This study aims to elucidate the anticipation factor in a street with uphill stairs. The maximal anticipation position and strength was defined by computer graphics animation. The results led to an equation for estimating anticipation. The maximal anticipation distance was directly proportional to the observer's view angle. The increase of this distance depended also on the increase of the stairs slope angle as well as the increase of their rise. The anticipation strength was directly proportional to the value of the stairs run and inversely proportional to the angle of the stairs slope.
