HOV lanes reduce traffic and cut costs, right? Not always, economists find
A team of researchers conducted a study on measuring traffic speed at the University of Colorado at Boulder (Thomas, 2019). The team measured traffic speed using various methods, including GPS devices and smartphones. They found that traffic speeds vary depending on the day and week, where traffic is typically slower during rush hour and on weekends. The study also found that traffic speeds vary by location; for example, traffic is typically slower in urban areas than in rural areas. The team planned to study traffic patterns to develop more efficient ways to manage traffic flow.
