Analysis of passing sight distance using first-order reliability method [PDF]
, 2021 Current passing sight distance requirements for two lane highways by the American Association of State Highway and Transportation Officials are based on field studies conducted between 1938 and 1941 which use deterministic values for its design variables such as passing sight distance, speed of the passing vehicle, speed differential between the passed

Sight Distance Standards Based on Observational Data Risk Evaluation of Passing [PDF]
Transportation Research Record, 2014 The paper presents an application of a reliability analysis for evaluating the risk associated with passing sight distance (PSD) standards in terms of the expected probability of noncompliance. Calculation of PSD is required to determine where drivers can safely execute passing maneuvers.

Rural Roads’ Passing Sight Distance Control Along Crest Vertical Curves [PDF]
InfrastructuresPassing sight distance (PSD) is a vital design element that directly imposes economic, as well as safety and operational, considerations. The provision of PSD is highly prioritized, at least for rural road sections without additional passing lanes.

Incorporating Uncertainty into the Estimation of the Passing Sight Distance Requirements [PDF]
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 ...

Analysis of dynamic available passing sight distance near right-turn horizontal curves during overtaking using LiDAR data [PDF]
Canadian Journal of Civil Engineering, 2019 The purpose of this study is twofold: to construct a model for measuring dynamic available passing sight distance (APSD) during overtaking using light detection and ranging (LiDAR) data, and to investigate the effects of several critical variables on dynamic APSD. The analysis considers a single passed vehicle with several variables, including vehicle

Three-dimensional stopping sight distance control on passing lanes of divided highways [PDF]
European Transport Research Review, 2016 Stopping Sight Distance control of passing lanes of divided highways represents currently a discussion point among researchers. A 3-D approach to address the issue is accepted as the overall solution to the problem by both researchers and contemporary design policies.

Research on the length of passing distance in the real traffic flow [PDF]
Građevinar, 2014 This paper presents research and analysis of the length of passing distance in the real traffic flow on the sections of two-way two-lane roads. Values of passing sight distance recommended by road design rulebooks and recommendations are often not ...

TRA-960: FIELD EVALUATION OF PASSING SIGHT DISTANCE PARAMETERS
, 2016 Drivers require a sufficient distance on a two-lane highway to ensure that they can safely maneuver past an impeding vehicle. The passing behaviour of drivers is an important element of safe passing maneuvers. In this paper, field studies were conducted in different countries to determine the passing behaviour of drivers.

An evaluation of the passing process through road - vehicle parameters assessment
European Transport Research Review, 2023 Purpose This paper investigates the interaction between vehicle dynamics parameters and road geometry during the passing process. Methodology The methodology is based on a realistic representation of the passing task with respect to roadway’s posted ...
