On the Usefulness of a Combined Mode Choice-Schedule Choice Model: Case of the ParisâBordeaux Rail Line (France)
The high-speed rail line (HSR) Ligne Ă 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 ParisâBordeaux 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
Measure of accessibility to postal services in France: A potential spatial accessibility approach applied in an urban region
International audienceIn 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 âsimplifiedâ approach that considers accessibility only in terms of time or distanceâtime. This paper proposes to measure potential spatial accessibility by applying postal supply and potential demand dimensions using a twoâstep 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 nonâhealthârelated services over the last decade. This paper proposes an original contribution to analysing variations in the accessibility of postal services. Referring to the âprimary postal servicesâ (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
Time Available at Destination: Tool to Evaluate the Quality of Public Transport Service and a Determinant of Mode Choice
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
