A lateral buffer space serves as a critical safety measure in work zone temporary traffic control by creating a physical separation between the traffic space—where vehicles move—and the work space, where construction or maintenance activities occur. This buffer enhances safety by reducing the risk of vehicle intrusion into areas where workers are present. By ensuring there is a designated space between moving traffic and active work areas, the buffer helps prevent accidents, allowing both traffic and construction operations to proceed more safely.

In this context, differentiating between the traffic space and other areas such as the work zone or pedestrian zones is essential. While the work zone is where the activity takes place and the pedestrian area is designated for foot traffic, the buffering primarily focuses on separating vehicular movement from the workers to minimize hazards. This understanding of buffer space highlights its importance in traffic management and work zone safety.
