The rise of micromobility, particularly shared electric scooters (e-scooters), has introduced significant shifts in urban mobility, offering an alternative to motorized vehicles. The rapid deployment of shared e-scooters could positively and negatively impact the urban transport system. While research on e-scooter deployment is expanding, a structured analytical framework is lacking. This dissertation addresses this gap by employing a two-layered analytical framework to assess the implications of e-scooter deployment at both system and user levels. The data used in this dissertation is an online questionnaire survey in Helsinki Region containing sociodemographic characteristics of e-scooter users and non-users, trip purpose, reasons, their opinion on e-scooter deployment in Helsinki, perceptions towards e-scooters and their implications as well as mode substitution effect of e-scooters. In the first framework layer, to analyze the e-scooter deployment impacts and implications on the system-level mobility, a systematic literature review was conducted to understand the spatial and temporal distribution of e-scooter-related trips in the previous studies. Then, through a descriptive cross-tabular analysis, we investigated the e-scooter mode substitution effect on other transport modes. Furthermore, we analyzed the key factors that affect e-scooter mode substitution for six different modes in Helsinki using logit models. At the user-level layer, we tried to develop different e-scooter user and non-user profiles by deploying a systematic literature review and clustering methodology.
