摘要
隧道出入口过渡段的"明暗适应"过程是产生道路行车安全问题的一个重要因素。文中基于隧道入口照度对车辆行车速度的影响,建立隧道入口照明过渡技术指标对速度的关系模型,进而通过运行速度差的道路安全评价中介指标,建立了评价隧道入口段道路行车安全性的隧道入口照度安全评价标准,为提高隧道入口的安全性提供了技术保证。
The so called ＂bright-to-dark＂ adaptation for vehicle drivers passing through the transition section of tunnel entrance is an important factor of the road traffic safety. Based on the impact of brightness on tunnel entrance on vehicle speed, the relationship model was established between the technology index of brightness transition for tunnel entrance and vehicle speed in the paper. Further- more, the evaluation standards of tunnel entrance safety were established using tunnel entrance illumi- nation safety index through the intermediary index of speed difference used to evaluate road safety.
