ABSTRAIT This objective of this paper is to improve the understanding of the increased non-response to transport surveys. We have developed a theoretical model based on the travel demand function and the willingness-to-pay when there is a change in travel price. We consider the non-response as a decision to not reveal preferences. Following the literature, we analyzed multiple causes of non-response through a censored model, called the m-hurdle. We tested and estimated the model on the non-responses given to an income question on a survey about pricing change in Lyon (N = 1,500). We showed that non-response can be explained by both—an economic cause linked to the respondent’s lack of resources and a non-economic cause resulting from a rejection of the pricing solution. To decrease the level of non- response, we propose that attention should be paid to the respondents’ contexts, particularly for those with low incomes.

In a context where the demand and supply of mail and parcel delivery services are undergoing major changes due to the widespread use of the Internet and digital communications, this paper focuses on the accessibility of postal services through the physical retail network. The accessibility constraints applied to the outlets network of Le Groupe La Poste (the French postal operator responsible for the universal postal service and three other services of general economic interest) are based on a "simplified" approach that considers accessibility only in terms of time or distance‐time. This paper proposes to measure potential spatial accessibility by applying postal supply and potential demand dimensions using a two‐step floating catchment area (2SFCA) analysis. Based on an equilibrium between supply and demand through distance function, this method, which is often used in studies of the accessibility of health services, is transposed and adapted into the field of postal activities. It aims to measure accessibility by taking into account the population and population/provider ratio, considering standard postal services provided at service points. While until recently the 2SFCA methods were mostly applied in healthcare contexts, some applications have been developed in non‐health‐related services over the last decade. This paper proposes an original contribution to analysing variations in the accessibility of postal services. Referring to the "primary postal services" (sales of stamps, letters or parcels postage, remittance of postal items, and so on), it outlines the conditions that activities (or services) must satisfy in order to use the floating catchment area method.

Sustainable mobility has been one of the central paradigms of research in the field of transport and mobility for several decades. However, the implications of adopting the concept of “sustainable mobility” for the conduct of interdisciplinary research has been little discussed within the relevant research community. Research in the field of transport and mobility has nevertheless been the setting for major debates in recent years on the question of interdisciplinarity, or even transdisciplinarity, with the emergence of mobility studies as opposed to transportation studies. The objective of this paper is to show, empirically, how researchers who are specialised in mobility and transport issues, but who belong to different disciplines (anthropology, computer science, economics, geomatics, sociology and urban planning) have sought to build an interdisciplinary research project—which is currently ongoing—around the links between the development of coworking, which is a new way of organising work, mobility and sustainability. This paper sets out to highlight cross-fertilisation between disciplines, the issues raised, and the difficulties encountered. As such, it provides an account that is as faithful as possible to our experience of conducting interdisciplinary research in the area of sustainable mobility.

The high-speed rail line (HSR) Ligne à Grande Vitesse Sud Europe Atlantique (LGV SEA) was inaugurated and put into operation on July 2, 2017. Since then, a decrease has been observed in air traffic and in air service frequency on the Paris–Bordeaux route. This paper examines the competition between HSR and air transportation services and the influence of this new transport infrastructure on passenger behavior. Using discrete choice models along with data from traveler surveys, an econometric analysis of traveler demand is conducted, dealing jointly with mode choice and schedule choice between Paris and Bordeaux. Results demonstrate that the variables specifically constructed to represent the schedule delay cost are significant, with late arrival generating relatively greater costs compared with early arrival. This model also makes it possible to evaluate the quality of transport timetable proposed by the transportation operators with the help of market share prediction.

Service quality in relation to frequency, availability, and accessibility is an important issue for the various stakeholders involved in high-speed rail (HSR) projects. The concept of accessibility provides the means to build relevant indicators likely to evaluate the service quality in studies of transportation supply and demand. In this paper, indicators of time available at destination (TAD) are used to measure changes in service quality in rail and air travel between Paris and Bordeaux, France. Furthermore, the paper shows for the first time that TAD is a determining factor in explaining the air-train mode choice.

With the aim of making a city sustainable, this paper evaluates the impact of setting up urban toll on inequalities. We use several indicators (Gini, Theil and Atkinson indices) to measure changes in the concentration of incomes and gravity-based accessibility. In the case of the Lyon Metropolitan Area (France), we simulate a cordon pricing and evaluate its impacts on inequalities. We adopt a comparison-based approach to reduce the bias resulting from the spatial division. In agreement with the literature, we show that different inequality indicators produce contrasted and sometimes contradictory results, both at the scale of zones or metropolitan level. Results from Theil and Atkinson indicators point out introducing a toll can reduce inequalities in the most peripheral zones. Although we observe an accessibility improvement, particularly for central zones, the first ring (adjacent to the toll zone) is the most adversely affected by toll.
