Control of road lighting condition is a key factor in maintaining high standards of lighting and traffic safety for both drivers and pedestrians. Currently, street lighting measurements are taking place mainly at the reception of newly designed installations. It is also necessary to control the lighting status of already operating installations in order to maintain the assumed lighting parameters and carry out their possible maintenance. The article presents the method of measuring luminance using a point and matrix meter in the context of normative requirements.

This document addresses the development of a novel methodology to identify the actual maintenance factor of the luminaires of an outdoor lighting installation in order to assess their lighting performance. The method is based on the combined use of Radiance, a free and open-source tool, for the modeling and simulation of lighting scenes, and GenOpt, a generic optimization program, for the calibration of the model. The application of this methodology allows the quantification of the deterioration of the road lighting system and the identification of luminaires that show irregularities in their operation. Values lower than 9% for the error confirm that this research can contribute to the management of street lighting by assessing real road conditions.

AbstractHere the first photometric study of road-lighting white light-emitting diodes (WLEDs) integrated with semiconductor colloidal quantum dots (QDs) is reported enabling higher luminance than conventional light sources, specifically in mesopic vision regimes essential to street lighting. Investigating over 100 million designs uncovers that quality road-lighting QD-WLEDs, with a color quality scale and color rendering index ≥85, enables 13–35% higher mesopic luminance than the sources commonly used in street lighting. Furthermore, these QD-WLEDs were shown to be electrically more efficient than conventional sources with power conversion efficiencies ≥16–29%. Considering this fact, an experimental proof-of-concept QD-WLED was demonstrated, which is the first account of QD based color conversion custom designed for street lighting applications. The obtained white LED achieved the targeted mesopic luminance levels in accordance with the road lighting standards of the USA and the UK. These results indicate that road-lighting QD-WLEDs are strongly promising for energy-saving quality road lighting.

The article reveals the question of achieving security for people on the streets at night with the help of artificial lighting. The author analyzed the factors affecting traffic safety and the possibility of creating the necessary visual conditions for this by means of street lighting. In addition, the article raised an important question regarding the characteristics of the roadway. It is noted that the modern pavement is not standardized on the lighting characteristics. Knowing the spectral characteristics of the applied light sources, these data could be applied in the development of new types of canvases that would allow achieving a new level of illumination in terms of both improving the quality and its efficiency and economy. Without this, it is impossible to talk about the maximum efficiency of the use of the luminous flux as a whole. For existing lighting systems, the brightness calculation is performed by measuring the illumination and reflectivity of the road surface. The obtained brightness values are entered into the mesopic photometric system in order to determine the parameters of the complete system, which provides equivalent visual perception of the illuminated objects and is intended to replace the existing installation. To determine the required lamp power when replacing existing luminaires, it is recommended to use a mesopic photometric system, which allows you to perform calculations taking into account the S/P ratios. In this regard, it is necessary to thoroughly review the computer programs used in the creation of the lighting project, as well as to ensure active participation in international cooperation in the formation of modern lighting standards.

The determination of the route of movement is a key factor which enables navigation. In this article, the authors present the methodology of using different resolution terrain passability maps to generate graphs, which allow for the determination of the optimal route between two points. The routes are generated with the use of two commonly used pathfinding algorithms: Dijkstra’s and A-star. The proposed methodology allows for the determination of routes in various variants—a more secure route that avoids all terrain obstacles with a wide curve, or a shorter route, which is, however, more difficult to pass. In order to achieve that, two functions that modify the value of the index of passability (IOP), which is assigned to the primary fields that the passability map consists of, have been used. These functions have a β parameter that augments or reduces the impact of the applied function on IOP values. The paper also shows the possibilities of implementation of the methodology for the movement of single vehicles or unmanned ground vehicles (UGVs) by using detailed maps as well as for determining routes for large military operational units moving in a 1 km wide corridor. The obtained results show that the change in β value causes the change of a course of the route as expected and that Dijkstra’s algorithm is more stable and slightly faster than A-star. The area of application of the presented methodology is very wide because, except for planning the movement of unmanned ground vehicles or military units of different sizes, it can be used in crisis management, where the possibility of reaching the area outside the road network can be of key importance for the success of the salvage operation.

The Impact

The increase in population, urban development and road construction are the demands of many communities in obtaining public street lighting for road users by providing better services. Public street lighting has become a necessity for many people, which is very important for two-wheeled, four-wheeled, and many-wheeled drivers for safety and comfort in traffic, especially at night. Therefore, the authors conducted a new research design by arranging public street lighting in the area of ​​the Depok Cilodong highway, with the aim of providing the beauty of the road environment by the model of the arrangement and installation of poles, pole height and PJU lamp models to the road body. Its uniqueness is seen from the perspective of the side of social and environmental impacts that are generally not seen by the local government and the level of evenness of road lighting on road materials is still lacking, so that the impact on the road user community is better and more modern. The method used with the Dialux EVO 8.2 Program for short road lengths can choose street lights taken from the IES Lighting data on the 10W Eco Led, 10 VAC Milky Way, which is installed with a height of 8 meters with a distance between poles 15 meters with a large amount of procurement allows for high costs. For the long distance of the road, you can use the 20W Led Bimasakti Eco street light, 10 VAC, which is installed with a height of 8 meters and 20 meters between the poles. So by analyzing the selection criteria, it is capable of producing street lighting with lighting levels in accordance with SNI 7391-2008 and considering the quantity of material procurement as well as the tipping point which has an impact on financing for installation services.

Target Visibility

Street lighting ensures visibility and legibility for road users. In this paper, performances of the lighting installation of four road sections with different type of road surface are simulated in accordance with guidelines and road lighting standards. Then, the calculation of the visibility level of a target according to the Adrian’s model is included. Next, the light reflections on the road surface are added to the calculation of the target luminance. For this, the area considered in front of the target as well as the number of elementary surfaces are fixed and a Q_0-scaling of the r-table obtained for α=45° is performed. We compare the results obtained for each section with and without considering the light reflections and conclude that there is negligible incidence of the nature of the road surface on the target luminance. However, an effect of the road surface on the visibility level of the target is observed.

The Jakarta Outer Ring Road North W2 Section I has a different road width and also an interchange that is curved like a circle. On this toll road the distance between the piles used in both type of road is the same, that is equal to 30 m. Determination of the distance between the poles of the street lighting for straight roads and curved paths in this thesis using the phytagoras method. Where the distance between the lampposts for a straight road with the width of the road ranges from 4.5 m to 14.5 m from the calculation results require the distance between piles of 21.09 to 29.85 (<30 m) this results in less lighting standard. And for the width of the road ranging from 15.5 m to 30.5 m from the calculation results require the distance between the piles of 31.01 m to 50.82 m (> 30 m) which results in waste in the installation of the number of poles. Whereas for curved roads with a road width of 7.5 m for the placement of light poles in the arches of the road requires a smaller distance between piles of 20.96 m (<30 m).

Indian Scenario

The requirement of good lighting in road is an essential criterion. But the global energy crunch forces the optimization of energy consumption in road lighting design. The optimization of road lighting design starts with the determination of exact lighting class of the concerned road. The lighting class of different road depends upon few parameters related to traffic, road and its ambient condition. Most of the Indian roads are mixed and highly motorized in nature. In this paper, a new methodology for lighting classification of motorized Indian roads has been proposed. This proposed model has been developed based upon statistical analysis of traffic related parameters in Indian context. This model has also been validated in some real road context. Furthermore, this paper also demonstrates an approach for designing the lighting installation of a motorized road by maintaining the recommended lighting condition corresponds to the lighting class. This finally leads to an energy efficient design.
