Calculating TIN-Based 3D Sight Distance and Its Evaluation on Drivers Free-Flow Speed
Shock and Vibration, 2021 Sight distance during driving may be limited by side factors such as mountain slopes or trees and buildings in horizontal curves and by the dome of the arc in vertical curves, and the night vision also can be limited in the sag vertical curves by the ...

Sight distances at unsignalized intersections: a comparison of guidelines and requirements for human drivers and autonomous vehicles [PDF]
Archives of Transport, 2021 Many traffic accidents are caused by unforeseen and unexpected events in a site that was hidden from the driver's eyes. Road design parameters determining required visibility are based on relationships formulated decades ago.

The Sight Distance Issues with Retrofitted Single-Lane HOV Facilities
International Journal of Transportation Science and Technology, 2013 It is well-known that obstruction inside a highway horizontal curve will lead to impaired sight distance. Highway alignment design standards in terms of the minimum horizontal curve radius are specified to allow for adequate stopping sight distance at ...

Stopping-sight-distance simulation using a new probabilistic approach
, 2015 Geometric design guidelines provide deterministic analytical formulas to facilitate the calculation of the distance required to perform emergency stops on highways. Such expressions include several pre-fixed parameters that may produce an oversized or even an uneconomical outcome.
