This intermodal center provides a possibility for various circulation types to intertwine with one another which I consider can be a possibility to animate the transit center with various activities, such as exhibition, food and shops. Thus, these attractive activities can encourage people to use public transportation more because of the interesting waiting time instead of a boring one. And an intertwining circulation system can provide more chance for people to view or participate in to those activities. At the same time, this transit center is organized by a background system including lighting and information technology. By using daylight as a timer to provide a general sense of time of a day and time of a year; by using information media, such as mobile phone, GPS, electronic screens, to provide exact ride guide for passengers who may take part in the activities inside the transit center; this intermodal center forms an environment which is attractive, flexible and convenient. The physical form of the transit center is generated based on the intertwining circulation system which means moving inside the building is a process of experience the interaction of different actions.
