Development of the Program Road Lighting and Road Surface Property Measuring Apparatus |
| Abstract |
Average illuminance and luminance can be calculated by graphical methods to a certain extent, but to calculate for a wide place, a suitable software is needed. Softwares suitable for this purpose have been already developed in foreign nations, but the appropriate softwares for domestic use have not been developed. Therefore a program is developed which is executable in Hangul Windows. The softwares LAPRoad, is developed to calculate luminance and illuminance distribution of road surface, as well as average luminance and illuminance, overall uniformity, longitudinal uniformity, threshold increment, veilling luminance, and glare. And an apparatus that measures road surface reflection properties is developed. Because the road surface reflection properties is very important in luminance calculation, then concrete road surface reflation properties were measured. |
