| 摘要： | The purpose of guardrail and median cable barrier is to prevent vehicles which leave the roadway from encountering life-threatening hazards, such as striking roadside obstacles or vehicles traveling in the opposite direction. In Florida, guardrail standards have been in place since the 1960s, but new guidance from the Federal Highway Administration based on changing make-up of the U.S. fleet resulted in an in-service performance evaluation of existing guardrail installations. |
