Which chapter and table in the AASHTO Green Book provides details on vehicle sizes?

• A. Chapter 1, Table 1-2
• B. Chapter 2, Table 2-4a
• C. Chapter 3, Table 3-5
• D. Chapter 4, Table 4-8

Answer: (B)

The AASHTO Green Book is a key reference for highway geometric design and provides valuable guidelines regarding vehicle sizes used in transportation planning and design. The specific details about vehicle sizes are found in Chapter 2, specifically in Table 2-4a. This table outlines the design vehicle parameters, which include important dimensions and turning radii that influence the geometric design of roads and intersections. Understanding the vehicle dimensions is crucial for ensuring that highway infrastructure can accommodate a variety of vehicles safely and efficiently. This information is used by engineers to design roadways that facilitate the movement of both large and small vehicles, helping to reduce the risk of accidents and improve traffic flow. Other chapters and tables in the Green Book focus on different topics related to highway design. While they may provide useful information, they do not specifically address vehicle sizes as comprehensively as Chapter 2, Table 2-4a does. Thus, selecting this option is essential for anyone looking to understand the vehicle design requirements laid out by AASHTO.
