The table below shows data illustrating the best and worst days to drive in 100 core-based statistical areas, as defined by the federal government, during peak morning and afternoon hours from May 2011 to May 2012. Figures represent the delay, in minutes, for a one-way trip taking 30 minutes with no traffic congestion.

Totals, compiled by traffic research firm Inrix for Governing, measure average traffic delays across entire metropolitan regions. Those with longer commutes along major corridors will likely experience longer delays during peak periods than those with shorter, local commutes.

Inrix collects data via mobile application, GPS systems in personal and commercial vehicles and road sensors. Figures listed reflect average delays for all types of roadways: arterial roads, highways and city streets, etc.

Our map shows areas with the most congested Friday afternoon commutes.
