| 摘要： | Over the last 30 years remarkable progress has been made in the mitigation of roadside safety problems. Unfortunately, roadside crashes remain a serious problem-more than 14,000 people are killed and almost 1 million injured in vehicle run-off-the-road collisions annually, at an estimated cost to society exceeding $80 billion per year. The Texas Department of Transportation (TxDOT) installs several different roadside safety devices to reduce the severity of run-off-the-road crashes. The devices currently in use include guardrails, concrete barriers, end treatments, crash cushions, and special sign support designs |
