摘要
根据城市跨江桥梁事故形态,充分利用现有桥梁交通附属设施,设计多频率、多色彩的视觉信息流改善方法.利用3ds Max仿真软件对城市桥梁进行模拟实验,利用E-prime软件进行了基于反应时法的车速感知心理物理实验,结果显示:用反应时法测量被试的感知速度,可以很好的进行高斯拟合;改善前被试白天速度低估8.72%±1.57%,夜晚速度低估11.89%±2.04%,改善后被试白天速度高估5.64%±3.27%,夜晚速度高估11.05%±1.21%.
According to the urban cross-river bridges' accident forms,using the bridge traffic affiliated facilities the paper design visual information flow of multi frequency and multi colors improvement of method.Using the reaction time method by 3dx Max simulation software and E-prime software,psychological experiment was carried on.The results showed that:the subject's perception speed can be fitted with Gaussian well by reaction time method;before improvement the speed underestimate of 8.72±1.57%in the daytime could be changed into the speed overestimate of 11.89±2.04% at night,and after improvement the speed overestimate of 5.64±3.27%in the daytime could be changed into the overestimate of 11.05±1.21% at night.
