ABSTRACT

Advertising media installed in the vicinity of the road may pose a potential threat to road safety. The driver’s perception of advertising depends on a number of factors, including the time of day, the location and dimensions of the medium, the luminance value, and the way the light is emitted. However, the excessive or incorrect distribution of media luminance in the driver’s field of vision, especially at night, may have a significant effect on the disturbance of the visual process. The driver’s night vision is generally adapted to low ambient luminance values, illuminated by vehicle and road lighting. Limiting the emission parameters of advertising by means of luminance values is one of the most common legal requirements in many countries, in the context of consent to the location of advertising on roads. For many years now, billboards with unknown emission characteristics and luminance values have been functioning in Poland. Exploitation of advertising media in the vicinity of roads requires the consent of the road manager to install the advertising media, which so far has not required confirmation of the maximum luminance values obtained. This led to the installation of aggressive advertisements on the roads, which disturbed the drivers. In order to determine whether there is a problem of excessive luminance of media in Poland and how high is the percentage of media, pilot studies were carried out on road sections selected by the research team. In the paper have been presented the results of measurements of light parameters (luminance of the carrier, luminance of the background and calculated contrast) and geometric dimensions of the advertising surface, using the original author’s procedure for 227 advertisements located in selected locations in Poland. The obtained measurement results showed that the permissible luminance levels were exceeded many times in the group of advertisements using LED sources. The authors have proposed to introduce a unified, operational procedure for measuring the luminance parameters of advertising media. The undertaken research is aimed at developing guidelines for road infrastructure managers concerning the reduction of brightness of advertisements located in the vicinity of roads.

摘要

安装在道路附近的广告媒体可能对道路安全构成潜在威胁。驾驶员对广告的感知取决于多种因素，包括一天中的时间、介质的位置和尺寸、亮度值以及光的发射方式。然而，驾驶员视野中媒体亮度的过度或不正确分布，尤​​其是在夜间，可能对视觉过程的干扰产生显着影响。驾驶员的夜视通常适应低环境亮度值，由车辆和道路照明照亮。在同意道路广告位置的情况下，通过亮度值限制广告的排放参数是许多国家/地区最常见的法律要求之一。多年来，具有未知发射特性和亮度值的广告牌已在波兰运行。在道路附近使用广告媒体需要得到道路管理者的同意才能安装广告媒体，目前尚未确认获得的最大亮度值。这导致在道路上安装了激进的广告，打扰了司机。为了确定波兰是否存在媒体亮度过高的问题，以及媒体的比例有多高，研究小组对选定的路段进行了试点研究。在论文中，介绍了光参数（载体亮度、背景亮度和计算对比度）和广告表面几何尺寸的测量结果，对位于波兰选定地点的 227 个广告使用原作者的程序。获得的测量结果表明，在使用 LED 光源的广告组中，允许的亮度水平多次超出。作者提议引入统一的操作程序来测量广告媒体的亮度参数。进行的研究旨在为道路基础设施管理者制定关于降低道路附近广告亮度的指导方针。作者提议引入统一的操作程序来测量广告媒体的亮度参数。进行的研究旨在为道路基础设施管理者制定关于降低道路附近广告亮度的指导方针。作者提议引入统一的操作程序来测量广告媒体的亮度参数。进行的研究旨在为道路基础设施管理者制定关于降低道路附近广告亮度的指导方针。
