Measuring progress. Inspiring action.


Waiting in traffic is frustrating, and also increases air pollution and costs — especially for businesses moving freight. While traffic congestion can result from otherwise positive trends, like a booming economy, it is also the case that transportation systems can be designed and managed in ways that result in lower levels of congestion for the same amount of traffic. Congestion can be impacted by factors ranging from road capacity to prevalence of alternate forms of transportation, including mass transit and biking. Although measurement is limited to major metropolitan areas, congestion in metropolitan areas ultimately impacts the movement of goods and people throughout the state.
