Abstract |
Under night-time driving conditions, both cones and rods in eyeâs retina simultaneously act to influence mesopic vision in two areas: central and peripheral visions. However, as people age, the amount of light received as well as the color temperature perceived by the human eyes also change. This research, through simulations and scaled down experiments with various headlight color temperatures and two levels of fixed brightness, deals with differences in ability to detect and identify obstacles by the subjects in their 20âs and 50âs.
According to the results obtained from the experiments on peripheral vision, subjects in their 20âs detected the obstacles more quickly at the combined color temperature of 3,000K+4,500K than at the single color temperature of 4,500K, and likewise at 3,000K+5,500K than at 5,500K; this tendency was significantly more noticeable for the subjects in their 50âs. As for the central vision, the results showed that there were no significant differences due to color temperature between the subjects in their 20âs and those in their 50âs. Moreover, the landolt ring experiment conducted under low luminance yielded higher percentage of correct answers at combined color temperatures. |

Abstract |
There are very few countries that have provisions addressing the energy efficiency of the whole street lighting system, such as Spain or the Netherlands. Nevertheless, there is not an agreement about how energy efficiency must be assessed. The Spanish Government contemplates it in the Royal Decree 1890/2008 with the goal of improving energy savings and efficiency. However, this has not obtained the expected results. Nowadays, energy efficiency of this kind of systems is assessed using a label. In the case of Spain, this label only assesses one magnitude. The contributions of this paper are two evaluation systems (kiviat diagram and pie chart) which assess five magnitudes: lamps, energy efficiency index, light pollution, renewable energy contribution, and harness of the luminous flux using dimming. After that, a survey was done to study several subjects: (1) if citizens are aware about the efficiency of street lighting systems, (2) whether the sample of colors used in the label is adequate, and (3) if our proposed systems could replace the current evaluation system. Finally, the paper finishes with the conclusions of the survey. |
