Moscow is the most congested city, with a peak hour index of 126. This means that the average 30 minute trip in free flow conditions will take 68 minutes during peak hours. Moscow has a limited freeway system, but its ambitious plans could relieve congestion. The city has undertaken a huge geographical expansion program, with the intention of relocating many jobs to outside the primary ring road. This dispersion of employment, if supported by sufficient road infrastructure could lead to improved traffic conditions.
