Transportation practitioners have the power and obligation to incorporate the voices of their communities in transportation decision-making. The U.S. Department of Transportation (DOT) developed Promising Practices for Meaningful Public Involvement in Transportation Decision-Making to help funding recipients meaningfully involve the public in various stages of transportation decision-making and build their organizational capacity to do so. Public involvement from the beginning and throughout a project’s lifecycle has the potential to help projects come to life faster and to better meet the needs of the community. This set of promising practices provides a shared definition of meaningful public involvement and promising practices to help address barriers to inclusion in transportation decision-making. DOT released version 2 of the meaningful public involvement guide on November 8, 2023.
