5.2. 1 Lighting I for general roads shall meet the following requirements:

1 The conventional lighting method shall be adopted, and the provisions in Article 5. 1.2 of this standard shall be met;

2. On roads with many trees and serious shading or narrow streets where it is difficult to install light poles in buildings, you can choose transverse suspension cable arrangement;

5.2.2 Lighting at intersections shall meet the following requirements:

1 The lighting level at the intersection shall comply with the provisions in Section 3.4 of this standard, and the average illumination within 5m outside the intersection shall not be less than1/2 of the average illumination at the intersection;

2 light sources with different color tables, lamps with different shapes, different installation heights or different lamp arrangements can be used at intersections;

According to the specific situation of the road, the lights at the intersection can be arranged unilaterally, staggered or symmetrically. Additional light poles and lamps can be installed at large intersections and glare can be limited. When there is a large traffic island, lights can be set on the island or high pole lights can be used for lighting;

4 Street lamps should be set at the end of the road at the T-junction (Figure 5.2.2-1);

The lighting of the roundabout should fully display the roundabout, traffic island and kerbs. When conventional lighting is used, lamps and lanterns should be located outside the circular road (Figure 5.2.2-2). The lighting of entrances and exits leading to each road shall meet the requirements of Section 3.4 of this standard. When the diameter of the roundabout is large, pole lamps can be installed on the roundabout, and the lamps and lanterns should be selected and the position of the pole should be determined according to the principle that the brightness of the roadway is higher than that of the roundabout.

5.2.3 The lighting of the curve section shall meet the following requirements:

1000 meters and above, the lighting of curved sections with a radius of 1 can be treated as straight sections;

2 For curved sections with a radius below 1000 m, lamps should be arranged along the outside of the curve, and the spacing between lamps should be reduced, preferably 50% ~ 70% of the spacing between lamps in straight sections (Figure 5.2.3- 1). The smaller the radius, the smaller the spacing. The length of the cantilever should also be shortened accordingly. On the reverse curve section, lamps should be fixed on one side, and when the line of sight is blocked, lamps can be added on the outside of the curve (Figure 5.2.3-2);

3 When the curved road section is wide and lamps need to be arranged on both sides, symmetrical arrangement should be adopted;

4 The lamps and lanterns at the corner shall not be installed on the extension line of lamps and lanterns in the straight section (Figure 5.2.3-3);

5 Lamps installed at sharp corners should provide sufficient lighting for vehicles, kerbs, guardrails and adjacent areas.

5.2.4 When lighting is installed on the ramp, the light distribution symmetry plane of lamps parallel to the road axis direction should be perpendicular to the road surface. In the range of convex vertical curve ramp, the installation spacing of lamps and lanterns should be reduced, and cut-off lamps should be used. 1 When conventional lighting is used, the brightness (or illuminance) generated by the lamps on the underpass road should be effectively connected with the brightness (or illuminance) generated by the lamps on both sides of the overpass road, and the average brightness (or illuminance) and uniformity in this area should meet the specified values. Lamps installed on underpass roads shall provide vertical illumination for the supporting structure of underpass roads;

2 Large-scale over-crossing roads and under-crossing roads can be illuminated by pole lamps, which shall meet the requirements of Article 5. 1.3 of this standard.

5.2.6 The lighting of interchange shall meet the following requirements:

4 Small interchanges can use conventional lighting. High-pole lighting should be used for large-scale interchanges, and it should meet the requirements of Article 5. 1.3 of this standard.

5.2.7 Lighting of urban bridges shall meet the following requirements:

1 The lighting of small and medium-sized bridges should be consistent with the lighting of the roads connected to them. When the width of the bridge deck is less than the width of the road connected with it, the bridge railings and kerbs should have sufficient vertical illumination, and lamps should be set at the entrance of the bridge;

The lighting of large bridges and small and medium-sized bridges with artistic and historical value should be specially designed to meet the functional requirements and coordinate with the style of the bridge;

3 glare should be limited in bridge beam lighting, and lamps with hoods or grilles should be used when necessary;

Bridges with multiple motor vehicle lanes should not install lamps directly on the railings.

5.2.8 Lighting of pedestrian underpass shall meet the following requirements:

1 Short straight pedestrian underpass with sufficient natural light can only provide night lighting:

2. Lighting devices should be installed at the entrances and exits of tunnels without street lamps nearby;

The average horizontal illumination in the tunnel should be 15lx at night and 50lx during the day. And proper vertical lighting should be provided.

