Escopo e aplicabilidade

This standard specifies the general provisions and setting requirements for traffic signs in traffic accident management areas. It is applicable to the setting of traffic signs during the on-site disposal of road traffic fatal accidents or expressway traffic accidents. Other road traffic accident site disposals may refer to this standard. It covers temporary traffic signs including warning signs, prohibition signs, and auxiliary signs used to protect accident scenes and prevent secondary accidents.

Requisitos técnicos

This standard outlines the requirements for temporary traffic signs used in accident management areas, categorized into pre-warning areas and warning areas. The warning signs include the traffic accident management sign, alignment guide signs, and two-way traffic signs. Prohibition signs include speed limit and no-entry signs. The standard mandates specific color and material requirements. The traffic accident management sign must use a fluorescent fire red background with black text and borders. The chromaticity coordinates for this specific color are strictly defined in a normative annex. Additionally, the retroreflection coefficient of the fluorescent fire red reflective film must meet specific performance criteria. Dimensional requirements vary based on road types. For expressways and urban expressways, the minimum side length for equilateral triangular warning signs is 700mm, while other road types have a minimum of 600mm. The signs must be portable, utilizing a folding panel structure if necessary, and must be equipped with a sturdy bracket structure that meets wind resistance and stability requirements as per GB/T 28651. Signs must be set up facing oncoming traffic and removed immediately after the accident scene is cleared.

Métodos de ensaio

The standard references specific testing and evaluation methods for materials and setup. The chromaticity coordinates of the fluorescent fire red color are tested under standard illuminant D65 with specific geometric conditions as defined in GB/T 3978. The retroreflection performance of the reflective film is evaluated against the requirements for Class IV fluorescent yellow reflective film specified in GB/T 18833-2012. The structural stability and wind resistance of the sign brackets are assessed according to the procedures in GB/T 28651.
