铁路色灯信号新编码系统的心理学研究

A Psychological Study on the New Coding System for Railway Light Signals

本研究在实验室和野外条件下模拟晴朗的白天司机距离信号机1000米观察信号的情境,对铁路色灯信号新编码系统的可行性进行了人机匹配实验.实验Ⅰ和Ⅱ采用了传统的信号反应时和正确率测量方法,实验Ⅲ则模拟长时警戒状态下对信号的译码.被试包括有行车经验的机车司机和非司机男女青年.通过各种实验条件的综合,对该编码系统做了较有实用价值的评价.

Three experiments were carried out to examine the avaliability of the new coding sys-tem for railway light signals in both laboratory setting and field.In experiment Ⅰ,the reac-tion times to the colored light signals and the percent correct identification were measured.In experimant Ⅱ,the encoding performance was studied in a simulated long-term vigilancetask.The subjects were selected from engine drivers and other adults.The results supplied apsycho-physical analysis of the new coding system.
