摘要
指路标志的信息量过多,使驾驶员在安全时间内识别有效信息难度增加。通过室内仿真实验和室外车载实验数据对比,研究标志信息量大小、驾驶员的驾驶经验和车速对驾驶员识别城市道路指路标志时间综合性影响。提出了城市道路指路标志信息量限值意见。
Too much information of guide signs will make it difficult for drivers to distinguish useful information in safe time.Laboratorial simulation data and practical vehicle records are compared in this paper to study the influence of information amount of guide signs,driver＇s experiences and vehicle＇s speed on drivers＇ distinguishing time.Based on the research,the limit value of information amount of urban guide signs is suggested in this paper.
