A Framework for the Assessment of the Implementation of Mobility as a Service Packages

Mobility as a Service (MaaS) has the potential to transform urban transportation by integrating multiple mobility services into a seamless and user-centric system. However, the impact of different MaaS subscription models on transport demand and system efficiency remains an open challenge. In this research, we propose a simulation-based methodological framework to evaluate the effects of MaaS implementation on users' modal choices, operational performance, and sustainability. The framework integrates discrete choice models for demand estimation and macro-simulation tools for network representation, allowing for the computation of quantities of interest for multiple stakeholders of the MaaS ecosystem. A synthetic urban network is used to test various MaaS configurations, analyzing key performance indicators such as modal shift, and revenue distribution among operators. Results indicate that different MaaS bundles generate distinct effects on travel behavior and system performance, highlighting the need for a structured assessment before implementation.
