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 (versement mobilité), government subsidies and an increase in the contribution from local authorities. Second, the AOMs seem confident about the funding for prospects, through an expected increase in UPT patronage and a stability, or even an expected dynamic, in the mobility tax in the future. As a result, the health crisis does not seem to have encouraged the AOMs to find new resources to finance the development of their UPT services in the medium-to-long term. Third, and finally, the health crisis has contributed to shift travel policy priorities in the AOMs, in particular when it comes to investment strategies, by raising the importance of developing the use of","id":2815881,"source":"Les Cahiers Scientifiques du Transport - Scientific Papers in Transportation - Dernières publications"},{"id":2815873,"description":"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 territorialize the subject, six typical cases out of fifteen were used: LeHavre, Nantes-Saint Nazaire, Dunkirk (France), Gdynia (Poland), Klaipėda (Lituania), Hamina-Kotka (Finland).All these port environments modelled according to a single format (i.e. a graph) led to theapplication of a certain number of metrics which enables them to be compared. Two mainmetrics were presented in the framework of this paper for illustrative purposes: “Density” and“S_metric”. These metrics originating in graph theory, coupled with other indicators (distributionof degrees and number of hubs per port), allowed to measure the relationships' intensity and thedistribution of these intensities among the stakeholders, and to identify the main stakeholders orconversely the least","source":"Les Cahiers Scientifiques du Transport - Scientific Papers in Transportation - Dernières publications","pubDate":"Thu, 09 Apr 2026 14:03:48 +0200","url":"https://doi.org/10.46298/cst.11574","titre":"Modelling the governance of European medium-sized port-cities"},{"source":"Les Cahiers Scientifiques du Transport - Scientific Papers in Transportation - Dernières publications","id":2815872,"description":"This paper tries to identify the anchoring factors for emerging bioeconomy activities in some territories, based on a reading of the logistic constraints of this sector which generates important flows upstream. It is based on an identification of location factors for industries using biomass; a comparison of the petroeconomy/bioeconomy “line” logistics flows and the analysis of three cases of companies: the first one remained anchored after having been bought; the other one quickly relocated; and the third one recently established. This leads to a proposal for the role of logistics governance that can contribute to anchor such activities facing highly international competition, dependent on raw materials price fluctuations and on uneven international","pubDate":"Thu, 09 Apr 2026 14:03:47 +0200","titre":"Industrial anchorage in bioeconomy: what role does logistics governance play?","url":"https://doi.org/10.46298/cst-10947"}]
