a vision that builds on present progress, yet takes advantage of technological possibilities.
