Setting principle

1. The setting of road traffic signs should aim at road users who are not familiar with the surrounding road network system, comprehensively consider the surrounding road network and road conditions, traffic conditions, meteorological and environmental conditions and other factors, and formulate reasonable setting standards according to the functions of various traffic signs and the behavioral characteristics of drivers.

2 secondary and above highways and other grades of national highways and provincial highways should give priority to setting up guiding signs. Other expressways or expressways without relevant guiding signs may be provided with necessary warning signs after demonstration. Prohibition signs should be set in a conspicuous position near the effective place of traffic laws and regulations, and should avoid interacting with other traffic signs.

Speed limit signs should be set according to the traffic capacity of different sections, the proportion of vehicles and the speed of vehicles.

3. When selecting the destination information marked by road signs in the road network, we should consider the road network density, road grade, road function and destination popularity in a unified way. Different kinds of traffic sign information should echo each other, and there should be no information interruption.

4. The positions of longitudinal and transverse traffic signs on highways shall conform to the provisions of the current Road Traffic Signs and Marking (GB5768). Traffic signs located in the roadside safety net areas of expressways and first-class highways shall be protected by dismantling energy dissipation structures or setting guardrails in accordance with the structural specifications of the signs, and traffic signs located in other roadside safety net areas shall be induced when necessary.

5. Any part of road traffic signs shall not intrude into the road building clearance. The installation height of roadside post traffic signs should consider the board specifications, the linear and topographical features of its position, and whether there is pedestrian traffic. The clearance height of suspension signs such as cantilever and gantry should be 20-50cm greater than the road clearance.

6. When installing traffic signs, the normal of the sign board should be parallel to or at a certain angle with the highway centerline. The forbidden signs and indicating signs installed on the roadside are 0-45, and the guiding signs and warning signs are 0- 10. When installing cantilever, portal or attached hanging signs, the installation angle of the signs should be perpendicular to the road centerline or 0- 10.
