摘要
随着城市交通越来越拥堵和复杂化,不合理的指路标识成为了威胁交通安全的一大隐患.本文根据交通标志视认性的影响因素,结合安全人机学理论,运用变量控制理论,使用LabVIEW软件,设计并实现了指路标识视认性测试平台.该平台测试模块分别为极限信息量测试模块,标识字体测试模块,背景色和字体色对比测试模块,对比亮度测试模块和认读时间测试模块.本平台具有自动标识认读率计算和自动存储测试数据并输出的功能.依靠本平台获得的大量测试统计数据,可以为指路标识的合理化提供理论依据.
The development of modern urban transportation system has made the improper traffic signs a potential risk for the road traffic. According to factors to traffic sign comprehension, a traffic sign test bench was designed based on safety ergonomics theories and variable control theory using the LabVIEW programming code. This test bench has five test projects which are ultimate information content test, guide sign font test, sign background and sign font color comparison test,comparison contrast test and reading required time and reading correct rate test. This bench can calculate the reading correct rate and save and output the test results automatically. Relying on the huge amount of data obtained from this test bench,theory basis for a more reasonable guide sign system can be obtained.
