摘要
高等级公路设计时,部分路段平曲线所需的横净距大于中央分隔带外侧超车车道的自然横净距,应采取加宽措施,使横净距满足停车视距要求,减少行车安全隐患。
Widening measures should be taken when the cross sections of horizontal curve spacing is greater than the central median Natural horizontal spacing of the outside overtaking lane during the design of highway.As a result,the horizontal spacing meets the requirements of the stopping sight distance and reduces the traffic safety hazard.
