Article
European roads have become increasingly congested over the last decades. Addressing congestion is a multi-faceted issue. In the short term, adequate incentives may shift peak car travel to other times, roads or modes. In the longer term, investment projects should be prioritized to provide an efficient supply of road capacity. This also touches upo...
Article
The fact that ports are nodes in the wider transport network industry is seldom considered when studying the innovation process. To this end, two sets of innovation cases are studied, and findings are compared to the key characteristics of network industry operation. The two sets were selected to reflect the key areas of importance in port performa...
Article
Risk aversion is a core characteristic of investor decision-making, especially with respect to new asset classes, such as infrastructure.

The delivery of transport infrastructure projects may be viewed as a system with many interrelating factors whose interactions define and influence the successful achievement of expected project outcomes. However, transport infrastructure delivery has seldom been addressed under such a systems view. The present research studies the transport infras...
Conference Paper
Transport infrastructure development in recent years has been increasingly "bundled" with co-development and co-financing/investing in activities, believed to be enhancing the viability of the investment's Business Model, BM, for delivery, as additional services allow for a wider revenue base and a divergent revenue risk portfolio. Accordingly, the...

Project credit assessments have been increasingly used in order to evaluate the creditworthiness of infrastructure projects. In light of the benefits that can be achieved from changing the financial basis of such projects during their life-cycle, the accuracy and comparability of project credit assessments become of cardinal importance to the succe...
Book
Over the last thirty years Public Private Partnerships (PPPs) have been used to deliver transport capital projects and services. PPPs are complex arrangements that require a multi-disciplinary approach in order to assure their success, though research on the subject has been fragmented. This book fills the gap in existing literature by providing in...
Article
Full-text available
The construction of road infrastructure is often a difficult issue for many countries. While many developing countries do not have public funds available, other developed countries experience public budget restrictions that limit the country's infrastructure development. Public Private Partnership (PPP) appears to be an adequate mechanism for empow...
Article
Case research, the preferred research tool for public private partnerships (PPP), is performed within a specific context, and any findings cannot be separated from that context. This drawback limits the exploitation of research findings. The present research proposes a methodological framework and process by which the contextual elements of the set...
Article
Full-text available
Greater uptake of intermodal transport is important in improving efficiency and reducing carbon and other emissions. An alternative conceptual model to predict the potential of intermodal freight transport is offered based on flow game theory. Emphasis is placed on predicting the potential of establishing modal and operator alliances. The model is...
Article
Transport infrastructure public-private partnership (PPP) projects are very diverse and complex in nature not only because of their mode-specific intricacies but also because of their inherent economic characteristics that relate to the scope of involvement of the private sector in the project, the large sunk costs incurred, and ultimately, the com...
Article
The scope of the paper is to provide a guiding methodology in the design of public-private partnership (PPP) tendering processes on the basis of the number of potential bidders in the market (existing competition) and their respective transaction cost.

Full-text available
Urban freight vehicles significantly impact the urban environment due mainly to traffic congestion, reduction in road capacity and pollutant emissions. Introducing low emission vehicles is one of the major measures foreseen in alleviating negative externalities. In this context, city logistics may represent a market niche for the deployment of elec...
Article
Public-private partnership (PPP) policy strategies emphasize the ability of PPPs to foster innovation. Evidence reported in literature supports less the inherent quality of PPPs for innovation and more the importance of contributing factors. The contractual agreement is the setting of these factors. In this context, an analytical model based on beh...
