Estimating the characteristics of bus transit networks is crucial for optimizing the layout of routes and stations reasonably. Based on the theory of complex networks, this paper employs three model-ing methods-L space, P space, and R space to establish weighted network models for bus transit systems. Gephi software is then utilized to analyze static topology parameters such as node degree, average path length, and clustering coefficient of the network. An empirical analysis of the bus transit network in Zibo is conducted, and comparisons are made with cities of different scales. The results indicate that the degree dis-tribution of bus transit stations in Zibo follows an exponential distribution without obvious scale-free char-acteristics. While the transfer network and route network exhibit pronounced small-world characteristics. On average, residents's travel by bus transit in Zibo need to pass through an average of 13.77 stations and transfers 1.32 times per trip, which meets the current travel demands. However, compared with demonstra-tion cities of China's transit metropolis construction, there are still problems such as insufficient connec-tions between adjacent stations, fewer transfer stations, and limited network stability.
