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.

Intersection sight distance analysis and guidelines
Transport Policy, 2009Guidelines for intersection sight distance are mostly outlined in general terms without showing effects of all the variables and assumptions involved. This paper provides theoretical analysis and sets guidelines based on the laws of motion for three types for intersection sight distances, namely (a) approach sight distance, (b) sign visibility sight ...

A framework for computing asset-sighting distance
Pattern Analysis and Applications, 2012Safety critical railway assets need to be visible from prescribed distances, ensuring safety. Traditional methods for measuring these sighting distances involve manual labour and disruption of rail services. Drawing parallels with other areas, efficiency and cost of such a task can be improved with automation.

Stopping Sight Distance and Available Sight Distance: New Model and Reliability Analysis Comparison
Transportation Research Record: Journal of the Transportation Research Board, 2017Stopping 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

Improvements to Sight Distance Algorithm
Journal of Transportation Engineering, 2001This paper describes improvements developed for an existing algorithm that calculates sight distance profiles based on horizontal geometry. Exact expressions are developed for vector derivatives for plane curves including clothoid spirals. Coordinate and derivative vectors are developed for partial spirals that possess nonzero curvature at both ends ...

Location and Distance Estimates by Blind and Sighted Children
Quarterly Journal of Experimental Psychology, 1975Blindfold normal, blindfold autistic and congenitally blind children made reproduction location and distance estimates of an arm movement. For each task they first experienced a standard vertical movement of a predetermined extent. In the test tasks which followed, they either reproduced the movement exactly, reproduced the end point although ...

Limited Sight Distance Effect on Speed
Transportation Engineering Journal of ASCE, 1979Sight distance is a basic element of geometric design having a direct bearing on the quality and cost of the designed road. An evaluation is made of speed characteristics as influenced by sight distance at six test sites, each a two-lane rural road. Measures were developed to express the average of driver responses along sections with limited sight ...
