America’s 75 Worst Commutes: Highways to Hell.

They are the highways to hell in the country’s most gridlocked cities. The Daily Beast crunches the numbers to determine your ultimate morning nightmares. How did your commute rank?

Our first step was ranking the metropolitan areas with the worst rush-hour congestion. The order is based on the peak hour Travel Time Index (TTI) for the metropolitan area each highway is in. TTI is a measure of how much longer it takes to complete a road journey during peak congestion hours compared to free-flow hours. (Peak hours are defined as 6 a.m. to 10a.m., and 3 p.m. to 7 p.m.) Speeds during non-peak hours are used by INRIX to establish this free-flow baseline.

After determining the 75 worst metro areas, we then found the worst highway in each, defined as the most hours of bottleneck congestion, as reported by INRIX. The rankings then provide a still deeper look—at the most congested bottleneck segment for the worst highway in each area.


Three "winners" are from New York State.
