小街区密路网交通标志缩尺研究

应用驾驶模拟器、眼动仪和调查问卷对小街区密路网条件下的交通标志设计方案和缩尺方案进行了分析探讨。驾驶模拟器采集的速度和加速度数据显示设计方案和缩尺方案具有差异显著性，眼动仪数据显示缩尺方案需要更多的注意力。调查问卷显示，大多数人主观上无法准确感受到两个方案之间的差异，缩尺方案的可行性还需要进行深入研究。

Study on Reduced Scale of Traffic Signs for Dense Road Network in Small Blocks

The driving simulator, eye tracker and questionnaire are adopted to analyze and discuss the design scheme and reduced scale scheme of traffic signs under the condition of dense road network in small blocks. The speed and acceleration data collected by the driving simulator show that there is a significant difference between the design scheme and the reduced scale scheme. The eye tracker data display scale scheme needs more attention. The questionnaire shows that the most people cannot accurately feel the difference between the two schemes subjectively. The feasibility of the reduced scale scheme needs to be further studied.
