Classification of Road Lighting

1. According to the function of road use, urban road lighting can be divided into two categories: motor vehicle traffic road lighting mainly used for motor vehicles and pedestrian road lighting mainly used for non motor vehicles and pedestrians.

2. The lighting of motor vehicle traffic roads should be divided into three levels based on expressways and main roads, secondary roads, and branch roads.

evaluating indicator

1. The road lighting for motor vehicle traffic should be evaluated based on the average brightness (or average illuminance) of the road surface, the uniformity of road surface brightness and longitudinal uniformity (or uniformity of road surface illuminance), glare limitation, environmental ratio, and inducibility.

2. Pedestrian road lighting should be evaluated based on the average illuminance, minimum illuminance, and vertical illuminance of the road surface.

Standard values for road lighting for motor vehicle traffic

1. The lighting standard values for motor vehicle traffic roads with continuous lighting should comply with relevant regulations.

2. When designing road lighting, it should be ensured that it has good inducibility.

3. When selecting lighting standard values for roads of the same level, consideration should be given to the nature and scale of the city.
