Answer: (B)

The recommended lane width for a typical intersection scenario according to AASHTO is 11 feet. This standard is based on safety and operational performance considerations, as lane widths directly impact vehicle maneuverability, stability, and safety. A lane width of 11 feet provides adequate space for various types of vehicles, including larger ones like trucks, while also promoting efficient traffic flow and reducing the potential for accidents. The guideline acknowledges that wider lanes can enhance the perception of safety for drivers, especially in busy intersection environments. Ultimately, the choice of 11 feet reflects a balance between functionality and safety, contributing to more effective traffic management in urban and rural settings alike.
