Overtaking events performed by non-motorized vehicles have a profound effect on the level of service and safety of roads shared by motorized and non-motorized vehicles. With the proliferation of e-bikes, heterogeneity within non-motorized vehicles has grown, which results in the speed of these vehicles spreading out. As a result, the frequency of overtaking has risen, causing the decision-making process and action execution of non-motorized vehicle overtaking to become more complicated to depict. To address this, this research identifies three types of typical delayed overtaking events based on empirical data. For each type of overtaking event, a utility-based multinomial logit sub-lane choice model and conditional probability-based overtaking motivation model are proposed to emulate the overtaking behavior of non-motorized vehicles. The model is calibrated and verified using 490 delayed overtaking trajectories that were captured during peak hours on two typical shared road segments in Shanghai, China. The proposed model is then integrated into a microscopic simulation platform and the simulation results ascertain that the proposed model performs well in estimating travel time, overtaking frequency, and the lateral location of heterogeneous non-motorized vehicles.
