Analyzing the distance visible to a driver on a highway is important for traffic safety,
especially in manoeuvres such as emergency stops, when passing another vehicle, or when …

The traditional two-stage highway design process provides separate processing of
horizontal and vertical alignments. One drawback of the two-stage methodology, however, is …

通过对多条高速公路的小客车视距进行检查, 发现中分带视距存在很多问题,
为了解决在具有中分带的道路上, 尤其是靠近中央分隔带护栏的左转曲线路段的停车视距不足的 …

Introduction The study focuses on sight distance restrictions on horizontal curves in highway
design. Barriers along open highways and walls on tunnels may restrict the available sight …

In this paper, a geometric model for predicting locations and times where sun glare has the
potential to affect drivers on roadways was developed. Existing or prospective highway …

提出了利用三维动态视距表征公路有效视距的思路和方法. 该方法以平纵线形数据为数据源,
利用三次B 样条曲线拟合公路线形. 综合考虑平纵线形组合, 驾驶员动态视野和车前灯照射范围 …

In current road design practice still a 2D approach is in use both with respect to the road
configuration and the vehicle's motion, despite the fact that a 3D approach regarding these …

This paper investigates potential Stopping Sight Distance (SSD) violation on divided
highways at left horizontal curves overlapped with crest vertical curves. The authors …

The paper introduces implementation of highways' stopping sight distance (SSD) and
decision sight distance (DSD) based on AASHTO modeling assumptions. SSD characterizes …

Abstract Introduction Stopping Sight Distance control of passing lanes of divided highways
represents currently a discussion point among researchers. A 3-D approach to address the …
