The urban transportation of Xian has been developed rapidly in recent years. The second ring road, third ring road and freeway-ring around the city have all been completed and put into service. The city buses and suburban buses can bring you to every corner of the city. Also, to meet the development of the tourism industry, tourist special buses and sightseeing buses are now operating. Although traffic congestion happens now and then, it is much better than that of Beijing and Shanghai. The local government also does a lot to relieve the traffic pressure, including widening roads, building pedestrian overpasses and running inter-zone buses, etc.
