To make up for the defect of a social force model, solve the unreasonable contact between bicycles in model application, and establish a more detailed and real bicycle simulation model, based on the social force model, this paper introduced the concept of cyclist's physiological perception space and combines discrete element method to describe virtual contact between non-motorized vehicles. The influence of different non-motorized lane boundaries was considered and the combined model was built. Finally, the combined model was validated from three aspects:basic graph, riding phenomenon and spacing analysis. Results show that the combined model can better express the bicycle flow and has good consistency with the reality. The reduction coefficients of roadside parking, guardrail, green belt and curb are given as 0.901, 0.928, 0.940 and 0.965, respectively, which can provide theoretical basis for bicycle operation management, facility design and construction.
