The purpose of this study is to visualize the pedestrian crossing with Intersecting Solid Model. In this model, a circle around the location of pedestrian which represents personal area, is connected to other circles along time. The solid which is intersected between the model indicates pedestrian crossing, so we define it "Intersecting Solid". The pedestrian crossing, which is hard to express with 2-dimentional model can be easily expressed with this model. On the computer, we can construct a virtual 3D space and see the model rotating freely and interactively. We can understand the construction of pedestrian crossing.
