The Golden Week refers to a consecutive seven-day national holiday. In 1999, China started to carry out the Golden Week policy. Since then, the Golden Week has enriched people's daily life and promoted the development of social economy by encouraging people to travel and spend. Nevertheless, there is no denying that the problems caused by the Golden Week are getting obvious, such as the traffic jams, overcrowded tourist spots and rising prices. In 2012,the Chinese government announced that expressways nationwide would be toll-free during important holidays, including the two seven-day holidays around the Spring Festival and the National Day, which, to some degree led to the highly increased number of vehicles and people going out.
