AbstractThis paper explores the effect of COVID‐19 on long‐distance transport services in France. These services have been deeply impacted by the different lockdowns imposed. However, until now, few papers have considered this topic. The research examines the long‐distance transportation market before COVID‐19 to understand how it adapted to the COVID‐19 countermeasures. The empirical research is based on a large pool of data pertaining to four transport routes in France from September 2019 to November 2021 for four modes (coach, carpooling, train, and air). Prices and frequencies are the main variables. The study's results must be considered carefully because the pandemic is ongoing. The first finding is the severe crisis in terms of supply during the first lockdown in March 2020. Throughout the rest of 2020 and 2021, services increased slowly, with rail and carpooling recovering to almost their 2019 levels, though this is not yet the case for coach and air services. The second finding is that the dominant mode, rail, enjoys the greatest market concentration, especially in comparison to air, which is still experiencing difficulties because of the reduction in the business market. The last finding highlights the persistence of conventional services during the different lockdowns and the high variability of low‐cost services, which disappeared during the crisis. However, mainly thanks to state financial support, no operator went bankrupt or left the market. Finally, low‐cost services were recovering faster in autumn 2021 than conventional services, thereby increasing their market share. The crisis in the business market may explain the difficulty conventional services face whereas low‐cost services are better adapted to the leisure market.
International audience ; This paper proposes a method to understand saturation in the railways. It will be applied to the case of Lyon‐Paris High‐Speed Line. The method presented enables to test and compare different solutions to cope with saturation. It can be considered as both a tool for decision‐makers and a support to investment choices. ; Ce papier propose une méthode pour conceptualiser la saturation d'une infrastructure ferroviaire. Elle est appliquée au cas de la Ligne à Grande Vitesse Paris‐Lyon et permet de tester et comparer plusieurs pistes de désaturation. Cette méthode peut être considérée comme un outil de décision au service des politiques publiques pour guider le choix en investissements.

There is still much progress to make concerning the French and the European railway networks, both from governance and competitiveness standpoints. This is the conclusion this work lead to. The results from the Enerdata-LET research consortium (2014) illustrate that, considering factor 4 for horizon 2050, the modal shift of demand in transport towards railway could be massive. Regarding this, the situation of Paris-Lyon high-speed line, already up to its saturation level, addresses the issue of the capacity a system possesses to bear new traffics. Two schools oppose there. On one side, the supporters of the SNIT suggest a quasi-doubling of the high-speed railway network, in order to cope with futures needs, whereas on the other side, the "Mobilité 21" commission gives priority to the search of increasing returns from the existing infrastructure. Without claiming to solve the issue, this work attempts to bring up comprehension elements on the interaction between demand and offer in the railway sector.Studying the accordance between an increase in railway demand and offer leads us to question performance. It means being able to define capacity of the railway infrastructure, first. But it also means questioning its limits, which addresses the phenomenon of saturation, also called congestion. Eventually, this all inevitably leads to put into perspective the relativeness of these limits and to question the ways to overcome them. The objective of this research is to apply this issue to the railway system, accounting its specificities. We consider its constitution as a network industry and as a natural monopoly, when considering the infrastructure (infrastructure manager). Without pretending to conclude the debate on governance, we consider that this particularity might influence actors and, thus, performance. We also consider the legal framework at the European scale. One can't question performance without framing the railway sector within its legal context. Then, the main purpose of the analysis stands in the study ...

The paper explores the effect of the competitive tender for users through prices and frequencies in the regional railway passenger market. The analysis is original by an extended perimeter to seven European countries (France, Germany, Italy, Netherlands, Sweden, Switzerland, UK) and a total of 103 routes mixing market open to competition by tendering with market still under monopoly. Data are cross sectional and have been selected for one day. The method is based on an econometric analysis (Sureg) developed for other modes (air, coach) but never yet applied to the rail market and its specificities in terms of competition. For the regional services where competition is "for the market", the competition is analyzed through a dummy as a threat to lose the tender. Intermodal competition is limited to the coach services (dummy) and carpooling services (dummy). Results show that the threat of intra-modal competition can increase price for users but have no significant effect on frequencies. The analysis country by country highlights a similar performance for Sweden and Switzerland in spite of high differences in terms of competition. It suggests that the ability to negotiate contracts of public authorities and political choices can be more determinant than potential competition. Finally, effect of intermodal competition are weak mainly because of a limited offer. Results show that the probability to find a carpooling service increases when prices of train are increasing.
