Abstract: On the basis of inter-city passenger travel chain, the inter-city passenger transport service process is studied; the Petri net language is used for establishing and simulating the model of inter-city passenger transport service process based on the Visual Object Net++; and the simulation results are used for verifying the reliability of the established model with the theory of petri net, while the model is transformed into a homogeneous Markov chain with the process. The detailed analysis on the city subway of the inter-city passenger transport service process was carried out. By modeling and simulating, the derived value of city subway’s average service time is 18 minutes, while the quantitative analysis focused on the improvement of the links of process, so as to further optimize the inter-city passenger transport service process.

Key words: inter-city travel chain, passenger service process, Petri net, visual object net++
