What is the importance of urban road lighting? The traffic network of the city is like the blood vessels of the city, especially at night, lighting is the key to the smooth flow of the city. Well-ordered road regulations not only affect the night traffic order, but also affect the nighttime living standards and quality of residents.
What are the main considerations for urban road lighting? In urban road lighting design, such as highway lighting design, the main characteristics of vehicles driving on the highway are fast speed and long distance. Driver safety and visual comfort should be considered in lighting design. For the relatively busy and congested main roads, it is necessary to ensure the safety and smooth passage of vehicles and people. In the design, sufficient illuminance and uniform light need to be considered, and reflected into the lamps, the light poles of the main roads are higher than those of the secondary roads. The lighting design considerations for branch roads, intersections, and interchanges are also different.
What are the types and characteristics of commonly used lamps for road lighting? One of the lighting fixtures commonly used on roads, road high pole lighting. The lighting arrangement, height, spacing, cantilever length, elevation angle, etc. of high pole lamps are all important factors affecting the lighting intensity. Secondly, the determinants of the installation height of the light pole mainly depend on the main width of the road surface, the way of lighting arrangement and the power of the light source.
In addition, economic factors such as energy consumption and maintenance conditions will also be considered in the installation of lamps. Generally speaking, the lower the installation height, the lower the total investment. However, high pole lights with low installation height are prone to glare. The higher the light pole, the larger the distance between them. Compared with the small distance, the small distance can improve the driver’s comfort.
Five steps for road design lighting.
Step 1: Identify the environmental conditions of the road. Such as the form of the road section, the width of the road surface and the isolation zone, the material and reflection coefficient of the road surface, the curvature radius of the curved road section, the layout of the road entrance and exit, level intersection and three-dimensional intersection, etc. In addition, there are greenery and buildings on both sides of the road, which are also conditions that need to be surveyed in the design.
Step 2: Determine the traffic flow and the flow of people. Designers need to understand the traffic flow and people flow of the road, as well as the traffic accidents on this road section and the public security situation nearby. The more comprehensive the research work on the road in the early stage of design, the more effective it will be in the later design.
Step 3: Determine the road grade and design standard according to the road conditions. According to expressway, main road, sub-arterial road, branch road and residential area road, it is divided into 5 levels, and the specifications are different according to different cities.
Step 4: Design the way of lighting arrangement. According to the different vehicle speeds during the driving process, the way of lighting is also different, and the designer needs to consider it comprehensively.
Step 5: After the above design is completed, it is to select the light source, select the lamp, debug and maintain, etc.
