Reliability of sight distance at stop-control intersections

Proceedings of the Institution of Civil Engineers - Transport, 2016
The American Association of State Highway and Transportation Officials presents guidelines for intersection sight distance (ISD) based on extreme values of the component design variables such as speed and time gap. The guidelines for a stopped vehicle at a stop-control intersection on a minor road assume that the component design variables are ...

Three-Dimensional Stop-Control Intersection Sight Distance

Transportation Research Record: Journal of the Transportation Research Board, 2006
Intersection sight distance is an important design element. A stopped vehicle on the minor road needs sufficient sight distance to depart (cross, turn left, or turn right) safely, even though an approaching vehicle on the major road comes into view. Current AASHTO policy assumes that both minor and major roads are straight and intersect at right angles.

Required Stopping Sight Distance on Crest Vertical Curves

Journal of Transportation Engineering, 2001
Required stopping sight distance (SSD), used to calculate the minimum rate of vertical curvature or the minimum length of a crest vertical curve (CVC), is usually calculated on the assumption that the grade of the braking section is zero (G = 0). This assumption is not the worst case and may lead to the selection of a CVC on which there is a segment ...

A review of stopping sight distance in road design guidelines

Proceedings of the Institution of Civil Engineers - Transport, 2013
A fundamental principle of international road geometric design guidelines and handbooks is that along a roadway, the available sight distance should be sufficient to enable a driver, travelling at a reasonable speed, to stop before reaching a stationary object on his path.

Driver Braking Performance in Stopping Sight Distance Situations

Transportation Research Record: Journal of the Transportation Research Board, 2000
Assumed driver braking performance in emergency situations is not consistent in the published literature. A 1955 study stated that in an emergency situation “it is suspected that drivers apply their brakes as hard as possible.” This idea differs from a 1984 report that states drivers will “modulate”their braking to maintain ...
