Available in PDF, EPUB and Kindle. Book excerpt: Managing large-scale transportation infrastructure projects is difficult due to frequent misinformation about the costs which results in large cost overruns that often threaten the overall project viability. This paper investigates the explanations for cost overruns that are given in the literature. Overall, four categories of explanations can be distinguished: technical, economic, psychological, and political. Political explanations have been seen to be the most dominant explanations for cost overruns. Agency theory is considered the most interesting for political explanations and an eclectic theory is also considered possible. Non-political explanations are diverse in character, therefore a range of different theories (including rational choice theory and prospect theory), depending on the kind of explanation is considered more appropriate than one all-embracing theory.

Download or read book Explaining Cost Overruns of Large Scale Transportation Infrastructure Projects Using a Signalling Game written by Chantal Cantarelli and published by . This book was released on 2014 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strategic behaviour is one of the main explanations for cost overruns. It can theoretically be supported by agency theory, in which strategic behaviour is the result of asymmetric information between the principal and agent. This paper gives a formal account of this relation by a signalling game. This is a game with incomplete information which considers the way in which parties anticipate upon other parties' behaviour in choosing a course of action. The game shows how cost overruns are the result of an inappropriate signal. This makes it impossible for the principal to distinguish between the types of agents, and hence, allows for strategic behaviour. It is illustrated how cost overruns can be avoided by means of two policy measures, e.g. an accountability structure and benchmarking.

This book was released on 2005 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper focuses on problems and their causes and cures in policy and planning for large infrastructure projects. First, it identifies as the main problem in major infrastructure development pervasive misinformation about the costs, benefits, and risks involved. A consequence of misinformation is massive cost overruns, benefit shortfalls, and waste. Second, the paper explores the causes of misinformation and finds that political-economic explanations best account for the available evidence: planners and promoters deliberately misrepresent costs, benefits, and risks in order to increase the likelihood that it is their projects, and not the competition's, that gain approval and funding. This results in the "survival of the unfittest," where often it is not the best projects that are built, but the most misrepresented ones. Finally, the paper presents measures for reforming policy and planning for large infrastructure projects, with a focus on better planning methods and changed governance structures, the latter being more important."--World Bank web site.

Download or read book Lock In and Its Influence on the Project Performance of Large Scale Transportation Infrastructure Projects written by Chantal C. Cantarelli and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lock-in, the escalating commitment of decision makers to an ineffective course of action, has the potential to explain the large cost overruns in large-scale transportation infrastructure projects. Lock-in can occur both at the decision-making level (before the decision to build) and at the project level (after the decision to build) and can influence the extent of overruns in two ways. The first involves the 'methodology' of calculating cost overruns according to the 'formal decision to build'. Due to lock-in, however, the 'real decision to build' is made much earlier in the decision-making process and the costs estimated at that stage are often much lower than those that are estimated at a later stage in the decision-making process, thus increasing cost overruns. The second way that lock-in can affect cost overruns is through 'practice'. Although decisions about the project (design and implementation) need to be made, lock-in can lead to inefficient decisions that involve higher costs. Sunk costs (in terms of both time and money), the need for justification, escalating commitment, and inflexibility and the closure of alternatives are indicators of lock-in. Two case studies, of the Betuweroute and the High Speed Link-South projects in the Netherlands, demonstrate the presence of lock-in and its influence on the extent of cost overruns at both the decision-making and project levels. This suggests that recognition of lock-in as an explanation for cost overruns contributes significantly to the understanding of the inadequate planning process of projects and allows development of more appropriate means.

