Rules Set

Efficient risk allocation has been proven to be at the heart of effective and efficient infrastructure project operation. While most risks may be reasonably assigned in transport infrastructure projects, demand risk remains ambiguous due to the multiple factors influencing its appropriate allocation. The present research is a first attempt to introduce indicators as tools to guide contracting parties in assigning demand risk. The level of control, based on infrastructure characteristics and attributes, describes the potential control over demand an operator may have. The optimal demand risk allocation is seen as an assessment of the appropriateness of demand risk allocation effected. The indicators are constructed following accomplished rules set by supranational organizations. Furthermore, 51 project cases ranging different transport infrastructure modes from 19 European countries including projects delivered traditionally and as Public Private Partnerships were used to validate the indicators and assess their performance. Results show the potential of both indicators to guide governments, operators and also financiers in appropriately allocating demand risk in transport infrastructure projects. This optimality was shown to be related to more accurate traffic forecasts resulting in sustainable transport infrastructure as the project then delivers on its economic, environmental, and social/welfare targets.

Private Financing

A method to identify the attractiveness for private financing of a transport infrastructure project is presented. The objective of the method is to assist the public sector in identifying the attractiveness of a transportation infrastructure project for private financing, highlighting the factors that tend to reduce such attractiveness and providing the means to examine the viability of alternative risk-allocation scenarios related to risks undertaken by the state or private sector. The method allows for the simulation of the private sector’s attitude toward risk, employing practices of risk assessment in investments. Its innovation lies in how the whole process is structured so that participants understand beforehand whether an agreement can be concluded and which factors involved are critical. A key property of the method is the ease by which priorities of different risk components are synthesized into a hierarchical form through pairwise comparisons. This method, although targeted primarily for the public sector, could assist both private and public stakeholders investing in transport infrastructure projects (termed private-public partnerships) to reach an agreement. Basically, it is an interactive process characterized by the conflicting objectives and judgments of both public and private sectors.

The Global Financial Crisis

In Western liberal democracies the planning of mega transport infrastructure projects is guided by public interest claims typically expressed through legislation and political mandates. But with the infrastructure boom being observed in many cities since the Global Financial Crisis, and the need to address unprecedented levels of urbanisation, the level of politicisation directed at infrastructure projects draws attention to how the public interest is treated in the planning and management of complex mega transport infrastructure projects in diverse local contexts. Looking to Sydney, an advanced neoliberal city building the largest transport infrastructure project in Australian history, we examine how public interest is asserted in a way that reinforces legitimacy of the process and consensus for the project. Under these conditions, planners fail or are unwilling to raise additional or new public interest issues. The vagaries of public interest mean that in being open to interpretation the public interest can be easily captured by the interests of capital and of ruling politicians. This raises important questions for urban studies about the role governments and, in particular, public-sector planners can play in advocating for actually existing public interest issues such as environmental sustainability without it amounting to just rhetoric with no follow through.

In most of the cases the decision to invest in a new large transport infrastructure project t is not simple, mainly, because the complications in planning process, the amount of capital need to invest before the business establishment and the high number of stakeholders involved in decision process. The decision process is more complicated in restricted economic conditions and financing assumptions, where the project business plan performance is strongly related to regional development prospects and business sectors enlargement. This paper provides an attribute methodology approach to support decisions in large transport infrastructure projects based on the effects diversification to ecosystem affected by the new projects. The proposed methodology provides an evaluation framework based on a combination of an ex-ante assessment analysis taking into consideration the large transport infrastructure projects economic impact and its contribution to enlargement of the sectors of the ecosystem.

Background: The realisation of large-scale plans of Russian infrastructure development, transport in particular, requires a corresponding methodological guidance for both planning of realisation of these tasks and development of the proper financing instrumentarium. Aim: The analysis of reasons for incompliance of programme tasks with their financing conditions; formalisation of investment trends in todays economy and description of their capability to adapt to Russian projects. Methods: The method of rising from concrete to abstract and vice versa has allowed identification of important regularities of investment trends and their connection with the quality of projects; the systems principle has confirmed dependence of successful realisation of infrastructure projects on reliability of economic development forecasts and adequacy of projects financing and management. Results: The analysis of ongoing changes of state priorities and programmes, outlined in a large number of documents regulating development of transport infrastructure in Russia, has allowed identification of influence of most significant regularities, which determine effectiveness of these solutions. All available transport infrastructure project financing sources have been systemised, considering investment volume and their status in the market. The statement that it is exactly the loan-based financing sources, concession in the first instance, that can be the most efficient in infrastructure projects realisation, has been confirmed.

