Today, in China, with the development of technology, cars can be affordable by people. However, the pressure on roads and limited space results in the traffic jams. These traffic jams can sometimes even go up to two hundred and fifty kilometers. There are various methods to create more space to avoid traffic jams. Some of the methods presently used by the government are using flyovers, underpasses and directing the traffic in a single direction.
