Stopping Sight Distance and Available Sight Distance: New Model and Reliability Analysis Comparison

open access: yesTransportation Research Record, 2017
Stopping sight distance (SSD) is an important design criterion used in the geometry of highways and streets. Design guidance implies that SSD is used to ensure safety along the roadway. This paper reviews SSD design criteria and develops an updated model to improve consistency between available sight distance and SSD criteria found

The Stopping Sight Distance Test for Freeway Based on the Operating Speed

open access: yesApplied Mechanics and Materials, 2011
In this paper, the stopping sight distance of passenger car based on the operating speed was regarded as guideposts, and its corresponding radius of horizontal curve and vertical curve was got according to the calculated results, and available for reference and application in the alignment design and safety evaluation for freeway.

Available sight distance on existing highways: Meeting stopping sight distance requirements of an aging population

Accident Analysis and Prevention, 2018
An important element of highway design is ensuring that the available sight distance (ASD) on a highway meets driver needs. For instance, if the ASD at any point on a highway is less than the distance required to come to a complete stop after seeing a hazard (i.e.
