Safety concerns expressed by micro-mobility users seem to practically constrain the use and flexibility of these new modes.This paper introduces a new, parametric agent-based modeling approach for simulating micro-mobility, using MATSim as a platform.Perceived safety is introduced as a factor, which affects travel behavior of Downstems micro-mobility modes in a car-dominated, heterogeneous, and perceived unsafe road network.To meet the research objectives, different scenarios are simulated, using the city of Athens, Greece as a test bed, to examine the model performance and applicability.

A universal scoring function based on travel time, cost, and safety, is proposed.This study also discusses the concept of unsafe discontinuities.Simulation results show that an unsafe road segment of 500 m long is sufficient to induce evident behavioral variations Extracters and hinder the practical use of e-bikes and e-scooters in the base scenario.The establishment of a cycle-friendly road network leads to significant changes in the chosen routes and decreases the average trip distance for micro-mobility users.

In this case, the simulation process is guided by perceived safety, primarily focusing on formulating safer paths for micro-mobility mode users.Nevertheless, the routing behavior of car users is not modified due to the spatial uniformity of safety perceptions in a car-dominated road environment.
