Today, with the expansion of cities and the increase in urban population, one of the most important problems people face is finding a solution to reduce the distance and time of their inner-city trips. In this context, the network analysis capabilities in the geographic information system, including the shortest path and the combined use of multi-criteria decision-making models and GIS, can be very effective. In this research, the modeling and spatial analysis of the bus system of Sanandaj city were done in two sections: bus stations and bus routes. By using the TOPSIS decision model, the road network was ranked in terms of the priority of establishing bus stations and suitable locations for bus stations were determined. The results of the TOPSIS model showed that the bus stations do not cover the entire road network. Another model used in this research is the analysis model of the Sanandaj urban road network in the GIS environment to determine optimal routes and calculate the length and time of the routes on the network. By utilizing the communication network layer and creating a smart database, new and optimal routes were identified using the operation of finding the nearest route in GIS. The total number of bus routes after applying the optimal route value algorithm was 2243 meters for the route and 2477 meters for the return route, with a travel time of 20 minutes.
