What is the purpose of table 6E-1 in traffic control?

The correct choice highlights that table 6E-1 serves to specify buffer space requirements for work zones. In traffic control, establishing a buffer zone is crucial to ensure the safety of both workers and the motoring public by creating a physical separation between the activity taking place and the vehicles in transit. This space helps reduce the risk of accidents by providing a designated area where drivers can anticipate changes in traffic flow, thereby enhancing overall safety in construction or maintenance zones.

The specific dimensions and guidelines provided in table 6E-1 are designed to align with national safety standards, which are essential for effective traffic management in work zones. By ensuring appropriate buffer zones, traffic control plans mitigate potential hazards that could arise from close proximity between work activities and moving traffic.
