| dc.description.abstract | The importance of adequate lighting in buses for urban passenger transport is great, for the reason that adequately designed lighting contributes to the comfort and safety of passengers. In addition to the fact that passengers expect that the buses participating in public transport meet adequate lighting conditions, they also expect that identical or approximately the same lighting conditions (as well as other environmental conditions) exist in all buses, regardless of brand or type of a bus that participates in transportation. In this way, a balanced quality of service is achieved and a positive effect on customer satisfaction. The focus of this paper is to investigate the existence of differences in the distribution of light in different types and brands of buses used for urban passenger transport in Belgrade. For this purpose, five locations where illumination was measured were selected: at eye level for the seated passenger position, at floor level at the aisle location, at floor level at the stair location, at eye level for the standing position of the passenger at the aisle location and at the location of warning signs. The research included 140 buses that have participated in urban passenger transport. As an additional factor, the zones of higher and lower street lighting were taken into account. This factor has not previously been taken into account in considerations of this kind. Based on the testing of statistical hypotheses, the results of the research showed that at none of the five mentioned locations there is a uniform level of illumination in the observed sample of buses. In order to eliminate this shortcoming, certain recommendations have been given for lighting designers of buses. | sr |
