Tactile guiding lines (TGLs) developed in order to assist blind independent pedestrians in crossing intersections have come into widespread use in Japan. The TGLs are a kind of tactile marker placed on the asphalt pavement of a crosswalk. The aim of the study was to collect fundamental data concerning the specifications of TGLs. The findings of the research were as follows ;1)A field experiment was done to determine the optimum width of TGLs. Seventeen blindfolded sighted subjects were asked to walk along the TGLs with different widths, 30,40,50 and 60cm. Performance and impressions by the subjects suggested that the width of TGLs was necessary to be greater than 40cm.2)Longitudinal raised lines newly added to the TGL on pedestrian crossing were evaluated for their effects on detectability either by cane or foot. Eight blind persons participated in a field experiment. The results suggested that the longitudinal lines helped blind pedestrians to keep the direction of travel while they follow tactile guiding indicator on the pedestrian crosswalk.3)The effect of ambient sound conditions on the performance of blindfolded pedestrians to judge direction while walking in a straight line was tested. Experiments revealed that exposure to ambient sound had the effect of causing subjects to veer significantly from their paths in a direction that was opposite to the source of the sound. Veering from the path was directly proportional to intensity of the ambient sound.

为了帮助盲目的独立行人穿越交叉路口的触觉指南（TGL）在日本广泛使用。 TGL是在人行横道沥青路面上放置的一种触觉标记。该研究的目的是收集有关TGLS规范的基本数据。研究结果如下：1）进行了一个现场实验，以确定TGL的最佳宽度。要求17个蒙住眼睛的视力受试者沿着不同宽度，30,40,50和60厘米的TGL行走。受试者的性能和印象表明，对TGL的宽度大于40厘米。八个盲人参加了一次实验实验。结果表明，纵向线帮助盲人行人在行人人行横道上遵循触觉指示指示器时保持旅行方向。3）环境声音条件对蒙上双重行人行人在直线上行走时判断方向的效果。实验表明，暴露于环境声音的作用是导致受试者沿与声音源相反的方向显着从其路径转向。从路径转向与环境声音的强度成正比。