Download or read book Leveraging Private Capital for Infrastructure Renewal written by and published by . This book was released on 2019 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public-private partnerships (P3s) can provide solutions to the project delivery challenges faced by state departments of transportation (DOTs) and local transportation agencies in delivering surface transportation infrastructure by aligning risks and rewards between public and private sectors, accelerating project delivery, improving operations and asset management, realizing construction and operational cost savings, and attracting private-sector equity investment. P3s are becoming an increasingly important option for financing and implementing critical improvements to U.S. surface transportation infrastructure. As interest in P3s grows, U.S. transportation agencies and stakeholders evaluating the potential benefits of P3s have raised issues relating to the role of private equity in these transactions. Recognizing the complexity and challenges of structuring a highway or bridge P3 compared to a conventional procurement, the objective of NCHRP Synthesis 540: Leveraging Private Capital for Infrastructure Renewal is to bridge the knowledge gap on the role of equity in surface transportation P3 projects and to document current practices relating to private-equity investments in small-scale and large-scale transportation infrastructure projects.

Download or read book Infrastructure written by Jason R. Baren and published by . This book was released on 2009 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are various definitions of what constitutes infrastructure, but generally infrastructure refers to the large-scale public systems, services, and facilities of a country or region that are necessary for economic activity. The sector tends to be separated into two broad subsets - economic and social. Economic infrastructure includes highways, water and sewerage facilities, and energy distribution and telecommunication networks whereas social infrastructure encompasses schools, universities, hospitals, public housing and prisons. Infrastructure assets are generally characterised by high development costs (high barriers to entry) and long lives. They are generally managed and financed on a long-term basis. Historically it was seen as the role of the government to fund and manage these assets for the good of the population. Today, the role of the government as the provider of public services is increasingly being questioned both in terms of the absolute cost to taxpayers and as to whether a government can deliver the assets as efficiently as a private company competing for the privilege. From the government's perspective there is a strong case for privatisation, where the debt raised by the private partner remains on their balance sheets, not on that of the Treasury's. These factors have resulted in a gradual migration from the public provision of infrastructure to the private sector. The private provision of these assets may take many forms from joint ventures, concessions and franchises through to straight delivery contracts. Essentially the private sector is being brought in to design, build, finance and/or maintain public sector assets in return for long term contracted payments from the government or access to the revenues generated from the asset.

Download or read book Transport Infrastructure in Time Scope and Scale written by Björn Hasselgren and published by Springer. This book was released on 2018-05-23 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the economics of transport infrastructure and the economic theorizing around transport infrastructure from 1850 to today. Transport infrastructure systems are continuously evolving over time. Since the mid-1800s these systems have grown in complexity and outreach. They have been important drivers of economic development but have also been important as economic agents in themselves. Over time transport infrastructure systems have taken on different functions as providers of simpler transport services or more developed value chain components. Transport infrastructure has also been a source for different arguments about economic theory and practice. Transport infrastructure systems are analysed from an institutional perspective where the long-term development of the ownership and financing of the systems, as well as the connection to different policy areas are elaborated. A longitudinal study of Sweden’s transport infrastructure policy is used to exemplify driving factors causing change and transformation of the systems over time with different scale and scope.

Download or read book A High Resolution Yet Scalable Framework for Transport Infrastructure Accessibility Based on Open Big Data written by Xiaoqian Sun and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the last years, open big data has brought many challenges and revealed much potential for transportation research. In this study, we show how large open datasets can be used to accurately estimate the accessibility of transportation infrastructure for whole China, a scale unprecedented in the literature. Hundreds of airports and almost one thousand high-speed railway (HSR) stations serve the tremendously growing transportation demand. These access points to the transportation networks are not equivalently distributed throughout the country. Existing large-scale studies on transportation infrastructure accessibility focus on highly-aggregated forms of land-use area, with travel times from centroids of administrative regions. Other studies analyze spatially-constrained regions with very detailed data. In this study, we design and implement a fine-grained accessibility framework based on large open data sets, which allows us to estimate the accessibility based on grid cells with a resolution of less than one square kilometer. We automatize the computation of free-flow road travel times, as well as, the public transit times, from grid cells to infrastructure elements, by using a scalable routing framework. Based on our experiments, we find that the HSR network for China is much better accessible for the population than airports. Moreover, grid cells with a high population density are much better connected to the Chinese transportation networks than other grid cells. Our methodology is generic in that it can be applied on an even larger scale (whole planet) and with different points of interest.

