In order to obtain useful data for computer simulations of crowd flow in stations, we conducted surveys of upward crowds on stairs in real stations. We obtain detailed time series data of numbers, crowd flow coefficients, and walking speeds of people on stairs and confirm following 4 points quantitatively. 1. Crowd flow on stairs change from “unstable state” to “stable state” and “decreasing state”. 2. On narrow stairs, “unstable state” quickly disappears, and moves to “stable state”. 3. Crowd flow coefficients reach its peak and keep a stable value. 4. Walking speeds are almost constant during “stable state”.
