    Effect of the COVID-19 pandemic on crowding aversion in public transport and transport mode choice: The case of Santiago, Chile
    (2024) Iglesias, Vicente; Raveau, Sebastian
    Mode choice modeling has shown a significant crowding effect over travel time perception. But the recent COVID-19 pandemic and the related sanitary measures have changed perceptions of overcrowding on the mode choice. This study aims to quantify these changes through a hybrid discrete choice model using data collected through a revealed preferences survey applied in two time periods in Santiago, Chile. Although the overcrowding aversion was included in the choice model as a latent variable, that had a significant effect on the mode choice of people only for the set of responses belonging to the first time period, which implies a reduction of the initial pandemic impact. Results also show that women and people younger than 35 years old have higher levels of crowding aversion. By analyzing the disutility generated by each alternative mode, it is determined that the bicycle is preferred over the car for trips of distances less than 4 km. In the same way, for trips of less than 3 km, the walk has a preference over public transport. Regarding the marginal rates of substitution between travel and walking time in public transport, for trips of 30 min with an overcrowding level of 6 pax/m2, women over 35 years are willing to trade 2 min of travel for 1 min of walking. When comparing the rates obtained in a prepandemic study, it is obtained that for trips of less than 9 min, people in the pandemic have more preferences for walking over spending time inside public transport.

    Impact of omitted variable and simultaneous estimation endogeneity in choice-based revenue management systems
    (2024) Fukushi, Mitsuyoshi; Delgado, Felipe; Raveau, Sebastian
    The demand models used in revenue management systems applied to air transport are affected by endogeneity. This effect is particularly important in the Discrete Choice Models used in Choice Based Revenue Management (CBRM). Still, the sources and the magnitude of the problem have not been completely studied. In this study, we use simulations to analyze the effect of endogeneity in CBRM air transport applications. We replicate different conditions that generate endogeneity described in the literature: the omission of explanatory variables in the behavioral model and the simultaneous determination between fares and demand. On the one hand, results show that simultaneous determination endogeneity is not a concern if the behavioral model includes complete information of the process, without omitting variables. On the other hand, endogeneity affects the estimation and application of CBRM when variables are omitted, a situation that worsens when the omission of variables is combined with the simultaneous determination between fares and demand. Based on these results, we discuss some practical implications and derive some recommendations for the use of CBRM in air transport.
