This paper analyzes the queuing problem that was experienced during the Shanghai World Expo of 2010. The queuing problem will be discussed at three levels. The three levels include the physical, psychological, and social aspects of the queuing problem. The collective behavior of visitors is studied through analyzing the information from the different sources, such as, the network of electronic eyes, the evaluation platform based on mobile phone system and the Internet. A hybrid information network technology is implemented. Based on the Wuli-Shili-Renli (WSR) system methodology, a new theoretical analysis framework for the queuing problem is proposed.
