In the “transportation” part of GovRegPedia, we will dig into the different challenges through specific topics. Some concepts, such as the nature-monopolistic characteristic and the negative externalities, are common in some other sectors. These fundamental concepts can be found in the glossary. We also made a list of the competition nature and the regulation of the main transportation modes, as well as some public data sources in France. Note that this list is expandable, and we gradually will add more countries. Your contribution is more than welcome. If you want to propose a topic or to add items in the list, please contact the editor.
