摘要:

为缓解高速公路隧道照明能耗高、交通事故损失大且难以救援等问题。借鉴建筑照明领域的线性照明技术理念,提出高速公路隧道线性诱导系统设计方法;综合考虑空间路权、驾驶人因及驾驶任务等指标,构建基于事故预防的线性诱导系统评价体系;分析线性诱导设计的适用性,提出高速公路隧道交通安全整体优化思路,并以隧道入口为例,验证线性诱导系统的作用效果。研究结果表明:利用逆反射、蓄能自发光以及发光二极管(LED)发光显示技术,基于线性诱导原理重构高速公路隧道视觉参照系,能够低成本实现隧道空间的多层线形诱导和多层轮廓诱导,满足不同视觉条件下驾驶人对交通信息的视认能力,确保视线诱导的连续性、一致性,引导驾驶人采取安全合理的行为决策,分解驾驶任务,并减少驾驶行为操作失误的可能性,实现高速公路隧道照明节能与交通安全的统一。

Abstract:

In order to alleviate problems of high energy consumption, significant traffic accident losses and difficulties in rescue associated with expressway tunnel lighting, referring to linear lighting technology in the field of architectural lighting, a design method of linear guidance system for highway tunnel was proposed. Considering spatial rights-of-way, driver factorsand driving tasks, an evaluation framework of linear guidance system based on accident prevention was established. Applicability of linear guidance design was analyzed, and an overall optimization approach for expressway tunnel traffic safety was presented. The effectiveness of linear guidance system was validated using tunnel entrance as an example. The results show that by utilizing retroreflection, self-luminous energy storage and Light Emitting Diode(LED) display technologies, visual reference system in expressway tunnels can be reconstructed based on principles of linear guidance. Based on this, multi-layer linear and contour guidance in tunnel space can be realized at low cost, which meets drivers' ability to perceive traffic information under different visual conditions It ensures continuity and consistency of visual guidance, guides drivers to make safe and rational behavioural decisions, decomposes driving tasks, and reduces possibility of driving operation errors. Thus, integration of energy-saving expressway tunnel lighting and traffic safety is achieved.
