The research experiment was conducted to solve problems for the color-deficient drivers, who appeals difficulties in distinguishing the red signal from the yellow signal, typically on LED. It is internationally regulated that any signal color must be identified by the 100m distance. Many efforts have been done and many ideas have been tested for that purpose in the past, but no single idea has come to a sufficient conclusion. The hypothetical idea as a "universal-design" concept was invented and tested within the framework of this research ; a red signal light with "X" marked by the specific x-y valued color that the normal cannot see, but the color blinds can see at the distance of 100m. Information will be elegantly reached to those who are needed.The research investigated that either of the two methods to form a new red signal, which is to say that deigning the "X" by the difference of brightness, and designing that by the combination of colors and the difference of brightness, is effectively useful for the color deficient drivers. The second method was found to be much effective. However, although the existing LED technology permits these red signals with the special color-mounted "X," the market is not big enough at this time to produce the typical LED color. Thus, the economical feasibility should await the public consensus.The idea of this red signal has been recognized and enthusiastically supported by the Ministry of Police in Japan, who may implement in Japan, the Federal Highway Administration in the Ministry of Transportation, U.S.A., and Swedish Care Institute, Sweden. The research output is planned to be presented at the CIE conference in 2007. It is hoped that the concept developed by the auspices of the national research fund in Japan will be a global standard in the world of traffic signals. Needless to say, the signal will not only benefit the color blinds, but will contribute to the public safety as a whole.

该研究实验的目的是解决色觉缺陷驱动器的问题，他们认为区分红色信号和黄色信号（通常在 LED 上）很困难。国际上规定任何信号颜色必须在100m距离内识别。过去为此目的已经做出了许多努力并测试了许多想法，但没有任何一个想法得出足够的结论。在本研究的框架内发明并测试了作为“通用设计”概念的假设想法；带有“X”的红色信号灯，以特定的x-y值颜色标记，正常人看不到，但色盲在100m距离处可以看到。信息将被优雅地传递给需要的人。研究调查了两种形成新红色信号的方法中的任何一种，即通过亮度的差异来设计“X”，并通过组合来设计“X”。颜色和亮度的差异，对于颜色缺乏的司机来说非常有用。发现第二种方法非常有效。然而，尽管现有的 LED 技术允许这些红色信号带有特殊颜色的“X”，但目前市场还不够大，无法生产典型的 LED 颜色。因此，经济可行性有待公众共识。这一红色信号的想法得到了日本警察厅的认可和热情支持，并可能在日本实施，美国交通部联邦公路管理局和瑞典护理研究所，瑞典。研究成果计划在 2007 年的 CIE 会议上公布。希望在日本国家研究基金的支持下开发的概念将成为交通信号领域的全球标准。不用说，该信号不仅有利于色盲，而且将有助于整个公共安全。
