Bus bunching is commonly noticed in the process of bus operation, to some extent, it would worsen the bus service, and further more affect residents’ travel choices. To cope with this problem, this paper proposed a new passenger arrival model taking into account the usage of bus app, which represents the dynamic passenger arrival distribution and where bus capacity constraints are explicitly considered. First, a bus propagation model was developed to carry out theoretical analysis of the bus bunching problem. Afterwards, the new passenger arrival rule, namely, triangular passenger arrival rule, was obtained by fitting the researching data of the passengers who used “bus is coming” app. Finally, under this law of arrival, a new enhanced bus propagation model was developed. By comparing the simulated results, we found that the occurrence of bus bunching was reduced dramatically and the operation of the bus was more stable, which indicated the benefits of the triangular passenger arrival rule.
