Recently, in Japan, improvements in infrastructures, such as guiding blocks, signal intersection, and pedestrian ITS, have been developed for visually disabled. In addition, the international standard and the domestic standard are improving. Thereby, the safety of visually disabled has been improved in pedestrian crossing. However problems continue. For example, that guiding systems do not have a clear evaluation method, and visually disabled accidents with pedestrians, bicycles and cars. In this paper, the crossing behavior of visually disabled and the effectiveness of guiding system are analyzed. One of the purposes is to obtain data of crossing behavior of visually disabled who are always passing through the specific crossing. The second, the effectiveness of guiding system continues to have analyzed by not subjectivity evaluation but by objective evaluation. Consequently, visually disabled who are always passing through the specific crossing were crossing safely. And the effectiveness of guiding system was shown to be effective.

Many of people with low vision walk using their low sight ability. They have difficulties to walk especially at night. In this research, we propose the guidance system with LED lighting, in order to make people with low vision easy to walk at night. First of all, the questionnaire was performed in order to clarify night walk of people with low vision. Many of them walk daytime using residual eyesight. They, however, can't use residual eyesight at night. Therefore they need guide and reduce going out at night. Secondly, we perform laboratory experiments by low vision subjects in order to verify effectiveness of the proposed system. As a result, the system is effective for those who walk under low illumination (6 lx or less). In addition we verify the suitable combinations of the installation interval and brightness of spots. "5 m interval and 90 lx brightness" and "7.5 m interval and 180 lx brightness" are efficient for the guidance of them.
