What is the general term for pedestrians, animals, vehicles, and other conveyances using a highway?

The term "traffic" encompasses all pedestrians, animals, vehicles, and other conveyances that utilize a highway. It is a broad and established term in transportation and road safety contexts, referring not only to motor vehicles but also to any individuals or entities that move across roadways. Understanding the concept of traffic is crucial for law enforcement and public safety, as it defines the interactions and potential hazards present on the roads.

Other terms, like "movement" or "flow," might refer to how these groups move along the highway but do not encapsulate all entities participating in that movement in the way that "traffic" does. "Road use" might imply the act of using the road, but it does not adequately describe the collective presence of all types of users on the highway.
