There are related regulations about the arrangement of street lights, and for different countries, they are different. Generally speaking, several ways to arrange the street lights include single-sided arrangements, bilateral staggered arrangements, bilateral symmetrical arrangements, etc. When arranged in different ways, the height and distance of the street lights will vary. For example, in some countries, when the cut-off street light is arranged on a single side, the height should be greater than the road width. And the distance should be less than three times their height.
