Which chapter contains information on intersection geometry in the AASHTO Green Book?

• A. Chapter 5
• B. Chapter 8
• C. Chapter 9
• D. Chapter 10

Answer: (C)

The correct answer identifies Chapter 9 of the AASHTO Green Book as the section that covers intersection geometry. This chapter delves into various aspects of intersection design, including the necessary geometric considerations for ensuring safe and efficient vehicle movements. Key elements discussed include the types of intersections, sight distance requirements, turning radii, lane widths, and the overall arrangement of the intersection elements.

Chapter 9 primarily focuses on addressing the complexities of intersection design to accommodate different traffic volumes and types of road users, which is crucial for enhancing intersection safety and functionality. The information provided in this chapter aids engineers in developing effective design solutions that promote better traffic flow and reduce the likelihood of collisions at intersections. Understanding these geometric principles is essential for anyone involved in transportation engineering and planning.
