Synopsis: Visualization methods have long been integral to the public involvement process for transportation planning and project development. From well-established methods such as conceptual sketches or photo simulations to the latest immersive technologies, state departments of transportation (DOTs) recognize that visualizations can significantly increase public understanding of a project’s appearance and physical impacts. Emerging methods such as interactive three-dimensional environments, virtual reality, and augmented reality can dramatically enhance public understanding of transportation options and design concepts. NCHRP Synthesis 632: Visualization for Public Involvement, from TRB’s National Cooperative Highway Research Program, documents state DOT practices of visualization for public involvement throughout the life cycle of plans, programs, and projects.
