What is the main purpose of a longitudinal buffer space?

Answer: B — To minimize worker exposure to traffic

The primary function of a longitudinal buffer space is to minimize worker exposure to traffic. This safety measure is essential in work zones where construction or maintenance activities occur alongside active traffic. By creating a designated area between moving vehicles and the workers, the longitudinal buffer reduces the risk of accidents and injuries. Utilizing a buffer space helps maintain a safe distance that protects personnel from the hazards of nearby traffic, enabling them to perform their tasks more securely. While space considerations and aesthetic values may hold significance in other contexts, the fundamental goal of the longitudinal buffer is always aimed at enhancing safety for workers on site.
