Application of passing sight distance in road design

International Conference on Road and Rail Infrastructure, 2018
The regulations determine the minimum length of passing sight distance as the function of design speed. Researches have confirmed that passing sight distance has a positive impact on capacity for relatively low traffic volume. Recent researches show that the definition of passing capabilities as percentage of zones with forbidden passing (no passing ...

Assessing the Risk in the Design of Passing Sight Distances

Journal of Transportation Engineering, 2007
Mostly, design methods in transportation engineering do not address the level of risk associated with the design and use of various highway elements. Passing sight distance (PSD) is an example of a highway operational element analyzed with no risk measures. The aim of this paper is to attach risk indexes to various PSD lengths.

Passing sight distance on two-lane highways: Review and revision

Transportation Research, Part A: Policy and Practice, 1996
Several models have been developed to determine the minimum passing sight distance required for safe and efficient operation on two-lane highways. The American Association of State Highway and Transportation Officials has developed a model assuming that once the driver begins a pass, he/she has no opportunity but to complete it.

Integrated Stochastic Approach for Risk and Service Estimation: Passing Sight Distance Application

Journal of Transportation Engineering, 2012
The geometric design of highway elements is based on a set of standards that do not consider the risk levels associated with these designs. Safety elements including risk measures need to be identified and incorporated into the design process. The focus of this paper is a procedure that can be used by practitioners as a framework to conduct trade-off ...

Verification of the existing model for passing sight distance on single two-lane rural carriageways

2015 6th IEEE International Conference on Cognitive Infocommunications (CogInfoCom), 2015
In 2012, new rural road design guidelines (RAL) has been released in Germany. They define different types of roads including different principles for passing. On new roads with a high road function level, passing is safeguarded by passing lanes. However, passing lanes cannot be recommended as a standard on each road type.

Analysis of dynamic available passing sight distance near right-turn horizontal curves during overtaking using LiDAR data

Canadian Journal of Civil Engineering, 2020
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

Criteria for Passing Sight Distance for Roadway Design and Marking

Transportation Research Record: Journal of the Transportation Research Board, 2010
The need for changes in the criteria for passing sight distance (PSD) used for design of two-lane highways and for marking of passing and no-passing zones on two-lane highways was investigated. PSD models from the AASHTO Green Book and the Manual on Uniform Traffic Control Devices were first compared with models developed in previous research to ...
