In 2004, it was rated as the country's third-worst traffic bottleneck, with approximately 400,000 vehicles using it per day. [3] [4] In a 2010 study of freight congestion (truck speed and travel time), the U.S. Department of Transportation ranked this section of I-290 as having the worst congestion in the United States.

Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s, resulting in many of the roads becoming obsolete. [2]
A traffic bottleneck is a localized disruption of vehicular traffic on a street, road, or highway. As opposed to a traffic jam, a bottleneck is a result of a specific physical condition, often the design of the road, badly timed traffic lights, or sharp curves. They can also be caused by temporary situations, such as vehicular accidents.

A bustling shopping district in Chicago known as the “Mexico of the Midwest” has seen foot traffic plummet by 50% — as residents say they fear the immigration raids promised by President Trump.
Also, traffic flow and speed sensors are used to detect problems and alert operators, so that the cause of the congestion can be determined, and measures can be taken to minimize delays. These systems are collectively called intelligent transportation systems.
In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.
