The uniformity of lighting distribution on the roadway is essential factor for drivers and pedestrians's safety during nighttime in urban streets. Also, the importance of roadside trees is one of the growing concern for better citizens' health and mitigating environmental impact on the urban street. But roadway lightings and roadside trees have different design or planting standards and they are not integrated in the systemic viewpoint for better safety of users during nighttime. The purpose of this study is to propose a simulation approach which assesses lighting quality in the view of illumination uniformity distribution of roadway lighting from design step and consider the layout of roadside trees. For improving lighting quality of roadway, simulation approach is needed for assessing the impact of diverse planting situation of trees and encouraged from beginning of design step for roadway construction.

도로조명은 차량 운전자와 보행자에게 장애물을 신속 정확히 그리고 편안하게 볼 수 있는 도로의 야간 주위환경을 제공한다. 또한 밤에 도로설비 이용을 원활하게 함은 물론 교통의 흐름을 향상시켜 교통안전을 증진시키는데 목적을 두고 있다. 이 논문은 제주시내 중심가 8개 도로의 등기구 설치현황을 실측조사 하였으며 조명기구 배열방식을 고려하여 4개 도로의 조도 실측을 통하여 수평면조도와 균제도를 기준치와 비교분석하였다. 이를 토대로 제주시 주요 도심지 상가 도로에 관한 시뮬레이션으로 도로조명의 적합한 모델을 제시하였다.

The not an organization a branch stream the maintenance factor class on a class and the roadway type for roadway lighting design, the facted an insufficiency maintenance factor to apply our the country conditions. The consideration of maintenance factors is not being fully applied for roadway lighting design in Korea. This paper consider optical characteristics and maintenance factors as well as LID of Luminaires in designing roadway lighting. Consideration of maintenance factors that are neme specified according to LDD(Luminaire Dirt Depreciation), LLD(Lamp Lumen Depreciation), AADT(Average Annual Daily Traffic) based on IESNA regulation. The analyzed optical characteristics are applied for stagger and cross roadway types with maintenance factors in the range of 0.51$\sim$1.00 and equipment factor of 0.9.

Fixed lighting of public ways for both vehicles and pedestrians can create a nighttime environment in which people see comfortably and can quickly and accurately identify objects on the roadway being travelled roadway lighting can improve traffic safety, achieve efficient traffic movement and promote the general use of the facility during darkness. The design of a roadway lighting system involves consideration of visibility, economics, esthetics, safety and environmental conditions. This paper describe estimation of horizontal illuminance by actual measurement at main streets in Jejusi. We try to evaluate Jejusi Roadway Lighting Conditions for modeling by computer simulation.

본 논문에서는 2분할 수광 방식의 측정시스템을 이용하여 수도권 일대의 도로의 조도와 휘도분포를 측정하여 국내 도로조명 실태를 파악함으로써 조명시설들의 특징에 대하여 분석했다. 측정결과 대다수의 도로가 도로의 형태, 조명기구의 점등방식, 도로주변의 가로수 혹은 장애물 등의 영향으로 도로조명 허용기준을 만족시키지 못하고 있었다.

Roadway lighting is an integral element of a highway system. Luminaires on roadways provide viewing conditions for drivers and pedestrians during nighttime in order to improve safety. It is time-consuming and labor-intensive to manually measure roadway illuminance at predetermined spots with a handheld illuminance meter. To improve the efficiency of illuminance measurement, a remote-control electrical cart and a drone were utilized to carry an illuminance meter for the measurements. The measurements were performed on the marked grid points along the pavement. To measure the illuminance manually, one person measures illuminance at each grid point with the handheld meter and another person records the illuminance value. To measure the illuminance with the remote-control cart, the illuminance meter is attached to the cart and it measures illuminance values continuously as the cart moves along the grid lines. With the drone, the meter records the illuminance continuously as the drone carries the meter and flies along the grid line. Because the drone can fly at different heights, the measurements can be done at different altitudes. The illuminance measurements using the cart and the drone are described in detail and compared with manual measurements in this paper. It is shown through this study that automated measurements can greatly improve the efficiency of roadway illuminance data measurements.

In this paper it is examined the validity of luminance-to-illuminance conversion factor in the roadway lighting design. Luminance and illuminance distribution patterns were measured to yield the calculated conversion factor on the newly-constructed highway, and this value was compared to the conversion factor commonly used. We found that some discrepancy might exist between them due to difference in the values between the luminance yield factor and the coefficient of utilization. Therefore this fact must be fully understood in the roadway lighting design process.

The problems of light pollution first became an issue in the 1970s when astronomers identified the degradation of the night sky due to the increase in lighting associated with development and growth. As more impacts to the environment by lighting have been identified, many attempts have been made for reducing light pollutions. To prevent light pollution and increase energy efficiency, Seoul Metropolitan Government(SMG) replaced metal halide road lighting to LED luminaire in four arterial highway in Seoul. The present study compared the lighting characteristics of metal halide and LED luminaire in terms of Korea Standard for road lighting(KS A 3701) and BUG rating from Illuminating Engineering Society of North America(IESNA). The results showed that LED luminaire increased road surface luminance up to 2 times in average compared to the metal halide environment. Also, LED luminaire reduced the glare value by 2 times and luminous flux over 50% than the metal halide luminaire. In comparison with the BUG ratings, LED luminaire rated 1 degree lower for the backlight ratings and 3-4 degrees lower for the uplight ratings. The measured values testified that the LED luminaire is effective for roadway lighting and light pollution reduction.

환경오염과 에너지 절약차원에서 세계적으로 빛도 공해의 하나로 인식하고 각 나라에 맞는 법규와 규제 방식을 정하여 옥외조명을 관리하고 있다. 반면 국내에서는 광해 대책 안이 미비한 실정이다. 따라서 본 논문에서는 국내실정에 적합한 규제안과 광해 계산법을 마련하기 위해서 국제 조명단체들이 제시하는 광해계산법을 조사 분석하였다. 또한 여러 도로조명기구들을 선정한 후 광해계산법과 시뮬레이션 프로그램을 적용하여 광해요소들을 비교 분석하였고, 결론으로 우리나라에 맞는 광해 규제안을 제시하였다.

도로조명의 적절한 보수를 위하여, 조명 수준을 정확하게 파악하는 것이 매우 중요하다. 본 논문에서는 2분할 수광방식을 고안하여, 차량을 이용한 조도측정시스템을 개발하였다. 이 시스템은 넓지 않은 면적을 차지하고 도로의 흐름을 차단하지 않고 신속하고 신뢰성 높은 데이터를 자동으로 측정 저장할 수 있다. 따라서 도로조명 측정에서 많은 비용과 시간을 절약할 수 있다.
