中文摘要：

针对色觉异常人群在不良可视环境下对交通信号辨识困难的问题，基于目前医学上普遍认同的色盲可见光谱和色盲色彩软件，结合我国交通信号灯特点及色觉异常者的视觉特征，设计一种比较经济可行的解决方案。通过在常规信号灯设备上加装辅助信号灯，并利用软件模拟色觉异常者的视觉进行对比分析，选取对比高的颜色作为辅助灯的颜色。方案效果模拟验证结果显示，本设计方案的交通信号具有较好的可辨识度，能够提高交通安全，体现了以人为本的设计理念。

英文摘要：

= An economically feasible design of traffic lights was proposed to help the color-vision deficient drivers to identify the signals under poor visual environment. Based on the generally accepted color-blind visible spectrum and a color-blind simulation software （Color Schemer Studio）, the design took account of both the characteristics of the existing traffic lights and the visual impaired people, and a low cost way of physicall.y rebuilding was proposed. The design achieved by install some auxiliary lights with strong color in contrast to the traffic lights. The simulation results show that the identifiability of the design signals is clear enough, which would improve the traffic safety.
