Abstract: This study sought to document existing knowledge and practice on curb extensions, including permanent, tactical, and tactical curb extensions with mural art. First, we distributed a survey to agencies installing various types of curb extensions. Then we conducted a review of literature on permanent curb extensions, tactical curb extensions (with flex posts and paint) and tactical curb extensions with mural art. This included both published journal papers and project reports, and evaluations conducted by the agencies (or community partners). In our scan we found that most agencies have installed permanent (89%) and tactical (83%) curb extensions, while about half (54%) have installed curb extensions with mural art. Consistently, the reasons stated for installing curb extensions related to reducing motorist speeds, improving safety, reducing pedestrian crossing lengths, and increasing visibility. For tactical curb extensions, low-costs and the ability to quickly build and test installations were commonly cited. For tactical curb extensions with mural art, improving aesthetics and community livability through the addition of art were frequently mentioned. While the existing agency reports generally find positive results, such as increased vehicle yielding, reduced speeds, and reductions in pedestrian crossing distance and time, there are still very few rigorous studies of safety and curb extensions, particularly across multiple contexts or jurisdictions.
