3. Triangular pyramid posture rigidity guardrail does not possess the flexible function of activity, when needs open the activity opening, can only move the guardrail along highway transversely and move, and operation intensity of labour is very big, forms the rigidity roadblock that is perceived by the coming and going vehicle of high-speed driving easily to lead to some traffic accidents that should not take place.

4. The cone-shaped road sign is used as a temporary separation guardrail, is easy to be knocked down by vehicles coming and going and is manually moved, is used as a temporary separation in the center of a road, has extremely low safety reliability, and is most not beneficial to the safety of road traffic driving.