A typical feature of transport infrastructure projects is that they are expensive and take a long time to construct. Transport infrastructure financing has traditionally lain in the public domain. A tightening of many countries' budgets in recent times has led to an exploration of alternative resources for financing transport infrastructures. A variety of models and methods can be used in transport infrastructure project financing. The selection of the appropriate model should be done taking into account not only financial resources but also the distribution of construction and operating risks and the contractual relations between the stakeholders.

Megaprojects are defined as projects that cost a billion US dollars or more at 1990 prices. Mega transport infrastructure projects have the potential to affect important socioeconomic and territorial changes. They are often perceived as critical to the “success” of major metropolitan, regional and national development. The redevelopment of neighbourhoods offers many opportunities for regional regeneration, yet there remain concerns regarding the potential gentrification of areas leading to the displacement of existing populations and local businesses. This research applies multi-criteria analysis, a tool that is widely used in mega infrastructure project appraisal using the UK’s Crossrail as a case to explore the likelihood of gentrification and the displacement impacts of the project. This paper finds both positive and negative impacts. Different stakeholders express noticeably differing opinions regarding the project.

In karst regions, due to the heterogeneous features of karst medium, the characteristics of the groundwater flow turn to be of high complexity. Researchers have been seeking proper forecasting methods for karst water dynamic for many years. This paper, taking the spring in Jinan as an example, using regression analysis, analyzed the factors influencing spring water dynamic, and quantitatively evaluated the influencing coefficients of spring water level concerning rainfall, exploitation and recharge as well as the natural decay coefficient of spring water in dry seasons. The prediction model coupling multiple factors was built by investigating natural and anthropogenic factors influencing groundwater level, which could be used for forecasting dynamic of spring water in Jinan. The calculated value of model was highly coincided with the observed value. In consideration of the characteristics of uneven precipitation in Jinan, the suitable zones and volume of artificial recharge were investigated finally, which could help to sustain the spewing of Jinan springs significantly.

The Strategic Choice of Measures (SCM) approach aims to integrate different perspectives and identify measures to adapt new infrastructure projects to their local context at an early stage of Swedish transport planning. SCM is a loosely structured framework for collaboration between actors from, e.g., municipalities and the Swedish Transport Administration, in order to facilitate the coordination of transport planning and land use planning. This paper aims to explore the consideration of environmental aspects in early-stage transport planning by analyzing the SCM approach. An explorative research approach is applied based on literature studies, semi-structured interviews, and a focus group interview. The result shows that in the SCM process, environmental aspects such as noise and air pollution generated by road traffic in urban areas, engage the actors, whereas aspects related to landscape and water were perceived as poorly addressed and received less attention. The consideration of environmental aspects in the SCM process is affected by the local and national authorities’ different interests and the competences involved. To consolidate environmental aspects in early transport planning, these aspects need to be explicitly addressed in the SCM guidelines and the link between the SCM and preceding and following planning stages needs to be strengthened.

Telecom operators’ infrastructure is undergoing high pressure to keep the pace with the traffic demand generated by the societal need of remote communications, bandwidth-hungry applications, and the fulfilment of 5G requirements. Software-defined networking (SDN) entered in scene decoupling the data-plane forwarding actions from the control-plane decisions, hence boosting network programmability and innovation. Optical networks are also capitalizing on SDN benefits jointly with a disaggregation trend that holds the promise of overcoming traditional vendor-locked island limitations. In this work, we present our framework for disaggregated optical networks that leverages on SDN and container-based management for a realistic emulation of deployment scenarios. Our proposal relies on Kubernetes for the containers’ control and management, while employing the NETCONF protocol for the interaction with the light-weight software entities, i.e., agents, which govern the emulated optical devices. Remarkably, our agents’ structure relies on components that offer high versatility for accommodating the wide variety of components and systems in the optical domain. We showcase our proposal with the emulation of an 18-node European topology employing Cassini-compliant optical models, i.e., a state-of-the-art optical transponder proposed in the Telecom Infrastructure Project. The combination of our versatile framework based on containerized entities, the automatic creation of agents and the optical-layer characteristics represents a novel approach suitable for operationally complex carrier-grade transport infrastructure with SDN-based disaggregated optical systems.
