Which of the following is not a traffic management method?

Open pathways are not typically classified as a traffic management method. Traffic management methods are designed to control the movement of vehicles and pedestrians, ensuring safety and efficiency in operations. A high impact barrier, gates, bollards, and temporary barriers all serve distinct roles in managing traffic flows, directing vehicle movement, and minimizing risks of collisions or accidents.

In contrast, open pathways suggest a more unrestricted form of movement, which can lead to confusion during loading or unloading operations, increase the risk of accidents, and compromise safety. Effective traffic management is contingent upon structured systems that guide and control movement rather than leaving areas open without defined pathways. This distinction underlines why open pathways do not fit within the typical scope of traffic management methods.
