Traffic congestion is a condition on convey networks that occurs as use increases, and is characterized by more gradual speeds, longer trip times, and incremented vehicular queueing. The most mundane example is the physical utilization of roads by conveyances. When traffic demand is great enough that the interaction between conveyances slows the haste of the traffic stream, this results in some congestion. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When conveyances are plenarily ceased for periods of time, this is colloquially kenned as a traffic jam or traffic snarl-up. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage.

Traffic congestion has a number of negative effects:
• Wasting time of motorists and passengers ("opportunity cost"). As a non-productive activity for most people, congestion reduces regional economic health.
• Delays, which may result in tardy advent for employment, meetings, and edification, resulting in lost business, disciplinary action or other personal losses.
• Inability to forecast peregrinate time accurately, leading to drivers allocating more time to peregrinate "just in case", and less time on productive activities.
• Wasted fuel incrementing air pollution and carbon dioxide emissions owing to incremented idling, expedition and braking.
• Wear and tear on conveyances as a result of idling in traffic and frequent expedition and braking, leading to more frequent repairs and supersessions.
• Stressed and frustrated motorists, emboldening road rage and reduced health of motorists
• Emergencies: blocked traffic may interfere with the passage of emergency conveyances peregrinating to their destinations where they are exigently
