In transportation engineering, which section in the AASHTO Green Book discusses median openings?

• A. Sec. 9.6.2
• B. Sec. 9.6.3
• C. Sec. 9.8.4
• D. Sec. 9.7

Answer: (C)

In the AASHTO Green Book, section 9.8.4 specifically addresses median openings. This section provides guidelines and criteria for the design of median openings, including their location, dimensions, and the necessary traffic control measures. Median openings are critical for facilitating safe and efficient vehicular movements and are designed to accommodate turning movements, both for left turns into and out of adjacent properties, and for pedestrians crossing the road. Understanding the regulatory context and design principles highlighted in this section is essential for ensuring that engineers can effectively integrate median openings into roadway designs, as well as for promoting traffic safety and operational efficiency. The other sections mentioned do not focus specifically on median openings, which distinguishes section 9.8.4 as the correct reference for this topic.
