Sacramento-area roadways ranked among nation’s most congested

Five highway sections in the Sacramento metropolitan area ranked among the worst in the nation in terms of traffic congestion, according to a recent study.

The 2015 Traffic Scorecard prepared by INRIX, a firm specializing in transportation analytics, was released Tuesday and is based on an analysis of the most congested corridors in select countries in Europe and the United States by metropolitan area for the year.

In the Sacramento-Arden Arcade-Roseville area, the section of Capital City Freeway, or Business 80, between P Street and Fulton Avenue, was the worst in the region and ranked 75th among most congested corridors in the United States. The worst peak period was the afternoon commute, with a peak travel time of 11 minutes and peak average speed of 38 mph. The worst congestion during that period was at 5 p.m. on Thursday, with a travel time of 23 minutes for the 7.24-mile stretch at a speed of 19 mph.

The region’s second-worst corridor was Interstate 80 from El Camino Avenue to Capitol Avenue/Enterprise Boulevard. It was followed by Interstate 80 from Sierra College Boulevard to Douglas Boulevard; Interstate 80 from I-5/Highway 99 to Northgate Boulevard; and Highway 99 from Fruitridge Road to Mack Road/Bruceville Road.

Nationwide, Los Angeles, Washington, D.C., San Francisco, Houston, New York and Seattle ranked as the most congested cities in the United States, where commuters spend a total of 8 billion hours stuck in traffic in 2015, according to the report.

The United States accounts for 50 percent of the top 10 metropolitan areas with the worst traffic congestion across the United States and Europe. Only London had worse traffic than the top-ranked U.S. cities.

Analysts said congestion is fueled by continued economic and population growth, higher employment rates and declining gas prices. Cities that experienced the most economic improvement during the past year are at higher risk for consequences related to worsened traffic conditions, including reduced productivity, high emissions and increased stress levels, the report says.
