First, The urban road grade is divided into expressway, trunk road, secondary trunk road and branch road. The red line width control of each level: fast road is not less than 40 meters, main road is 30~40 meters, secondary road is 20~24 meters, branch road is 14~ 18 meters. Generally, rural roads are within ten meters, and the normal is about six meters.
(1) Expressway, there is a central separation zone in the urban road, with more than four motor vehicle lanes, all or part of which adopts three-dimensional intersection and control access for the car to drive at a higher speed. Also known as the car lane. The design speed of the expressway is 60~80km/h.
(2) Main roads, connecting the trunk roads of different cities, with traffic functions as the mainstay. The design speed of the main road is 40~60km/h.
(3) Secondary trunk roads, which undertake the traffic distribution function between the trunk road and each district, and have the service function. The design speed of the secondary trunk road is 40KM/h.
(4) Branch Road The connection line between the secondary road and the district road is mainly based on service functions. The design speed of the branch road is 30km/h.
Second, The average illumination of the expressway is 20lx, the uniformity is 0.4, the average illumination of the main road is 15lx, the uniformity is 0.35, the average illumination of the secondary trunk is 8lx, the uniformity is 0.35, the average illumination of the branch is 5lx, and the uniformity is 0.3.
Third, the solar street light interval
The solar street lamp spacing is also the street lamp spacing, which is determined by various factors such as the lighting power of the solar street lamp, the height of the solar street lamp, and the width of the road. The solar street lamp spacing is typically 3.8-4 times the height of the pole.
Fourth, the height of solar street light
The pole height of solar street lamp is generally 6 meters, 8 meters, 10 meters, 12 meters, 15 meters, etc. The specific use of solar street lamp height depends on the width of the road surface. Generally, if the single side cloth is used, the height of solar street lamp is the same as the width of the road surface. Or the height of solar street light is less than 1 meter of the road width. We have many solar street light projects for your refference.
The relationship between the common solar LED street lamp power and the pole height is generally: 30~60W solar street lamp height is less than 6 meters, 60~100W solar street lamp height is below 8 meters, and 100~150W solar street lamp height is below 10 meters. 60-watt LED lamp head, about 6 meters, with an interval of 15-18 meters; 8 meters of light poles are spaced at 20-24 meters, and 12 meters of light poles are 32-36 meters apart.
Fifth, Four basic ways of arranging solar street lights:
(a) single-sided arrangement; (b) double-sided staggered arrangement; (c) bilaterally symmetric arrangement; (d) centrally symmetric arrangement;
