Los Angeles ranked No. 1 on a list of cities with the worst traffic congestion. The study was done by traffic monitoring group INRIX.
The report says the worst Southland freeway is the 405 Freeway (pictured). Next is the heavily traveled 10 Freeway, the 91 Freeway in the Inland Empire, and then the 5 Freeway. The worst times to drive are Tuesday morning and Friday afternoon.
The study says the reason for the traffic is that the improving economy has more people out on the road.
