北京市立交桥指路交通标志可用性研究

摘要

Based on the 195 valid questionnaires out of 200 questionnaires to drivers, the present study discusses and analyzes the usability of traffic signs on overpasses in Beijing. The research results demonstrate that the driving efficiency of drivers is dramatically linked to the legibility, conciseness, continuity and compatibility of traffic signs, in which conciseness and compatibility contribute more than the others to driving efficiency. Last, some suggestions based on the study are also addressed to the design and setting of traffic signs.%通过对200位驾驶员进行问卷调查，获得195份有效问卷，由此分析了北京市立交桥指路交通标志的可用性。研究结果表明驾驶员的驾驶效率与指路交通标志牌的易读性、简洁性、连续性及兼容性4个维度存在着显著的相关性，其中简洁性、兼容性对驾驶员的影响更多。最后给立交桥指路交通标志的设计、设置提出了相应的建议。
