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

Global Energy Systems Transition
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
Externalities of Noise Pollution
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.
Externalities of Water Pollution
Economic Costs. Commercial fishing and aquaculture are likely to be less profitable when an aquatic ecosystem is damaged. A comparison between the average output of commercial activities, taking into account extraction means (ships, surface cultivated, etc.), over a time period may reveal some indicators about the economic costs of water
Externalities of Air Pollution
The main externalities of air pollution include: Economic Costs. They include a wide range of externalities like damage to property, superstructures and infrastructure, and loss of productivity of people and crops. Acid rains (and depositions), smog, and ozone pollution change the time scale during which investments in infrastructure can be
Estimated Air Pollutants Emitted by Highway Transportation in the United States, 1970-2021
Source: EPA. The most important transport emissions are related to carbon monoxide (CO), Volatile Organic Compounds (VOC), and nitrogen oxides (NOx). Still, transportation plays a marginal role in particulates and sulfur oxide emissions. Due to better engine technology and more stringent standards, the amount of pollutants released on highways has
The Paradox of Mobility and its Costs
Mobility conveys various benefits, including access to employment, goods, and social activities. The paradoxical relation between mobility and its costs is based on the premise that the benefits are derived by the users of transport systems (e.g. drivers) and that the costs are in part assumed by society and the
4.4 – Transportation, Sustainability and Decarbonization
Author: Dr. Jean-Paul Rodrigue Sustainable transportation is the capacity to support the mobility needs of a society in a manner that is the least damageable to the environment and does not impair the mobility needs of future generations. 1. Sustainable Development a. The concept of sustainability The capacity of the

Impacts of Modal Competition and Intermodal Capacity on Transport Supply
Transport supply is commonly assessed in terms of the capacity of infrastructures. Although this dimension is suitable in a number of circumstances, particularly when a single mode is considered, the concept of transport supply must consider circumstances where several modes share the same infrastructure or where intermodalism is the core
