The park itself is the setting for Olympic training grounds as well as numerous cultural, recreational and leisure activities. Buildings are partially hidden behind hills or woods to create an ecological environment that places man and nature in harmony. Seven groups of buildings are arranged similarly to the stars in the Big Dipper, and when illuminated, the buildings point to a circular island on the axis line in the northern part of the lake. The tower is organized into two parts and houses the trade center headquarters as well as the development s primary hotel. Standing north on the axis line beyond the tower is an open plaza and the Chinese International Exhibition Center, an arcing transparent structure which connects the inner city with the outskirts and marks the symbolic city border.
Vehicular traffic is confined to perimeter roadways wherever possible.
The ring road surrounding the central park is limited to pedestrians, bicycles and internal public transportation. Underground transit stations, located at the north and south end of the park are combined with city and internal shuttle bus stops, and also connect to the automated people moving system. Perimeter lots offer exhibition center parking. Semi-sunken parking lots along the edges of the athletes village are accessed via perimeter roads. Within the sports complex, vehicular traffic is managed through a series of slightly depressed service roads and ringways that bring people to drop off points at each of the stadiums and sports facilities.
