| 摘 要： | 视距审计是道路安全审计的重要内容。讨论了几个比较关键、但又容易被忽视的视距问题,包括平曲线路段中央分隔带护栏、桥墩和绿化对邻近车道的视距遮挡问题,凸、凹竖曲线的夜间视距问题以及因运营不畅造成的车辆排队视距问题等。力求通过安全审计,提高我国高速公路安全设计水平。

| Abstract: | Sight distance is a critical review element in road safety audit.Some critical but easily neglected freeway sight distance issues were discussed.These include: the narrow-median induced sight distance insufficiency for adjacent fast lanes at horizontal curves;night time sight distance issues for vertical curves;and back of queue sight distance issues caused by operation difficulties at service area.These discussions can help improve freeway design through the road safety audit process. |
