Abstract <p>Increasing spatial inequality is observed in Russia at many territorial levels, including within large cities. The most striking expression of the depth of social stratification in urban areas is differences in housing prices, which are often taken as an indicator of inequality due to the lack of other public data. In this article, we investigated the impact of transport accessibility and its characteristics on the socioeconomic status of urban areas, expressed through the average cost of residential real estate, with a case study of Saratov. For this, we aggregated data from 80 000 advertisements for the sale of apartments in the city in 2021, using network analysis methods to assess transport accessibility when traveling by vehicle and by public transport to the city center and with respect to the transport network of the entire city (integral accessibility). According to the results of the regression analysis, the characteristics of transport accessibility (together with the age of buildings) were able to statistically explain up to half of the differences between Saratov districts in the average listing price of residential real estate. Contrary to our expectations, the best predictor of apartment prices was accessibility by public transport to the city center. Every minute away from the historic city center by public transport reduced the average price of a residential property listing by RUB 455/m². The public transport network in Saratov is highly centralized, which does not allow for the full use of the potential of the three transport hubs identified in the study. One of the possible steps towards mitigating territorial contrasts in transport accessibility in the city is the transformation of the bus network with the introduction of new main and feeder (to hubs outside the center) routes.</p>
