AP Interactive: Gridlock in America

The Associated Press released a study showing the crisis of traffic congestion and gridlock in metropolitan and urban areas.

The following links include interactive maps and data outlining the gridlock.

The Census Commuter Trends 2013
spreadsheet shows commuter population estimates and average commute times from 2013 for metropolitan areas across the country. This data is the most recently available from the U.S. Census American Community Survey.

The Population Projections shows total populations for micropolitan and metropolitan statistical areas. In addition to 2010 population counts, it provides population projections for 2015 and 2020.

The Vehicle Miles Traveled (VMT) file contains information on the extent of roadways and how heavily they are traveled within urbanized areas with 50,000 or more people. The spreadsheet includes vehicular travel data for two years — 2010 and 2013 — based on source data from the Federal Highway Administration (FHWA) .

Per capita figures for daily VMT should be calculated using the Census Bureau’s Population and Land Area Changes file , which provides figures on population and geography shifts in urbanized areas between 2000 and 2010.

The AP also built an interactive website which allows you to calculate your commute in metropolitan areas. You can visit that website by clicking here.
