This book aims to enlarge the understanding of decision-making on mega-projects and suggest recommendations for a more effective, efficient and democratic approach. Authors from different scientific disciplines address various aspects of the decision-making process, such as management...

Because of the prominent position of urban rail in reducing urban transport-related problems, such as congestion and air pollution, insights into the costs of possible new urban rail projects is very relevant for those involved with cost estimations, policy makers, cost-benefit analysts, and...

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...

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...

Managing large-scale transportation infrastructure projects is difficult due to frequent misinformation about the costs and benefits, which results in large cost overruns and benefit shortfalls that often threaten the project viability. This paper explores the explanations for cost overruns that...

This paper examines three independent explanatory variables and their relation with cost overrun in order to decide whether this is different for Dutch infrastructure projects compared to worldwide findings. The three independent variables are project type (road, rail, and fixed link projects),...

In recent years the subject of decision making on large transport infrastructure projects and related institutional issues have received much attention in the academic and professional literature, partly triggered by the book Megaprojects and Risk (Flyvbjerg et al., 2003). This book shows that...
