U.S.C. – United States Code
SAFETEA-LU establishes that MPOs “to the maximum extent practicable, employ visualization techniques to describe plans.” (Source: SAFETEA-LU, Public Law 109-59) The Federal Highway Administration
(FHWA) and Federal Transit Administration (FTA) have jointly issued rules for MPOs to follow in order to meet the requirements established in SAFETEALU. The FHWA and FTA define “visualization
techniques” as “methods employed by states and MPOs in the development of transportation plans and programs with the public, elected officials, and other stakeholders in a clear and easily accessible format.” This is intended to “promote improved understanding of existing or proposed transportation plans and programs.” The FHWA and FTA language is intentionally vague in regards to the types of visualizations that are appropriate or expected. As a result, each MPO is allowed the flexibility to meet visualization requirements in a way that most “appropriately illustrates the projects or plans.” Samples of visualization techniques range from photo, PowerPoint or video presentations, brainstorming sketches and visual preference surveys to scale models, renderings, maps, aerials, 3-D imagery and other computer-aided visualization.
