"Stockholm's congestion charge is working, new figures suggest. Traffic going through central Stockholm has been cut by 25 percent during the first half of the year."
"Wait times coming into the city have decreased by 33 percent during morning rush traffic and are 50 percent the size during the evening rush out of town, an analysis group appointed by Stockholm municipality has said."
"The effects on traffic safety are hard to analyze at this point due to the short period the tax has been in place, but analysts said the working environment for professional drivers such as bus, truck and taxi drivers in the city has improved."
