: The paper presents a model designed to analyse port governance. It considers that thestakeholders ability to adopt cooperative behaviors constitutes the key element to portdevelopment. Its focus is on medium-sized European ports and fifteen cases were studied. Eachterritory was first subject to a qualitative survey and analysis of the contents of local stakeholdersdiscourse (over 80 interviews conducted). The material is rich, allowing for the comparisonbetween two or even three ports, yet the delicate nature of the relations brought to light addsconsiderable complexity to the comparison within a larger ensemble. The paper, therefore,proposes a semi-automatic treatment which helps to mitigate this difficulty by means of acomputer model based on graph theory. It involves a modelling system based on the relationsbetween the entities of the system. In this context, the relations between stakeholders wereanalysed in order to create typologies and eventually envisage some standard models ofgovernance. In order to[...]
: While the development of urban public transport (UPT) is considered a priority to promote the ecological transition, the Covid-19 health crisis has affected its operation. It results from constraints on supply, made necessary by travel restrictions and limitations on economic activity during periods of confinement. Existing literature has focused mainly on the use of different modes of transport, changes in mobility practices and the way governments managed the crisis. This article focuses instead on the effects of covid-19 on the supply and financing of UPT, and analyses whether this crisis has given rise to new dynamics in the mobility organising authorities (AOMs). Using data from 95 AOMs (i.e. 35% of all AOMs in 2019) and a survey of some 39 AOMs (14%), three main results are established. First, there is a big fall in fare revenue, whatever the category of AOM in France. However, due to the small proportion of UPT funding paid for by users, this decline is easily offset by a variation in the mobility tax[...]
