The outcome of the 2015 United Nations resolution was to set a series of 17 sustainable development goals, also known as the 2030 Agenda. Each of these goals can be associated with societal, economic, or environmental improvements: Two goals are more general. One considers the institutional setting, particularly the rule

“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Brundtland Report, Our Common Future. The concept of global sustainability is commonly linked with the “three E’s“, which are economic development, ecological development, and social equity (or development).

Author: Dr. Jean-Paul Rodrigue Natural and anthropogenic disruptive events have effects on transportation systems, which can impact modes, terminals, and infrastructure differently. 1. Transportation and Disruptions There is often more to learn from failure than success, even if failure is never welcomed. While the factors behind success can, at times,

Authors: Dr. Jean-Paul Rodrigue, Dr. Theo Notteboom and Dr. Brian Slack Transport planning focuses on the public provision and financing of transportation assets, particularly roads and public transit systems. 1. The Purpose of Planning “Long-range plans engender the dangerous belief that the future is under control.” Max Gunther Transport planning

For a given node, the ego network corresponds to a sub-graph where only its adjacent neighbors and their mutual links are included. The respective ego networks of node 10 (A) and node 8 (B) exhibit similar structures, although their actual situation in the whole network differs significantly (node 10 is

Authors: Dr. Cesar Ducruet and Dr. Jean-Paul Rodrigue Graph theory relies on several measures and indices that assess the efficiency of transportation networks. 1. Measures at the Network Level Transportation networks are composed of many nodes and links, and as they rise in complexity, their comparison becomes challenging. For instance,

Proceedings of the 2009 International Association of Maritime Economists (IAME) Conference, June, Copenhagen, Denmark. Fuel consumption by a containership is mostly a function of ship size

Transportation relies on the use of energy. As most transportation modes rely on the usage of petroleum, a rise in oil prices can impact several dimensions of the transport system. Six interdependent types of impacts can be expected: Usage level. Users of a specific transportation mode generally respond to higher

Source: adapted from The Economist, 2001. Energy use is in constant transition, particularly from a long-term perspective where changes can be substantial. An energy transition involves a change from one supply system to another, namely in terms of the fuels used, their sources, and how they are processed and brought

Economic Costs. Noise levels have an impact on property values, particularly around airports. Declines in property values for residential areas range from 0.4 to 1.1% per decibel, with an average value of 0.62%. For highways, a decrease from 8 to 10% of property values due to noise emissions were observed.
