碩士 === 大同大學 === 工業設計學系(所) === 107 === Since 2014, all kinds of zebra crossing designs have swept the world, and the main function of the zebra crossing has not changed much since its invention. The main purpose is to let the driver slow down in this section so that pedestrians can Safe crossing the road, the 3D zebra crossing drawn by the illusion method has been confirmed by the Russian and Taiwanese governments to slow down the driving. In order to gain a deeper understanding of the relationship between the 3D zebra crossing and driving deceleration, this study will explore the difference between the thickness of the 3D zebra crossing and the shadow configuration in the case of low-speed driving, so that the driver can "want to drive" and "want to brake the car" Relevance. Based on the existing floating and stereoscopic 3D zebra crossings, through the intersection of artificial intelligence, marking regulations and human eye discrimination, the wrong visual thickness of 45 cm, 50 cm and 60 cm is obtained, and the shadows caused by parallel light and point light source are mutually arranged. After that, 13 kinds of 3D stereo zebra crossings were drawn for experiment. First, use the countdown timer to measure how far the brake time is from the zebra crossing, and then use the Likert scale to get the stereoscopic feeling and the data of the degree of driving. Finally, the experimental results of 30 subjects were analyzed by single-factor variation, and the three-dimensional sense, the degree of driving, and the time of driving were significant. After comparing and discussing the data, this study found that (1) when there is no shadow, the wrong visual thickness is 60 cm and the stereoscopic effect is better than 50 cm and 45 cm. (2) The more obvious the shadow position is, the stronger the stereoscopic effect is. The time point of wanting to drive the car will be slightly earlier than other 3D zebra crossings. (3) The illusion zebra crossing of the floating category as a whole is higher in score than the steric imaginary zebra crossing under the same conditions. (4)Only floating type visual thickness 45 cm shadow under, floating type visual thickness 50 cm shadow under, floating type visual thickness 50 cm shadow in front, stereoscopic visual thickness 50 cm shadow in front, the above 4 kinds of zebra crossing, can be safe Remind the driver to drive before the brake distance (10.73 meters).
