Traffic Meaning

Traffic on roads may include pedestrians, ridden or herded animals, vehicles, streetcars and other conveyances, either singly or together, while adopting the public way for purposes of travel. Traffic laws are the laws which rules traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have advanced over time to facilitate the orderly and timely flow of traffic.
Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections.
Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often categorized by type: heavy motor vehicle (e.g., car, truck); other vehicle (e.g., moped, bicycle); and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' discretion and the zeal to cooperate.
Organization typically creates a better combination of travel safety and efficiency. Events which disrupt the flow and may cause traffic to degenerate into a disorganized mess include: road construction, collisions and debris in the roadway. On particularly busy freeways, a minor disturbance may continue in a phenomenon known as traffic waves. A complete breakdown of organization may lead to traffic jams and gridlock. Simulations of organized traffic frequently involve queuing theory, stochastic processes and equations of mathematical physics applied to traffic flow.
