In this paper, we propose crossing designs and an evaluation method based on psychology, traffic engineering, graphic design, etc. from a global standpoint of road traffic flow, in order to prevent crossing, accidents caused by cars entering crossing immediately before train. We have made an information processing model that distinguishes conspicuity of detection / recognition from the concept of visibility, draw up a standardization plan considering a basic crossing design and setting according to crossing features, and develop an evaluation method based on the distance and response time.
