城市道路平交口指路标志设置位置研究

Research on design for direction signs at intersections of urban roads

在指路标志信息量与认知性关系及可视距离的研究基础上,按照驾驶员获取标志信息并实施驾驶操作的过程,建立了驾驶员有效利用交通标志传递信息的条件,然后通过实例分析,提出了基于运行车速的城市道路平交口指路标志设置推荐标准。

Based on the research on the relationship between information amount of the direction signs and the recognition and visual range,the paper according to the signs information got by the drivers and the process of implementing the driving operation,establishes the conditions for drivers to use the information delivered by the traffic signs,and points out the recommended standard of the direction signs location at the intersections of urban roads.
