Generally speaking, buses are the most common form of mass transportation. The development of urbanization and motorization has caused the urban population and area to continue to increase, and the demand for public transportation has increased rapidly, requiring public transportation companies to invest more passenger cars.

According to the statistics of 0.6 vehicles per 10,000 urban population, there are currently about 264,000 urban passenger cars, and they will reach at least 630,000 by 2010, with an average annual increase of at least 3~ 40,000 vehicles, including scrapping and renewal, an average of 55,000 vehicles per year. Buses are mostly used to meet the needs of grassroots people to commute to and from get off work. The low price creates a good means of transportation for ordinary people to work.
