Abstract

This study presents a method for the evaluation of the visibility and physical reflection properties of marker posts in vehicle lighting. The solidity of the posts has also been studied. The physical measurement turned out to be very expensive. The method is suitable e.g. for the registration of the wear on a clean reflex from one period to another. The relative estimation (visibility) turned out to be easy and cheap to carry out, which makes this method suitable for a continuous follow-up to the visibility of marker posts. Furthermore, this method gives small random errors. Generally it can be said that the reflection properties of the marker posts have been dependent upon the weather conditions. The weather forecasts from the swedish meteorologist institute (smhi) have been too general to be of value. The tests will also continue during the winter of 1983 and 1984 and weather observations will be carried out by the staff exclusively. (Author/publisher).
