The heterogeneous non-motor traffic flow (including traditional bike and electric bike) is common in China. Existing models fail to reproduce the dynamic and complex interactive behaviors among different non-motorized vehicles under diverse traffic situations, due to the lack of reflecting motivation and decision-making of riders. This paper proposes an integrated “motivation-decision-operation” (MDO) model to settle down the issue. The motivation module based on Comfort-Zone theory divides the Comfort zone of bicycles into five spaces: unaffected space, comfort space, discomfort space, danger space, and yield space. The respectively generated motivations then guide the decision-making process and the operation of behaviors. The model is verified by the travel speed distribution, interspace distribution, features of trajectories and overtaking behaviors, compared with a typical social force model and empirical data. The results show the MDO model is more consistent with the field data than the social force model. Finally, a sensitivity analysis of traffic volume and e-bikes percentage using MDO model is proposed.
