项目摘要

Tactile guiding lines (TGLs) developed to assist visually impaired 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. In an experimental study, we evaluated the tactile sign that is installed at the entrance to each crosswalk, designed to help users find the position and direction of each TGL. The results showed that the presence of the tactile sign improved the subjects' performance of crossing. However, all subjects had difficulties in finding the tactile sign at the entrance to the crosswalk because of its small size. As a means to reduce the difficulty, we planned to use the sound of an audible traffic signal (ATS). The ATS speaker is usually attached to a pole that holds the pedestrian signal and is located at either side of an entrance to the crosswalk. In the test intersection, we repositioned the speaker to above the tactile sign to help users find the sign more easily. Two field experiments were performed to evaluate the effects of speaker position on subjects' performance of finding the tactile sign. The results showed that the speaker placed above the tactile sign contributed to better user performance. The position of ATS speaker should be very important to development of the TGL installation guidelines.

触觉引导线（TGL）的开发，以帮助视障独立行人过十字路口，已在日本得到广泛使用。TGL是一种放置在人行横道沥青路面上的触觉标记。在一项实验研究中，我们评估了安装在每个人行横道入口处的触觉标志，旨在帮助用户找到每个TGL的位置和方向。结果表明，触觉标志的存在提高了被试的穿越成绩。然而，所有的受试者都很难找到的触觉标志在入口处的人行横道，因为它的小尺寸。为了减少困难，我们计划使用音响交通信号（ATS）的声音。ATS扬声器通常连接到一个杆，持有行人信号，并位于任何一侧的入口到人行横道。在测试交叉路口，我们将扬声器重新定位到触觉标志上方，以帮助用户更容易找到标志。通过两个现场实验，研究了说话人的位置对被试发现触觉信号的影响。结果表明，扬声器放置在触觉标志上方有助于更好的用户性能。ATS扬声器的位置对TGL安装指南的制定非常重要。
