The overall Congestion Level for all the North American cities analyzed between April and June 2012 is 21%.

“This Congestion Index gives the general public, businesses, industry and policy makers accurate and unbiased information about congestion levels in urban areas,” said Ralf-Peter Schäfer, Head of Traffic at TomTom. “Because TomTom’s traffic information is so precise, we can pinpoint congestion trouble spots more effectively. When combined with real-time traffic information and routing technology, traffic starts to be routed away from these congested areas, helping to ease congestion in cities and urban areas.”
