摘　　要：为了解长大下坡对交通安全的影响,控制长大下坡路段交通安全事故发生,本文分析了道路下坡坡度对交通安全事故的影响程度;基于我国交通安全事故形势,建议了以道路坡度和路线长度为控制指标的长大下坡分级标准;分析统计了建设中的德上山区高速长大下坡数量,建议了德上高速长大下坡交通安全设施设置。The impact degree of road slope on traffic accidents is analyzed in this paper in order to know the impact of long and steep downgrade sections on traffic safety and decrease traffic accidents in these sections. The classification of long and steep downgrade sections with road slope and road length as control indexes is put forward based on the situation of traffic accidents in our country. The statistic analysis for the long and steep downgrade sections of De-shang mountainous highway in construction is conducted and the traffic safety facilities for these sections are given.
