The invention discloses a compact type road traffic safety fence, which belongs to the technical field of traffic protection equipment. The compact type road traffic safety fence comprises stand columns, elastic rotation components and rails, wherein each rail comprises a first rail body, a second rail body and a third rail body; the first rail body and the third rail body have the equal length; one end of the first rail body or one end of the third rail body is fixed on one stand column; the other end of the first rail body or the other end of the third rail body is rotatably combined with the elastic rotation component and is fixed with the second rail body. According to the compact type road traffic safety fence, the design thought of an existing safety fence is changed, the rails are shortened, one end of the first rail body or one end of the third rail body is fixed on one stand column, the other end of the first rail body or the other end of the third rail body is rotatably combined with the elastic rotation component and is fixed with the second rail body, and connection strength between the rails and the stand columns is high; even if a vehicle crashes the fence, the vehicle cannot cross the fence; meanwhile, an installation process is simplified, the installation of the rails can be finished only by one or two people, and the number of operation personnel is few; in addition, the road traffic safety fence can be more conveniently installed, the installation time of the traffic fence can be greatly shortened in an engineering construction process, and a guarantee isprovided for putting roads into use in time.
