Original Abstract

This article is a summary of the specific research project, conducted at the Institute of Forensic Engineering, Brno University of Technology (IFE BUT) in order to verify properties of selected light reflective and fluorescent materials and their properties compared with those obtained with conventional textile materials. The article summarises the results of laboratory and exterior measurements of selected light properties on a series of samples, including reflective materials used in the clothing industry, on warning garments and on various promotional items and at the same time including the most used materials and colors for outerwear. Within the laboratory measurements, inter alia, measurements of the diffuse and specular components of the reflected light, which is important for the visibility of these elements, were carried out. Following this measurement practical night measurements in the exterior were performed which showed that the results do not always correspond to those obtained from the laboratory measurements. The measurements also revealed major problems in the quality of some reflective components available on the market. The aim of the research is to demonstrate a fundamental difference in the visibility of pedestrians in a casual dress under reduced visibility compared to clothing equipped with reflective materials and to find the correlation between the laboratory results and the actual subjective perception of these surfaces in real life. The result of the project, after its completion, should be recommendations for the selection and placement of reflective components for pedestrians moving under poor visibility on the road, both in terms of color and size, and in terms of location for the best visibility.
