For several decades, textbooks, articles and consultancy reports in supply chain management (SCM) have expounded the virtues of low inventory, just-in-time delivery, single-sourcing, centralization and tightly-coupled processes. Heeding their advice, many companies have effectively implemented...

Tokyo is well known as a rail-oriented city where the huge traffic demand generated from the megacity is well supported by a sophisticated urban rail system. The results of the 2008 Person Trip Survey show that rail’s modal share was 30% as of 2008; the economy of Tokyo is highly dependent on an...

This paper analyses the experience, high incidence, lesson learned and reflections on the issue renegotiations in Latin America, based in the evolution of PPP contracts through the last 25 years. The paper also shows how countries via new PPP laws, regulations, norms and specific platforms can...

In this paper we first consider alternative measures of efficiency. We explain why simple partial productivity measures are inadequate as the basis of overall measures of efficiency, and outline two alternative approaches. The first is technical efficiency – the degree to which output is...

We assembled a large panel of project-level technical and financial data and country-level economic, institutional, political, and governance variables to assess the determinants of private financing of infrastructure in emerging markets and developing economies. Controlling for economic...

Shipping could – in one way - be considered a relatively clean transport mode. This is particularly the case if one takes the angle of emissions per tonne-kilometre. Typical ranges of CO2 efficiencies of ships are between 0 and 60 grams per tonne-kilometre, this range is 20-120 for rail...

The experience of transport systems users, in terms of comfort, reliability, safety and above all convenience, is critical in determining demand for transport services, at least when there is a choice of alternative ways to travel. Convenience is one of the strongest attractions of the private...

The transportation sector is responsible for about 23% of all CO2 emissions globally and 30% in OECD countries with road being the dominating sector for transport emissions (ITF, 2010). National emissions data are rarely disaggregated by freight vs. passenger transport, but an estimate is that...

Ports are no longer perceived as main drivers of urban economic development. A variety of factors have been identified in the academic literature to contribute to urban economic growth, ranging from human capital, entrepreneurial culture, diversity and infrastructure to planning and governance....

This paper presents the results of research recently conducted by the authors on ex-post analysis focused on the long-term economic impacts of transportation system investments in the United States (US). For a variety of reasons, the US has had a tradition of making transport investments to...
