Taking the modern tram in semi-independent right-of-way mode as the study topic, this paper puts forward the expression formula of carrying capacity calculation under the influence of various factors. In view of the carrying capacity in a section, train running diagram feedback optimized preparation method is proposed to calculate more accurately. VISSIM simulation platform is used to build the network model, set the relevant parameters and operational rules, and establish the tram simulation system. Taking Suzhou tram line 1 as a case study, it is found that the theoretical calculation method and simulation technology method have the identical and similar carrying capacity results. In addition, this paper analyzes the bottlenecks under different schemes and re-verifies the accuracy of theoretical calculation. The study results provide valuable references in the calculation of tram carrying capacity.
