For minimum turning paths, which figures in the AASHTO Green Book should be referenced?

For minimum turning paths, which figures in the AASHTO Green Book should be referenced?

• A. Figures 2-1 through 2-5
• B. Figures 2-10 through 2-32
• C. Figures 3-50 through 3-70
• D. Figures 4-20 through 4-40

Answer: (B)

The correct reference for minimum turning paths in the AASHTO Green Book is indeed found in the specified range of figures. These figures present detailed information about turning path radii and dimensions for different vehicle types, which are critical for designing intersections and determining how vehicles navigate through them. Figures 2-10 through 2-32 specifically address various aspects of geometric design related to vehicle maneuverability. They provide turning templates that allow engineers to visualize and assess the adequacy of design to accommodate various vehicle classes. Understanding these figures is essential for ensuring that road designs facilitate safe and efficient vehicular movement, especially in urban environments and at intersections. In contrast, the other figure ranges mentioned focus on different aspects of roadway design, which are not directly related to minimum turning paths. This distinction emphasizes the importance of consulting the appropriate figures for specific design criteria in the roadway design process.
