Define "traffic congestion."

Traffic congestion is characterized by a condition where vehicles experience slower speeds and increased queueing. This typically occurs when the volume of traffic exceeds the road's capacity, leading to congestion. Factors contributing to traffic congestion may include high traffic volumes, accidents, road construction, or adverse weather conditions.

Slower speeds during congestion can lead to significant delays for drivers and can also impact the safety and efficiency of transportation systems. Understanding this definition is crucial for traffic incident management as it highlights the need for responsive strategies to alleviate congestion and improve traffic flow. Recognizing the signs of congestion is a primary step in ensuring that traffic incidents are managed effectively to minimize their impact on travel times and overall roadway safety.
