This paper analyzed the perception of an angle between crossing roads. Experiments were performed where subjects were asked subjects to draw figures of intersections visualized on a computer display as computer-graphics. From the experiments, the following results were obtained: 1) perception of an angle is affected by its perspective angle shown on the display, 2) the difference between the true and perceived angles increases with that between the true and perspec-tive angles, 3) the variation of perceived angles among subjects increases with the difference between the true and perspective angles.
