Abstract

<p>The present study proposed a new road lighting using the pro-beam light distribution. Visibility performance provided by the current conventional road lighting brings some issues of concern in terms of changes of pedestrian visibility depended on positional relationship between location of pedestrian and luminaries. A field experiment was conducted on a test track using 12 participants. In this experiment, as simplified pro-beam road lighting was used to evaluate an effect of positive contrast consistently on visibility of pedestrian on the test track. We evaluated visibility performance of the pro-beam road lighting compared with the conventional road lighting. Visibility level assessed by the subjects were measured on the test track. Results of the experiment indicated that visibility level of the pedestrians under the pro-beam road lighting was larger and constant rather than that under the symmetric road lighting. The pro-beam road lighting proposed by the present study might have a potential to show more positive effects on the road.</p>
