1.0.1 This guideline was formulated to make the design of highway safety facilities be safe, reasonable, economical and practical with advanced technology and high quality.
1.0.2 This guideline is applicable to the constructed and renovated highways.
1.0.3 The contents of the design of highway safety facilities shall include barriers, traffic signs, traffic markings, fence, overpass fencing facilities, anti-glare facilities, delineator and movable barrier, and so on.
1.0.4 The overall design of highway safety facilities shall be carried out in combination with the conditions of road net and conditions, the traffic conditions and the environmental conditions. The installation principle and design scheme of the traffic safety facilities adopted for one same highway should be consistent. The traffic safety facilities shall be mutually coordinated and cooperated between them and with the main works and other facilities of highway.
