Tomtom Says Los Angeles is the Most Congested City in the US

Report indexes the 59 worst major cities in the US for traffic congestion

Navigation company Tomtom has been allowing owners of its GPS units to opt into sharing their driving data since 2011 and published its first congestion index in the first quarter of 2012. It just released its survey for all of 2012 and found that Los Angeles had the worst traffic congestion in the US last year. 

Tomtom uses the data that comes from drivers to find out how much time it takes to drive in cities given optimal situations and in traffic at various times of the day. It uses the data to find how much time as a percentage is added to a journey during congested periods.

For Los Angeles, Tomtom found that the average congestion adds 33% to the average journey. So for a journey that could take an hour in optimal conditions, the average traffic congestion adds 33 minutes to the journey. At peak times, it adds 39 minutes for each hour driven. That means that drivers will spend more time sitting in traffic in an hour at peak congestion than actually driving. For drivers with a 30-minute commute, they will waste 90 hours in traffic. 

Average congestion in North America ticked up slightly to 18%, which is about 1% worse than at the beginning of the year. 

If you want to see where your city ranks whether you live in North America, Europe, Australia or Africa, you can view Tomtom's index here
