Modelling Vessel Traffic Service To Understand Resilience In Everyday Operations, Gesa Praetorius, Erik Hollnagel, Joakim Dahlman Aug 2015

Modelling Vessel Traffic Service To Understand Resilience In Everyday Operations, Gesa Praetorius, Erik Hollnagel, Joakim Dahlman

Gesa Praetorius

Vessel Traffic Service (VTS) is a service to promote traffic fluency and safety in the entrance to ports. This article׳s purpose has been to explore everyday operations of the VTS system to gain insights in how it contributes to safe and efficient traffic movements. Interviews, focus groups and an observation have been conducted to collect data about everyday operations, as well as to grasp how the VTS system adapts to changing operational conditions. The results show that work within the VTS domain is highly complex and that the two systems modelled realise their services vastly differently, which in turn affects …


Understanding The Landscape Of Overruns In Transport Infrastructure Projects, Peter Love, Jim Smith, Ian Simpson, Michael Regan, Oluwole Olatunji Aug 2015

Understanding The Landscape Of Overruns In Transport Infrastructure Projects, Peter Love, Jim Smith, Ian Simpson, Michael Regan, Oluwole Olatunji

Michael Regan

Cost and schedule overruns are endemic features of transport infrastructure projects. Despite the considerable amount of research within the field of transport and planning in the past thirty years, limited progress has been made to improving the performance of projects. We contend that this will continue to be an issue as long as research efforts focus on the ‘outside view’ with emphasis being placed upon strategic misrepresentation and optimism bias. Understanding ‘why’ and ‘how’ projects overrun, particularly from both ‘outside’ and ‘inside’ perspectives, is pivotal to reducing their impact and occurrence. Thus, in conjunction with the transport and planning literature, …


Review Of Performance Measurement: Implications For Public–Private Partnerships, Junxiao Liu, Peter Love, Jim Smith, Michael Regan, Ekambaram Palaneeswaran Aug 2015

Review Of Performance Measurement: Implications For Public–Private Partnerships, Junxiao Liu, Peter Love, Jim Smith, Michael Regan, Ekambaram Palaneeswaran

Michael Regan

Purpose – The purpose of this paper is to review the normative literature in regard to public-private partnerships (PPPs) and their evaluations, and attempts to investigate whether the Performance Prism is a feasible framework for effective PPP performance measurement. Design/methodology/approach – An in-depth and critical literature review is conducted in this study. Discussion concentrates on PPP features, performance measurement in PPPs, performance measurement in construction, and characteristics of the Performance Prism. Findings – The Performance Prism exhibits a strong ability to capture the distinct features of PPP infrastructure projects and can be considered as a framework suitable for effective and …


Government Institutions And Infrastructure Skills Development, Michael Regan, Jim Smith, Peter Love Aug 2015

Government Institutions And Infrastructure Skills Development, Michael Regan, Jim Smith, Peter Love

Michael Regan

The capacity of state institutions is central to the efficient delivery and management of infrastructure. The paper examines two models for improving the skills of managers in central and line agencies of government for infrastructure procurement and management in emerging economies. The first examines the role of the Public Private Partnership (PPP) unit, a specialist agency equipped with the technical capabilities, transactional experience and budget to provide training and assistance to line agencies for the effective delivery of infrastructure projects. Integrated into this model, and used by several nations, is the use of trained relationship managers to manage service contracts …

Achieving Carbon Efficiency In Construction And Maintenance Of Railway Turnouts, Crossovers And Diamonds, Sakdirat Kaewunruen, Steve Krezo, Olivia Mirza, Yapping He, Joseph M. Sussman Jul 2015

Achieving Carbon Efficiency In Construction And Maintenance Of Railway Turnouts, Crossovers And Diamonds, Sakdirat Kaewunruen, Steve Krezo, Olivia Mirza, Yapping He, Joseph M. Sussman

Sakdirat Kaewunruen

Railway turnouts, crossovers, and diamonds are special track systems used to divert a train from a particular direction or a particular track onto other directions or other tracks. It is a structural grillage system that consists of steel rails, points, crossings, steel plates, rubber pads, insulators, fasteners, screw spikes, beam bearers (either timber, polymer, steel or concrete), ballast and formation. Usually under dynamic and high-intensity impact loading conditions, structural components of the turnout tend to have relatively short lives compared with those of ordinary open railway tracks, resulting in frequent turnout re- construction and maintenance (ranging from every 10 to …


A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru Jun 2015

A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru

Deogratias Eustace

The aim of this paper was to analyze traffic crash data by using a simplified method in determining significant factors that increase the risk of a motorcyclist being fatally injured once involved in a motorcycle crash in Ohio. The concept of overrepresentation, which is similar to relative risk, was used in identifying significant variables associated with the elevated risk of a motorcycle crash resulting into a fatality. The overrepresentation factor (ORF) was calculated for each variable of interest. The ORF offers a simple but powerful procedure of determining whether a certain factor significantly occurs more or less frequently in one …

Better Engaging Communities: Moving Beyond Cardinal Rules, Anna G. Hoover Mar 2015

Better Engaging Communities: Moving Beyond Cardinal Rules, Anna G. Hoover

Anna G. Hoover

“Cardinal rules” and best practice approaches have guided governmental risk communication efforts at chronic risk sites for more than two decades, playing an important role in how those most affected by contamination make sense of risk. In addition to providing information, however, communication approaches themselves can affect community perceptions indirectly, through stakeholder interpretations of the processes by which risk information is shared. It is increasingly necessary to evaluate not only whether risk communication approaches have been effective for increasing knowledge but if, in fact, the ways in which information is shared has had unintended consequences that change how stakeholders perceive …

Book Review, Earthea Nance Dec 2014

Book Review, Earthea Nance

Earthea Nance, PhD (Stanford University, 2004)

Book Review published in the journal Water International (2015) The topic… “The book builds upon Nance’s research and presents a comprehensive account of Brazil’s experience of implementing condominial sewerage.” The topic… “From the very beginning, the author expresses her concerns in escaping from preconceived ideas about conventional and participatory development, positioning her views within a third wave of post-structural development discourse, neither universalist nor relativist, that is neither denying nor overvaluing the social content of development.” Research methods… “Nance manages to do so by integrating different areas of established knowledge and examining her research issue from a privileged historical perspective. …
