A Comparison of Light Sources Technologies of Vehicles Headlights Illuminating a Model Road

Abstract

The paper presents courses of measured values of vertical and horizontal illuminance on a sample section of a road. The model road was created at LIBROS safe driving polygon in Ostrava within the Comparative Measurement of Night Traffic Area, which was organized as part of the research task VI2VS/571 of BV III/I-VS programme entitled “Analysis of Road Traffic Participants Visibility so that it is possible to increase their safety in dusk and night”. Measurements were made for two model situations of road lighting: vehicle low beam headlights and a combination of road lighting and low beam headlights. Vehicles of the same type with low beam headlights with halogen, xenon and LED sources were used for the measurements.
