Travel behaviour and multimodality: a conceptual framework and critical review of research

Abstract

Promoting alternative travel modes to private cars is a crucial aspect of sustainable transport policies. The integration of different transport modes and services, facilitated by mobile apps and payment systems, has expanded travel options and fostered multimodal travel behaviour. Despite the increasing prevalence of multimodal transport in practice, there exists a shortage of systematic academic research on this subject. This paper seeks to fill this gap by presenting an overview of key themes related to multimodality in travel behaviour, providing valuable insights for both researchers and practitioners. Leveraging an in-depth analysis of 182 relevant papers extracted from the Web of Science database, this paper intricately formulates a comprehensive conceptual framework that delves into the definition and measurement of multimodality. Furthermore, it synthesises recent perspectives and insights pertaining to the factors shaping multimodality and its socio-environmental impacts. The paper suggests several potential research directions in multimodality, including a focus on the supportive environment for multimodal behaviour (termed multimodal-oriented development, MMOD), an examination of the socio-environmental effects of multimodality and MMOD, and an investigation of regional variations in knowledge and practices related to multimodality. By exploring these research avenues, this paper aims to advance our understanding of multimodal travel behaviour and contribute to the development of effective strategies and policies promoting sustainable transportation systems.
