Reliability-based analysis of highway geometric Elements: A systematic review

open access: yesCogent Engineering, 2022
Conventional highway design approaches have primarily focused on the use of guidelines in the design of highways. These design guidelines provide nominal safety where conservative percentile values of the design inputs are used to account for the ...

The Potential Impact of Laser Pointers on Aviation Safety

open access: yesEnergies, 2022
Introduction: Although aviation is considered the safest mode of transportation, the annual number of pilots blinded by laser light cannot be understated. An analysis of the available statistics indicates that it is a widespread phenomenon.

Analysis of sight distance for safe overtaking on road 22, section Mataruška Banja - Ušće, according to the criterion "clean shoulder"

open access: yesPut i Saobraćaj, 2023
Overtaking is defined by the Law on Road Traffic Safety as a traffic participant passing another traffic participant moving along the carriageway in the same direction. Different speeds between vehicles lead to a greater need for overtaking and therefore

Permutation Entropy as a Universal Disorder Criterion: How Disorders at Different Scale Levels Are Manifestations of the Same Underlying Principle

open access: yesEntropy, 2021
What do bacteria, cells, organs, people, and social communities have in common? At first sight, perhaps not much. They involve totally different agents and scale levels of observation. On second thought, however, perhaps they share everything.

Sight distance analyses in road design process: Serbian practice

open access: yesTransport, 2016
New Serbian policies on road design introduce the concept of operating speeds. Decades ago, national policies were based on the constant design speed concept.

Two-Lane Highways Crest Curve Design. The Case Study of Italian Guidelines

open access: yesApplied Sciences, 2020
The main purpose of the research is to evaluate the crest vertical curves radii Rv, not considering a conventional value of the opposing vehicle height h2, but the average vehicle heights h2(m) and the value of the 15th percentile of the height ...

Effect of passing zone length on operation and safety of two-lane rural highways in Uganda

open access: yesIATSS Research, 2017
This paper presents a methodology to assess the effect of the length of passing zone on the operation and safety of two-lane rural highways based on the probability and the rate of passing maneuvers ending in a no-passing zone.

Three-Dimensional Virtual Highway Model for Sight-Distance Evaluation of Highway Underpasses [PDF]

open access: yes, 2018
When it comes to the safe design and operation of highways, sight distance is of utmost importance. The estimation of sight distance must be performed taking the three-dimensional (3D) nature of roadways and related features into account.

Analyses of maximum-speed path definition at single-lane roundabouts

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2018
The process of designing roundabouts is an iterative process through which, in several checks, the design elements of a roundabout get optimized. Existing regulations for roundabouts involve swept path analyses, sight distance analyses and speed analyses

Extent of sight distance reductions caused by rainfall on single carriageway roads [PDF]

open access: yes, 2013
The paper is aimed at probing the extent of sight distance reductions along a single carriageway road caused rainy conditions. Stopping and passing sight distances were investigated under dry weather, light, moderate and heavy rainy condition.