Download or read book Crafting the Integrative Value Proposition for Large Scale Transport Infrastructure Hubs written by Michaël Dooms and published by ASP / VUBPRESS / UPA. This book was released on 2010 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyzing the way managers plan for the construction of large infrastructure hubs, this study finds that failure to include all stakeholders at the start of a project hampers the timely completion of major projects--and in worst-case scenarios, implementation fails and major projects are shelved. Using new models of stakeholder theory, the discussion compares four case studies: the extension of DHL at Brussels National Airport; the industrial cluster on the Left Bank of the port of Antwerp; the plan for the port of Brussels, to be completed in 2015; and the plan for the port of Antwerp, to be completed in 2030.

Download or read book Is Transport Infrastructure Effective written by Piet Rietveld and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: When in 1989 the authors started research on infrastructure, they did not foresee that this would lead to a long-term involvement in this area. Our beginning happened to coincide with the publication of David Aschauer's article on public capital and productivity, which induced a large flow of publications in this field. Infrastructure has indeed been a hot topic in policy and research during the past decade. It is surprising, however, that the number of monographs on spatial and economic impacts of infrastructure has remained very limited. The aim of this book is to contribute to the literature in a consolidated way. A distinguishing feature of our book is that we analyze infrastructure impacts using various methods (both modelling and non-modelling) at a variety of spatial levels (from local to international). Other special features are that we make ample use of 'accessibility' as a bridge concept between the areas of infrastructure and the economy. Finally, we not only treat transport infrastructure projects as given, as is the usual approach in infrastructure impact research, but we also analyze the factors influencing infrastructure supply. We have adopted a mainly non-technical approach throughout most of the book. This means that it can also be used by readers without a strong back ground in statistics, modelling or micro-economics.

Download or read book Megaprojects and Risk written by Bent Flyvbjerg and published by Cambridge University Press. This book was released on 2003-02-13 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Megaprojects and Risk provides the first detailed examination of the phenomenon of megaprojects. It is a fascinating account of how the promoters of multi-billion dollar megaprojects systematically and self-servingly misinform parliaments, the public and the media in order to get projects approved and built. It shows, in unusual depth, how the formula for approval is an unhealthy cocktail of underestimated costs, overestimated revenues, undervalued environmental impacts and overvalued economic development effects. This results in projects that are extremely risky, but where the risk is concealed from MPs, taxpayers and investors. The authors not only explore the problems but also suggest practical solutions drawing on theory, experience and hard, scientific evidence from the several hundred projects in twenty nations and five continents that illustrate the book. Accessibly written, it will be the standard reference for students, scholars, planners, economists, auditors, politicians and interested citizens for many years to come.

Download or read book The Ripple Effects of Large scale Transport Infrastructure Investment written by D. Persyn and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We analyse the general equilibrium effects of an asymmetric decrease in transport costs, combining a large scale spatial dynamic general equilibrium model for 267 European NUTS 2 regions with a detailed transport model at the level of individual road segments. As a case study we consider the impact of the road infrastructure investments in Central and Eastern Europe in the context of the EU cohesion policy programme. Our analysis suggests that the decrease in transportation costs benefits the regions targeted by the policy via substantial increases in GDP and exports compared to the baseline, and small increases in population. The geographic information embedded in the transport model leads to relatively large predicted benefits in peripheral countries such as Greece and Finland who hardly receive funds, but whose trade links cross Central and Eastern Europe and thus profit from the investments there. The richer, Western European non-targeted regions also enjoy a higher GDP after the investment in the East, but these effects are smaller. Thus, the policy reduces interregional disparities. There are rippled patterns in the predicted spillovers of the policy. In non-targeted countries, regions trading more intensely with regions where the investment is taking place on average benefit more compared to other regions within the same country, but also compared to neighbouring regions across an international border. Using regression analysis we uncover that regions which import intermediate inputs from Central and Eastern Europe enjoy the largest spillovers. These regions become more competitive and expand exports locally, at the detriment of other regions in the same country.
