accident information providing method using an impact-preventing member coupled to guardrail

摘要

The present invention is formed with an inner space at an impact preventing member (200) coupled to a guardrail (100) to prevent impact as an inner space of the impact preventing member (200) absorbs the impact when a vehicle collides with the guardrail (100). An accident information providing method using an impact preventing member coupled to a guardrail of the present invention prevents impact generated on the guardrail through the impact preventing member in a vehicle accident and notifies a signal detected through an impact detecting sensor.
