In order to eliminate glare on the surface of roadside signs, the signs should be rotated backwards by about 5 ° to avoid direct sunlight from the headlights. For general road sections, for roadside column signs, the distance between the inner edge of the sign board and the edge of the earth shoulder shall not be less than 250mm, the height of the lower edge of the sign board from the ground shall be 2m~2.5m, and the net height of the cantilever sign from the road surface shall not be less than 5m. 5.2.3 Sign support structure a.

The setting of traffic sign posts should consider the comprehensive situation of the road surface, plan reasonably, and important information can be repeated.

　　The gantry traffic sign pole is installed on the gantry, and the height of the lower edge of the sign above the ground should be greater than the clearance height specified for the road. 6. Attached traffic sign post: The sign is attached and installed on the overpass and nearby structures, and is divided into two types: attached on the roadway and attached on the road according to the position of the attached layout. 3、 Maintenance of road traffic sign posts. 1. The setting (adjustment) of road traffic signs should be completed before the completion and opening of new (renovated, expanded) roads, and the signs related to these new (renovated, expanded) roads in the road network should also be adjusted synchronously to improve their settings. When road traffic conditions change, the setting of relevant signs should be adjusted in a timely manner. Highway number and city road name signs should be used as much as possible to enable road users to understand their route and location. 3. The logo should be regularly cleaned and maintained to maintain sufficient reflectivity and ensure visual recognition. During the use of the logo, it should also be avoided from being obscured by numbers or being affected by street lighting that affects visual recognition. The shape and color of the logo should comply with the provisions of this section during its service life.
