Congestion refers to a condition in which the flow of something, such as traffic, air, or fluid, is blocked or severely restricted. In the context of transportation, congestion usually refers to heavy traffic or a buildup of vehicles on roads or highways, which can lead to delays, increased travel times, and frustration for drivers. Congestion can also occur in other contexts, such as crowded or overcrowded areas, crowded public spaces, or congested telecommunications networks.
