The Geometry Chapter outlines essential considerations for the physical layout of streets to ensure they are safe, accessible, and resilient. Designers must evaluate how geometric elements like lane widths, curb radii, and sidewalk configurations affect safety, stormwater management, and mobility. The chapter emphasizes the need for careful planning around roadway design, vehicle movement analysis, drainage, pedestrian access, sustainability, and unique street conditions such as complex intersections or step streets. Geometric design should balance the needs of all users while aligning with DOT policies and Vision Zero goals.
