Modelling of Three-Dimensional Intersection Sight Distance [PDF]
, 2021 Intersection sight distance(ISD) is an important design element. Each intersection has a potential for several different types of vehicular conflicts that can be greatly reduced through the provision of proper sight distance. Current guidelines do not adequately address sight distance requirements for intersections located on horizontal curves alone or

Location Variability Confidence Interval Model Using Statistical Inference for Over-rooftop Paths and Signal Data Classification Method [PDF]
Journal of Electromagnetic Engineering and ScienceIn this paper, statistical inference is used to predict a practical linear equation for determining signal loss rates over distance in a suburban over-rooftop path under both line-of-sight (LoS) and non-line-of-sight (NLoS) conditions.

Interchange Sight Distance and Design: Aspects and Implementation
Open Journal of Civil Engineering, 2021 The primary purpose of an interchange is to enable an appropriate level of access to the freeway in a safe and beneficial way to the driver. It improves road safety and traffic operation by reducing or eliminating traffic conflicts that would occur if grade separation were not provided (e.g. intersection).

Determination of Sight Distance on a Combined Crest and Circular Curve in a Three Dimensional Space
International Journal of Transportation Science and Technology, 2012 The sight distance (SD) on a two-dimensional (2-d) curve, namely, a vertical curve or a horizontal curve, has been well understood and documented for roadway geometric design in literature.

Incorporating Uncertainty into the Estimation of the Passing Sight Distance Requirements
Computer-Aided Civil and Infrastructure Engineering, 2007 Passing sight distance (PSD) is provided to ensure the safety of passing maneuvers on 2-lane, 2-way roads. Many random variables determine the minimum length required for a safe passing maneuver. Current PSD design practices replace these random variables by single-value means in the calculation process, disregarding their inherent variations, which ...

Deriving Sight Distance on a Compound Sag and Circular Curve in a Three Dimensional Space
International Journal of Transportation Science and Technology, 2012 Insufficient roadway sight distance (SD) may become a contribution factor to traffic collisions or other unsafe traffic maneuvers. The sight distance (SD) for a two-dimensional (2-d) sag or circular curve has been addressed in detail in various traffic ...
