The number of overtaking events is considered as an important indicator to measure the level of service of non-motorized vehicles and an important basis for calculating the conversion coefficient of non-motorized vehicles. Diversified non-motorized vehicles traffic flow data can be acquired for analysis through microscopic simulation. The traffic behavior of the overtaking vehicles is emphasized in the existing non-motorized vehicle social force model, whereas the influence of this behavior on the overtaken vehicles is currently ignored. Adjacent overtaking is taken as the research subject. The influence of the overtaking disturbance on the lateral shift distance of the overtaken vehicle is considered to improve the repulsive force between vehicles, and the effect of the space headway on the desire speed is considered to improve the driving force. The avoidance behavior of being laterally shifted and longitudinally decelerated by the overtaken vehicles is reproduced. The effectiveness of the model is verified by the speed-density diagram and the overtaking behavior. The number of overtaking events when the mixing ratio of electric bicycles is less than 25% is obtained by applying this simulation model, the non-motorized vehicles overtaking events model is established, and the corresponding non-motorized vehicles conversion coefficient is calculated to be 0.92.
