Source: Oak Ridge National Laboratory. BTS. American Association of Port Authorities. The North American rail transport system has a high level of geographical specialization, with large rail carriers servicing substantial regional markets. Each carrier has its own facilities and, thus, its own markets along the segments it controls. The rail

Author: Dr. Jean-Paul Rodrigue Social and sustainability challenges address a range of issues such as mobility gaps, transport security, and climate change. 1. Societal Challenges The role of transportation in society has been increasingly acknowledged, which goes beyond its economic contribution. Concerns over energy efficiency, safety, and security are becoming

World Economic Forum (2012) New Models for Addressing Supply Chain and Transport Risk. The complexity of supply chains requires assessing the

Source: NOAA, Satellite and Information Service. Global mean sea level change is the outcome of two processes on the volume taken by the oceans on the earth’s surface. First, changes in the quantity of heat accumulated by the oceans and their salinity level will impact the density of oceanic water

The geomagnetic north pole is located approximately at 80 degrees of latitude on Ellesmere Island in Canada. Because of the structure of the earth’s electromagnetic field, a geomagnetic storm creates field disturbances

The boundary between tectonic plates is indicative of earthquake risk and potential disruptions of local transport systems, namely roads, telecommunication infrastructure, airports, and ports. The above map depicts a global distribution of earthquake risk, ranging from a low probability of a significant earthquake over the next 50 years to a

Author: Dr. Jean-Paul Rodrigue Transportation systems are complex assets that are under a governance structure and managed accordingly. 1. Transportation Governance Transportation systems and their supporting infrastructures have become so complex in terms of management and scale of operation that governance models need to be revised. The main circumstances under

Author: Dr. Jean-Paul Rodrigue The resilience of transportation is challenged by congestion and the need to add capacity and better manage existing infrastructures. 1. The Enduring Challenge of Congestion Congestion is likely to remain one of the ongoing issues in transport geography because unprecedented demands for transportation are generated by
