摘 要: 为了研究特殊情况下隧道内标志设置的理论及办法,通过分析隧道内有无紧急停车带的建筑净空限界,结合驾驶员的心理、生理特征,计算隧道内标志版面设置的合理几何尺寸;针对高速公路隧道路段运行环境特性,提出基于视觉连续性理念的隧道内标志设置,分别分析并计算在隧道内直线、平曲线及结合竖曲线的路段标志版面的设置位置,为隧道与互通式立交小净距的隧道内合理设置标志版面几何尺寸及位置提供理论指导。研究结果表明:隧道内标志设置的几何尺寸受到建筑净空的限制,其尺寸与通常情况下的尺寸不同,此外,通过视觉连续性的分析得出了标志在不同的隧道线形指标下设置的合适位置。

Abstract:In order to study the theory and method of setting traffic sign in tunnel under special circumstance, this paper determined the size of traffic signs in tunnel, by analyzing the clearance of the tunnel that with the emergency strip or not, combined with drivers psychological, physiological characteristics. Base on the special traveling environment characteristics of the tunnel and the concept of the visual continuity of the driver. The exact positions of the traffic signs that should be set in the tunnel`s horizontal curve and vertical curve were analyzed and calculated. Theoretical guidances to determine the traffic sign`s size and exact position in the tunnel which have limits net distance with the interchange were also provided in this paper. The study shows that: due to the limits of the tunnel clearance, it needs different size of the sign. And base on the visual continuity, right position for the sign is determined.

 

Key words: tunnel; horizontal alignment; vertical alignment; visual continuity; signs size; signs location
