The lighting level of street light pole depends on the type of road:
Generally：Expressways and arterial roads: there are 2-4 lanes in one direction, or 4-8 lanes in both directions. The main function of the road is to serve motor vehicle traffic. The speed is faster.
Secondary roads and residential roads:generally two-lane: motor vehicles, non-motor vehicles and pedestrian mixed traffic, the road conditions are more complicated, such as intersections, parking lots, etc.: slow speed.
Roads in industrial areas:generally two-lane; mixed traffic of motor vehicles, non-motor vehicles and pedestrians. During the rush hour, there is serious conflict between motor vehicle transportation and pedestrians. The road conditions are more complicated.The speed is slow, and the non-working hours lighting needs to consider the safety needs of pedestrians.
Roads in commercial shopping areas: generally 2-4 lanes, or pedestrian streets; mixed traffic of motor vehicles, non-motor vehicles and pedestrians, and serious traffic conflicts on holidays; slower speeds; lighting needs to be considered
Create a comfortable shopping environment.
Country roads:generally small roads with no lanes, or even unpaved roads, and the lighting is mainly used to identify directions.
In fact, no matter what kind of road, before lighting design, lighting engineers need to design base on the function of the road, traffic density, traffic complexity, traffic segmentation and traffic control equipment.
For example, the presence or absence of traffic lights, [High Pole Light Factory] divides the road into different lighting levels from M1 to M5.
