The Goal of Public Lighting Is Usually to Illuminate The Sidewalk Itself
The public lighting(CLASSIC) is not actually meant to show the road directly in front of the car, the car lights do this. But it does illuminate the adjacent area, alerting the driver to the dangers that may exist.
Pole height is very important in terms of light distribution, so transportation engineers often want to install the lights on higher speed roads.
Driving from a well-lit area to a dark area produces a similar effect. Therefore, ideally, if an area must be illuminated, the globe is mounted on a relatively high pole so that the light remains constant and the eye does not continuously readjust to achieve different brightness.
For pedestrians, the goal of public lighting is usually to illuminate the sidewalk itself. Additional black spots along the sidewalk can be created by a variety of conditions, including trees, large bushes, strange angles of the street, parking patterns, tall church spires or other buildings permitted by residential areas, or many other potential effects.
Keep in mind that as cycling becomes more popular, you need to monitor the presence of lighting on these new bike lanes.
