Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Driver Compliance With, and Understanding Of, Level Crossing Controls
Journal of Road Safety, 2010 Since the early 1970s, in an effort to improve road safety, Australian railway authorities have made a concerted effort to reduce the number of level road-rail crossings, particularly those controlled by passive devices such as ‘give way’ or ‘stop’ signs.

Analyses of accidents in railway level crossings [PDF]
, 2017 I denna studie har det undersökts hur olycksrisken förändras om vägskyddet i en plankorsning byggs om eller om plankorsningen slopas (byggs bort), samt hur den förväntade samhällsekonomiska olyckskostnaden förändras om olika typer av plankorsningar ...

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method
Structural Concrete, EarlyView.Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Journal of Vinyl and Additive Technology, EarlyView.Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Human factors in the railway system safety analysis process [PDF]
, 2009 Current European railway standards highlight the influence of human factors into railway system’s safety. In spite of this precept the integration is less frequent in engineering practice.

Ungulate substrate use in fauna passages
Wildlife Biology, EarlyView.Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Wildlife Biology, EarlyView.Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.

Wildlife Biology, EarlyView.Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Red light cameras usage on railway level-crossings [PDF]
, 2019 Raudteeohutus on praegusaja maailmas kiirustamise, võimete ülehindamise ja tähelepanematuse tõttu muutunud varasemast veelgi olulisemaks. Raudteeülesõitudel registreeritakse iga-aastaselt liiklus- ja ohutuseeskirjade rikkumisi, mis viitavad vajadusele ...
