Trip generation dynamics under the introduction of shared mobility

Abstract

The travel behavior of individuals is significantly influenced by the built environment and travel facilities, impacting trip frequency, destination, and duration. This study aims to explore how these effects vary across different socioeconomic groups, particularly considering gender differences, and how individuals engage with state-of-the-art transport modes such as shared vehicles and bicycles during various stages of their life cycle. Using data from the 2018 Madrid (Spain) Travel Survey, we analyze the differential responsiveness to changes in trip frequency across different traffic zones. Notably, the inner ring provides access to shared vehicles and bicycles. We construct four multinomial logit models for distinct origin-destination trip types (inner-inner, inner-outer, outer-inner, outer-outer). Our findings reveal common factors influencing the decision to initiate new trips, including age group, mode choice, trip reason, occupation, and importantly, gender. A policy analysis indicates that individuals residing in the inner ring exhibit a heightened sensitivity to their life cycle, particularly in the context of gender, impacting their decision-making regarding new trips.
