The paper explores the integration of micromobility into multimodal journey planners (MJPs) as a key step toward improving urban mobility. MJPs are key tools for modern travellers in planning trips from point A to point B using various modes of transport (e.g., tram, bus, train, e-scooter). Micromobility, which includes e-scooters, bicycles and scooters, etc. represents a modern concept and emerging solution based on the use of small and lightweight mobility modes for short distances. The paper defines the role of MJPs in the context of urban mobility and presents their development. Special focus is placed on the importance of micromobility in addressing the accessibility issue known as the “first and last mile” problem. Furthermore, the paper identifies key user challenges and opportunities related to the integration of micromobility, including user acceptance, their travel habits and the balance between individual (user preferences) and societal goals. It also examines challenges related to open data, which are crucial for the realization of high-quality journey planners. Finally, the paper presents guidelines for future research and the development of multimodal journey planners and micromobility.