5.2.9 The lighting of the footbridge shall meet the following requirements:

1 There is no need to set additional lighting for the footbridge with lighting facilities. The height, installation position and configuration of light source lamps and lanterns of conventional lighting adjacent to both sides of footbridges should be adjusted accordingly according to the needs of bridge deck lighting. When the illumination of the bridge deck is less than 2lx and the illumination of the steps is less than 5lx, the lighting of the footbridge should be specially set.

2. The average illuminance of footbridge deck with special lighting should not be less than 5lx, and the stepping illuminance should be appropriately increased, and the ratio of the horizontal illuminance of the stepping pedal to the vertical illuminance of the skirting board should not be less than 2:1;

Lighting facilities should prevent glare to pedestrians and motor vehicle drivers.

5.2. 10 The lighting at the intersection of road and railway shall meet the following requirements:

1 The lighting at the intersection should enable the driver to find the intersection, vehicles, pedestrians and other obstacles near the train and the intersection outside the parking sight;

The direction and level of lighting at intersections should help to identify traffic signs installed on vertical surfaces or road markings. The light color shall not be confused with the signal color;

3 Within 30m of the roads on both sides of the intersection track, the road surface brightness (or illuminance) and its uniformity should be higher than the road level, and the light distribution of lamps should not cause glare to drivers and pedestrians near the intersection.

5.2. 1 1 Road lighting near the airport shall meet the following requirements:

1 Road lighting near the airport should not be confused with the lighting signal system and site lighting on the airport runway;

When designing the road lighting in this area, we should abide by the relevant regulations of the aviation department and get in touch with it.

5.2. 12 Road lighting near railways and waterways shall meet the following requirements:

1 The light and color of road lighting shall not interfere with the light signals of railways and waterways and the vision of drivers and navigators;

2 when the road lighting is on the extension line of railway or waterway, it should get in touch with the railway or shipping department;

When the road meets the water surface such as lakes and rivers, and the lamps are arranged on one side, the lamp poles should be arranged on the water side.

5.2. Road lighting near13 Observatory shall meet the following requirements:

1 The brightness (or illuminance) on the road surface should be reduced by a standard;

2 The pavement should be paved with dark asphalt materials, and cement concrete pavement is not allowed;

3 Road lighting lamps with zero incident light flux ratio must be used.

5.2. 14 When roads (or sections) with lighting facilities and average brightness higher than 1.0cd/m are connected with roads (or sections) without lighting facilities, and the speed limit is higher than 50km/h, transitional lighting shall be set. The 1 tree planted on the newly-built road should not affect the road lighting;

2. The expansion and reconstruction of roads should consult with the garden management department to transplant trees that affect the lighting effect;

3 The following measures can be taken for the sections where the existing trees seriously affect the road lighting:

(1) Prune branches and leaves that block light;

(2) Change the installation mode of lamps and lanterns, adopt transverse suspension cable arrangement or extend the length of suspension cable;

(3) Reduce the distance between lamps or reduce the installation height. 1 The lighting level of sidewalk roads in residential areas shall meet the requirements of Article 3.5. 1 of this standard;

2 The installation height of lamps and lanterns should not be less than 3m. Naked lights should not be placed at eye level;

3. Lighting in residential areas and their vicinity should reasonably choose the position of light poles, light sources, lamps and lighting methods; The vertical illuminance generated on the bedroom window should not exceed the provisions of relevant standards. The average horizontal illumination of 1 should not be less than 1.5 times of the road where the crosswalk is located;

Two additional lights should be added to the crosswalk. Conventional road lighting lamps similar to motor vehicles can be installed near crosswalks, and directional narrow beam lamps can also be installed above crosswalks, but they should not cause glare to pedestrians and motor vehicle drivers. According to the need, a special light shield can be installed in the lamp or the inclination angle of the lamp installation can be controlled;

3 Different types of light sources can be used for road lighting. 5.3. 1 When setting decorative lighting on street trees, green belts, footbridges, bridges for moving vehicles and interchanges on both sides of motor vehicle traffic roads, decorative lighting should be designed by combining decorative lighting with functional lighting, which must meet the requirements of functional lighting.

5.3.2 The light sources, lamps and lighting modes of decorative lighting should be reasonably selected. The brightness of decorative lighting should be coordinated with the brightness of road surface and environment, and dynamic lighting with multiple light colors or multiple light patterns should not be used. The color, pattern, shadow and flicker of decorative lighting should be prevented from disturbing the vision of motor vehicle drivers.

5.3.3 The advertising lights set on the lampposts and on both sides of the road shall not obstruct the driver's sight and the identification of traffic signals.
