Resilience of Transportation Systems
Source: Adapted from Linkov, I. and J.M. Palma-Oliviera (eds) (2017) Risk and Resilience, Amsterdam: Springer. For a transportation system, resilience is the capability to recover from a disruption to an operational level similar to before the disruption in a timely manner. The longer and deeper the impact of the disruption
Logistics Costs, United States, 1980-2024
Note: In billions of USD. Source: Council of Supply Chain Management Professionals, State of Logistics Report, (after 2012). Logistics Management & Distribution Report (before 2012). The composition of logistics costs is mainly attributed to inventory carrying costs, transportation costs, and administrative costs. The main reason why transportation costs are increasing in
Question #4: Global Infrastructure Connectivity Alliance (GICA)
Q4: The chicken or the egg: What matters more — the impact of trade on connectivity, or the impact of connectivity on trade? Although this question appears at first glance rather tautological, it reflects a much deeper complexity of the relationships between trade and connectivity; which one is the main
Continue readingQuestion #3: Global Infrastructure Connectivity Alliance (GICA)
Q3: Connectivity is comprised of several layers, including physical, virtual, and financial networks. Is multilayer analysis important? How to obtain the necessary data? How can new technologies help? A multilayer approach to connectivity is important since it enables to understand the dynamics of its core components and how they interact
Continue readingQuestion #2: Global Infrastructure Connectivity Alliance (GICA)
Based on your experience, what have been the most important impacts of connectivity? How can we best assess the impacts of connectivity? In prior decades the focus was mainly on developing infrastructures and intermodalism, which were mutually self reinforcing. In my opinion, the container is likely to have been the

As part of a discussion by the Global Infrastructure Connectivity Alliance (GICA), I have articulated an entry on the relevance of connectivity. It seeks to provide elements to the question “In your view, why does connectivity matter? And for whom?” The Relevance of Connectivity
Continue readingThe Relevance of Connectivity
Connectivity is the extent to which passengers or freight flows from a node can reach other nodes directly (direct connection) or indirectly through another node or a series of nodes. It draws from conventional graph theory, which investigates the arrangement of nodes and links in networks. Therefore, connectivity is a
New page: Mobility as a service (digitalization of mobility)
Added a new entry on the concept of mobility as a service, which is mainly the development of platforms able to collect and organize mobility and give options to users. This tries to coordinate the offerings of several transportation service providers. Digital Mobility as a Service

Source: adapted from International Transport Forum (2018) Blockchain and Beyond: Encoding 21st Century Transport, Paris: OECD. The term mobility as a service (or the digitalization of mobility) is used to label the bundling of transportation services to users through an information technology platform. Conventionally, transportation service providers tended to operate within their respective
